Ok, not up with compact fluoros - or is it? How much capital cost in THEM?

Say 80p for a pendant fitting and 4 pounds for the bulb. It will have used
only 20kW/h. So the total cost over the same period would have been 4.80
capital and 1.20 in energy. It will also continue to operate for another
8000h.

Therefore, a CFL would have about half the capital cost and a fifth of the
running costs. Bulb replacement costs will be similar over a long period.
