Thread: Looking For 1/2 & 1 Watt Leds

    Default Looking For 1/2 & 1 Watt Leds

    I'm looking for 1/2 & 1 watt white output Leds that can be powered by two aa alkaline batteries. Runtime 2 hours minimum. Because of the situation i cannot use any regulation or resistors. Any suggestions as to the type & where i can purchase the above would be appreciated. I live in the U.S.

    There are very few (if any) 1/2 watt or 1 watt LEDs that can be DD'ed off two aa alkies. You'd need a VERY low Vf LED.
    I don't know the wattage, but SMJLEDs work great off of 2 alkies. You can get them from lambda (BST) and tritium (groupbuys)
    Got busted lights? Send me a PM and depending on the situation, I'll take 'em off your hands. I always like a good modding challenge.

    An H-bin Lux3 might work for you. At 3V, you won't have much current, but it should still provide a good amount of light (more than a 0.5W and possibly even more than an SMJLED).
    Streamlight: TL-3 Xenon, Vital Stream Scorpion-FB1, Scorpion LED SSC P4, KeyMate Silver (Nichia CS)
    Nuwai: 2x QIII TWOH (Green and Titanium), TM-313X Ti (QV1J DD 14500)
    Surefire: M2+C2-HA+Detonator, E2D, VG FB1+EXe, VG FB3+E2C+C2
    Vital Gear F2, Huntlight FT01, Jetbeam Jet1 AA and 123A, Fenix E1 (Silver), Luxogen LR5A-3W & LR12 CR2 (SCC P4), Spiderfire LR8, NexTorch Z1, Gerber Infinity Ultra (2x Green), Dae's UV 12LED

    See my GB here for 1/2 watt leds that will direct drive from 2 AAA's or 2 AA's.
