You wouldn't happen to know the Ikea part number for those bulbs, would you?  I live far from an Ikea store, but my brother will be making a trip there soon enough and could get me some of the bulbs if I had the specifics he'd need to find them.

Ikea has these. We're using them in the kid's reading lamps (a LOT less hot than haolgen!)

Its true Bruno as people buy more and more of this type of device the price will come down my only worry would be in the realm of planned obsolescence where manufacturers will be reluctant to produce products containing these components with their current long life spans, after all its very difficult to sell lots of bulbs if each one lasts in excess of 10 years. Also I've worked in this industry and I know the electronics giants intend to suck every ounce of life out of current technologies before retiring them no matter what the cost is to the consumer or the environment. I know products exist (Fiber optics, GaAs Hexagonal LEDs, Sun tunnels etc.) that could revolutionize how we light our homes but demand is not there because the average person does not know about them and so does not demand them. I hope this is changing and hopefully Curbly can help to raise awareness. Also thanks for the NPR link.

My understanding is that as LED lighting options come down in price, they're going to totally revolutionize the lighting market. Here's a good story I heard on NPR about the topic.

That's exactly the kind of bulb I'm looking for!  My whole house uses compact fluorescents, with the exception of the fixture in one hallway.  It uses halogen bulbs and they generate so much heat they feel like lasers.  I've been toying with the idea of replacing the whole fixture with something that can use a CFL, but those LED replacement bulbs might be a better option.
