Alan--
I just posted my note about the RFI warning on the Sam's Clubs LEDs
before seeing your note. I wonder what the differences are in these
lights since the ones I saw were 40 watt rather than 45 watt and were
in a 3-pack rather than a 2-pack.
Almost wish I would have spent the money to see if the RFI warning
was "real" or just a CYA for the legal dept.
The bulbs I saw were "Lights of America" brand, BTW.
