Last year, Philips showed off their LivingColor lamps at a media event. Each compact light can illuminate 16 million unique colors, all of which can be controlled via an included wireless RF remote. You can set any remote to control up to six fixtures simultaneously, keeping their colors in synchronization for a dramatic effect. Since it uses some seriously bright LEDs, Philips designed a special heat sink into the lamp that looks more like a work of art than a technical necessity.
