    ...so bearing in mind the dark potential of the curve of diminishing £ per eco retunrs is there any reason not to just use 'normal' electrical fittings with CFLs...

    that's the unfortunate conclusion I've come to - GU10 megaman CFLs in relatively standard fittings. Would have loved to gone LED, but it's way too expensive.

    I still have a problem with calling them low energy light-bulbs

    Well they might be in themselves

    Overall in a building in the winter if there is an energy saving made in lighting input energy this exact same saving will have to be made up for with additional heating or the building will be colder

    In my house I have to use them or they overheat the house:smile:

    ...swap all the CFLs for tungsten filament at equinox Tony...?

    ...could become a little seasonal event / party

    CFL (or flourescent tube) is most cost-effective by a large margin.

    LEDs let you you do various thing you just can't do with plain bulbs with strips round covings and low-level stair lights etc. And if you are careful you do 50-100% better than CFLs on power consumption, but it will cost you...(although the premium is dropping daily and various moves are afoot to remove the need for saphire as a base material which will be a step-change in cost)

    How about designing a combined halogen & CFL bulb... When switched on the halogen element provides instant light then as the CFL warms up the halogen is dimmed automatically to maintain a constant light level.

    Come to think of it you could probably fit a matrix of both types of downlighter in your kitchen and use a sensor to dim the halogen as the CFL brightness increases.
