Everyone interested in this should know that lasers are extremely dangerous, in that a person's eyesight can be permanently damaged by a focused beam of laser light of even a fraction of a watt. Even a brief glint off a shiny object can blind a person. Researchers in the field always wear protective goggles for this reason. These things should not be used as toys. I know because I worked in the field. Our rule was this: if you can see the beam, you are at risk. Our joke was: Do not stare at beam with remaining eye!
Yeah that is the crappy part about powerful "La-sers". You slip one time with the safety glasses, and boom, your blind. That is no fun. I did a lot of service work for a company that produces communication lasers. They always let me dig through their electronics waste bins. I could have had all the power supplies and laser diodes I wanted. However You just can't show it off Willy-nilly . That's probably why XM360 made his awesome CZcams channel.
The general public can buy like 50+ Watt laser tubes albeit c02 tubes so you cannot see the ir laser beam they are mighty powerful they are essentially the laser tubes you would find in a c02 laser cutter machine :)
I don't have to imagine classified's lasers' power, I know. Unfortunately I can't share this information publicly, but just trust that if I said what they can do, you would say "No. That's impossible. Lasers can't do that!" Think of it this way: multiply your most crazy optimistic pie-in-the-sky fantasy by 10X. Lasers aren't just for pointers any more. Now they can melt a desert into a glass-art in a micro-second. "Building? What building? Why it was just there a second ago." Now, back to more manageable 1W to 5W: Hedge trimming. Think about it, you don't need that pole cutter. Use the laser. So long as you've got a hose nearby, topiary will become commonplace.
@@saltysteel3996 Yeah, like I mentioned, I know some of the real stuff out there nobody talks about, can talk about. 5000 watts won't do what I'm talking about. 5000 watts will cut 1" steel. What I'm talking about eclipses that more than an order of magnitude. More than two. Imagine the amount of power required to punch through 6" of concrete and you aren't even close yet. It's best not to think about it in terms of wattage. That just constrains the imagination. For wattage, just think "many, many, many watts" & don't fret about how that is done.
@rvidal0001 10w diodes are only available in cnc cutters and engravers...you can buy 15w ones now but nothing handheld is above 7w at this time due to the heat and power supply. You could buy a 10w and driver but it would quickly burn out without proper cooling. This 7w has a very short cycle of 60 seconds on/off. CNC lasers have fans and cooling fins etc and can only be on a couple three minutes or so. My buddy got one for his XY CNC and it's maximum run time is 5 minutes and even then it's literature said the diode could fail and recommends projects that can be run in only 3 minutes. There are sophisticated cooling options but they take up whole long tables and are impractical.
_This laser is absolute crap. The beam quality is trashy and the speed of it burning things reflects that. His vid on the 4w laser shows a better quality beam. I'm glad I watched this vid. I wouldn't give $20 for this laser._
@CassidyCash _Yep, I can imagine Drake (Styropyro) out in the woods, lying back in a lounge chair, laughing in his "Annoying Orange" laugh, while picking off Elon Musk's Starlink satellites with one of his lasers. xD_
Let's also mention this unit will blind your enemies permanently in 2 tenths of a second. Add a star adapter and you can blind 50 of your enemies in 2 tenths of a second.
How long did the diode worked before? Do you think, that the diode died because of an inner overheat? Told about the little high-energy handhelts, that there cannot happen enough cooling, therefore die fast. But the bigger like such in the video and for such a price... 🤔😐 My god... :/
I have their 3 watt Silver Series in 445nm and that’s pretty amazing and quite scary at times to use. Never ceases to amaze but 7 watts! Incredible! Great review by the way. :)
These class 4 lasers are exceptionally powerful. A single small mistake WILL result in permenant eye damage or blindness. I always use a heavy tripod and don't causally wave the laser around. I also prefer a good beam stop like a cliff or a tree and one must always do a proper aircraft check to insure no aircraft are in the air near where you are poining the beam. They are amazing tools and I love class 4 lasers of various wavelengths. Use to only have the 445nm burning lasers now were seeing 470 which is just awesome! Always wear properly rated safety goggles when setting up. As XM360 said these things are no joke!

I've got a 470nm 5 watt Sanwu Striker, and I can definitely say these lasers are weapons, every time I turn it on I am absolutely astounded. You can't go wrong with Sanwu.
