I'm not experienced with products of this type, but it does look very promising. The 150W (with the free Amazon shipping) seems like a pretty good deal:

Question: do these emitters put out a constant 150W, or is there some temp sensor built in that regulates the temp to a prescribed setting?
EDIT: Looks like this socket would sense the temp:

Oops, It turns "on" at 35 degrees, which is too low a temperature. I would want to see a unit that turns on at 45 or maybe higher temps.
