About 7 cents an hour.
ahm...depends on the cost per watt charged by your local provider... how much is it?
two 40 watt bulbs in 24 hours use: 2*40*24 watt hours in practical uses, kilowatt hours are used divide by 1000 to change the units thus two 40 watt bulbs in 24 hours use 1.92 kilowatt hours

a 100 watt bayonet
About $10. Do the math. Amps x Volts = Watts. A typical dryer is 30 amps @ 240 volts. That's 7200 Watts. Average electricity cost is $.07 per 1000 watt-hours. So...if you run the dryer for one hour ...it will use 7200 watt-hours. 7.2 x $.07 = $.50 per hour of usage.
A customer can purchase a 1000 watt grow light from a website called Greners. The cost to purchase a 1000 watt grow light from the Greners website is around an average of $500.00
If it is 1000 watts then it produces a 1000 watts. A watt is 1 joule/sec.
ahm...depends on the cost per watt charged by your local provider... how much is it?
25 watts * 24 hours = 600 watt hours = 0.6 kwh {1 kilowatt hour = 1000 watt hours} 0.6 kwh * (0.085156 per kwh ) = 0.0510936 or about 5.1 cents
A 0 Watt bulb does not consume electric power so the cost is zero.
The wattage measures an instantaneous power consumption of a load. You get charged by Watt Hours. A typical cost per 1000 watt hours might be around 12 cents.
You will have more light but at a lower cost. They produce much less heat so that wouldn't be a problem.
W*cost*khw/1000
a 1000 watt bulb used for 24 hours consumes 24,000 watt-hours of energy, or 24 kilowatt-hours or kWh. That is also described as 24 Units, each costing around £0.15. So the toal cost would be about £3.60.
The cheapest is about $1 per watt. So if you need 1000 watts it would be $1000 for equipment and installation.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