I ordered this one at 7w single mode. Came to 475 with batteries and charger. I have a 1.5w and a 5W I built but the 5W driver only gets it up to about 3.5w, they both burn nicely and blow my mind they can be hand held. Waiting for it in the mail, they emailed me they take 5 to 10 days to ready or make the laser to order then shipping...so excited!

Great review, convinced me to buy my own 7W Striker! But my experience has been different to yours. With the Beam Expander I am getting a nice, more or less circular dot at 500 yards plus, nothing like the line you were getting on your rock wall at around 150 feet. I guess you know the beam expander is adjustable? It has an adjustable thread in the middle. If you unscrew the thread all the way out, then attach it to the laser and steadily screw the adjustment back in, you should get a highly concentrated spot, no trace of that power sapping divergent line as seen in your video. Of course there may be some variation between individual Striker lasers which could account for your result. My only minor gripe with this laser is that the focus adjustment on the front of the host is a bit sharp and somewhat painful on the fingers. Otherwise this is an amazing piece of technology and every laser enthusiast needs one! OF COURSE IT IS ABSOLUTELY ESSENTIAL THAT ANYONE USING A LASER OF ANY POWER USE SAFETY GLASSES AND NEVER EVER POINT THE LASER AT ANY LIVING CREATURE OR AIRCRAFT, THIS IS NOT A TOY AND CAN CAUSE INSTANT BLINDNESS!!
Mines in the mail as I type! I have a 1.5w blue and a 5W blue...expecting this 7w or 7.5 actually to blow my mind.

weirdyoda04 you can’t get eye damage from your screen by a video of a laser, the brightest thing your screen can display is the color white your eyes are perfectly fine
Yeah the 303 lasers are like 14$ on ebay. They wont burn anything.at least my green one wouldnt.. Blue is extremely dangerous. A 7watt handheld is wicked dangerous... its too easy to blind yourself or others with it. Even looking at my 303 green on my wall hurts eyes
Wow....Scary powerful is cool and I'm in awe of this, but I'd like to see you get your hands on and review more exotic wavelengths. I really want to see a 488nm 😊
The last laser I dealt with was 7/100 of one watt and it plugged into a wall outlet. It was the size of a weirdly shaped loaf of bread (3 inches by 3.5 inches by 15 inches, roughly) and weighed a couple of pounds. I was told it used 2 one-way mirrors facing each other.
When you think about it just a few hundred years ago in New England (or anywhere else in the world) this device would have branded you as a sorcerer and probably burned at the stake. Nowadays being able to burn things at a distance is no longer magic. It is really fun, but no big deal. If someone asks you, "are you a wizard?", just smile and say yes.
Robert the Robot thank. Great vid. Unfortunately there's been a disturbing trend of labeling science and math as racist. Maybe we will be chucking spears at each other in 10000 years.
Nobody will brand you a wizard because lasers didn't exist in the late 1600s. They're almost ubiquitous today, though. Every checkout lane, every dvd player, CD player, etc... has one. Being able to burn things at a distance was never magic because it wasn't even possible before the invention of the laser in the mid-20th century, and by then, people were well acquainted with radios, rockets, television, atomic bombs, etc... I'm sure the first consumer lasers were quite a hit at parties, but nobody ever invoked any mystical quality as long as they've been around.
Yikes, I forsee alot of little brothers growing up blind from sneaking into bedrooms to snoop through stuff. I suppose suggesting storing it without the batteries in it would also be wise. How is it for hare cuts, Doc?
Note: Some old 3 W versions sold at Bangkok markets were infrared on the actual output and visible was the 1st harmonic as blue. No toy to given into layman's hands.
I think its engineered to expand the width at distance,because you could imagine the nut cases aiming at a pilot of a plane what could happen.Or in Australia when in the summer time it is very hot and very dry,we have bush fires that ass holes set on fire on purpose.
Got a 3Watt green laser for my reflective telescope,and its pretty powerful, cant imagine what you would do with 7watt. Anyways looks cool, the light sabre motif would really make it hard to not go all Jedi warrior.
