I have a good friend who used to (a couple of years back) work for Lutron 
writing software, but over in engineering.  There is/was a known problem with 
the plastic on the Diva lamps of a certain era, so you might have been able to 
get a replacement.

That said, he says they are VERY VERY EMI/FRI aware, in BOTH directions 
(emissions and susceptibility).  Says they have a bunch of RFI carts that are 
used to both test new designs, AND submit new designs and production samples to 
RFI!  Says they have gone around the country recording RFI and then submitting 
their dimmers to recreations, to make sure they hold up.  What he said is they 
have found that making them not fail to anything they can throw at them tends 
to also make them very rfi quiet
