I’ve got 3 Kessil ap9x ‘s for 300 gallon reef. I love the lights. I clean them often but they still give me overheating issues and are quite a pain in the umm neck…. They stop working after about two years. With the amount of money I have spent I expect them to live longer. Before these I had Kessil ap700. Again great light but the brains behind them not so much. Out of 3 light they die one after another. Any suggestions for my next go around?
