Waterproof and impact resistance ought to be high on the list of desired features, too. I bought some really bright, 150-Lumen Cree lights that seem pretty sturdy, but I dropped one from less than 4 feet onto concrete and it doesn't get very bright and dims quickly. The regular price at Costco is $19.95 for THREE and I got mine on sale for $4 or $5 less there, but cheaply made lights aren't good bets for tactical situations. These use 3 AAA batteries.
These lights really punch out a hundred yards or so and seem impressive, but the PD32 with over 300 lumens... good grief! And the prices aren't bad, either.

Amazon.com is a good place to look for stuff AND check out the user reviews, especially the first one by an LEO tester.
I've decided a lot of purchases, yay or nay, based on these reviews.
