One thing I have been wondering is when you dim a led light does it us less wattage or does it still use the same wattage and dissipate the extra power?
The can LED lights I have make no noise at all when you dim them. I have one on a very old fashion rotary dimmer and it still does not make noise.
looks like they are closing them out
