[RFI] LED lighting

Well I visited the neighbor yesterday. The above link is very similar , 
if not exactly, to what he has. He said they were Cree brand panels and 
that he thought they were 8 watts. I can only find 6 and 9 watt versions 
so he may be mistaken. He said he ordered them online but was unsure 
from where. He is an industrial electrician and I am guessing he ordered 
them through work. I hope he can find out from where when he goes to 
work on Monday.

He was a hard read.  I couldn't tell if he gave a damn or not. I did 
take the VX6R over there and we were able to get the RFI to come and go 
while switching the lights on and off. He did come to my shack and was 
amazed at how loud the RFI was.

Anyone have any experience with these type of lights?
