Cree LED Bulb

Anyone know if these light bulbs allow for more predictable White Balance?

They offer 2700K and 5000K bulbs. I was hoping the 5000K bulbs would be more likely to match up with Daylight WB settings, make the AWB more consistent, or outright work by setting the Custom WB to the specified Kelvin.

I have a ShiningBeam I-mini which uses the Cree XP-G R5.

Used dimmed, it measured 4950K, but with pronounced green tint needing +47 correction.
Used fully bright, it measured 5250K, still with the pronounced tint needing +44 correction

I have 5 Cree 2700k bulbs in my dining room light. Using my WhiBal card, and the eyedropper in Lightroom, I'd say the Kelvin temp is pretty much right on. They still have a green cast, but not as much as CF. When shooting people under the Crees, I have similar flesh tone issues as under CF. I've had some success with the orange and yellow hue sliders in Lightroom but I still prefer the flesh tones I get from a flash, tungsten, or natural light.

Thanks, guys. I was hoping they'd be clean, but I suppose having low wattage bulbs that last forever in my house uniformly lighting everything up is still nicer than the alternative CCFL bulbs. Daughter is on the way, and I'd rather get the lighting uniform for easy photo ops.
