UV Lamp 254nm/365nm 4W Portable UVC/UVA Shortwave Longwave Lab Batteries Included AI-0UV19

The Long wave part of this light is ok, but the short wave works really well for the price. Photo is an Idaho Opal using this light under short wave (background was edited out)

These are awesome for checking out fluorescence in rocks and minerals. Some you would never guess would fluoresce. However it’s poorly made and pieces tend to fall off as you’re installing batteries.

This item seems to work as advertised. I first charged the included batteries then set about using the item. The battery charge did not last even 1 hour before crapping out. Looks like I might spend more time charging the batteries than actually using the unit.

Works great! Light was about 3" away from stones. 4th picture shows lighting in room.

Doesn't work as described ... I had no problem with company... But this light I bought was completely useless. Bought it to survey my fluorescent rock collection... Had to hold it 2 inches away and it still didn't work... I'll be more careful in my purchases from now on....

I have used these type of UV lights for years, This is one of the best for a portable I have seen. The seller was very responsive to my phone call about the included rechargeable batteries that were included

Not like a simple UV flashlight. Much more fragile. Pay attention to the instructions that outline the care that needs to be taken with the light.

Product worked great and includes batteries and a charger
