I sprang for one of the $40 lightbulbs (I do audio recording and needed a bulb that wasn't hot and wouldn't make a buzzing noise like the fluorescent ones do), and it's been great. It's supposed to last for 20 years. I'll get back to you in a couple of decades if it did, but I read an article that said that lightbulbs may reach a point where they last so long that they are something people take with them when they move homes, like furniture.
It seems crazy to think of a time when people might buy just a few lightbulbs in their lives, but it'd be great for reducing landfill.
