How many KWh does a 600 watt bulb use?

Answer 1

I'm surprised that you are asking about a 600 watt flourescent tube, since most flourescent tubes are in the region of 30 to 80 watts - I can't think where you would find such a huge flourescent tube, so you might have meant a 60 watt tube. However, any electrical apparatus rated at 600 wats, whether it's a flourescent tube or a motor or a heater uses six tenths of a unit of electricity in one hour. 1000 watts would use one unit in one hour.

Answer 2

The wattage of a bulb is how much energy it consumes in 1 sec. So the bulb you are talking about converts 600 Joules of electricity into light energy every second.So to sum it up the wattage of an item is how much electricity it uses each second in this case 600 Watts. If this isn't what you are looking for i recommend rethinking your question.

Answer 3

600 Watts * 18 hours = 10,800 Watt hours

10,800 Watt hours = 10.8 Kilowatt hours.

A object rated at a certain wattage (ie 60 watt lightbulb), indicates that it uses 60 watts in one hour. All ratings are by the hour usage.

Answer 4

.6 kwh

If you ran it for 24 hours then you would use 14.40 KWH per day. In Montana in December of 2012 we pay between .10 - .11 cents per KWH. That 600 watt bulb would cost $43-$47.52 per month (using 30 days per month) if it was on 24 hours a day.

Answer 5

It uses 0.6 kWh (0.6 unit) each hour, which cost about £0.10

Answer 6

A 600-watt bulb uses 0.6 kWh (kilowatt-hours) of electricity for every hour it is on. If the bulb is on for 3 hours, it would use 1.8 kWh.
