I've always wanted to make a high-powered flashlight. In this design, the light source is a 30W LED, powered by 3 li-ion cells. / mn.projects / maciej-nowak-962547184
Thanks for such positive comments! Answering the questions: The battery lasts about 45-50 minutes at 100%, and about 2 hours at 50% (probably the electronics have higher efficiency with less current). The charging time is about 8 hours (the controller limits the charging current to not overload the USB charger). As for the thermal protection, the controller has a negative temperature coefficient (the current is reduced as the temperature rises). However, it was not needed, the housing is large enough to cool the LEDs without any problems. I think I could even apply more power
Li ion batteries can be easily charged with a current of 0.5c. And this is for any capacity 2 hours. It is enough to install a 5.5 or 5.2 connector there and charge it with a charger from a laptop, or any other 12-13v .. If the controller limits the current, then it is better to replace it, since there are a lot of them on aliexpress. I also wanted to make a powerful flashlight, but I ran into a problem in finding an LED, many well-known brands of flashlights have small but powerful diodes, and large and low-efficiency assemblies are on sale .. I wanted to do something like yours, but with an adjustable focus and lens, with a power of about 50w on the assembly 3s 5200mAh from a quadcopter, they give a high current and quickly charge, and with such a size of the case, 50w will cool quietly .. And what would certainly be possible to make the cooling fins of an even larger area, taking a cutter 1mm thick and making grooves 1mm apart ..
Excellent ! Very nice job without unnecessary things. What I miss in stock production and you did here is separation of switches for mode selection and on-off. Well thought project, congrats !

@@joshfoley8862 Knurling is certainly good .. but it’s cold to hold on to the metal .. and with gloves, it’s not going to slip out of your hands at all.
Dude, you're doing great things! I really like this flashlight, if I could find the ready-made electrical components, I would make one too. Beautiful video! keep it like this 👍🏼❤️
Besides the result, the best part is that nothing is glued to death, even the cells are covered with tape, could disassemble everything anytime, wouldn't make sense but it would be possible. Great work 👍
Great job! This looks like it is super bright! The forest footage in the video reminds me of some of the paranormal investigations I've seen on youtube of so called haunted forests and such.
Beautiful design and really nice build quality! I love the design. Nothing wrong with good quality cob leds..... but if you do a bit of research and poke around ......look at some of the Cree XHP LEDs… Like the ones used in the convoy L6 and M3… I think you’ll be amazed at what you could do if you grouped a few of those together in a light like this. Wonderful craftsmanship! Keep it up!
"When you need to see something on the moon". I frickin' loved this, great vid. I also found myself chanting, "Anodize! Anodize! Anodize!" as soon as you made the first section :)
That's a beauty. Made from almost scratch from the barest parts, and so solid too. Loved the use of screws to fasten the parts, that's gotta be one solid package. I get that it's not a commercial product, only a toy made for fun, but if only it had any waterproofing and like a 5 or 10% mode, I'd want one of those. 🤩
Nominal voltage for a 3 cell lithium battery is 11.1v. To produce 30w of power takes 2.7 amps at that voltage. The cells he used were 3500mA/h, which if 100% efficient would give 1h17min, but realistically it'll be more like 1h due to wasted power in both the driver and step up converter. Lithium cells last a lot longer if you don't fully discharge so limiting it to 45min would be best. I think he should have doubled the number of cells, and instead of 50% have low power be more like 10-20% as it's still way brighter than you need for most situations. Still a great build though.
@@mihanovak2228 nah it’s not. And don’t pretend you could‘ve explained it this flawlessly! No need for spewing defamation just because someone else was better than you...
@@JPEight It is enough to install good batteries there and not worry about their resource, they are not so expensive, and it is not so difficult to replace them, 6 batteries in that case would not fit, but a ready-made battery for radio models would fit in there. Rights they are expensive, from - for the given current in 25c. And here this is not necessary ..
You are right about batteries being not that expensive, but I’d still rather they didn’t need replacing regularly. Obviously there’s not enough room for 6 but nobody forced him to use that length tube...
What a great flashlight. From an engineering point of view, it contained so many disciplines: lathe, pcb design and manufacture, choosing support components, CAD, system-level design, and so on. Great flashlight. What did the finished product weigh?

It doesn't over heat at full power?
Wonderful job can you make one torch for me
Can u sell this Torch and Wat price u can sell??

