Any modern Casanova looking for a suave way to dim the lights should check out the networked dimmable LED light bulb by Insteon. The 8W LED bulb supposedly glows at the same intensity as a 60W to 100W incandescent shiner, and costs a somewhat reasonable $29.99.
The real draw of the bulb is the capability to control it with any iOS or Android smartphone/tablet, but unfortunately, one must also purchase a $99 Insteon SmartLinc wall hub to make that functionality work. Affluent home automation experts can also manage the LED bulb with a $299 ISY994i controller. I guess to get "green," one must pay a pretty penny upfront to save in the long run.
