I went to BassPro the other day and was looking at some Surefire flashlights.  When I was there, I noticed the StreamLight brand of lights.  They look like they are made very well, and they are about 1/4 the price of a Surefire light.  I was looking at the Streamlight Twin-Task 2D light. I liked the fact that I can turn on 5 LEDs, 10 LEDS, or just the Xenon bulb.  I think it was around $40.

Are these good lights?

I have an M3 on S&W SW99. I love it.

i have a scorpion that has served me quite well
