[Avid-L2] Phillips Hue lights for a monitor backlight?

In my recent DolbyVision mastering class it was mentioned that the Phillips Hue Bulbs can be adjusted to proper color temperature for a monitor back light.  It says in the various info I've obtained that the White Ambience Bulb is controlled by blue tooth and it can have a color temp of 27002K to 6500K.  I picked up a couple lights and got them working.  The interface on my new iPhone, yes I finally retired the BlackBerry Torch, and I can swing the color temp but the interface is not set up with a degree Kelvin parameter.  It's either choose a preset or move the icon in a circle with the bottom going more blue white.  I'm assuming the bottom of the circle would be approx 6500K.

Anybody played with these bulbs using a real color temp meter or know if there is a way to get a preset that is designed to set the bulbs to 6500K white.

They also have dimming and I'm wondering it the dimming would effect color temp.  I know it did on tungsten lamps on the stage.
