Hey everyone\r\n\r\nI am about to replace myu MH bulb. I was wanting some opinions on temp range. I have always enjoyed the blueness of a 20K but enjoy the crispness of a 10K\r\n\r\nI'm going off the suggestion of Brandon and going to most likely use Champion lighting and get Aqua Medic.\r\n\r\nI also thought either a 14 or 15K would give me the best of both worlds. I need some feedback. \r\n\r\nWhat is going on now is that my 10K is faulty ( flickering, fading in and out, turning off ) and my 20K has a broken insulator on one end. So, I need to replace this asap.\r\n\r\nQuick question: How safe is it to run a MH bulb without the insulator? Probably not very?
