White LED's are cool (and kewel too!)  and extremely cheap lighting. The
prices have dropped precipitously, and should pay back very quickly.

Why are they seldom mentioned as a means to save energy?

Will they become mainstream before the energy saving specialists (that would
be us) embrace them?

I know their light takes some getting used to, but the up side is
tremendous. For 1 thing, they save nearly double in cooling season. That's
important in the Southern US where cooling is used 8-9 months out of the
year.

I suppose LED's are best for point lighting rather than general area
lighting in home settings at this stage in their development. However, they
should be fine for shop, cabin, and security lighting.

Thoughts?

  Save energy compared with what? Last time I checked, white LEDs were
about as efficient as incandescents, much less than fluorescents. Has
their efficiency improved recently?

 The replacement cost for an LED is much higher, but life is much longer,
meaning fewer or no replacements needed.

By the time an LED fails, the cost will be pennies.
