I agree that LED light bulbs appear to be the future of indoor lighting, but it will be quite a while until they get bright enough to be a good replacements for most household lighting. Right now they are still pretty dim bulbs. The links you have for LED go to Crane store who charges almost $40 for one bulb. If you want to try some at about half the cost you can find them at www.shop.donsgreenstore.com for a very comprable product.
