You have over five kilowatts of christmas lights ?!

Each hour the lights will use 5.585 KWhrs Multiply this by 14.5 pence and you have your hourly figure.
5585w! That's 5 and a half bars on an electric fire. Sorry but have to know, are you asking on behalf of the City of Westminster in readiness for wiring up Oxford Street this year?
What a lot of light!
5585W = 5.585KW
5.585 x 14.5 p = your cost per hour. (About 81p per hour)

No it's the total wattage of lights in a village centre lol! Made up of

Braid Lights 15 x 115w = 1725

Stalactites 8 x 150w = 1200

Ceilings of Light 14 x 190w = 2660

Total wattage = 5585


The sum will be 5.585 X 14.5 = 81p per hour
if you want a breakdown of consumption ... or just feel curious
B&Q do an energy monitor for about �10.00
you can enter the tariff ... it gives you the cost

Thanks ACtheTroll that's a good idea - the lights are connected to individual businesses and the Business Partnership refunds what ever is used but there is always a dispute, that would solve the problem.
