This year is the last year that you can buy 60 watt light bulbs (UK).

Dave mentioned elsewhere in the CZ the new Philips Halogen bulbs, which I've only seen on sale at B&Q.

I found an Osram equivalent here -- this is the way I will be going, once I've burned my stockpile of 60W bulbs... Frosted and clear are available.

I really see less and less point in CFLs, and the halogen energy saving replacements will be the way to go IMHO

In defense of CFL's I've found them great in leadlamps. Usually I get through 2 or 3 ordinary bulbs a day, maybe 50% fewer if I use rough service bulbs (at 4 or 5 times the price). One secondhand CFL has lasted for 6 months. Not so much heat either, so it doesnt burn your hands/wrists/head. Still has the problem that wherever you put the lamp it shines in your eyes, and not on the job, and once you have got it in a nearly acceptable place, it falls off at the most critcal phase of the job. Guess that is not the fault of the bulb (sorry lamp)!

Power LEDs are good too, but expensive at the moment. I've been making a few lights for an off grid, low voltage application, using an array of six 1Watt white LEDs. It'll light a room so you can read comfortably, and comes on to full brightness straight away, even in low temperatures. Reading the specs I think that 1W LEDs give more light output per Watt than the 5W ones.
