DARKBEAM UV 365nm Flashlight Woods Lamp LED Flashlights Rechargeable 2 Pack

BEWARE!!! The TWO packs are two nice DIFFERENT very nice flashlights. For the pair versions... Like others here noticed ONE is White-Only product , but the other is hard to find nice 365nm blacklight !!! CONFUSING DESCRIPTION!!! The pair of flashlights are typically two DIFFERENT very nice flashlights. Only one is UV 365. I ORDERED 2 of White PLUS 365nm UV blacklight option , $21.99 per 2 ! : https://www.amazon.com/dp/B07RC52PQX It comes with two GREAT flashlights, but only one is UV. The second one is A300-T6 White ( no blacklight). The other is https://www.amazon.com/dp/B09PYZJYQW (very bright, focusable, strobe light, different brightnesses etc. Both are very well made, very bright, have recharging cable and many features, but I REQUIRE 365 nm blacklight I tried to order! The 365nm was real and not the crappy fake garbage 395nm that cannot ever show security ink, or rapidly recharge glow in the dark paint. 365nm is what you want, want the many youtube videos showing why. NICE PRODUCT! Now I bought 6

Interesting concept: a black light flashlight that allows you to select two different wavelengths of ultraviolet with a touch of the button. The longer wavelength is that of a typical UV flashlight -- 395nm -- which produces good fluorescent effects, albeit with a significant spillover of visible light. The shorter wavelength is 365nm, which also produces decent fluorescence, with considerably less visible light, although you do have to be somewhat closer to what you are trying to get to fluoresce. These have been fun, but for me this flash would have been more useful if the two wavelengths switched between UVA, and UVC (~280 nm), which would give the flash germicidal capabilities. Oh well, can;t have everything, I guess. As it stands, this flashlight is really more of a toy. although a well-built toy, to be sure. And for the price, a reasonable deal.

Bought flashlight to identify vaseline glass and it has turned out to be great for that purpose. I like the fact it comes with a rechargeable battery as well as has the ability to use AA's too. The ability to change between the 2 light frequencies is a plus too. Somethings really light up well on one setting while others light up better on the other. This light is only for use as a blacklight because you really can't see much of anything unless it fluoresces. This is a great flashlight for its purpose.

One battery did not work at all. Period. But I don't expect all electronic devices to be perfect. Would have returned for a replacement but only needed the black light to work.

I bought it to cure Bondic brand "glue". Since I wasn't sure which UV frequency that needed, it was convenient to have both wavelengths in one flashlight, and it was a nice bonus that it was rechargeable (or can use AAA batteries if needed). It does the job of curing the glue. I've tried both frequencies, and they both seem to work. I'm not sure if one works a little better/fast than the other. Its a lot nicer than using the little squeeze lights that come with the glue.

UV light works good and the flashlight has same glitches with charging and turning on; have to wiggle the cord that the light to get charging and you have to turn on and off and on again to get the light to turn on.

Rare to find a UV light that can flip between two frequencies. I have a UV meter and was able to measure the light output. The lower frequency (closer to pure) was about 60 micro watts per square centimeter. The higher frequency (further away from visible purple) was dimmer but still good (20 microwatts per square centimeter). In practice, you can be ~ 4 feet from something that is UV sensitive and it will glow (blood, urine, other stains).

My favorite thing about these is they don't require a constant supply of batteries. They are very durable and provide great light for there size.
