Reviews:
1. These lights seem to be about all the little extra touches, from the forward clicky to the quality lanyard, JETBeam looks to have gone the distance to make quality light affordable, rather than the other way around. ------Dave Wise

2. The beam is clean with no artifacts and has a color temperature very close to pure white, good to see that most recent LED's are consistently producing pleasing white tints instead of the occasional blue/green hues of earlier generations. ------Meveel Lee

3. The Backup series lights are well-designed, easy-to-use, two-stage lights with a good, balanced beam pattern – but with much higher output on Hi than I've seen before for this emitter type. Runtimes are also excellent at both levels, especially on Lo. A nice series of lights at attractive prices, I am sure these will do well for JetBeam. ------Selfbuilt
