Channel really helped. I’d recommend looking into UV golf ball hunting and what lights are best. I know 365nm would be best, but putting a video specifically on that might increase traffic. I searched with a 395nm UVBeast, but it was hard with so much light bleed. I just ordered a 365nm one to better see the hidden golf balls.

[@UVBlackLights]

I'm glad I can help! Do all golf balls react to UV? I'm assuming the fluorescent looking ones do, like chartreuse, orange and pink. I guess I can test them with my white ones that I have laying around somewhere. I'll do some research on UV golf ball hunting on here, to get an idea. Thanks for the tip!

[@CaptFalcio]

Hi there! Good stuff in your channel. This picked my curiosity. Last year I made a phosphorescent (not flourescent) mural and charging it with a 395nm light seems to yeld good results. Now, not having the issue of what becomes visible and not and being focused only on making the strontium paint glow as bright as possible (and charging it as fast as possible), I'd wonder if you'd still recommed a 365nm light for it or if in my case stronger is just better. Actually had the idea of going with a UV-C lamp for room disinfection when no one is inside, but I guess it would do a poor job for what I have in mind?

[@UVBlackLights]

If you're just charging the strontium paint both 365nm and 395nm will get the job done. UV-C should charge it as well, I'm not sure how long it'll hold the charge since I don't really play around with UV-C. In the end if you just want to charge it as fast as possible any UV light source will get the job done. Hope that helps! Thank you for watching!!

Trying to get something for fog lights on my car. Recommendations for wavelength and where to buy the diodes?

[@randyrhodes5909]

Great video! I am working on a ceiling mural and made the HUGE mistake of purchasing the LED black light, which is terrible if you are recreating a realistic scene. I'm painting a true to life night sky with full moon and some light clouds and tested the LED black light and everything is washed out with pink and purple. So I decided to try to find fluorescent, which is and always will be the best...and discovered that very few folks are making them or selling them. That's a real shame. Nothing beats a fluorescent black light, ever. Great video explaining the difference! I'm glad I didn't by all ten of the crappy LED's!

[@UVBlackLights]

Yes, most LED blacklight is trash. The only 365nm LED I know of is from Wildfire Lighting. They always have the true UV. Appreciate the kind words and thank you for watching!!

[@our1980shouse]

Hi! We're in the process of redoing a house built in the late 70s. I'm planning to decorate a closet with floor to ceiling blacklight posters. It's not bir, probably about 4 ft x 4 ft with 8 foot ceilings. Any suggestions for what type of light I should use? Thanks!

[@UVBlackLights]

Hello! Screw In type bulb should work, you don’t need anything big. Personally I like the 365nm wavelength.

[@dhawthorne1634]

You don't need black light for florescent materials to work. So long as the light is of a longer wavelength than the light that the material will emit, they will fluoresce. The further into the visible spectrum, the dimmer the emitted light will be and the visible light that can reflect off nearby objects will make it's perception harder, but it still works. You can also go beyond UV. A low wattage x-ray source will emit NO visible light, very little UV light and the florescence will be incredibly bright. The x-rays will break down any phosphors with time and it's really hard to rave in a 2 inch thick, lead lined body suit, which is why we stick with UV technology.

[@idanksinatra416]

Hey so I’m looking to light up a big inside area with the 365 look, but already hung up a TON of the more visible uv leds, I would love to be able to transition those to have less visible light, and would like to paint them or diy a band pass filter, is that possible?

[@UVBlackLights]

Band pass filter will block out some visible light, but the cost on getting something custom made like that would probably cost alot. Might be worth it to just buy 365nm blacklights.

[@jopoli88]

Hello! Thanks so much for your content. I am working on an art piece and the paint I'm wanting to use is the invisible paint. I saw based on your other vids, I should be using the 365nm lights. Do you think the 400 would be better for the invisible paint or should I stick to the 365? Thanks!

[@UVBlackLights]

If you’re using invisible paint, you want to use 365nm only or some of the colors won’t work.

