I can control the heat on a 150w HPS better than I can control the heat of 134w of CFLs [ in two spectrums; (2x 42) warm white and (2x 25) in daylight ]. Simply because I'm focusing my fan's energy on a single bulb [ well, in my case since my HPS is a floodlight; the housing ] and not on multiple lights. Not only that, it was slightly more space conservative -- one quality I always looked for in lights for my relatively small grow spaces. Hope this helped.
