£40 a year saved over a 100w incandecent bulb
so your choice really change 10 bulbs and have a holiday every year for nothing
Where do you holiday? I spent that on a barbeque last weekend and I'm poor and working class.
10x£40= £400= butlins camping or end off season abroad
any way the point is the savings can be far greater than some people think
Or you could turn the lights off and save even more! TWO weeks in Butlitz!
