6 Pieces UV Black Light Flashlight Small Blacklight Flashlights Pen Lights for Leak, Pet Urine, Hotel Inspection, Dry Stain and Dye Detector, 5.2 Inches Long

My first reaction was how nice these are. They have a little weight to them and feel sturdy unlike the plastic body ones. Nice on/off button and a good pocket clip that works well on my jeans pocket. So far I am impressed.

Great little UV pens. You get what you pay for and these are perfect for small jobs checking everything from authenticating official items to activating ceiling glow stars in bedrooms. My husband's pen light is still going strong 6 months later that he uses to authenticate certain cards but I get about a month activating my children's ceiling stars before I notice the strength is fading (normal phenomenon for UV bulbs).

One stopped working almost immediately. We got them to search for Lake Superior Yooper Rocks, worked well.

Great buy. Great gift to give to ER doctors. Great for travel to check for bacteria in hotel etc.

Great price and they are much brighter than I assumed. Please note these are 395-400nm.

1 of the 4 does not work and I need them tomorrow for my class. The ones that work are great.

I bought these to use for my crew while conducting ID checks. These are a great product. They are very bright and able to be used during the day outdoors as well.

For the money , it is by far the best bang for buck .. I was almost in shock to see the distance it shoots the beam . It has a main center of light with a huge coverage around the main focal point .. I haven't ran the batteries to dead yet but with the amount of light they put out , it can't be a long run time . It's bright enough to use as a flashlight , easy 200 plus lumens . If your doing a search for fluorescents or hotel room , it's definitely going to do it's job . I will be buying again and again as long as pruce stays the same ... thank you for awesome deal and product !!!!

I keep on e in my Face paint kit to show the kids when I use neon paint... they glow.

Excelente, muy profesional y prácticos

Very bright black light. Flashlights are great so far battery life is good as well.

Great for price. Need a lower uv for rock hunting, but these lights are good for charging glowing items

Work alright. No as bright as expect
