I think a very good report is can be found following this link: http://randd.defra.gov.uk/Document.aspx?Document=EV0429_8060_FRP.pdf
Almost every aspect is studied there and analysis is very thorough.

My vision “through crystal ball” is that organic leds will be more successful than leds in the future.

How does the efficiency of ‘energy saving’ bulbs compare with incandescent bulbs in terms of conversion of electrical energy into light + heat? The reason I ask is that sitting here in the British winter it occurs to me that any heat generated as a by-product of lighting this room is not necessarily wasted energy, and my overall energy consumption may not be significantly affected by swapping light-bulbs. Am I right?

Well while pondering on the given information we find both plus and the minus of the element yet the plus is more . most imp thing is the change . we must accept and adjust accordingly. not bad atall.

I believe most people see CFL’s as a short term solution as a lighting source until solid state lighting (LED’s etc) reaches full maturity.
SSL lighting meets and exceeds the two advantages of CFL lighting you state above, that is efficiency and potential lifetime.
Efficiencies in SSL are still steadily increasing and prices will ’steadily’ decrease as demand increases.
Harmonics can still be an issue but sensible driver circuits can largely overcome this. SSL’s are dimmable, non-toxic and more ‘rugged’ than any other light source. The question I have is how long before CFL lamps go the way of incandescents and are banned as well?. Would suggest it won’t be that long!

Energy efficient light bulbs are the easiest first step consumers and businesses can take towards reducing their energy consumption. Products have gotten light years better in the past few years and, in my eyes, indisputably better for 99% of applications. Both CFL and LED light bulbs run much cooler than incandescent bulbs, use energy much more efficiently, and do offer saving on your electricity bill. I am a vendor of energy efficient bulbs, so perhaps I am a bit biased, but I don't know why everyone doesn't switch today.

Rumora:

I have sucessfully specified 2700K fluorescent lamps and CFL’s for clients that required an “incandescent look”, mostly in nursing homes here in the States. Interestingly enough you can also specify 2700K for LED cove lighting applications!

Timothy Thiele:

You can now get “instant on” CFL lamps that require no warm up. Phillips Amalgram (SP?) is one brand that comes to mind. My wife just bought some for our bathroom and they work great.

Indeed, CFLs like all fluorescent tubes do not produce a warm and colourful light as incandescent bulbs. But as far as I know, there is no acknowledged consequence on the health of our eyes. This is only a question of comfort.
Some old technology tubes may produce flicker (rapid fluctuation of light intensity), but this is totally solved with electronic ballasts included in CFLs or associated with recent technology tubes.
