FAQ about Uv Led Flashlight

what happens if you look at a uv led light? i was playing with my grandfathers uv led flashlight to see what would glow under it and i looked at the light but not directly from the source, if you do know thie answer please post because i am really worried, i also did not use special glasses so its that a problem. Plus i only used it for about 3 minutes. Any damage should have shown up within a day or so.
It probably was not very strong or you did not get too much of it in your eye. It could also be close to visible wavelengths, ie, not terribly damaging.
But don't do it again !

what is the advantage of having a UV LED flashlight compared to a regular LED flashlight? I had a regular 51 white LED flashlight that i got off ebay. and it worked just fine, I'm going to buy another led flashlight i'll be using it for camping and around the house. does a UV LED flashlight create more light or can you see better? UV or ultraviolet is not visible to human eyes. Buying a UV flashlight won't be any use if you want to see something. UV flashlights are frequently used to make hidden marks glow so they become visible. There are marks like this in the new bills and on passports and things like that. But you're not seeing the UV directly, just the glow caused by the UV. See the wiki article at the link below.

UV vs IR LED's (making a flashlight)? im curious as to how they compare and which ones are better for certain situations. The reason i need some LED's is to make a bike light. Thanks Aint gonna do much good to make a light for a bike with either one! Humans cant see them to begin with. They both fall out of the spectrum of visible light for humans.

Document and forgery analysis: UV light can sometimes show alterations and erasures to documents. Alterations or changes will sometimes become directly visible when illuminated by UV light. UV light can also be used as an exciter source. Alterations sometimes emit IR light in response to a UV exciter source. Use the UV light or a flash behind our XNite330 ultraviolet filter in conjunction with a IR filter (such as our X-Nite 1000nm) and an IR sensitive camera. This technique is sometimes called IR fluorescence.
Crowd and access control:

Crime scene inspection:
Currency and Bill verification: Many currencies contain a UV fluorescing strip.
Leak detection:

Rodent detection:
Scientific, laboratory and educational analysis:
UV Curing: UV light is used to cure many special epoxies and glues. Special adhesives require UV light to set up. This is usually accomplished using expensive, plug-in sources. We have a special UVCureMX light designed to rapidly cure adhesives.

How can I tell if a UV LED is emitting true UV light? I bought a UV flashlight off ebay, and im trying to figure out if it emits true UV light. How can I determine if it is? The best way to tell if a UV light emitting diode is in fact emitting UV light (and not just purple) is to see if any UV reactive substance is excited by it. Laundry detergent, paper, and some plastics all contain chemicals called optical brighteners. These are chemicals that fluoresce under UV. Especially the more expensive versions of each respectively. try spreading a little laundry detergent out on a glass or wood surface and shine the light on it in a dark room. Since laundry detergent it essentially clear it will appear to be the same brightness as the surface it is on if there is not UV (verify this with an incandescent flashlight) but the detergent will be significantly brighter under UV light.
Almost all "white" LED's emit a significant amount of UV. A cheap UV flashlight is made by blocking the visible light rather than the UV, which is the standard configuration. These UV LEDs will generally only emit UVA, the longest of the UV wavelengths and the least useful for scientific applications. A true "UV" emitter also emits UVB and sometimes UVC the progressively shorter wavelength variants. Here is a way to test if you light emits UVB or UVC:
glass absorbs UVB and UVC but not UVA very well. This means that if you shine a through a piece of glass, the UVB and C will be "cut." So to test if there is UVB or C present coat both sides of a piece of glass (preferably thick glass) with Laundry detergent. apply the detergent such that the edge of the section on detergent on one side is right next to the opposing edge of the detergent on the other side. (I would use a piece of black tape to mark the border) Then shine the light on the glass in a very dark room (I suggest waiting 5 minutes for your eyes to adjust) then look at the glass with the light on it for a few minutes. You should begin to be able to distinguish a difference between the two sections of detergent. The greater the difference between the two the more UVB/C is in the light emitted by the LED. If you see no difference it either means that your light only has UVA or the glass is not blocking enough UV. BTW I wouldn't use a "UV" blocking glass for this test as it will also block UVA and skew the results.
Final note: UVB should be considered as hazardous to the eyes as a class 3 laser, follow the same precautions. UVC is as dangerous as class 4. more on that here: http://en.wikipedia.org/wiki/Laser_safety
