Reviews:
1. 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

2. 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.
