Here's what cybersofa had to say about low energy light bulbs on Jan 20th 2006. (It took me ages to find this, because now that the journal is in ‘memorial status’, it’s not searchable, nor can I link to the right page. What a brilliant journal it was.)
Let's make some light bulbs. Mine's got a piece of wire in a simple blown glass envelope from which I've extracted the air. You call this technology Victorian, but I call it appropriate. Yours has got two heated filaments, a load of electronics to generate a high voltage, a glass tube bent and twisted to increase surface area, filled with a rare gas, and coated with a radioactive chemical. OK, it uses less energy – er, not counting energy used in manufacture or disposal, obv. It also lasts longer – for that money, so it damn well should. It's still ugly, and it still takes nearly a second to light up after you switch it on.
I see I’ve also mentioned the subject before.
How lucky that I have a few proper bulbs stashed away.
