Led Christmas Lights....

[butterfly.]

How much does it cost approx, per led christmas light bulb per hour?
Thanks

so little it's not worth bothering about.

I'm probably spending more replying to you than you will expend on a single bulb......

....they're not bulbs, they are light-emitting diodes and use hardly any power at all. Probably a few pence for the whole Christmas period, if that!

[gingejbee]

....and that's the whole set of hundreds of them, btw.

I know they are not 'bulbs' but I couldn't be arsed splitting the difference :-)

Based upon a 70 light string consuming 4 watts (which is quoted on Wikipedia and seems to be largely supported elsewhere), each LED uses 4/70W = 0.05714 W.

So, over an hour, each LED uses 0.00005714 kWh. If (taking the figures from a recent electricity bill) we assume that electricity is charged at 12.744p per kWh (+ 5% VAT) that makes the cost of running 1 LED = 0.00076464p or "less than one thousandth of a penny" or to use Z-M's much better answer "so little it's not worth bothering about"!
