I have a friend who purchased the 44e for his 40gal breeder ... if the light is above the fixture high enough it will cover the tank. Me personally would have went with 2 units. I believe these units cover a 24x24 area. I have to Lumentek pro 120's on my 48" (75gal) DT and they light my tank up beautifully.
Thank you! Do you know what kind of PAR you are getting to the sand bed with your lights on your 75gal? I'm thinking about upgrading to LED's over my 48" 90gal.
