Even with filters, occasionally, one of my lights will cycle. FUN in the middle of the night (in our master bedroom). I use it for heat (this is double protected, as the heater also has a controller) and for my fans. Ca Reactor? Wow. That would make me pause... But, my reactor is on all of the time anyway - but I'm not running the heck out of it either. I SURE wish there was an easy way to manually turn all of my lights on...
