Image Engineering announces a tunable light source, the iQ-LED. The new source is composed of 22 different software controlled LED channels it is possible to generate the spectrum of standard light sources such as D50, D55, D65, A, B, C etc. with a very high accuracy:

with light set D65
I've always greatly enjoyed that the peak of human sensitivity is a dead zone when it comes to LEDs!
