Can these lights produce a UV / Black-light effect?

So so. The controller that you'll use has to be able to create a kind of violet colour. The more LEDS you have, the better UV effect you get.

No, these markers won't wrk on the black light. These do wrk on the electrical lighted board.

I've noticed that it does, but doesn't really give off any light. I have these on the side of my house which is pitch black at night. They are amazing then but barely noticeable in daylight, but that's fine since I don't need them for that.

I would say No. I have them outside on my deck. This area gets several hours of direct sunlight. Even with this amount of light, they do not all work and they only work for a portion of the night. To tell the truth, I've not been terribly pleased with these. I'd look for something else.

Yes and they add a really nice "glow" as long as the light isn't blocked by a shade...then it would be too dim.

According to eHow and several other sources I have read, there is no UV emitted by LED's. Their spectrum is very limited and neither the high frequency end (UV) nor the low frequency end (Infrared or heat) are emitted. The result is a very efficient light emitter right in the spectrum to which the eye is sensitive.

The lights I have are at my other residence so I can't verify this..."I think they can but they may need to be wired differently to enable that feature". I remember the instructions mentioning something about this. Sorry, not much help.

Yes, anything flourescent or bight white will glow, it works just like a regular blacklight.

To the best of my knowledge.....no. UV would be visible as more of a blue/violet light to the naked eye and these bulbs put out a very bright white light.

They will cure the same. Uv lights just take longer than an led light. . Gelish has a great mini led light for 25$ . Just b sure 2 buy the plug in adapter. . Doesn't work great with batteries ;)

Yes but they would be VERY dim. Night light replacements.Odd coincidence, because I just put in candelabra to medium base adapters in my overhead fan so I could get MORE light.

I doubt it. I use them on paper for highlights on doodling art on paper and I've never seen them glow in the dark.

I'm not 100% sure but I believe there will be UV issues over a period of time. You may want to contact the manufacturer on this item.

All were black lights. I have used them with UV sensitive ink and clay for demonstrations with kids, and they work fine.

That's exactly what I did! No, not at all. The lights are as small as drops of water, and right on the copper wire. Hope that helped!

I honestly have no idea...if you can find them with an ultraviolet light, then maybe...it's very bright
