I have two light circuits in the basement - one with 5 lights, the other with 3. The lights being used are Philips R20 LEDs (9290002192). The compatibility list for these lights is here: http://www.lighting.philips.com/pwc_...tage-Lamps.pdf
Initially, I bought two Lutron CTCL-153P dimmers. They work fine, but the LEDs all buzz. As soon as I tried switching the dimmer out for a simple switch, no more buzzing.
Initial research brought me to this forum, where the folks from Lutron seem to recommend ELV dimmers. So I picked up a SELV-300P and hooked it up (Power runs to the light switch box first, so there is a neutral available). Now, no more buzzing, but dimming seems to be quite finicky - at one point around 75% power, I get a very noticeable flicker from the lights, and there isn't really a change in light output except over a very small range when the dimmer is almost all the way off.
Any ideas? Is this normal for ELV dimmers?
