You could get a small cheapo timer and a couple of cfl's for reasonably cheap, and set those just to keep your light schedule right. Look in the clearance sections at walmart or home depot, i've seen $5 timers there. Small worklight fixture for about 8, couple splitters, and a few bulbs should come in around $30. Just one guys idea.

IMHO it would be better than leaving lights off for 2 days, can we say hermies?
