I have an odd situation. I have a PD-6WCL controlling a series of wall sconces in my home theater. Each sconce has a 60W equivalent G.E. Reveal LED. When the device is controlling all eight bulbs, they flicker/pulse at any dim level below 70%. Above that dim level the pulse is hard to distinguish, and completely gone at 100%. If I unscrew even one bulb (doesn't matter which one, so it's not a bad bulb) so that the dimmer is only controlling seven bulbs the system works and dims down to 1% without issue. The total wattage of the eight bulbs is within the specs of the dimmer even with the derating, so it surprises me that the breaking point is the 8th bulb. Any ideas?
