- I have some fluorescent lamps that look ordinary - but they are not! They are designed to simulate sunlight in a desert.
What makes them different and why were they designed like that? It is actually a dilemma of life. Let's explore it!

As a desert lizard stuck inside a room, I greatly appreciate these lights.
I am also a desert lizard stuck inside a room but unlike you I'm completely unable of conveying this fact, partly due to my lack of internet connectivity but mainly because I'm a lizard.
Lamps like these have been used to help children in arctic and sub-arctic regions as well. I found an article about it decades ago. There was a picture of a one room schoolhouse with a bunch of kids standing around a giant mercury lamp in nothing but their underclothes. It was apparently mandatory in some places to prevent bone issues.
Wouldnt it be more efficient to give them vitamin d supplements, or even fish liver oil like some nordic populations had done for ages? That way you wouldnt increase the risk for skin cancer and also will make sure enough vitamin will be in their bodies, especially since our skin is not that good on producing that.
@@mazocco Russian UV treatment. Logistics seems to be a problem in Russia, having a mercury lamp probably solved a lot of issues.
@@mazocco shipping several thousand vitamins vs 1 lightbulb. I should also point out there are psychological effects of UV exposure. They aren't well understood but seasonal depression from no sunlight is real. Lamp treatment helps.
@@mazocco This photo looked to be from the 30's or 40's. Vitamin D was only discovered in the 20's and synthesis for supplementation didn't occur until 1935. Meanwhile, the UV synthesis in food stuffs and animals was discovered in 1923. By the time supplements became widely available, the lamps were already well established, cheaper and easier to use. The practice continues in Siberia to this day and Ultraviolet Baths are apparently useful for certain skin conditions as well.
Lizards get horrible bone problems if they don’t get UVB.
You would love the UV lamps we make. 72” 46,800 watts. I’ve gotten sunburned from just a few seconds of light reflecting off of the floor.
Holy heck!
What are they used for!
Oh my, now I want one for blindingly bright fluorescence experiments :D Sounds seriously industrial, but I struggle to figure out what they are used for? Even for UV resin curing it seems a bit extreme?
@@brainiac75 my guess would be for air purification. we have a small UV light in our AC unit which supposedly "disinfects" the air after it's passed through the regular filter
Holy shit how many watts??
They are used in printing presses, lithium battery production, flooring, food packaging, medical plastics, curing automotive parts. Pretty much anything you need to have to go from a liquid to a solid almost instantly. Provided you have 480v 100amp 3 phase service for each.
9:04 I noticed the box states: "Unlike people, reptiles require UV-A rays to be able to perceive their surroundings effectively." I hadn't heard that before, but from what I can find it is true, at least for some reptiles.
Yeah, I read on the web that some reptiles can actually see UV-A.
Birds can too as well as many insects.
This is by the way why buz zappers use UV-A aka blacklight tubes to attract flies, wasps or mosquitoes to theit death.
Moths are ttracted to lights for the same reason: UV-A but also green and blue wavelengths in household lightbulbs.
Also their eyes will glow brightly under a Wood's lamp aka blacklight blue light like those used at parties.
Thanks for enLIGHTening us with the science everyone can understand!
You're welcome! Much more to come :)
@@brainiac75Hi, can you advice lamps of warm white light of sun spectre ? Like a old style bulbs but better ?
Used those bulbs for many years when I had a box turtle in an indoor enclosure. You needed to replace them every 6-9 months due to the UV output dropping over time. A proper UV bulb is required for most reptiles kept in indoor enclosures.
I use these to help plants get ready for outside after starting them indoors over winter and early spring. It helps avoid sunburn.❤
Did you have to protect your eyes from the light ?
I noticed one of the bulbs is an Arcadia bulb. A few years ago, Arcadia bulbs were difficult to find in the US. However, they are supposed to be much better quality reptile bulbs than other brands such as Repti-sun and Exo-terra. As a note, some rain forest reptiles also require these type of bulbs as well.
Once I worked next to a black light bulb for a few hours while I was purifying water for an experiment for my undergrad thesis. I got the worst sunburn of my life without even noticing it.
