http://forums.offtopic.com/showthread.php?t=3658587 I wanted a bright flashlight. So I bought one. www.dereelight.com Dereelight DBS V2, runs on one 18650 li-ion cell. 2hrs runtime on high, lots more on low. Heres a pic some guy took of it shining the shoreline 1,000ft away Edit: I'm using these cells and charger http://batteryjunction.com/2600pcb-18650.html http://batteryjunction.com/wf-139-.html[/QUOTE] And you can buy the light from here: http://www.dereelight.com/new.htm Mine is a DBS V2 2SD 2SD means 2 stage---as in click once for high, click it again within 1sec for low-mode. 3SD has low-med-high DI from what I understand, you basically click the button repeatedly within one second of each click and the light steps up in brightness anywhere from 10%-->100% OP and SMO are orange peel or smooth reflectors. I prefer the OP because its more "floody" the SMO reflector throws a bit farther though.
