SF E1B head on E2E body

CSI304 · Dec 24, 2009

I installed my E1B head in my friend's incandescent E2E body running 2x CR123A.. some how it flickers on both high and low, is this normal? I am guessing he might new need batteries, but I don't have any experience with SF LED lights having a low battery indication. Any input is appreciated.

I believe two cells is really overdriving that... I would turn it off now and just use one cell..

I believe the E1B is designed to use 1 CR123 only, so driving it with two cells has probably damaged the driver and/or LED. Put it back on the E1B body, and use one cell to power it. If it still flickers, it's damaged, and, because you used it improperly, Surefire may not honor the warranty...

Running on li-ion [3,7v] is already dangerous... :crazy:

You do have options for turning an E2E into an LED, but it'll run you about $80 either way.
