Lights, action.

Don Klipstein has a thing about lights and lighting. A big thing. The result is his Lighting Info Center. Including the Great Internet Light Bulb Book…Part 1.

‘It is fairly well known that Thomas Alva Edison invented the first reasonably practical incandescent lamp, using a carbon filament in a bulb containing a vacuum. Since that time, the incandescent lamp has been improved by using tantalum and later tungsten filaments, which evaporate more slowly than carbon. Nowadays, incandescent lamps are still made with tungsten filaments.’
