They are only on 9 hours and the actinics are 12. So even less than $16 a month. Nice.

LOL...Ok well I was off by just a little. Actually that makes more sense though. Since switching from 250's to 400's, my bill has only gone up about $8 a month at the most.

Thanks, its nice to know I am not paying $40 a month for the lights...Im not really sure where I got that number from. I think I just kind of assumed they were a big chunk of my monthly bill
