Might get one to put in the light on Sophie's headboard because she won't sleep without a light and it's too bright. A dim LED would be good and cheap.

There are a lot of very, very bright LEDs in production now that are painful to look at and chuck out a STUPID amount of lighting..Luxeon Stars are a good example. Spot lighting is very possible..360 degree LEDs aren't common. I've got some chrome "nut fitting" white ones for the car, that are going in the boot and under the bonnet to floodlight that, and save me farting about in the dark. They're far too bright to look into. I'd say LEDs are more a "task light" at the moment..but there's a lot of very interesting stuff going on in that area. I've seen LED floodlamps, LED PIR night security lamps and so on in mainstream shops now..it's getting there. The nice thing about LED security lighting is it's a low voltage job, and you can pick up solar powered "no running cost" units quite cheaply. http://www.usatoday.com/tech/news/techinnovations/2005-04-14-led-lighting_x.htm http://www.reuk.co.uk/LED-Spotlights.htm Maybe…but bear in mind LEDs are a very focussed light.

The brightest white LED I could find was 9 luminere so that's about 50 to give the same light as a 100w light bulb. That's £71.33 from RS Components. Add to that the cost of a bayonet cap, which I can't seem to find anywhere to buy and then the cost of a reflector and a diffuser and you're probably looking at closer to £80 to make your own LED light bulb with the same brightness of a 100w light bulb. And that's at cost price. I phoned a company to ask where I could get some LED bulbs brighter than a 20w bulb and they said you can't. Looks like LED bulbs aren't the immediate future.

This one is a reading lamp really. Not bright enough to contest with a CFL, but bright enough to see by. However, it's an old one in LED terms..the tech involved has advanced in leaps and bounds since! http://www.ultraleds.co.uk/ That's the site I tend to use, but more and more people are pushing LEDs now..CFLs contain mercury (as do all flourescent lamps), and from all I've read, they're only regarded as a stopgap measure before LEDs really come of age. Assuming one day we can afford to buy a place, I'm really going to go to town on the electrics.. I've already done it on the car...LEDs ahoy there. If you want some decent, cheap CFLs, ours came from Tesco..a few quid at most. The ones we use are ES base (cheers landlord for that damn silly fitting), but they do BC as well. 11watt CFLs are seemingly equivalent to anything from 55-100watt incandescents..there's arguing going on..heh. It helps that we've got MENTAL lightshades..I'll try to get a pic. It's like a big silver UFO..very effective though. Ooh, now you’re asking. This one is a reading lamp really.

Sophie won't go in the downstairs bathroom now because "it's light and still dark in here". They're awful! The LED light bulbs sound good though, what candle power do they go up to?