Was it actually a black colored tube, or was it a clear quartz tube (that appears blue)
@@bendito999 I checked online and it was a vintage Blak-Ray Longwave Ultraviolet Lamp B-100 A/R UVP. I saw a picture of one of them open and the bulb is mercury/quartz. This thing is serious it has an output of 100 watts full spectrum.
@@thecoffeeblog that's really cool! I have a 37 watt clear tube lamp that does the ~180nm UV that makes ozone, that I'd hate to be by for even a short period, 100w is serious!
@@1marcelfilms hopefully that turned out to be a lesson for you about wearing your PPE. The "welder's tan" is very real.
@@thecoffeeblogAccording to what I saw en eBay with the name it appears to be a UV-A lamp.
Longwave Ultraviolet also refers to that while Shortwave UV is another name for UV-C aka germicidal rays.
Getting a sunburn from UV-A alone is actually quite difficult, in fact I did the probably very stupid thing of trying to get a tan from a 400W mercury vapor blacklight bulb with a reflector and only got a slight tan on parts of my body that still had a bit of tan left from the last summer but no sunburn at all. (I protected my eyes with proper goggles that I got from a tanning salon though but that's only the eyes).
Sunburns typically happen from the summer sun's UV-B as well as from the UV-C coming off welding arcs and germicidal tubes.
Just for clarity the mercury vapor blacklight bulbs are made of black glass aka Wood's glass that filter out most of the visible light while letting UV-A rays out.
So it's also a Longwave Ultraviolet light and I'm really wondering how you got a sunburn from the Blak-Ray lamp.
The exposure to ultraviolet B (UVB) light is necessary for humans as it plays a crucial role in the production of vitamin D in the body. Vitamin D is essential for bone health and is involved in various functions such as calcium regulation and immune system health.
The primary source of vitamin D for humans is through cutaneous synthesis, which occurs when the skin is exposed to sunlight, particularly UVB radiation. When the skin is exposed to this radiation, an inactive form of vitamin D is converted into an active form that can be utilized by the body.
However, the recommended amount of UVB exposure may vary depending on factors such as geographic location, season, skin color, and sunscreen use. Generally, experts recommend exposing a significant area of the skin (such as arms, legs, and face) to the sun for about 10 to 30 minutes, two to three times a week, to obtain adequate vitamin D.
To ensure the presence of UVB, the shadows should be shorter than the height of the person. UVB radiation is most effective when the sun is at a certain angle in the sky. When the shadows are shorter than the height of a person, it indicates that the sun is high enough in the sky, allowing for a higher concentration of UVB rays to reach the skin.
It is important to note that excessive exposure to UVB radiation can increase the risk of sunburn, premature skin aging, and even skin cancer. Therefore, it is essential to find a balance between adequate exposure for vitamin D production and protecting the skin from sun damage.
In cases where sufficient sun exposure is not possible, obtaining vitamin D through diet or vitamin supplements may be necessary. Always consult a healthcare professional for specific guidance on the recommended amount of UVB exposure based on your location and individual circumstances.
Amen! I was hoping someone in the comments would say this. The importance of Vitamin D cannot be understated.
Sealing Molten sulfur in glass ampule creates a sulfur vapour inside making it glow a brilliant blue cyan near a Tesla coil, maybe you could test it out? I've got some pictures too
I have some noble gas discharge cylinders that I will make a video about. Unfortunately, I fried my first tesla coil at first power up (not my proudest moment...). The seller I bought the cylinders from also have some sulfur discharge tubes - will look into it! Thanks for the tip and early watch.
It said 'only for reptiles' in the beginning of the video. The title and your channel told me the entire story from that.
metal clips have another problem, it shortens the lifespan of the fluorescent lamp, if you notice with time of use where the clip is, it starts to turn black
Would it be a cooling effect that condenses the mercury and damages the phosphor there?
@@gblargg id guess capacitive coupling
@@H3wastooshort I see, could reduce the voltage, thus plasma.
Are these good for Lounge Lizards or will normal black lights and polyester leisure suits suffice?
For humanoid lizards I recommend UVA blacklights ;) Thanks for the early watch!
