Purchased these for a cashier friend. They are using them to catch counterfeit bills. WORKING GREAT FOR THIS.

Bought these for a science class but over half of them didn't work. Very disappointing, not to mention it ruined our class experiment. Don't waste your money

I bought this set of 15 to use with my geology Mini Miner group. I compared it to other UV lights in our collection. We have a lot of rock specimens, we use them to determine fluorescent minerals in the rocks. Not all UV lights are the same in bandwidth, power and light source to produce the UV light. The McQuarry lights are Powerful, about twice the illumination area as the WorkPro (and I think the WorkPro is a good product as well) the beam is so intense it heats up quickly. Keep this in mind when you are using them, don't shine is in someone's face and remember to turn them off frequently. Also, remember to keep the UV light off skin. Usually this is not a problem with a blacklight (365 nm) but the McCarrie product must not be exactly 365nm for its stimulating frequency. These flashlights act like they have a large bandwidth, encompassing 365 nm but go longer, toward 400nm and shorter towards towards 297 nm. It's a large bandwidth. As an example, a sample of Cleavelandite that we have contains UV sensitive purple apatite crystals. Under the McQuarrie light, these crystals are very bright with a salmon color while the rest of the cleavlandite is non fluorescent. I have a Batteries and Bulbs UV light which specifically states that its emitting frequency is 385-390 nm, and the color that is produced in the purple apatite is a pale orange-pink, which is about 600 nm emission. The McQuarrie light gives the exact same color but so much brighter. I am looking to see what the company specs are on these. Contrast this result with the Workpro UV light, which is definitely 365 nm excitation and the Purple apatite has no response. So every blacklight offered on the market is different in bandwith and wavelength of greatest response. Both the McQuarrie and the WorkPro pick up the UV sensitive strip on a $20 bill, but the McQuarrie is so much more powerful and has a larger radius of illumination. At two dollars a flashlight, this product is undervalued. We can easily give these away to our Mini Miners every year. And we will teach them the uniqueness of this particular flashlight.
