These are 2700/5000k chips but supposedly have some w/ higher cool white..

$16/chip.. 2000 lumens 500mA at 35.5V approx..17.75W each..
Not stocked though..

Doing visible color temp mismatches w/ too much separation gives a "blotchy" rendering.

i'll look into that chip, this was a chip I was looking at though which kinda does what your saying as well. 60 watt CREE RGB WW W chip only 1 channel though

[Ebay Link Removed] Cree XP-E Multichip LED 60 Watt Red Green Blue Warm White Light 24-26V 1-2A | eBay[/url]

unclear if the Warm White is the high CRI version Cree makes or not. but I imagine with the RGB it will be fairly well covered spectrum wise.
