[Elecraft] totally OT, except to the extent that it's QRP: LED lamps

How are the power supplies in these little  beasties?  Are they noisy?  Could 
they be?

I just replaced four gas-guzzling  incandescent lamps in my dining room 
chandelier with four LED lamps that  screw into the same bases. Went 
from 240 watts to 6 watts, total.

The  usual complaint about LED lamps is the cost. But prices are coming 
down  fast: these were only about $4 each at Costco. Each contains 21 
white LEDs,  and they basically last forever, which means I won't 
constantly be replacing  lamps in this fixture.

If the world converts to LED lighting, we won't  need to build any more 
power plants, and we can all use KW amps guilt-free  :)
