And not all of us have an 'abundance' of Luxeon, Cree, etc. LED devices to
experiment with. 8-)

LED's are far superior light emitters than filament lamps because in
filament lamps so little of the energy is converted to visible light, and
most is turned into infrared (ie. heat) - it's not as little as 1 percent
though it is a small pro****tion.

Even el-cheapo 5 cent LED's (not intended for use in automotive
applications) convert almost all the electrical energy passing through
them
into photons (ie. light), precisely how/where in the very narrow visible
part of the EM spectrum depends on the doping, etc. of the material the
functional part of the LED is made from (not including LED's designed to
emit invisible light such as IR led's).

So yes I know what I'm on about. No I do not have any of these Cree
devices,
and I'm yet to find a luxeon device that can used a drop-in replacement
for
any of the standard types of interior automotive lamps commonly used, or
for
any of the standard types of indicator or brake lights commonly used,
without having to add additional electronics to drive them, and creative
ways to heatsink them. 

So I don't think that the high-powered LED devices are really the answer
for
replacing the common types of small filament lamps used in most cars, at
least not yet until they can be made into proper drop-in replacement
devices
that don't need special 'interface' hardware, etc.
