This light is very well made and it does the job to what you want

I use UV cured sealants for ammunition to make it waterproof. Everything is done by hand, so I used store bought UV LED flashlights using 3 AAA batteries a piece! These were inferior in every category from durability to finish to light saturation. My resins cure quickly and thoroughly.

Fits well in hand and on/off clicker is in the right spot. Great light.

Loon replaced my four year old light free of charge, even though I had no proof of purchase. The battery was corroded and welded itself into the light. I now remove the battery when not using the light.

The light is great, I especially like the adjustable beam focus.

Loon provides outstanding customer service.

This (was) a great UV light. But the P.O.S. Battery supplied with the light is a disaster. The UV light worked fine for months, and then started to fade. So obviously I un-screwed the body to replace the battery only to discover that the supplied battery had completely corroded inside the housing. It took me several hours of hard work to remove the battery, to then find the housing itself had corroded away. With the corrosion I cannot now insert a replacement battery. Let’s face it, this is a very expensive UV light, so why supply it with the cheapest rubbish battery available? I’m now left with an unusable very expensive piece of junk.
