    F-F-F-F-F-LICKERING!!

    [ QUOTE ] Pellidon said: My turquoise one was flickering, well more of a slow oscillation bright and dim. New batteries did not help but removing the foam spacer and scrubbing the threads and battery solder blob seems to have done it. It travels in my pocket and sees all kinds of pocket grunge...

    KL1 on E2, 123's have different discharge rate?

    Re: KL1 on E2, 123\'s have different discharge rate? 2 issues: 1. Heat - front cell gets hotter. 2. Transients - front cells may have to handle higher pulsed transients - as it is a switching regulator. Rear cell may have transients smoothed out by the front cell - much like a capacitive...

    Effects of EMP on LED Lights?

    Re: Electromagnetic pulse Having worked in an electronics test lab, where I performed lightning tests on the subjects (amongst other tests), I can tell you that nothing to do with high voltage/current is predictable, and that while equipment may be able to be proofed against most near lightning...
