Wow, I'm kinda surprised this isn't more widely known.  

I've seen people use incandescent bulb lamps under sinks in houses that were
"closed up for winter" as poor-man's anti-pipe-freezing tools, and at least
one radio club that was having radio problems with a mountain-top site that
had plenty of power, but no built in heating system, use a 100W bulb and
some judicious use of cardboard (around the radio, to keep the heat from
rising up the cabinet), to keep a crystal on-frequency until repairs could
be made the next summer.

Drop-lights... they're not just for lighting anymore!  (GRIN)
