Yeah, someone had to do it /ubbthreads/images/graemlins/smile.gif
Besides after the LED drop in upgrade, there is no turning back anyway, so I might as well have some fun with the bulb. What I did was hook it up to a battery pack of 4 x AA NiMH hot off the charger, the cells still warm, registering 5.55V for the entire pack in its holder.
The Mag 2AA bulb was already somewhat blackened, it's terrible how even a fresh bulb can turn black when it's not even through its first set of Duracell AA alkalines.
So what happens? The bulb registers 400mA on my DMM, and lasts for around 20 seconds, but it's frighteningly bright. About 5 times as bright as it usually is. I'm thinking, it can do that? Then suddenly, no more light. I switch the DMM to continuity check mode and get no beep, but I get a digital reading, surprisingly. Normally, the DMM just says "1" when there's no connection. I switch it to 2000 ohm resistance mode, and I find out I now have a nice 317 ohm resistor. It still conducts some current, but like I said, it packs some considerable resistance.
