Technology is progressing at a pretty rapid rate. One promising product is the MusicLites light bulb speaker. Developed in partnership with Sylvania, these bulbs look like the kind used in overhead can lighting. Just screw them in and sync with a transmitter that plugs into a computer, stereo or mobile device. The sound plays through the lightbulbs, wherever they are in the house. It's a great concept, but there are a few drawbacks to this product in its first incarnation. The bulb looks slightly different than traditional can light bulbs, and doesn't dim in concert with the rest of the lights in the room when controlled through a wall dimmer. It can dim when using the MusicLites remote control, but it doesn't match up perfectly with the lighting level elsewhere. I had trouble syncing the system when I tried it at home. It's a great idea but not quite ready for the mass market. Audio companies know that consumers want wireless products and are developing them as quickly as possible. But achieving a quality product is a lot more difficult than we'd like. As one loudspeaker manufacturer once told me: If wireless worked well, there would be no wired products.
