**And again: BULL****! Repeating the same lie a second time, does not make

it the truth. LEDs are not that efficient. White LEDs are approximately
the 
same efficiency as halogens. Cree and other high end LEDs are around 4 X
the 
efficiency of halogens. IOW: Around the same efficiency as discharge
lamps.

**It doesn't matter. I'm commenting on your ignorance WRT the efficiency
of 
LEDs vs. incandescents.
