can someone tell me how much it costs to run a sunbed for 30mins
it has 10 x 100 watt bulbs

thankyou

10 x 100 watt bulbs mean that it is drawing 1000 watts (1000 joules a second). Electricity is sold in kilowatt hours (kWh), that being equivalent to using 1000 watts for 1 hour. In half an hour at 1000 watts you will use 1/2 kWh, so take a look at your last electricity bill and see how much a kWh costs, and half it.

just looked at my electric bill and its 11p kwh , so its under 6p for 30mins, seems cheap for all does bulbs ? thought it was going to be £5-£6 to run with 10x100 watt bulbs

thankyou for the reply :-)

i'm still confused ...... so that means that if my electricity is say 12 a unit and i have 20 x 100 watt bulbs and i use it for 20 mins it'll cost me under a £1 or around that mark ! That still doesn't seem right ? ......... someone convince me, please !!!!!! :-( !!!

yes it will cost about 11p per hour to run.
based on my tariff.

20 x 100 watts = 2000W = 2 kW.

At 12p per Kw/hr it costs 12p to run 1 kW for an hour

So 24p for an hour at 2 kW

So 8p for 2 kW for 20 mins

or how much will it cost to cause skin cancer?

To get skin cancer, the cost will work out at about the same as running the sun bed.

Not quite. You will have to add the £100's it costs to buy the machine that gives you skin cancer.

At those prices, a one bar electric fire (1,000W) for an hour would cost £5-£6! Would you really expect to pay that much for your electricity?
