You decide on this one.
Audio Bulbs represents one of the best ideas of 2011 - they're a combination of speaker/light bulb. You screw them into any lamp or ceiling fixture and suddenly you have yourself a wireless sound system in your home or office. There's a transmitter for your sound source and for controlling the dimming level of these LED bulbs.
I was originally thinking of getting several of these bulbs for the family room but at $300 each I had to rethink my strategy.
