Some eople only feel good about purchasing knowing they have paid the absolute most possible for the best brand name.

If that's NOT you, have a look at these new Hamilton fixtures JL just started to carry...

literally everything on them that the stealth and power module owners have, but at 500$ bulbs in for a 48" 6 bulb unit...yes, there are 3 fans and led moonlights as well.

true - but ATI's are tried and true. Lots of documentation online that shows ATI's thermal management and reflector technology produces a more efficient unit. I couldn't anything for the Sfiligoi's.

as for the Hamilton units... for $599 - 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.