Those high power 445nm multimode diodes are horrible with fast axis divergence. Beam expanders help a lot. Camera zoom lenses work well if you can fit one to the laser. Little loss but still powerful! I actually use mine as a thermite igniter. Thermite is difficult to ignite, not with a 445 or even 405nm laser. 1W is all that's needed if close and focused, 4+W is needed to ignite from a reasonable distance when focused to infinity.
XM360 it’s in my wish list too! I imagine it’s incredibly visible but just wonder what the beam profile is like over a distance. Hope your wish comes true!! :)
Wow i don't like that you have absolutly no beam at long distances. and for $50 more it should fix the beam completely. I'm glad you did this preview cause I don't want it now. Thanks for saving me the money.
BadRonald1 it must suck to be stupid? Consult your favorite astrophysicist and get back with me! A red 5mW will hit the moon, our puny eyes can’t seen it. Yada yada some beam expansion. Any way, this is a 7 watt laser and this video never shows the right lens to pinpoint the beam at its peak point. I don’t usually argue with stupid but I’ll take you on this once. Do you know how fast light travels? Type less, research more.
BadRonald1 that’s exactly what I’m saving CZcams from....false knowledge. You’re original statement, is false. I own one, this thing will diverge closer into one than you think. You don’t own one with a lens. Don’t speak when you don’t know.
Interesting stuff. I just got a 3w 450nm and am being very cautious using it. This one looks like a potential future purchase but I want to learn a bit more about them and safe use of them. Cheers!
3w! Very cool, I first got a 1.5w blue then 5W blue...ordered this 7w! My 1.5w is a burner and emgraver. Be careful with that 3w friend...serious laser!
I have several lasers. This one is pretty nice. I've built many larger ones exceeding 100w as well. On my channel. I wear ThorLabs LG10C model goggles (220$ OD7.8 @ 445nm) Safety should always be taken extremely serious with these. One wrong glint outside off something shiny will probably scare/startle you bad enough to dropping it....seeing that much luminal power zipping around... Its wicked and scary. I have a 85w...105w...and a 74w handheld I built myself. And a Barnnet 7w handheld similar to this. But this one is a little nicer machined wise. But performs wonderful. And is nice looking as well.
Question: With this and many other lasers being so dangerous to view without quality safety glasses how much danger does this laser pose to anyone near me when I point it up into the sky or just using in any conditions? Do onlookers also need safety glasses?
This is so obviously a powerful laser. That being said I am looking for strictly a self-defensive tool for my home. A good 12 gauge shotgun is nice, but since these should be considered and handled like a firearm, is this a good self-defense option?
It has already been done with less powerful blue laser, there's a photo on here somewhere, saw it some time ago. They had to use some special robotic arm and complex calculations to be able to adjust for the movement of the iis and hold it pointed precisely at it for some short time.
I've thought about it before. Lol! Yes, very good chance it could be seen from the live view cam. No jail or legal issues. Beams divergence would be a few miles wide at 300miles but there will still be enough photons available for the sensor to register. Just make sure it's not an aircraft!
ok just a quick correction, beam expansion doesnt depend on power levels. it depends on frequency, beam waste (actual laser rod) or focusing lens. doesnt depend on power.
I'm new at lasers as i just got my first 303's but have been interested in them for ages. What keeps me from buying the 7W Striker is the price, the shape of the beam at long distances (even with the expander) and the stupidity of people as you can be sure you'll be in trouble over here even if you just aim it at the sky avoiding planes... I'll probably buy one eventually, just hope they don't discontinue it for some reason.
PLEASE believe me when I say I’m not being sarcastic or trolling. This is exceedingly cool (no pun intended), but I’m not sure what this is for. Is there a practical use? For just fun, demonstrations, and experimental purposes, I guess I get it, but it seems there’s so much potential downside to using it. A powerful device, to be sure!
oh yeah let me just ask my attacker to just hold still so I can shine the laser in his eye for a good 3 seconds lol I guarantee you this kid if I attracted him could never be able to blinded me what so ever.
@@patman0250 you are not as smart as you think. Think out of the box, this laser has tremendous use, obviously you would not use it like you would a gun and there is a greater purpose beyond using it as a pointer or to burn paper.
