Tried and true EDC
Garreth 3/20/2021 6:53 AM
This has been my EDC light since I got it. I use it at work as a trim carpenter and it gets beat up a lot and only looks better and better.

The beam is perfect, the tailswitch has a subtle click, the clip works well. The UI is excellent.

I went with the Nichia emitters and the light it puts out is beautiful.

I have gotten many many lights since this one and I still haven't found anything that could replace it as my work EDC.

A near perfect light!

I highly recommend it to beginners and enthusiasts both.
