## Questions & Answers

**Q: Will this light dry and harden UV glues, like those used in fly tying?**
A: Works great for the "Damn Good" brand UV glue.  I used it to fix a broken pair of glasses.  The frame around one lens had broken, and I couldn't get new frames for the existing lenses.  Just made the mend last night.  I'm not certain how long an exposure ti takes--I gave it about 2 minutes.  The glue's surface was still a little soft,  but an hour later it was completely hard.   Quite a bright light and I would be careful not to expose your skin or eyes to the beam.  I will use it for fly tying as well and expect it will work very well.

**Q: how long to completely cure and what brand of uv resin has anyone used with this light?**
A: works great with loon, solraez, gulff probably the fastest. Average cure 10-20 seconds is my estimate, get a good 18650 battery though.

**Q: One part of the description indicates it operates up to the 405 nm another says only up to 395 which is it?**
A: There is 2 available nm that I know of. 365 and 395. 395 has a more purple more intense beam. Better for resins and glow stuff. 365 has a less visible beam better for seeing uv marks or ink doesn’t work as well for drying resin or charging glow in the dark stuff

**Q: I have two cr123 batteries which way do they go in? It says use cr123 batteries... then how do they go in??**
A: + goes in first

I got this light to see how much of a crime scene the cats have left around the house. This light shows there’s a lot of crime in this house.