_Thank you for reviewing this laser. I almost bought this one. I'm glad I watched this vid first. This laser may be 7w but it's beam quality is really trashy and the speed of your burning things reflects this. It seems no better if not worse than a 4w laser._
This is a great piece of electronics. I question as to what was the reason you bought it for? OK, It looks cool and it lights things on fire and it's got a great looking beam. Here is the top question of the day. What are you going to do with it? It cost you money. Is it just one of those things your glad you bought it just because you wanted it.
Only downside to this lazer, if you so much as turn it on, ,'they' will know where you are. Kool unit tho. Can think of a number of useful purposes for it.
They have the beam expander to remedy that. Styropyro uses the same diodes, all diodes have this it's just a matter of using the right lenses to elevate and direct the beam.
So I work in the defense industry. Missile defense systems and smart bombs. There is some public information on some "low powered" 5000 watt military lasers that can pin point the beam at miles away and burn holes through metal drone targets in just a few seconds. So I'm wondering why the 7 watt laser couldn't have less beam spread at such short distances? Wicked Lasers have 3 watt units that have very little beam spread at very long distances. This 7 watt unit just seems like cheap Chinese manufacturing with low quality, only trying to squeeze out as much power as possible through this diode. Nice looking machining on the housing though. Looks cool, kinda like a Jedi lightsaber.
WOW!!!! What an Incredibly Powerful, and dramatic, impressive looking device! Great review!!! I wonder how many accidental fires might result from careless use of such a tool?! GEEZ!!!! => BE CAREFUL out there!!!!
Nice calll...very cool! I remember 5watt lasers in the mid 90s costing 5k usd up to 10k! Those were he ne lasers. I built a .5mw in 7th grade that cost 500usd just for the laser tube!

Wow....Scary powerful is cool and I'm in awe of this, but I'd like to see you get your hands on and review more exotic wavelengths. I really want to see a 488nm 😊
Oh believe me, it's on my wishlist!!
i just got mine. its brightness is equal parts terrifying and badass.
Hi can you plz tell me how to switch out the lense?
How far away can it burn a paper or a match?
Finally you got it! Congrats bro :)
Thanks a lot!
With the beam expander it looks like a real light saber.
That's the kind of laser that makes you want to dress in your Jedi wardrobe, drop some dry ice in the bucket, and pull out the Kodak :D
And accidentally blind all your friends...
Feel ya on that one. Hopefully you're smart enough to give them laser glasses and do it outside.
What's a Kodak?
Very cool video. What type of
protective glasses are needed for the Zeus X 7 watt 450nm laser
pointer?
Thank you for the detailed content , nicely done thanks for posting !
The last laser I dealt with was 7/100 of one watt and it plugged into a wall outlet. It was the size of a weirdly shaped loaf of bread (3 inches by 3.5 inches by 15 inches, roughly) and weighed a couple of pounds. I was told it used 2 one-way mirrors facing each other.
Could of just said 70mW to make it so much easier to understand

Nice review. It's too bad that the laser goes wide too fast.
Well wildfires may not be caused by "your" laser...they are caused by lockheed martin's...
Bahaha
Good one california learnt that from the ir lasers
There are many videos showing lasers doing just that. Were California wildfires an inside job?
Raymo_2_u Ask any Californian....
@@goodwilj In short. Yes
Thanks for the review! The diode they use is actually a Nichia NUBM08 with the gball removed (open can).
More Like Nichia NUBM44 (the NUBM08 is 4,75 Watts) but yeah kinda
P.s.:the NUBM44 has 7 Watts of Power ;)
few days back i encountered videos showing striking lasers on airplanes are bad, now I'm getting this on my feed
interesting
Looks like a Light Saber. :)
Dude your mind is in the right place
XM360: I’m actually afraid a laser of this power will burn my house down
Styropyro: *Shines 200W laser bazooka all over workshop
XD
What about the handheld 200W unit?
Great for pointing out exotic objects in the night sky.
What do you mean exotic?
I will use mine for signalling my nordic gf...

When you think about it just a few hundred years ago in New England (or anywhere else in the world) this device would have branded you as a sorcerer and probably burned at the stake. Nowadays being able to burn things at a distance is no longer magic. It is really fun, but no big deal. If someone asks you, "are you a wizard?", just smile and say yes.
Rascal77s you would like exurb1a's video "10,000 more years of the scientific method"
Robert the Robot thank. Great vid. Unfortunately there's been a disturbing trend of labeling science and math as racist. Maybe we will be chucking spears at each other in 10000 years.
