The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
A 100 watt light bulb does not cost more that a 1200 watt hair dryer. The average price of a light bulb is about 90 cents whereas a hair dryer can range up to 20 dollars.
The cost of the bulb is in the 30 dollar range. The cost to replace it depends on the hourly rate of the person changing the lamp and the additional cost of a bucket truck to reach the light fixture. This price will vary throughout the country in which you live.
I have seen it both ways. Usually it is the bulb which is a few bucks. The ballast will cost more and could cost $15-$30 bucks depending on type. If you have another bulb that is working, swap it with the flicker light and see if the problem goes away. If the swapped bulb works, I always put the bad bulb in the fixture where the good bulb came from. If the bad bulb now works, you could have a seating problem with the bulb. If it flickers, replace it.
about 2.00 dollars. it depends on the size and shape and the number of volts you get!
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.
a nightlight can cost a few dollars depending on the type of nightlight it is such as a bulb or sensor. the decor of the nightlight can be factored in the cost as well.
i dont know ether if you get the answer can u send it to me plz
The first commercially available light bulb cost $1 in 1881, which was three years after Thomas Edison developed the first practical incandescent light bulb. The Seattle Times reveals the $1 price in 1881 translates to $23 in 2013. By 1910, the cost of a light bulb dropped to 17 cents.
small, cost efficient light bulb.

Convert the watts to kilowatts, multiply by the time to get the energy (in kWh), then multiply by the rate.
