The Jan. '91 issue of The Institute (the IEEE's newsprint
newsletter) arrived today, and synchronicity of synchronicities,
there's a story on p. 6 (hidden as filler under the headline
"Intel's Newest Supercomputer" (no plug intended :)) about how
GE has just improved the electrical efficiency of halogen lamps.
They give the envelope an infrared-reflective coating.  No details
on what it is, but it's probably just a half-wave-gel thing.
This reflects much of the heat back onto the filament, keeping
it incandescent-hot, saving the electrical energy that would
have been radiated.  Since it works only on infrared radiation,
it doesn't affect the lumens in the visible spectrum.  They claim
an energy savings of 60 percent.
