ok so i read the FAQ's.

a 1000 watt light uses 1000 watts per hour.

so heres my math.

worst case i'll be running 16 hours per day for 30 days. so thats 480 hours

3000KW = 3,000,000 watts or 3M watts

3,000,000/ 480 = 6250

So based on my math, running 16 hours a day, i can run about 6250 watts per hour and maintain my 3000kw hour usage?
