In this video I show how to turn your phone light or other LED lights into a makeshift UV light.
Sadly it's not as powerful as a regular UV seeing as all we're doing is filtering out the visible light, and not actually generating any more UV. But it's strong enough to at least have some fun with. And can make a cool party trick!!
This is not my own original Idea, I was shown it by a friend whom had learned it from someone else, just to clarify... Though I believe I'm the first to try Incandescent lights.
Anyways thanks for watching!!

I was honestly expecting a troll or a rickroll. But it worked and I got an explanation too! Thanks OP!
+Prestige Wookie No problem man glad you liked it!
Too notch quality video, really
Keep up the great work.
Chasebeaste Thanks :)
Thank you so much for making this dude!
No problem, and thank you so much for watching it :)
Awesome video, man! Keep it up!
One person found stains on their hotel sheets.
ArgentOrangeOK XD it took a week but I just now got your Joke. XD
My RGB-LED strip has the same effect when it's set to blue.
Nice video ;)
+Iason Kourouklis Thank you, and yeah I have had RGB's behave similarly during specific colors too.
Thanks, im definitely gona try this out:)
Dennis wångberg Good luck!
Thanks bro! what feltpen need to use? ( markers ) normal school feltpen isnt right choice huh?
So awesome!
Very very cool. I hope to try this soon with my nieces
I hope they like it: )
GOOD IDEA KEEP UP GOOD LUCK YOUR GOOD THINKING
Well thank you friend.
That's so cool I used light blue but it still worked
Brandon Weber Good to know!
Huh... I was think why is it called a black light and I know that black markers are made with layered blue ink (also purple sometimes, you can see this if you smudge the ink with a wet napkin) so I guess the same principle of using blue and purple to make "black" is in effect! Also Techno Castle! XD
I want ask you, when you use e.g. blue colour filter or other colour filter, will pass through only wavelength of that colour? Or through filter will pass everything above that given wavelength?
Here, this page actually will show you what effect almost any color filter will have on the light spectrum.

TrollFaceTheMan Thanks. But I have one more quetion, is there any filter through that will pass only unvisible UV light, and nothing more (I mean you wont see any blue or other color).
www.amazon.com/Baader-Planetarium-U-Filter-Venus-Ultraviolet/dp/B0018IWQJ6
This filter is supposed to block all but invisible UV light, with the exception of small IR leaks that can be fixed by coupling with an IR filter.
I've been wondering if someone could simply take a high-powered flashlight and put a optical UV filter lens on it like you would use for a camera. The lenses are cheap and I've been wanting to try it but was hoping to see someone with a similar idea before doing it myself. They sell 365 NM optical lenses a lot of places I just don't know if it will work when a light is shined through it rather than filtering a camera.
That's a handy tip for finding genuine uranium glass items in an antique shop.
Green Silver Interesting point, I wonder how well it shows up under this makeshift Uv...
Sweet!
Carlapillar Like candy!
Hi trollface. thanks a lot. V.nice video. I would like to ask that can we see human aura thru UV light.
Pls. answer.

