Questions about this light come up at irregular intervals. The reviews have been fairly negative; the 80 lumen claim is inflated, for one. The beam quality is not very good either. If you want a really nice 2 x 123 light, bite the bullet and get a SureFire E2, E2e, or 6P. Then I can guarantee you won't be dissapointed. The cost difference, if you shop around, or buy on from eBay, isn't all that much, compared to the *huge* increase in overall quality, and that mystical, perfect SureFire beam of light. Trust me on this. If you absolutely can't afford a SureFire, then you can buy a Streamlight Scorpion for *less* than $50, and it too is a far better light, IMHO.
