Hello SaltyFilmFolks. Thank you for the info and I am thinking of a 40 gallon breeder at this time. I would be ordering a least two to help with an even light spread in the tank. I will be upgrading to a much larger tank in the future (150 or bigger) and that is also driving the selection of this light fixture. I would love to use Kessils (360s or AP700) or perhaps a Radion G4, but I am not willing to spend so much money on a fixture that has a 1 year warranty. The marine version of the Cannon Pro can be purchased at Aquatic Warehouse (link below) for $665 - and I think the extra money spent on the cannon has several benefits when compared to the Kessil and Radion:
-5 year warranty
-No moving parts/no noise and IP65 water resistance rating
-Multiple beam angle selections to accomodate shallow or deep tanks
-High efficiency with pulse-width modulation (PWM)
-Spectrum has amazing coverage
-Single light source/multi-chip LED, so shimmer will be amazing along with color blending to avoid disco effect
-Remote and controller included