Can this harden the uv resin ??
I saw this and thought it was fake and was a scam or something
Then I saw the comments and thought it was definitely a scam
But damn, nice video
But it's not fake, what comments are you talking about it 100% works..?
It looks like UV FUM instead of UV FUN after you put the wavy circle around it
cool
Thanks
Nice way to make a uv light. Do you know where I can get a very strong one, for urine detection, in daylight, on carpet? Must be strong. :)
Buy or DIY?
@@TrollFaceTheMan Buy
@@patrickyanello6015, do you have an idea price range and are you looking for something portable like a flashlight or something plug in work?
@@TrollFaceTheMan like a flashlight, but some of the ones I've seen online that are supposed to be powrful in daylight are anywhere from over $200 down to about 159.
@@patrickyanello6015, how much are you looking to spend though?
did it need that marker you use, or you can use all marker?
if it's only can with that marker, can you tell me the marker's brand?
+Computer Gaming (TheCompGaming) Any "Permanent Markers" can be used (As in the ones that don't Rub/Wash off) but they have to be Blue and Purple. The brand I use in specific is know as "Sharpie."
where i find purple and dark blue marker? im from indonesia
I got mine from a Supermart called Meijer, but most places that carry school supplies I'd imagine have it.
ok
just here cos ima legit check my yeezys lol
Does it work on uv resins? Would it be strong enough? To cure things?
If the regular light shines on the resins can't cure it then this sadly won't either. Remember that we are not making UV light here. Simply filtering out the other light so you can see the UV or near UV already in it.
wow thanks a lot
No problem, glad you liked it :)
can i see my sunscreen color with this?
Typically you can only see sunscreens effectiveness with a very specialized UV camera.
so your phone is producing uv but the tape filters it so technically your phones torch is the cleanest place on your phone.
+banana gaming the problem with that though is it produces very little UV-c which is what destroyes DNA and kills bacteria.
The phone light mainly is going to produce near uv and a tad bit of UV-a which for the most part is harmless to bacteria.
so the phosphorus changes the uv wavelength? What about infra red?
mamupelu565 As in does it affect infrared..?
+TrollFaceTheMan I think if you add a layer of yellow and then a layer of green it will be all infrared light
I only have started researching light spectrums lately so do you mind me asking you reasoning behind that?
TrollFaceTheMan I think it would work like that because adding those layers would block those other wavelengths of visible light... Not sure
Can i use this for my Turtle?🐢
+Heyman's Little BeasT Maybe depends if he glows under UV normally.
Does it have to be perminant marker
+VWzachyBOY Plays I haven't tried with other markers, but so long as they are similar color and can coat the tape well it still theoretically should work.
Nice memes meme boy
This can't harm you can it like the natural ultra violet light
Thanks
You are probably thinking of UVB and UVC both of which come from the sun, though UVC is basically all filtered out by the atmosphere but both of those can be quite nasty.
This light will mainly have UVA and Near UV which is basically harmless unless you shine it into your eyes for awhile. Remember we are not creating any new light here, we are simply filtering out non UV light. So this filter makes it no more harmful than the original unfiltered light coming strait from the LED.
Lol do you think normal blue & purple markers would work with this
Theoretically if they are the same color then they should, yes.
Will it work on scorpions
+Snake Lover It might if they normally glow under UV lights.
+TrollFaceTheMan thanks

Hello~ may I ask you a question? But I would want it to be more private, so would you send me a direct message?
I don't believe RUclips have the ability to private message any more.
Can someone invent some glasses that can make us see all the spectrums? :/
Damien Mohammed Cameras can do it, if the have the filters removed.
will it see bcterias?
+Rg Curry Maybe, but I think you typically need something else to actually make them light up.
I'm going to need to try this with some tonic water.
atomicsteameng I will be definitely curious as too how well it works, if you do do it please comment your results.
This is just a light with color
That is actually highly incorrect, there is no color added to the light Only color removed...
No like I mean a tint your shining light through color making it have a tint
Also thanks for replying!! you have so many subs no one ever replies to me with lots of subs
Yeah no problem I try to reply when I can, but what is happening is the tape is filtering out other spectrum of light and leaving only UV and Purple/Blue behind..
Basically white light is actually a rainbow with red, orange, yellow, green, blue, indigo, and violet. What the colored tape is removing is all Colors but Blue, Indigo and Violet.
So it filters the light, not tints it. That was what I was trying to imply.
Oh ok
This do
like you to tell the truth
?
This is just coloring your light
That is not how light works. If you understand even basic light physics or phototheory you'd know that.
Sadly I dont
Also this is a 4 year old video and you still respond to comments?
@@raccoonperson8895, I try to yes. Basically light isn't colored only filtered. (There are exceptions like with phosphorescents but that doesn't apply here.)
If you pass a white light through a red filter the white light appears to change red but what's actually happening is all other colors that are making up the white light Excluding the red are being absorbed or reflected. The red light you see pass through the filter was always there, not created. As such if you tried to pass pure blue light through that pure red filter nothing would come through as there is no passable spectra.
Same here, we are not making any UV light or coloring the light. We are filtering out other Colors of light to make the UV light usable. The UV light is always there, just not super strong.
it is fake! uv light is much different!
I can assure you this most defiantly is not fake. Once again this is a light filter that removes all but Uv & Near Uv spectrum from LED's emitted light.
And another thing is if it was fake wouldn't you think that out of over 25,000 views I'd have more than 8 dislikes and a lot less than 175 likes..?
Please referance this chart to see that Led's do in fact produce light in the 390-400nm range which is UV spectrum and will light out UV reactive objects.
www.gl-leds.com/led-bulbs/img/b60-led-bulb-spectrum.jpg
+TrollFaceTheMan fluorescent markers light up because they react with blue colour.
just try your modified flashlight on tonic water or a money to see if it works.
Once again, LED's produce 390-400nm which is still UV. You filter out the other colors and you are left with a week UV light. Also do you have a source to your claim that the markers react with blue light?
+TrollFaceTheMan ok. why is uv light also called blacklight? because it is very visible to naked eye? i don't think. this purple color looks like UV but it isn't. just try to verify a legit money with phone flashlight and tell me if it works.
cool
Thanks!
