A few weeks back, I got a few of those little frog type LEDs from PBK:

Great, but they chew through batteries. The whites use 2 3V lithiums
(very thin), and I didn't check what voltage they put out to the LED
(presumably 3V or so, given the band gap needed to produce the blue
part of the spectrum). At $7 a peice, and only seeming to last for a
few tens of hours, that's $14 every few weeks per LED.
OK, so goodie, I just constructed a battery holder for my two whites
on the front of my helmet. A little heavy, but should work. My drill
holls were small enough that it should even remain water resistant!
OK, so damn, just opened the red one, and it's only 1 3V lithium,
supplying 1.4V to the red LED, as expected. Anyone sacrificed their
red led yet to find out whether the little IC in the resin is capable
of voltage regulation, and hence whether the LED can be safely
supplied with 6V?
