Ordinary lightbulbs can be made efficient, cheaply ...
Couldn't be ar5ed to find the last lightbulb thread so will start a new one. Just seen this Boffins: Ordinary lightbulbs can be made efficient, cheaply ? The Register
"... The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb. Despite the incredible intensity involved, the femtosecond laser can be powered by a simple wall outlet, meaning that when the process is refined, implementing it to augment regular light bulbs should be relatively simple ..."
Just goes to prove that politicians should stay the hell out of mandating *specific* technology onto us. Hope this idea goes into production and we get the politicians having to argue why we *have* to keep those awful fluorescents .....

Sounds like a major result if it's true... no nasty chemicals, no long warm-up and hopefully no nasty flicker either. I wonder if the quality of light matches a conventional bulb?
They still don't sound that efficient, though, compared to CCFL and LED alternatives. I'd guess that alone will see them killed off for no better reason than petty politics

There was a thread on LED bulbs a while ago, though having read it I was left feeling that it could be a while before they're really bright enough to be a viable replacement for halogen bulbs. They're made in the sizes that fit downlighters and 'eyeball' fittings.