This is the best make of video about this type of light on CZcams. I saw many many yt DIY videos, but this is surprise for me how great this is.
Really liked, with all these equipments one can do anything. Beautiful, neat and clean work.
Excellent ! Very nice job without unnecessary things. What I miss in stock production and you did here is separation of switches for mode selection and on-off. Well thought project, congrats !
The pleasure of seeing something you've made working well.
Nice job.
That's the coolest diy flashlight I've ever seen. Good job dude!
Beautiful work. It would be really cool with rubber grip tape too. Love this. I've spent more money than I care to admit on flashlights. Great build
Wow MN you’ve outdone yourself. Mechanical and electrical build. And very well made. I’m impressed and inspired
I love seeing smart people in action.
As flashlight reviewer this is pretty cool, It makes me want a lathe.
Loved the way you use glass from watchmaking side,
Sometimes such attention to details make perfect match 👍👍👍
It’s an amazing and successful project! Excellent score!
Truly a work of art, that works... Nice clean look. Great job
You just blew my mind with that board you just made BY hand I’m not to electronics.. but that’s an instant subscribe. NICE

Professional work..well done
Beautifully made. A good design is so pleasing😁
IT'S A BEAUTIFUL WORK! Very well done and "clean". I saw a person who works perfectly!
Solid and rugged look awesome job 👍
Beautiful work. Might need a little "texture" on the tube for traction?
Knurling!
@@joshfoley8862 was thinking the exact same thing
A tennis handle wrap would look good on it (I think). 😅

Absolutely amazing.
PROJETO ESPETACULAR !!! PARABÉNS !!!
Suuuuuuper Work. Fantastic. The best Torch ever seen.
I am totally blown away on your video amazing to have such great talent to build something like this you're truly awesome
What an amazing skill you have man!!!!
You are extremely talented plus you have a nicely equipped workshop. Love it my friend 👌👌😊
This is a real cool light. Look forward to make myself one. Thanks
Kindly let me have one.i will pay cast.
Love the build man!

Why dont you just search for what he mentioned on eBay?
Nice craftsmanship- a work of art! Why anyone would give this a thumbs down is beyond me.
Fantastic, great work with precision

Very nice looking light you are a true craftsman great skills my man
Naprawdę kawał dobrej roboty 😃
That flashlight looks like a light saber!
Priceless!
बहुत जबरदस्त टोर्च बनाया है
लोग सिर्फ देख सकते हैं खरीद नहीं सकते
कियोंके आप सिर्फ अपने लिए बनाया है
Some sealing can improve the product.
Fantastic powerful flashlight you build 👍
Impressive piece of art and engineering. Well done
nice! beautifuly crafted 👍
Absolutely superb!!
That is a very nice job. I would like to see if you can make one where the beam can be adjustable
One of the best torch 🔦, keep it up
Bro.... fantastic project, I like the non-standard design and build. Friggin impressed, and that's saying ALOT!
Wow that is a thing of beauty! Id love to have a go at a flashlight but it’d be pants compared to this. Brill video.
Ficou muito top, apenas faltou vedação contra água, parabéns pelo vídeo.
amazing....a very nice job.
It became a beautiful lantern. I definitely need a tool for camping. Health to your hands master ...👌👍👏🙌🙂
Holy smokes that thing is bright. 😳👍🏻
Woww...
That is so cool.. Also really bright.
Ooh marvellous, nice job and good instrument for darkness.....
Sweet design
That is truly a work of art. I am impressed. If you ever want to sell it I will buy it! Make sure to etch your signature on it.
Wow, that's impressive.
The driver look like entirely passive with no dedicated IC? Can we have the schemarics for other projects? It migth fit a flood light project of mine
Great product. Well done.
Brilliant, superb, outstanding 👌
Keep it up 👍
I Love it Dude it looks perrrfect! 😃👍
Beautiful and professional !!
Great Job, well Done!
Excelente trabajo. Saludos desde argentina
Super gemacht!
Nice professional project.

From full charge how long does the battery last at half power and at full power?
Nominal voltage for a 3 cell lithium battery is 11.1v. To produce 30w of power takes 2.7 amps at that voltage. The cells he used were 3500mA/h, which if 100% efficient would give 1h17min, but realistically it'll be more like 1h due to wasted power in both the driver and step up converter.
