I paid well over $20 (in today’s dollars) for my first CFL and now you can buy much better ones for under $1.

They are actually heaters that happen to produce a little bit of light…

Thank you for the article on LED’s. I hope we figure out a way to make them much less expensive – I’m okay with spending $20 on a bulb that I know will last 25,000 hours and uses less than 1/6th the energy to produce great quality light – but it sure would be great to be able to buy it for under $10.
