I was interested to see how much those on here thought they were

anything good to say about CFL.

In my case, I would guess about £250 / year saving.

Interesting, John. You're the only one who has put a figure on it. Since
so many on here are very keen on any sort of energy saving lights, I
thought they'd all have some figures to hand.

Its not always straight forward to calculate the savings to be fair. In
my case I have a spreadsheet of all the meter readings over the
years[1], and have also annotated it in places with notable events (like
the boiler swap, or when LED lamps started being used). So in the case
of electricity use, I can see about 5 kWh reduction in the running daily
average. Not all of that will be lighting, but a fair amount will be.

[1] and it includes calculations to work out the average current, and
average consumption per day since the last reading etc.