Went to college in a place where we don't see the sun for 6 months (clouds & snow). Therapists would commonly prescribe short tanning lamp treatment as a first step for depression treatment. Worked for a lot of people.
Given the choice between possible skin cancer and certain liver failure, most picked the former.
Hey, I’m a desert lizard stuck inside a home, and I feel great!
this reminds me of that one case, some years ago, where a club in china celebrated it's grand opening with a black light party, only lit with 60W UV-C tubes. they sure looked amazing, but...
Mine most dangerous light was one that hit my head after it fell from celling. I'm not sure how much uvb it had but I remember Lots of "F" after it hit my skin...
Thanks for this video! I hoped that you cover this topic with the UV-B lamps! I have heard that the UVB-content decreases over time and you have to replace the lamp after a year or so. People with no equipment but their eyes don't have a chance to see the "expiration" of the UVB part of these lamps. It still shines bright, though, in the rest of the spectrum.
Yes, the rule of thumb is to replace them every 6-12 months depending on the type and manufacturer. The cheap compact lights have shortest lifespan, tho newer T5 type lights from good manufacturers seems to have stable output even after 12 month, from what people with solarmeters tell.
I really love this channel… I remember the time when you where able to answer to every single comment XD
I’m really proud that I found this channel so many years ago
Brainiac in 2026: Testing some X-ray and transmitter vacuum tubes to see if they emit UVB.
Ngl it'd be a great project.
Я даже не знал, что рептилиям требуется особое освещение и для них даже делают специальные лампы. Спасибо за науку!
From google translate: "I did not even know that reptiles require special lighting and they even make special lamps for them. Thanks for the science!".
I know nothing about lighting or lazers or Denmark but these videos are amazing. Hypnotic and informative
That would be something that people in my region might purchase. I live in NW Washington state, USA. We have 9-10 months cloud cover, so we get insufficient sun exposure. We suffer from Seasonal Affective Disorder, get Multiple Sclerosis at a higher rate than others, etc. Our physicians often recommend that we take vit D supplements, fish oil, and other over the counter products to combat it.
This video is especially helpful for us! Thanks so much!
Personally, I would go for 'normal' light therapy lights + vit D supplement. Or at least a less aggressive version of these lamps like the ones for tropical climate (~6% UVB). The desert version is a bit too much in my opinion - but I would ask a doctor first :) Thanks for the early watch!
Sun exposure is often irrelevant when it comes to UV levels as the Ozone levels often fluctuate in the upper atmosphere, even air pollution can reduce the levels though there is a correlation with much higher levels when there is sunlight. You should always refer to you local weather forecasting station when checking for UV levels. UV is invisible in sight and touch. The warmth we feel from the sun is caused by infrared radiation.
Interestingly it seems like vitamin d alone isn't the only reason why uv light seems to reduce the likelihood of getting multiple sclerosis. It's kinda crazy that we still don't seem to know what exactly uv light does to our body.
@@nebulous962 Erm, we do know. While we do convert some of the UV into vitamin D. Long term exposure at higher levels is detrimental to the skin and carcinogenic.
Wow, I noticed a very low grid power there! Only 221.1V @ 49.98Hz? Is it always that low in Denmark? I've been to Denmark often, but never measured the outlet power.
I'm used to seeing 238V-242V @ 50.02Hz out of the wall..
It's a bit on the lower side. Just measured mine, it was actually 231,1 @49,98Hz but I believe we usually get 220 to 240V
Those are no single networks since decades, over (nearly) whole Europe it's one large power grid fuelling the then (more local to) local grids. It's said / calculated that all devices can run from 210 (or so) to 250V, too, because there were other voltages between the European countries, and the frequency has some tolerance, too. 50Hz means, it's a perfect match between all running electricity generating instances and all electricity consumption, so that the grid providers enable more regulating energy, if it falls under 50Hz and remove it, if it get's over. Thus all appliances can handle a range around 50Hz by design.
I have a UVB florescent for my lizard. The tank has a steel mesh that I cover with aluminum to maintain humidity - in only a few months, the UVB light burned hundreds of tiny holes through the aluminum in the pattern of the steel mesh. I gather that steel resists UV damage but aluminum does not!
