I am what one would call a "frugalista", and a retired engineer

In my mancave, in the summer, I put in the 9W CFLs to
cut down on the air condx load. In the winter I put in
100w incandescents to normalize out the load on the electric
space heater...
In the summer, the light is free, in the winter, the extra heat is
free.
I probably save 2 or 3 dollars a year. But, just the feeling that
I am taking advantages of the two technologies, makes it
something I want to do....

I am a BIG fan of LED light sources. Up to now, the cost
tradeoff doesn't make it attractive for me for house lighting.
For flashlights, camp lanterns, emergency lighting --- I am
enthusiastic about it.....
Some day, maybe not too far off, they will be mass produced in
a way to make them more cost effective..... I'll be one of the
first in line for the conversion.... but not today.

There is an article in Time saying that just when it looked like
incandescently were dead, they are coming out with more efficient ones
that meet the guv'mint standard.

That's right. A company called ADLT has what they call a "2X Lamp" which is
a halogen incandescent but with substantially increased efficiency such that
it draws 50 watts but gives the output of a standard 100 watt bulb I think
it's rated for 1500 hours life, but I haven't seen a price or found a
retailer.

It sounds like a good idea, but I'm wondering if the LED train now has so
much momentum that consumers won't consider anything else when they think
high efficiency.
