Philips has produced a beautiful LED lamp in its LivingColor line of cool stuff. Four high output LED’s make up the source – two red, one blue, and one green. Philips designed this fixture with a color picking remote, complete with intensity and chroma controls.
It’s certainly not cheap, but it’s not unreachable. I couldn’t find a US price, but it’s £99.95 in London. So what, that’s about $1200 US dollars?
