Streamlight has been making me happy over the last year or so. I have a PolyTac on my AK, and a teensy little 30 lumen streamlight nestled in the shoulder pocket of my ACUs for Supply Cage emergencies. I run a TLR-2s on my 1911. I'm also pimping the Surefire headlamp on my ACH for work, because Army life extends beyond the hours of 9-5. I fell out of love with Surefire after my 6P LED quit working properly and now only spits half of its advertised luminosity.
Oh, and I have a 5 million candlepower floodlight in the truck, for, you know.. blinding aliens and such...
