Light flickers on dimmer. With my GE Z-Wave dimmer, the power gradually decreases from 0 to the last brightness level. It flickers every time you turn it on and off. This makes it distracting and useless. Hooked it up to another dimmer and it doesn't dim too low without a lot of flickering. Used another brand open filament LED that didn't have this problem. (Not sure if this is by design or because this one is 10W and the one I changed it to is 8W and there are different power requirements.
