Its fine fitting halogens in the home, plenty light but when it comes to how much leccy they use its a bit staggering, so I have started updating some of my lighting, all the old incandescent bulbs were kicked out a few years ago and at present I have a mix of the mini neon economy bulbs, slow to start up as they age, and halogen, instant start but very hot. I sent for a couple of warm white LEDs to try in the bathroom where there is a direct comparison available with a couple of halogens, very impressive, almost the same light output though slightly whiter, swapping one for the shower I was disappointed as my feet and shower tray blended into a grey gloom so this one location will, for the present remain halogen lit, bearing in mind the consumption in that one room has dropped from 200w to 70w.
Now to tackle the hall, stairs and landing, in total 350w which after conversion will be 21w, with the bonus of a much longer projected bulb life. The initial outlay is quite a lot but with fuel prices shooting through the roof its as well to do it now
Main lighting in living room etc will still be the economy bulbs for the better spread of light.