[@staciemeyer9152]

I'd like to get a UV flashlight to play with in the desert around my house. The desert is full of fluorescent minerals and scorpions but also non-fluorescent cactus and rattle snakes. I am wondering if a light with a bit more visible light (400 nm) would work better for me than one which isn't going to light up snakes and cactus and other things that I may stumble on, anyway. I have exactly zero experience with UV lights. Any suggestions?

[@UVBlackLights]

@Matt Rivers if you’re looking for more visible light then yes go with the 400nm. Although you can’t go wrong with either, because the 365nm will still put out some visible light. I would look into the UV Beast Flashlight. I have 2 videos on a 365nm and 385nm. It’s pretty powerful and has a little bit bigger beam spread than those smaller hand size UV flashlights. Hope that helps!

[@gregistopal]

365 would be better though because 365 lights up the most florecent material

[@michaelwhite613]

Duuude! You had me totally nerding out haha this is awesome content! I was looking at black lights for night fishing on the beach in SoCal when I stumbled across your channel. I thought they were all the same. lol I ordered a couple to try but now I’m diving deeper into this after this video and will most likely end up upgrading these soon lol Thank you

Yeah it’s pretty crazy how different blacklights are. You can’t just buy one and think it’s good enough.

[@openyuheyeby8674]

Looking for a blacklight flashlight to detect a florescent dye I put into A/C copper lines to find a leak. I'm about to purchase 390 to 400 nm. Was wondering if this is fine for the application

Yes, that’ll work but I would use 365nm when trying to detect anything.

[@magicalKhachapuri]

I wan't to see the painting done with the uv reactive dye and I would like your advice about which nm would suite me best, I kinda would love to have some purple visible light. Thanks

[@UVBlackLights]

@gurulee Which painting? Normally you wouldn't use the UV Water Dye for a painting application, or do you mean UV Paint, not dye? If you want the Purple visible light then use anything in the 385-400nm wavelength range.

I want to make a display case of glow in the dark funko pops. Do you recommend 365nm or 395nm

[@UVBlackLights]

Strongly recommend 365nm. As I have a few funko pops and the 395nm distorts the true fluorescing ability the pops have.

Hey man, ive just started a little section in my room setup with dj decks and it has a slanted ceiling either side of it coming to a point and ive painted it black. Im putting posters and tapestries all over it and the wall behind it too but im not sure which light to get? Whats the safest for a bedroom and for exposure to eyes cause theres no real way to avoid it with the setup. Would it be best to line the ceiling in 5m 395 - 405 LED uv strip or use a globe or install a fluorescent?. Any ideas u have for me would be great. Also any safety options as i have a dog too :) cheers brother love ur videos.

[@UVBlackLights]

@Jordan raiola UV strip would be good if you’re limited with mounting options for a fixture. I’m guessing the posters have no invisible dyes in them, so you can go with 365nm or 400nm. Just keep in mind 385-400nm you’ll have the purple visible light. As for safety, just don’t stare into them and make sure they’re atleast 4-6’ away from you. If you need eye protection, search for some UV protection glasses. Hope this helps, if you have any other questions, let me know!

[@anyTimeTV24X7]

Hi, can you please reccomend me which UV light to use for observing UV ink on banknotes. also i want to film and take pics of them so which light would be the best??

[@UVBlackLights]

Any cash, bank notes, passports, licenses definitely want 365nm.

[@hatemadness]

I'm looking at this for I'd checking. I have a 385-395 uv flashlight. I looked at the state of California's dmv website. It showed some makings on the id's but not all. Specifically the green golden gate bridge. I wonder if it's my flashlight. Are there certain wavelengths that certain nm can highlight and others that can't? Would 365 be better for an id like that ,?

[@UVBlackLights]

@hatemadness yes, you definitely want 365nm UV flashlight for that. Certain colors only show up under that wavelength.

[@ShinigamiUchihax2]

*Please reply* I work doing (NDT) non destructive testing and in order to perform certain operations I use UV lights around 265-345nm, I add fluorescent penetrant on the parts I’m inspecting and proceed to wash/rinse them under the UV lights. I usually spend about 6-8 hours daily doing this. Can this exposure be harmful to me? My face is literally exposed, I mostly get my hands exposed even though I do wear PPE gloves etc… Recently I started experiencing itchiness and a tingly feeling in my hands and forearms the two areas I get exposed to the most.

