LED Color rendering
February 26, 2011
A quick and half-assed comparison, inspired by an argument on SlashDot.
I took (more than) five pictures, of my hand, holding a bunch of different colored wires, in indirect daylight, under neutral, cool, and warm LEDs, and under the light of all three LEDs combined. Camera was Canon SX100IS, ISO 100, Cloudy white balance, let the camera pick aperture and shutter.
Executive summary: true daylight is best of all, then mixed LEDs, then neutral, then you’re probably not happy with your light.
