I mentioned this briefly in the multi-media section, but here's a bit more detail. I have a 100mw (actually puts out about 130mw avg.) 473 blue Lasever module, and I have run it off and on ever since I've had it (for almost 2 years), but never more than about a half-hour run time.
Tonight I had it set up for a time tunnel in my garage for a Halloween display. It was cold outside (well, not real cold but around 50-55F). Well, it ran fine for a while, maybe almost an hour, until the beam began to get dimmer (there were some kids hanging around and one asked which was more powerful, the red or the blue, and that drew my attention to it) and suddenly it just winked out. A few seconds later, it came back on, nearly full power, but winked out again. Then I unplugged it, and the case was very warm (not so hot you couldn't touch it, but pretty warm). I left it off for the rest of the evening, until I shut everything down.
After it had cooled off, I plugged it in and luckily it came on and seemed to work fine.
Anyone have one of these Lasever (or similar) modules? I thought these things were for continuous duty, as they are designed for laser shows and such. I have had the case get warm before, but it never cut out like that. I was afraid the thing had died on me.... Why would it overheat like that, especially if the air temp is below what is considered "room temperature"?
