I recently installed CE color changing (5 temperature settings) LED all-in-one fixtures in my bedrooms and have been having an odd issue. I wired four fixtures with 12/2 Romex in parallel out of a Lutron Caseta wireless dimmer, compatible with LEDs. The fixtures have a physical temperature control 5 position selector switch and we use the 3500K setting. The second light in the circuit will power on very dimly, and show a noticeable flicker. I am talking like you can barely see any light coming from it. After 30 seconds or so, it will begin to operate normally. I have changed 3 fixtures, ensured all wiring is tight, and even replaced the switch. It still persists every few cycles.
Finally, the other issue is occasionally, the second light on another will get stuck at either its lowest or highest color temperature setting, regardless of color selector position on the light upon power on. cycling power doesn't clear it but it will go back to the desired setting eventually. No clear pattern i have noticed.
The only other information I can think may be relevant is that they are fed through an AFCI outlet, and that is fed by a 20A tandem breaker. Additionally, I am getting 120.2- 120.6 VAC at the breaker and switch.
Any help or ideas would be greatly appreciated.
