I have been looking at saving money on electricity bills as I'm sure most people are. A friend told me about LED bulbs and how much cheaper they are to run. I took the plunge and bought some 5W GU10's for my kitchen and must say I was quite surprised with them.
We have one of those energy monitors and it used to jump up 3 or 4p an hour when the lights were switched on in the kitchen and now it doesn't move at all. I was a bit disappointed to start with because I thought it would make a bigger difference. Then I multiplied it up and it is about £50 a year. Plus LED bulbs should last 10 times longer so they tell me!
I have since found a calculator which is easy to use and also tells you how much C02 you save too (www.kolighting.co.uk/savings-calculator).
Thought thought it might help save some people some money like it has me.
Would be interested in other people's savings if they change especially if they have a lot of bulbs in their house!
