Physics

Efficiency for your bulb should have improved as the operatingvoltage increased. An even higher efficiency would have resulted ifa still higher voltage were to be used to power the bulb. Ifmelting of the filament were not an issue, discuss another limitingfactor to improving efficiency by increasing voltage.