That's why you just shine the laser in their eyes and stop them from burning you hahaha
Burned at the stake? Not if you burn them first lol
Nobody will brand you a wizard because lasers didn't exist in the late 1600s. They're almost ubiquitous today, though. Every checkout lane, every dvd player, CD player, etc... has one. Being able to burn things at a distance was never magic because it wasn't even possible before the invention of the laser in the mid-20th century, and by then, people were well acquainted with radios, rockets, television, atomic bombs, etc... I'm sure the first consumer lasers were quite a hit at parties, but nobody ever invoked any mystical quality as long as they've been around.
I recommend the 800mW 532nm PLE PRO from jetlasers that will go over 1 watt
Yikes, I forsee alot of little brothers growing up blind from sneaking into bedrooms to snoop through stuff. I suppose suggesting storing it without the batteries in it would also be wise. How is it for hare cuts, Doc?
I have one of these and with the beam expander i can focus it into a dot at over 100 feet away so it just depends on the person who builds it
CAN YOU IMAGINE WHAT KIND OF LASERS THE MILITARY USES OR DARPA ??
Jigglewatts
Laser weapons are banned due to unnecessary suffering, ie blindness and extreme burns
Lol Bro nah the navy has laser systems on their Boeing’s that can burn down missiles and drones
gigawatts not jiglewatts
i can tell youre new here, let me be first to say no shit sherlock.
Wooohooooo! Not Your Father's Mountain Ale. That's some pretty good stuff....
You know it!
" I don't like to operate this Laser indoors " - Instantly buy.
Nice video, Sanwu definitely make some quality stuff.
Good Job, I like your info!
Visible blue beam in daylight, that's insane.. Nice review!
Great review, thanks for sharing!! 👍
Glad you enjoyed!
Note: Some old 3 W versions sold at Bangkok markets were infrared on the actual output and visible was the 1st harmonic as blue. No toy to given into layman's hands.
I guess there is no way to distinguish the old from the new one right ? Having a 3W IR laser without having to pay 3W IR laser prices would be nice .
Looks cool! I’m the guy that bought the nano s
Glad you like it!
Excellent review!
I think its engineered to expand the width at distance,because you could imagine the nut cases aiming at a pilot of a plane what could happen.Or in Australia when in the summer time it is very hot and very dry,we have bush fires that ass holes set on fire on purpose.
Just got this laser and I’m in love!!!
How far away can it light a match?
fascinating that this made it through customs. Extremely dangerous to the eye
Simon Theodore .....where's Alvin?
Can you burn a gas station from a security distance with one of these? 😁😁💥🔥
Got a 3Watt green laser for my reflective telescope,and its pretty powerful, cant imagine what you would do with 7watt. Anyways looks cool, the light sabre motif would really make it hard to not go all Jedi warrior.
moeshickenyay i can...
Why you need 3watt laser for telescope 💀
Thank you for great review
Those high power 445nm multimode diodes are horrible with fast axis divergence. Beam expanders help a lot. Camera zoom lenses work well if you can fit one to the laser. Little loss but still powerful! I actually use mine as a thermite igniter. Thermite is difficult to ignite, not with a 445 or even 405nm laser. 1W is all that's needed if close and focused, 4+W is needed to ignite from a reasonable distance when focused to infinity.
Chris Barth why am I thinking 911?
This is the most expensive motorcycle ashtray I have ever seen.
Keep on those great vids
That’s a beast of a laser! Have you got plans to review a Sanwu 1watt 520nm laser? There are not many reviews of that wavelength and power.
Ya, hopefully I can get my hands on one soon because it's veryyyy high on my wishlist
XM360 it’s in my wish list too! I imagine it’s incredibly visible but just wonder what the beam profile is like over a distance. Hope your wish comes true!! :)
Would love to see!
Wow i don't like that you have absolutly no beam at long distances. and for $50 more it should fix the beam completely. I'm glad you did this preview cause I don't want it now. Thanks for saving me the money.
This thing will nearly hit the moon. Idk what you’re talking about, I own one.
Your little pee wee laser would not even shine a quarter of the way let alone go 238,000 miles. Come on get your facts straight man.
