I just got the light on Saturday, and I have not really had a chance yet to go out into the country and crank it up and see how good it throws and how bright it is in the open. But I have turned it on the highest setting(2700L) for very short periods like less than 30 seconds. But it wasnt until last night that I noticed the flickering.
I was doing a ceiling bounce test to see how well it lit up the room around me, and I had done this before, but I always looked around the room at the light it was producing, but I didnt look closely at the beam on the ceiling til last night. When I did, I noticed that it flickers about once or twice every second or two. Its not a regularly timed flickering, its somewhat random in timing. It doesnt flicker all the way down to off/no light, but when it flickers it gets a bit dimmer, and each flicker only lasts a fraction of a second. Its pretty obvious though.
But when I switch down to the next lowest setting(1500L), or any lower setting, the flickering stops abruptly. I am using Orbtronics 2900mah protected Panasonic 18650's. All 3 were bought about 2 months ago, 2 weeks apart, and 2 were spares that only went through 2 partial recharge cycles(charge discharge and recharge), and the 3rd one was used in a single 18650 light, and was cycled for partial charge 3 times. So they certainly are not old, well used batteries!
What could be causing this phenomenon, has anyone else seen this with this light or with other high lumen lights? Is it a big deal, and what to do about it? Its only happening at the highest setting.
Thanks...
