i am the only person in my family who uses energy effecient light bulbs. in my house there are about 14 60-100w bulbs, if i were to swap them all out with 10w high effeciency bulbs, i would be able to power a 1000w TEC for about 6 hours a day without a change in our bill.
Besides, with the 3 high eff. bulbs in my room now, i have gone from 3x60w to 3X10w, so from 200w to 30w... thats a difference of 170... heh, 2w wont make that much difference.
and besides, how much does a vapochill draw?