BadRonald1 it must suck to be stupid? Consult your favorite astrophysicist and get back with me! A red 5mW will hit the moon, our puny eyes can’t seen it. Yada yada some beam expansion. Any way, this is a 7 watt laser and this video never shows the right lens to pinpoint the beam at its peak point. I don’t usually argue with stupid but I’ll take you on this once. Do you know how fast light travels?
Type less, research more.
Seeing your denigrated personality only shows me insolence. Beware of false knowledge, it's more dangerous than ignorance.
BadRonald1 that’s exactly what I’m saving CZcams from....false knowledge. You’re original statement, is false. I own one, this thing will diverge closer into one than you think. You don’t own one with a lens. Don’t speak when you don’t know.
Interesting stuff. I just got a 3w 450nm and am being very cautious using it. This one looks like a potential future purchase but I want to learn a bit more about them and safe use of them. Cheers!
3w! Very cool, I first got a 1.5w blue then 5W blue...ordered this 7w! My 1.5w is a burner and emgraver. Be careful with that 3w friend...serious laser!
Did you try it yet?
Chuck Norris was facing the beam in his eyes for 4 mins straight and then the diode died...
I have several lasers. This one is pretty nice.
I've built many larger ones exceeding 100w as well. On my channel.
I wear ThorLabs LG10C model goggles (220$ OD7.8 @ 445nm)
Safety should always be taken extremely serious with these.
One wrong glint outside off something shiny will probably scare/startle you bad enough to dropping it....seeing that much luminal power zipping around...
Its wicked and scary.
I have a 85w...105w...and a 74w handheld I built myself.
And a Barnnet 7w handheld similar to this. But this one is a little nicer machined wise.
But performs wonderful. And is nice looking as well.
You've gotta love the Chinese!
What would we do without them
@@oofig not having a coronavirus pandemic, for example
@@Malkus1 EXACTLY...!
Wake me up when it'll be 7 gigawatts.
hztn if you want that get a pusle laser
Yeah the laser form the star wars death star
Well then we won't need gamma rays I believe ;-)
Question: With this and many other lasers being so dangerous to view without quality safety glasses how much danger does this laser pose to anyone near me when I point it up into the sky or just using in any conditions? Do onlookers also need safety glasses?
Holy shit, us humans have litteraly made lightsabers
Someone saw a mechanical Vape mod and said "hmmm..."
What the vape is this... :)
For vaping nicotine...that kind of vape. Hehe...picturing someone vaping their face off with a 7w laser...major vape fail!
Can these laser be used to protect themselves from certain situation under attacks or emergency situation?
Yes. Ita good for defense for sure especially a shooter
That beam divergence is shocking.
This is so obviously a powerful laser. That being said I am looking for strictly a self-defensive tool for my home. A good 12 gauge shotgun is nice, but since these should be considered and handled like a firearm, is this a good self-defense option?
KING KHAN KHAN what are you even trying to say?
So this can be used to laser point the ISS in space and see it on live feed?
It has already been done with less powerful blue laser, there's a photo on here somewhere, saw it some time ago. They had to use some special robotic arm and complex calculations to be able to adjust for the movement of the iis and hold it pointed precisely at it for some short time.
Yep, and then spend a year in jail.
@@flagship1701e try 20
I've thought about it before. Lol! Yes, very good chance it could be seen from the live view cam.
No jail or legal issues. Beams divergence would be a few miles wide at 300miles but there will still be enough photons available for the sensor to register. Just make sure it's not an aircraft!
@David M Yes, the beam width and height will
keep the same ratio with distance. Need a single mode diode for a better beam but they still diverge.
Damn you really have to treated like a lightsaber
ok just a quick correction, beam expansion doesnt depend on power levels. it depends on frequency, beam waste (actual laser rod) or focusing lens. doesnt depend on power.
I'm new at lasers as i just got my first 303's but have been interested in them for ages. What keeps me from buying the 7W Striker is the price, the shape of the beam at long distances (even with the expander) and the stupidity of people as you can be sure you'll be in trouble over here even if you just aim it at the sky avoiding planes... I'll probably buy one eventually, just hope they don't discontinue it for some reason.
PLEASE believe me when I say I’m not being sarcastic or trolling. This is exceedingly cool (no pun intended), but I’m not sure what this is for. Is there a practical use? For just fun, demonstrations, and experimental purposes, I guess I get it, but it seems there’s so much potential downside to using it. A powerful device, to be sure!
