I went to the Cree Web page where I found the below link:

FAQ


The link does NOT go to a FAQ on RFI.

Drilling down and clicking on another link 
http://www.cree.com/lighting/document-library , I waited a couple of 
minutes and gave up without a connection.

Elsewhere, at 
http://www.energystar.gov/products/specs/sites/products/files/CREE_0.pdf 
I find a letter from Cree indicating that they did not agree with the 
EPA that refernence to FCC compliance should be removed from their 
documention (signed byTim Henning, Specialized Testing Manager | ENERGY 
STAR Program Manager) and a document at
http://www.cree.com/~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/XLamp%20Reference%20Designs/XLampXPE_MR16_Ref.pdf 
does include the following statement:

*electromagnetic and radio **Must meet appropriate **FCC**requirements 
for consumer use (FCC 47 CFR Part 15)****
****frequency interference***

Poking around a bit more... are these lights DIMMABLE?

/Lumenpulse receives US patent /

/The patent, the first of seven pending for the company's Lumentalk^(TM) 
technology, provides a method of intuitively reading a traditional 
analog TRIAC dimmer in a digital fashion, which enables digital control 
of LED lighting over existing AC power lines, to maximize cost and 
energy savings. //

//The Lumentalk technology turns existing electrical wiring into a 
stable, noise-free high-speed communications link for data, enabling LED 
fixtures to be reliably controlled without additional wiring. The

 From Lumenpulse:
"With Lumentalk technology, LED fixtures can be dimmed and controlled 
over existing power lines. It works with any control or dimming standard 
(Triac, ELV, 0-10V, DALI, or DMX), AC voltage (100VAC - 277VAC), and 
operates within frequency bands allocated by worldwide regulations (FCC, 
CENELEC, ARIB)."

As if we didn't have enough trouble.
