I'll post a pic of whatever it is we end up doing. Leaning toward the pot. If that doesn't work for any reason, I can put the pot to good use...
And, yes, good old incandescent bulbs are great as a source of heat. I haven't been following the politics of light bulbs - will they be phased out in the near future? I'm not a particular fan of the twirly bulbs and haven't really tried the LEDs. I had one unfortunate experience with an early halogen that rather scared the bejeezus out of me - a fly landed on a lamp guard above a halogen which instantly shattered the guard (some sort of acrylic-y thing). Yikes.
