I bought this light in Janyary on Ebay ($160 at that time) and used it for 6 dives since then. Now the light doesn't work anymore as it should be. When I close the battery compartment, the light stays on (without having touched the button). Pressing the button a few times turns off the lamp. After it is off, there is no way I can turn it on again. I have to unscrew the battery compartment and close it again to turn it on :S. I cannot use it as it is now... I contacted the seller on Ebay. He says the warranty is already passed (only 3 months
). I can only get a refund of 20 dollars... Does anybody have experience how to open the lamp and get to the electronics? Are the electronics in the lamp part or in the battery part? Do you think you can close it afterwards and make it leaktight again?
