Are the LEDs bright enough to light up UV reactive paint from 3 or 4 feet away? How close do these need to be to the reactive material?

Absolutely. I haven't tested for various distances, but they're good bright little lights. They lit up neon stickers 5-7 feet away; they could possibly have done more; I just never tried.

It all depends on how much lighting is around you while looking at uv paint on ids from 10 inches away from the id it's pretty good

I read some of these other answers, and in an effort to be precise, I think they're complicating this. Assuming a dark room; assuming you point these directly at the object; assuming it fits inside the beam--the answer is absolutely yes.

I believe they work...I got the multi color LED and picked up the 12ft strips...they worked for me

You can visibly see the illuminators glow but it is faint, as is their usefulness. It will work if the object you're trying to illuminate is very close (within 4 feet or so) but outside of that the LED lights are very ineffective.

I don't now how to answer the lumin question, but I'd say that these are bright enough to light up your path a few feet from the light, but not even as bright as a 40W equivalent bulb (besides that the LED light is white and not yellowish).There are two notches in the back of these, so you only need to put in two big-head nails in a fixed wall, fence, side of staircase, etc. and you could hang the light. Dimensions: refer to the product, but about the size of a grapefruit qualitatively.

I have only ran them by hand, not on the bike yet. They appear to cast a wide beam and are very bright. If you look into them you will see spots for a while. They do not appear to shoot a long thin beam, bit will get the attention of anyone coming at you and will light up a trail very well. Ok, just went outside and touched the wires to my battery and the main part, brightest, of the beam is a good 4 foot wide at 20 foot distance. Hope that helps.

We use ours as work station lights. They are mounted under the wall cabinets and light up the counter top beautifully. We used 3 x 18 inch led strips to light up 6 feet of counter. They are only 18 inches above the counter, but they are good and bright. I think you would be pleased with the effect at 30 inches above the counter.

I have three paintings 18" X 22" and one 22" x 30" all four of them luminate very well. Im still very happy with these lights!! I hope that helps you,,,I agree with the other comment as well. It's your own interpretation of illumination. I have a couple hard wired painting lights in another room they of course are like a spot light and I use a dimmer to keep the lighting right for my own taste. I have three of the Rite Lite LPL602B in my living room I use with the 18" X 22" paintings and the ambience is perfect. occasionally Ill will even dim them a bit .

Very, very bright. They are on the smaller size about 5x4 and about 4" deep. However they look clean and put out a flood pattern but the light up reflective signs from 100`s of yards away. So far no issues, brackets are a little flimsy but light housing is solid. I would biy again

I have them mounted bout 14" off the ground. They will trow the light a easy mile. The light expansion isn't bad but they are more of a spot than a flood.

I shoot lots of RE. Would never consider LED's for anything larger than a powder room. Need the power of a strobe. These lights great for video interviews (not in a very large space. Probably not more than 6-8' away from subject) and headshots.

Radiates about three foot radius, distance will depend on the light requirements of the plant. LED puts out minimal heat, so it should not scortch the plant. Have one light on 12 hr timer to supplement the Alaskan winter "daylight",So far so good, because my orchids are spiking blooms and orange tree has not dropped it's fruit or leaves. Good luck

I am not sure of the distance the light reflects but tomorrow I wll try to measure it and let you know. They are really bright and I am pretty sure on the highest beam you would get that distance or close to it.

The LEDs are quite bright. I have one up at the peak of the roof line and it puts out plenty of light for my "older" eyes. These have worked out so well that I am about to purchase a few more.

Yes, they are small UV lights you may order or buy locally.you just need the number off of the bulb.

I would google ultraviolet vs led and read the answers. A good one was this one www.nsinails.com/.../led-vs-uv-by-rise'-c... Hope that helps!! Crystal

I have the halogen 10W bulbs. It is almost a matter of preference. I have them along my driveway which is curvy to mark the outline. Those are on the outside edge of split rail fence at the vees. They are about 14 feet apart. On a gravelled path I have them about 10 feet apart and they seem to illuminate sufficiently.

depends on how you aim them. mine light up the road about 100-150 feet ahead.
