I think that has to be a CYA like electronic equipment turned off on 
I've been flying for years with ham rigs on board, and we've had CFLs 
for several.
I've never had the rigs bother the nav or com receivers. Likewise with 
CFLs, I've never heard them on any of the rigs, be they in the house or 
out in the shop. I had a few premature failures on the CFLs, but overall 
they really do last much longer and have reached the point where they 
are about on par for cost with incandescents. (energy used Vs original 

As soon as the LEDs become plentiful and less expensive I expect we'll 
see people switching to them.
Then we'll save substantial power and get rid of the mercury.
