Lighting selection help?

[gjk]

I am considering lighting for a new build. Can anybody give me monthly cost to run their 400 watt metal halides? Of course where you live has a great bearing. I am in the southeast in coastal Alabama. Any input on what the monthly cost would be for three or four 400 watt halides?
