Re: Lamp Current vs Voltage

O.k., well, given that it's so cheap to make it, is it possible to design a circuit with redundancy, such that if one component fails, then another one takes its place? Or even just three complete units, with some sort of a sensor which would 'decide' which one to feed electricity to, and which to d...

Re: Lamp Current vs Voltage

John Brown: according to that software I downloaded from G.E.:<p>10% overvoltage produces: 138% light output 119% efficiency 29% lamp life (!) 116% watts 104% color temperature.<p>And a 10% undervoltage produces: 70% light output 82% efficiency 400% lamp life (!) 85% watts 96% color temperature.<p>B...

New info. just in...<p>Found the following from G.E. Lighting:<p> http://www.gelighting.com/na/specoem/hicalc.html <p>At the bottom of the page is a link for some (very old) software for calculating "how differences in voltage affect life, light output, and color of Halogen and Incandescent lamps." ...
