Ok the mh's that i have are old and i need new ones. It seems that my mh's get extremly hot. So my question is , is there some mh bulbs that do not put out as much heat as others, or are they all about the same?? If there are some bulbs known for not putting out as much heat as others, then what is the brand. Also if you had the choice between 15k and 20k which one and why , I dont really understand the whole "k" thing. Thanks
