i've got a 48" Hamilton retro kit in a wood DYI canopy,,,,2-400W 10K MH's and 4 -55W actinic PC's used with new bulbs from eBay,love it!
really like the neatness of the cables and the plug in's and connectors,loads better then the rats nest that could have been with others. kinda wish i had electronic ballasts,,but oh well,,i'm still happy with this system,this replaced 160 watts of normal flo's,, so myself AND the tank is happier!
