Depends on your electric rate and lamp wattage, but for formula is this:
100 Watts X 24 hours / 1,000 KWH X elec rate .08 = .192 per day.
If you are trying to decide on weather to buy fluorescent vs regular consider this:
Example: 100 Watt lamp costs .50 and is rated for 1000 hours.
100 Watts X 1,000 Hours = 100,000 Watts / 1,000 = 100 KWH
100 Killowatt Hours X Electric rate .08 = 8.00 + .50 cost of lamp
Total cost to run that light bulb (on average rated life) is $8.50
That's why the new fluorescent lamps are so cost effective. Do the math.
18 Watts (100 equivelent) X 10,000 Hours = 180,000 W / 1,000 = 180KWH X .08 = 14.40 + 6.00 cost of lamp = $20.40 Total. Sounds higher but the lamp lasts 10 times longer. So 20.40 / 10 = $2.04 each
It's a little bit more upfront but easily pays for itself in the long run.
