I like my Hamilton Belize MH/T5HO... I don't find the heat generated by any MH a concern, nor the overall cost to operate, and it just works. Bulbs are not costly either overall.
However, I am seeing many LED's for sale, seen may units at LFS with defective fans, lights, etc... I don't have this problem with MH, so I just stick with it for now, future you never know.
