Well just about all the lights in my house have been "energy savers" for years, and now they do small ones that actually fit the shades, my wall lights are too. That's made 240w go down to 42w. The range and style of the bulbs is improving all the time.
Because I'm on my own a lot I tend to just use a 20w bulb in the standard lamp next to my chair and remember to switch other lights off when not needed. However I have to confess that in having my bathroom modernised I have gone down the halogen light route from fluorescent tube lights, and I have a halogen reading lamp at the side of my bed. But I still have 2 fluorescent tubes in my kitchen.
