I'm still amazed people are falling for this LED scam. Sure,
LEDs
have their place and they can used to great effect in certain
applications, but completely replacing older incadescent in
every
way is ludicrous. You see any LED car headlights? Spotlights?
Floodlights? Of course not. They just don't have the
horsepower.

As for these silly overpriced head band lamps and $150 machined
alum
AA flashlites, it's all bogus. Sure, they're better than total
darkness, but barely. I want some serious candlepower, not
yuppie
outdoor sportsman chic.

As I understand it, the primary limitation on light output from an
LED is the temperature of the LED in operation. At output levels
exceeding 3 watts, at the present technology, the internal
soldered/brazed junctions melt and the LED fails. Due to the
brief time a "flash" LED is illuminated, such is in a cell phone
camera, heating isn't that much of a problem and higher output
levels can be attained.
