I'm new to the forums and flashlights. Just bought my first tactical type LED flashlight and I had problems right away. It's a Hugsby brand M2 CREE LED 230 lumen flashlight. Now it worked fine with some Surefire single use 123A batteries and when I tried the rechargeable batteries that came with the light I got a split instant of light then nothing. I am guessing that the LED/bulb has blown.
What I'm wondering is would you think it was a faulty LED/globe or the batteries maybe ? The batteries are Ultrafire LC 16340 880mAh 3.7v (was told they are 123A). I have tested the batteries on a multimeter and they are reporting 4.2v each. Any ideas as to what may be the problem. I don't want to keep buying bulbs/leds or the wrong batteries just for testing as they are kinda of expensive.
Thanks for any help you can give
