as for the Hamilton units... for $499 - you can get a 6x54 ATI Sunpower with all ATI bulbs. Only difference is they have no moonlights. (from ReefGeek.com) Hamilton unit comes with their own bulbs which are probably not all that great in comparison to ATI, KZ, etc.

ATI actually manages heat in their unit - they just don't throw fans on it and call it a day. Their are channels to cool the label end of the bulb and the cover keeps bulbs and ballast operating at the right temp. Too cold and you lose output, too hot and you lose output/longevity. There is a fine balance.

The reason the Powermodules have more fans than the Sunpowers is because of how compact the Powermodule is. The Sunpower is more open so it can manage the same thermal load with fewer fans. Difference in par is only 5%. Both are made of the materials and contain the same ballasts. Sort of like buying a Honda Civic or its Acura counterpart.

where do you get 499?...also, no LED moonlights on this fixture.

When I was looking for gear about 5 months ago I was referred to this chart for T5 lighting.......I ended up with 4X36" Hagen GLO based on this chart....they aren't bad but I'm starting to wish that I joined Canreef a little earlier so I could've seen threads like this one before buying.
