I know with early model HID's used as primary dive lights, you could not burn them out of the water for very long without risking excessive heat build up that would destroy the bulb and ballast. Newer designs have supposedly solved this problem, but I still hear of the occassional problem such as you experienced (I guess the ATV HID's intended to have some wind blowing across them as a secondary heatsink.) I love the color temps that HID's offer, the difference in an underwater cave is amazing.

ya i had thought of that too. Is it still a good rule of thumb to wait a few minutes before turning your light back off after you turn it on, so it goes thru a burn cycle?

One other practical question, just how tough is you battery and where are you putting it in your helmet? I think this came up on another thread somewhere but having any hard objects inside your helmet greatly reduces the effectiveness of your helmet in a high impact scenario (i.e. a rock falling on your head). The crush space in a helmet is what makes it strong enough to stop a high speed object. Filling that space with something hard is a bad idea. Also, maybe it's just me, but I don't like the idea of having a battery that could break or leak inside my helmet.
Just my .02,
