That will be the killer LED light. Unfortunately it is probably cost prohibitive today  |
While in theory that makes sense in reality it's not necessarily true. The kessil doesn't have the same amount of colors in the GHL so while you may think the kessil is better at color blending it's not really the same. While the pods in the GHL may look pretty basic apparently they were designed specifically for maximum color blending and efficiency.

Light distribution
A homogeneous illumination is as important as a high light performance. Our engineers determined the best possible arrangement of the LEDs and design of the reflectors through extensive computer simulations and practice tests. With the goal to achieve an optimized illumination the LEDs have been arranged in 2 x 3 evenly spread clusters and all LEDs in one cluster are placed with a minimal clearance to each other. Additionally the clusters had been brought to the edge of the lamp as near as possible. The results are convincing:
Ideal mixing of the single LED-colors, the light in the aquarium has no disturbing color spots
Uniform illumination over a wide area
Efficient heat dissipation over the heat sink

Also consider the spread, the kessil is pretty tight which probably aids in the blending, if you widen the optic to be more comparable to other fixtures you may lose what you've gained. The Kessil is just a multichip LED which may or may not be the way the industry will go, in the end you're still looking at different colored light sources, packing them closer together may not make a difference and only cost you more in efficiency. Cost wise multichips are available and realistically cheaper than multiple single LEDs in terms of watts/$.