For the TL/DW this is a review of a reptile lamp, as reptiles require exposure to UVB light to produce Vitamin D3.
Not only reptiles, we also require it, if not taking any supplements or fortified/exposed foods. Unless you eat a lot of fatty wild caught fish it is pretty difficult to get enough vitamin D from the diet.
@@Gengh13it's fine though as long as you go outside occasionally.
@@superslimanoniem4712 only if you are not that far from the equator and in the summer. In the winter there is a lot of atmosphere between the sun and the surface, that attenuates UVB significantly.
Cant wait to enjoy this video!
I like the work gloves for 10 seconds of UV exposure, a nice touch
Hehe, it's called editing - most clips are way longer than you see. Actually, June 2023 set a new record for hours with sunshine in June in Denmark! Didn't need the extra exposure to UVB from these lights :D Thanks for the early watch!
@@brainiac75 Did you walk around in full protective gear for all of it??
Thanks for enLIGHTening us with the science everyone can understand!. Thanks for enLIGHTening us with the science everyone can understand!.
Correct me if I'm wrong but uvb and uvc are largely blocked by regular glass, so when these lights are running in an enclosed terrarium they pose no danger to you
I used to think this too but the uvb light I have in my Lizard terrarium has made the paint on the wall behind the glass fade from the uv exposure. So I don't know what to think now
@@JoshPhoenix11 I think UVA can do this too and those lights give off plenty of that
@@batchampaSeems logical as sunlight shining through windows causes yellowing of white plastics as well as paint to fade in some cases as well.
In that case it can only be from UVA as UVB is supposed to be blocked by regular glass.
I was very happy 😃 when I got a new video notification 📢 from CZcams. Thanks for this video
i have been using those light and Mercury Vapor Bulb for more then 10 years for my reptiles
Thanks for the tan.
Really very nice, thank you for this interesting video! I am amazed and a bit surprised that the spectrum is so well printed on the box, except for the horrible colors... And I did not realize that reptiles need this kind of light. Good stuff!
You should talk to the reptiles more and ask questions ! 😎
@@pjeaton58🙃
Kinda tempting to get the lower output one for my room for the winter...
Thanks 👍
I actually have a lizard, and wondered about the spectrum of these bulbs. I guess if they weren’t accurate, a lot of people’s lizards would be sick and die. Mine is very healthy, BTW.
Thank you very nice❤
Это лампы для содержания рептилий, без таких ламп много животных из пустынных биомов плохо себя чувствуют, у них появляются проблемы с усваиваением кальция. Появляются болезни кожи, развивается рахит. Так же падает общий тонус и активность. 🤓
1:02 Lights, fixtures... now you need to buy some reptiles to go with the lights.
Thank you.😊
You're welcome 😊 More to come!
These bulbs could also be used in a plant growing tray I guess, but then again there are higher power UV lights available.
mark zuckerberg is buying those in bulk
Hey Brainiac, what kind of spectrometer do you use? I am looking to get one myself, as the cheap handheld one I have is, well, not accurate.
I'd like to ask something: if you use this lamp in a terrarium and it is in your house isn't that UV light bad for you or the terrarium glass will filter it?
Yes, the glass should filter UVB.
@@psirvent8 thanks
nice video. are you going to do UVC germicidal lamps next?
So I am a desert lizard... I clicked like. 🦎
oh this trube is made in Germany at 1:56 (might be Osram) ... 220V AC is a bit low for Denmark (see the "DKK"), it usually has 230V like Germany
Pro tip: don't wear shorts and a tee shirt in a room full of welders for very much related reasons
UV-C !
Also, don’t burn magnesium if you like your skin. 😂
@@5roundsrapid263I did that and didn't experience any adverse effects other than slight discomfort from the bright white light.
Didn't even give me eyestrain unlike blacklights for example as my eyes are apparently quite sensitive to artificial UV sources.
i may have bought something similar to get some uv radiation in winter cus it seems to help my mental and physical health. ofcourse i checked that it doesn't have uvc and also i keep the dosage low enough so that my skin don't burn oh and also i wear sunglasses when i use it.
