I have done some reading and they say not run dual arcs on eballasts or on dimmed setting? Is anyone running one and do they dim it or have any issues? http://forum.grasscity.com/index.php?/topic/1272388-First-grow-journal!
No, but I habe read that dual arc bulbs put out less light than a regular bulb. I googled somthing about best HID bulbs amd discovered they are not that great.
