This program that will let you send any color to your Philips Hue lamp. Plus it will let you browse to a folder with music files and it will let you change the color of the lamp in time with the music as it plays. I've also measured the spectrum of the lamp with my Ocean Optics spectrometer, and an accurate spectrum of the emitted light is displayed as the light color changes. Uses JSON to communicate with the lamp. See http://www2.meethue.com for info on the Hue device.