Oh yes, the winters in Denmark can also be very long and dark... Light therapy is a real thing. My studio lights are a joy in the winter :) Thanks for the early watch!
@@brainiac75 you should see it in Iceland lol, sunrise at 11 sets at 15
@@brainiac75 truu but it's kinda uncommon to see people use uv light as light therapy. (Except that some people ofcourse use tanning beds)
@@KClO3 yeah it's kinda similar here in Finland too. 😀
@@KClO3 I really should go outside more and enjoy this crazy 24/7 sun we have..
This is honestly quite an interesting choice of light, but it makes sense for its intended purpose, though I do wonder if the risk of DNA mutation is worth it. I'm not an expert on the matter, though desert reptiles do sound like a challenge to keep healthy thanks to lights like these.
Great video as always!
Yeah, I'm a tropical fresh water aquarium guy so desert reptiles are beyond my expertise too :) Thanks for watching as always!
How would be the risk of mutation not worth it? I mean, as glass (windows and glass terrariums) blocks UV-B they won't get ANY UV-B in captivity (wihtout which they get metabollic bone diesease). We use those light to give them the amount of UV-B as they get in nature. The risk of mutation isn't any higher than in nature. Also it's not only desert reptiles. All day reptiles need UV-B, just the desert species need more of it.
If diurnal desert reptiles risked dangerous levels of DNA mutation from exposure to the desert sun there wouldn't be any left.
I use a similar type uvb florescent bulb in a handheld medical unit to treat psoriasis with uvb light therapy in short exposures every 2 days can burn very quickly
If "only for reptiles" is not enough evidence that it is ONLY for reptiles, I don't know how else it could be noted...
Looks like a good bump around 405...wonder if these would be good for curing resin
Nice Video! :-)
Glad you like it. More to come, Pyro!
What's the spectrum of an old, off-the shelf CCFL? How does the spectrum of a new one compare to that of an old one?
In general, fluorescent bulbs all produce the same spectrum, it just changes color based on the phosphor used.
Check the spectrum of some of those super cheap red light therapy led panels
you can power the bulbs from a high voltage source directly.
Which spectrometer do you use - please?
I use lights like these. Some reptiles absolutely need UVB, to prevent MBD (metabolic bone disease) as they use it to process calcium and get even get diseases if the Vitamin D isnt included in their diet or from the lamps, sometimes both. It has to do with their first pass metabolism among other things. I have them for my Leopard Geckos and as an extra thing (it also keeps mold away in a humid terrarium lol) for my snakes, which eat whole prey, contributing to them not needing it. Keep in mind in reference to animals the sun is much further away, and the various animals environment may normally filter the light specifically depending on location - less so in arid or desert environments, moreso in the tropical, subtropical or other environments which indicate use of 5.0 bulbs. Theres Mercury vapor bulbs that also provide heat and UVB in one bulb, various companies and methods etc that have varying quality - tho UVB is really what matters most, with UVA and such being helpful too (tho various species and even overall, its widely debated at least regarding specifics)
If the spectrum meter shows UV wavelengths then why does the lamp display white light?
Because it has been designed to output white light as well as UV-A and UV-B.
It's the phosphor coating inside of the tube that defines that.
Bug zapper tubes on the other hand come with phosphors that output more UV-A than what the mercury discharge itself can produce and they also let the blue light out as well.
i'm a house plant not a desert lizard but close enough.
If you could spare the excess electricity cost, it would be very interesting if you could investigate the claims that these lamps need to be replaced before they visibly stop working, because of the degradation of the UV emission. If you could set one up on a timer to run for 12-16 hours every day for 6 months and then re-measure the spectrum, it could let the amateur reptile keepers among us know whether they really need to buy a new one every 6-9 months like the manufacturers (and internet) claim.
*licks eyeballs*
You revealed the answer at 1:34 for those not already aware of these. It states it on the tube.
Both UVA & UVB can cause DNA damage. A=Aging & B=Burn. Thank you for your video and information.
