CU6 - 440 lumens (Ultra-Violet)

CU6 White-Ultra Violet Output

White light output or ultra violet light output, we got you covered.

Purpose built for law enforcement and investigative use, the CU6 allows you to use 440 lumens of bright white light, or 3000mW (365nm) of pure ultra violet light.

Uses of 365nm UV light

365nm LED lights are much more expensive than the traditional 395nm LED lights. Uses of this frequency of UV lights include:

- Ultraviolet Fluorescence Excitation
- Sensor Light
- UV / INK Curing
- Use UV Light to Spotting Germs
- Checking ultraviolet inks in currency and ID's
- Credit cards- MasterCard have "M C", Visa has an eagle in UV ink.
- Activation of fluorescent inks/dyes used as anti-counterfeiting measures
- Checking hand stamps at clubs
- Examining artwork and glasswork for hidden repairs
- Find urine stains (i.e. at the hotel before you hop in bed!)
- Scan a crime scene for foreign materials
- Scorpion Illumination, Scorpion hunting or avoidance
- Fluorescing diamonds - some will glow in the dark
- Fluorescing dyes used to check leaks

"Received my CR6 earlier this week, and first impressions are very good indeed. Solid, good fit and finish and a nice responsive forward clicky switch. Mode switching with the side switches works well (although they can be a bit tricky to locate in the dark) and there is a separate memory for the white and colored levels. There are five well-spaced levels on the white beam, but only three on the red beam - this is made up for by the secondary LEDs which provide a more diffuse lower level red, plus the extra colours.

I'm pleased to be able to report that the unusual beam profile caused by the side-by-side reflectors is absolutely not an issue in real world use: the white beam actually exceeded my expectations - very clean with good throw, and the asymmetric spill pattern is not really noticeable in outdoor use on either the white or the coloured beam.

Very interesting light with lots of possibilities. With a multi-purpose light like this there's always the worry that it will be a bit of a compromise, but it seems that Nitecore have got a lot of things right with this one."

Great product

Just got mine a couple of days ago, and it's great. Everything works as advertised. UV light is very pure and works better than my other two UV-only lights, picks up even the slightest details. Don't look at your kitchen or bathroom with it, you'll be terrified :)
White light is very bright, nice beam too.
Colored LED lights are a bit off-center (red is slightly to the left, green to the right), but I guess it's part of the construction.
Overall it's well worth the money, you won't be disappointed.

Functions well .. 365nm UV

Functions well .. 365nm UV is extremely pure and does not contain blue light components typically observed in cheaper UV LED torches or money detector type products.