[@UVBlackLights]

YES! Long and close exposure to UV light is very dangerous, especially in that lower wavelength.

[@samtorland128]

Hi Great review by the way. I need advice on which is better for indoor football with uv light, football in the dark?

Yo, I would like vibrant neon colours in background but to have enough light to record myself and be seen. Separate lighting? Or would it interfere?

Any other lighting will diminish the black light effect, so for your other lighting you’re going to want it as dim as possible. Unless your background is far back enough in a darkish area.

I've got a small 1bedroom apartment that I'd like to deck out with blacklights. but I'm not sure whether to get the fluorescent tube lights I had as a kid or whether to go the led route which may not only be cheaper but also brighter as well. You didnt touch on fluorescent tube bulbs however I figure you'd probably know which would be better money wise as well as brightness... I'm also wondering how many I will need to buy in order to make my apartment really stand out. I know if I use tube bulbs I'd have to buy 4or5 24in bulbs just for my livingroom. Would it be cheaper and turn out better if I use leds rather than the tubes? I pay 10$ for a 24in fluorescent tube @Walmart... If you have the time to respond I'd really appreciate you're input...

[@UVBlackLights]

Check out this video it may help. Fluorescent vs LED. kzbin.info/www/bejne/rpq5o6ODg8qSqtk You really can’t go wrong with fluorescent or LED. You probably only need 2 blacklights per room, if that’s the only lights on and it’s pitch dark. Although if you’re buying cheap ones from Walmart then yes you’ll probably need a lot more. I would invest and pay a little more for quality, you won’t regret it.

I would try to get 365nm to reduce as much purple visible light possible, but it can get very expensive versus 390-400nm led diodes. Also be very careful on how close of contact you are with these UV diodes near your skin and eyes.

Hey I have a question regarding the power (Watts ) of black light, which Option I choose to be able to cover 10 feet x 10 feet room (I know it is small) really everything glowing with no visible light? I want to have these black light for party application and use it with my Party light together, I want when the party lights get off, everywhere get's completely dark except the glowing parts Many people said these low watt blacklights are useless, because you should really close it to the target to glow, I want install something on the wall the whole party and make sure it will cover my 10 feet x 10 feet room, you say the stronger watt of blacklight (let's assume 365nm) is also means higher visible light, so what is your suggestion? completely darkness except strong glowing effect for a small room 10feet x 10 feet and fix position for black light,

[@UVBlackLights]

Well every blacklight has some visible light, unfortunately you can’t make the room pitch dark and have the posters glow. With that said, you want a 365nm blacklight so it’ll have less visible light than a 390-400nm blacklight. Please check out my “Best blacklight for room video”. That might steer you in the right direction. Let me know if you have any other questions. Thank you!

[@ikamy]

@@UVBlackLights Thank's I will check that, so for a fixed position UV to cover the whole room(my room is small) your suggestion is higher watt and sacrificing some visible light instead of lower watt and not cover all part of the room? I mean you prefer more glow when your UV is fixed ?

Are there any good light bulbs on the market that you could recommend 4 me to buy to put in my living room lamp?

[@Sam-sb2bq]

Thanks for your video! Much appreciated. Just wanted to also ask... I have painted a wall mural (that starts from the ceiling and goes halfway down to the floor, so 3.5 meters across and 2.5 meters down). If I mount a UV light underneath the mural, to the wall facing upwards will the effect be the same? (the mount would be hidden behind my TV and was planning to shine the light upwards from there) ... or does a UV light need to hang facing the mural dead on to have the best effect?? I´m really only looking to have the mural glow - not for party lighting. Thanks in advance!

[@UVBlackLights]

You can mount underneath, but the blacklight needs to be angled as best you can hitting your mural or else you won’t get enough spread to hit the top portion of your mural. Hope that made sense.
