Streamlight Polytac, a reliable weapon light for 36 dollars
I just got my Streamlight Polytac LED in the mail. I've gotta say, so far I am very impressed with this light. I matched it up with an offset mount and this baby is bright! 130 lumens from a C4 LED. It's waterproof, shock proof, light weight, and made from a durable polymer. Goes for 36.00 with free shipping on amazon.
Has an effective range of about 25-30 yards. It'll reach farther, but it's stays visibly bright to about 25-30 yards.
