Very nice! I didn’t know it was possible to substitute the optics in this light. The build quality is phenomenal for something you can buy at only $10 USD. Also, it’s not jet black… but a very dark brown, kind of “titanium brown” if you will. Really nice color.

My only real gripe on the Jetbeam U other than low not being moonlight is the screw threads being rather short.

For comparison, just check it out compared to a Fenix L0D which has the “appropriate” width of screw threads.
