Just a question, I was looking at a plug n play 400 wt HPS. I believe itwas Sun System 2??? ... my local hydro dealer was giving me the sales pitch about how you can change HPS and MH bulbs. and also that it supports a 600 wt bulb. THE QUESTION... the system has an enclosed ballast. when putting my hand directly under the system it didn't seem to produce alot of heat but Im curious of anyone who has or has tried them... DO they produce as much heat as I think it would???? Curious because i was looking into grabbing one. right now in my 2x4x5 I'm running about a total of 375 watts of CFLs... would the HPS be WAY hotter than all those cfls,??
