I'm working with a system that came with RRD-6CL dimmers for a home full of incandescent medium-base 65W floods. Some of them have 10 bulbs per on/off switch which puts it over the 600W max. I assume this means for those I should go with the RRD-10D? The owner doesn't plan on going with LEDs anytime soon but I guess the RRD-10D has less support for LED bulbs than the 6CL?
Also, in what situations would the 10ND be required? Is it safe to say that if the circuits work with 10D, the 10ND isn't required? Thanks!
