Check this out.
I have replaced half of my 600w HPS lights with 315w CMH over the last month. ( Loving it.... better spectrum, gooey buds)
I'm pretty impatient so I ordered the ballast / bulb conversion kits as I could afford them which meant I ordered three different times and bought three different brands, usually going for the best deal at the time. I can ended up with two of each :
Illuminati
Prism science
Galaxy
Upon firing them up they all seem fine. However, after a few days of running a them I decided to hit them with an IR temp gun and here is what I saw...
Illuminati 116degrees
Prism Science 127 degrees
Galaxy 90 degrees
Quite a difference in heat output! No a really alarming discovery, but one to consider when placing ballasts inside or outside your grow room.
Need heat? A wall of prisms would do it I suspect!
Wanna keep it cool? Then Galaxy FTW.
Plus the Galaxy is dimmable too !
Just my .02
