I'd like to know if anyone has had any good luck with these bulbs. I did purchase 6 total of these, 3 14K and 3 20K. They actually look nice but the coral (SPS) don't seem to like them. I'd like to know if anyone has had luck with these.

Update - I've replaced the no name MH bulbs with XM 400w 10k bulbs and you get what you pay for. With the cheaper bulbs corals were bleaching and dying and now with the X10 bulbs they are coloring up and the polyps are coming out again. I thought one of the corals died as there was little to no color and all the polyps were drawn leaving only the skeleton. Lesson learned, no cutting corners on lighting for me.