Yes, that's totally me, a crazy wizard stuck at home. Like from me.
What protection did you use? From general understanding, Cotton and even polyester aren't great protectors of UV. Did you just slap thick layers of sunscreen to protect yourself when you recorded this video?
4:40, made it to low mun orbit, preparing for landing burn in T-00,00,02,00.000
Do you maybe have a friends that is a Tig welder. I would love to se the spectrum of a TIG arc.
What does the 75 mean in your channel name?
My first name and birth year are 'hidden' in the channel name ;) Thanks for the early watch!
@@brainiac75 Brian?
What spectrometer do you use?
Favourite lights of Mark Zuckerberg
I guess some marketing guy cut off the black "borders" (UV-C / IR) of the spectrum leading to the shift.
Seems likely but removes the point of including the spectrums ;) Thanks for the early watch!
Noticed it said for reptiles only
The kelvin ratings don't make sense. Why is the light bluer and colder when it's rating is higher? Normally higher kelvin means the light gets more yellow. Or am I missing something?
Lower Kelvin = more red = longer wavelength
Higher Kelvin = more blue = shorter wavelength
It's the opposite, with higher kelvin being bluer and colder.
For example overcast sky daylight is over 10 000 kelvin while a halogen bulb is about 3000 and a incandescent bulb 2700.
You see that's the dumb thing
Higher Kelvin would mean hotter
@@emocan126Actually it is but it also gives bluer light the hotter it is.

UVB isn't what's DNA mutating. DNA mutation is only possible from 285 nm and lower wavelengths. Potassium gets ionized at those levels.
As a lizard person, I approve this video.

Why the thick orange gloves?
To protect his skin from UV-B sunburns.
@@psirvent8
Are you sure? Why use the south pole edition then?
@@Peter_Riis_DK Well, UV-B will cause sunburns if you get too much exposure especially from a powerful source at close range and the thick gloves are there to shield the hands from those strong damaging rays.
The color of the gloves doesn't really matter as long as they are thick enough to block all the light coming from the bulb.
@@psirvent8
Never mind.

I need too buy a wide range spectrometer
Do "Sun" LED lamps work? Which is the best emulator of the real Sun?
I doubt any LED will be a good emulator of the real Sun. Unless they mix different types of LED (UV etc.). A high-wattage halogen lamp with a UVC filter - but no UVB-UVA filter such as soda-lime glass - is probably the closest emulator. Thanks for the early watch!
@@brainiac75 Thanks for your video and your reply. Is Soda-lime glass the same as Pyrex brand?
@@brainiac75 Also, does old fashion filament bulbs produce light close to the wavelength of the Sun? They tell me I need a Sun lamp for my SAD condition.
@@piconano borosilicate glass is the one with low thermal expansion…used in original Pyrex kitchen ware. The soda lime glass is more typical of window glass and glass bottles.
@@UppsalaSal Makes sense. Thanks.
it says only for reptiles
Plastic holders will no last long because of UV.
They will yellow and turn brittle just like plastic stuff left outside during summer I guess.
True but, some Aluminum tape will fix that. (Just, keep in mind the tape is electrically conductive. Keep it away from the bulb's contacts)
Does this mean that we are exposed to UV-B radiation under the sun?
Yes.
@@psirvent8 GOOD.
@@bmaj55Well, too much exposure causes sunburns nevertheless.
It didn't specify that it was a desert in our solar system
Maybe someone else bought those cheap UV-B tubes for a solarium, with human users 😬
Actual tanning tubes also emit UV-B although it might be less than reptile lamps.
I tried to get a tan from a 400W mercury vapor blacklight bulb with a reflector, however it didn't really work and I think it might be because it doesn't have any UV-B in its spectrum, only UV-A (Since it's enough to make fluorescent things glow at parties without causing sunburns to people).
I am an American, and I haven't heard alot of different versions of the English accents but your voice sounds identical to King Diamond, Thanks
Sun-tanning Lamp ?
When the ex wife takes the house so you replace all the lights with these things
Think about the light that would wipe the planet out if not for our atmosphere or magnetic field.
they say "desert", maybe it's just on another planet xD
