I went today to buy some lights for our Xmas tree and came back with a Philips LivingColors, a beautiful lamp with high-power LEDs which combine to produce any color in the spectrum, controlled wirelessly with an Apple-style remote. Here's our 60-second video review.
The Philips LivingColors LED Lamp is $215 in Europe, which probably will be less when it reaches the United States next year. While it may seem expensive, the LivingColors has a 100,000-hour lifespan thanks to the use of LEDs and consumes a lot less than comparable incandescent lights, which obviously can't produce the same kind of lighting (in addition, it's not hot to the touch. It's so cool that kids can touch it and probably lick it without risks.) So in the long run, and coupled with its design and wireless remote, the price is absolutely reasonable.
The LivingColors lamp is absolutely worth it if you are into lights (which obviously we are), with amazing controls, elegant design (the metal interior inside the clear bubble is fantastic) and awesome hues. If you are looking for an ambient light to your home or office, I highly recommend it. [Philips]
