I put together this little chart out of curiosity and I thought I would share it.
I found some equations for tungsten lamps, includes halogens, for the effects of altering voltage on the performance of the lamp.
I inserted a typical 100 watt, 12 volt lamp and looked at various boost factors up to 19.2 volts
Some intresting things were evident, besides and enormous increase in lumen output, the efficiency is greatly improved also. Of course, the price to pay is lamp life.
Based on experiments I have done, the equations look pretty good, but the lamp life, especially at high voltages, is probably an estimate at best for there are many factors such as the tungsten alloy, gas makeup, filament construction etc that effect life.
If one wanted a low cost superlight for a shootout...and lifespan was secondary issue, this is hard to beat
