[QUOTE="HarryN, post: 1007765, member: 69773"] The LED headlamps usually use drivers (led power regulators) with an input max at 5 volts. For that reason, you tend to find these with either 2 x AA (so max under 5 volts) or 1 x 18650 (so again, under 5 volts). Usually, the 3 x AAAs are a more simple design (battery / resistor / led). They work well for that price point, and I have made some, just not quite as efficient and AAA cells are a poor value for the amount of provided power. C123 (primary) and CR 123 (charge type) batteries are both in the 3 - 4 volt range, so that can make for a useful potential combination of primary and rechargeable cell. The 123s have similar lifetime, cold weather performance, and total power of the energizer primary Li. It is perhaps the most useful consumer cell out there for this reason. On line, you can get several good brand name primary cell C123s for reasonable prices, example surefire, streamlight, rayovac, Duracell, etc. Much cheaper than in the stores. Spend some time reading about recharge type 123s though to make sure that the one you are using really is fully protected. I toss them after 5 cycles even though they are rated at 100s, just to error on the safe side. They are cheap enough that it doesn't matter, and unlike brass, you cannot tell what is going on when re-loading. [/QUOTE]
