Re: Extend the life the TV lamp
I assume this is a joke. Lamps go out because the filament eventually burns
through.

That's 20 percent more light output from the 150 watt bulb when running at full voltage. ... and put a 150 watt bulb in one of a pair of lamps and compared it's brightness to the two 75 watt bulbs in the other lamp. ... The filament of the 150 watt bulb is further away from its base, so there's a longer thermal path along the filament supports to suck heat away from the filament, and because it's further away from the filament, the base obscures and absorbs a smaller percentage of the radiated visible light. ...
