Cost of incandescent 60 watt lightbulb

Caterina

Please can you help, I bought an industrial vintage lamp for my kitchen and the ideal lightbulb to go with it is an old style Edison incandescent 60 watt lightbulb.

Now I am getting worried that the cost of running it is going to be prohibitive. I know that LED would have been much more economical, but I really wanted the old style lighting.

My electricity provider charges just short of 15 pence per unit. How do I calculate the cost per hour of my new lightbulb?

Thank you for your help.

Halogen bulbs can look similar and are a bit cheaper to use.

A 60 watt light bulb will consume 60watts in one hour and will therefore take 1000/60 = 16.6 hours to consume 1kwh.
If you pay 15p a unit (kwh) then it will cost you just under a penny an hour to run it.
If you assume that you'll have it on for three hours a day for 365 days a year = about £10 per year. I doubt it will break the bank.


An equivalent LED lamp would take 1000/4 = 250 hours to use a unit and would cost about 66 pence a year.


Leds really score when you've got a lot of lighting such as in a kitchen with 8-10 50watt downlighters where you can be using 500watts an hour. They would cost you 7.5p an hour to run whereas 10 x 4 watt LEDs would reduce this to just over a halfpenny an hour.

Thank you for your useful replies. Everywhere in the house we have LED and other saving ones, but this is the one lamp that I really want to look good, we spent a lot in making the kitchen (the heart of the home as far as I am concerned) look lovely. And the light is dimmable, we have dimmer switch. Yeh, not breaking the bank, a small indulgence in an otherwise frugal lifestyle! I was worried it would run to goodness knows what, but a tenner a year I can afford!
