That's pretty cool. I'm pretty sure my 6 volt 1 million CP bulb says it's supposedly 55 watts on the base of the bulb. We could use Ohm's law to estimate the current if you know the voltage just before it blew (assuming the bulb really uses 55 watts at 6 volts). 55 watts at 6volts is 9.2 amps. That puts the bulb resistance around .65 ohms. So at 8 volts it was drawing around 12 amps. That puts power levels just under 100 watts.