That's like saying there's a downside to owning an AR15. Most ridiculous thing I've ever heard.
Practical use: defense, you can blind your attacker.
not really moron an ar15 has a use this laser does not . like it really doesn't the only thing you can do is just point it at things .
oh yeah let me just ask my attacker to just hold still so I can shine the laser in his eye for a good 3 seconds lol I guarantee you this kid if I attracted him could never be able to blinded me what so ever.
@@patman0250 you are not as smart as you think. Think out of the box, this laser has tremendous use, obviously you would not use it like you would a gun and there is a greater purpose beyond using it as a pointer or to burn paper.
my girlfriend has one just like that...oh ...thats a laser
LMAOOOOOOOOOOO
Laugh my as of
Holy Shit that's funny!
Lee Donald a clit inducer 😂🤣😂😂
Sadly this laser is not available in the US at this time. I went ahead and built my own using the new NUBM44 V2 diode. Be safe...it's truly powerful.
Plus it does light gas on fire too
_Thank you for reviewing this laser. I almost bought this one. I'm glad I watched this vid first. This laser may be 7w but it's beam quality is really trashy and the speed of your burning things reflects this. It seems no better if not worse than a 4w laser._
it’s amazing
This is a great piece of electronics. I question as to what was the reason you bought it for? OK, It looks cool and it lights things on fire and it's got a great looking beam. Here is the top question of the day. What are you going to do with it? It cost you money. Is it just one of those things your glad you bought it just because you wanted it.
In a way you are right. Not many practical uses I have for it; simply an addition to my laser collection & hobby
Disclosure was made, in the video. It was Given to him in exchange for an honest review.
Only downside to this lazer, if you so much as turn it on, ,'they' will know where you are.
Kool unit tho. Can think of a number of useful purposes for it.
Who are....THEY? The NSA?
Lazer is incorrect spelling.
Absolute beast I want it!!
They have the beam expander to remedy that. Styropyro uses the same diodes, all diodes have this it's just a matter of using the right lenses to elevate and direct the beam.
So I work in the defense industry. Missile defense systems and smart bombs. There is some public information on some "low powered" 5000 watt military lasers that can pin point the beam at miles away and burn holes through metal drone targets in just a few seconds.
So I'm wondering why the 7 watt laser couldn't have less beam spread at such short distances?
Wicked Lasers have 3 watt units that have very little beam spread at very long distances.
This 7 watt unit just seems like cheap Chinese manufacturing with low quality, only trying to squeeze out as much power as possible through this diode.
Nice looking machining on the housing though. Looks cool, kinda like a Jedi lightsaber.
but the laser you mentioned is invisible
imagine using that in Somalia 😥
whats it like at taking down speed cameras.
Well the cop wont be chasing anyone, because he will be screaming and fumblng trying to see with his newly burned out eyes.
8:40 you could blind 10 people at once with that lmao
Wow that’s got some serious power
7 watt? 7000 milliwatts?? Crazy
That laser is incredibly cool, but seriously, what can you actually do with it apart from playing?
MaximusPayne Vermin, ever hear of 3 blind mice?😝
Huh?
Use it to weld your Death Star?...lol
weather balloon + disco ball + 7w laser = epic happy fun time
It's great for setting sights on a sniper rifle.
WOW!!!! What an Incredibly Powerful, and dramatic, impressive looking device! Great review!!! I wonder how many accidental fires might result from careless use of such a tool?! GEEZ!!!! => BE CAREFUL out there!!!!
I have a survival laser S4X host that's ready to be used. My Nubm44-v2 laser diode came in today so I'm just waiting on my SXD 4.5A driver
that is not a laser, but a lightsaber
Do you need license in the USA to use and or buy them?
Here in Sweden, if they go over a certain "strength", a buyer would need a license..
Good video. A favor, I look so powerful, but infrared. Thank you
ha! i knew it was only a matter of time befroe the 26650 was used for laser pointers. i suggested it back in around 2009-10.
Nice calll...very cool! I remember 5watt lasers in the mid 90s costing 5k usd up to 10k! Those were he ne lasers. I built a .5mw in 7th grade that cost 500usd just for the laser tube!
