djmx2002 Posted January 17, 2014 Share Posted January 17, 2014 Hi Guys, I am getting ready to place a pretty big order... for my 265g tank. it's 84x30 24" high. I was thinking of getting 5 units, placing each one on a 6" heat sink, does that one come with the fan by the way? currently I got a 48v 7.2amp 350 watt power supply. would one be able to drive all 5? also can i put two chips on one driver since each channel only draws 18v max?

jedimasterben Posted January 18, 2014 Share Posted January 18, 2014 The 5.2 won't cover a 30" width. Ideally you'd need two rows of them, or supplement with other LEDs along the front and back. Link to comment
djmx2002 Posted January 18, 2014 Author Share Posted January 18, 2014 Yep I know, I want to try to keep the the aquarium sides on the dimmer side. I will most likely add supplemental LEDs if I decide to place corals closer Link to comment
jedimasterben Posted January 18, 2014 Share Posted January 18, 2014 To be honest, without a lens and at 30" depth, PAR is going to be fairly low on-axis (the Lumia 5.1 does around 90 PAR at 24" depth on-axis without a lens). As you start moving off-axis, it will get lower very quickly. Link to comment
djmx2002 Posted January 19, 2014 Author Share Posted January 19, 2014 I actually tried out the 80degree lens with the 5.1, it broke out the lights,each corner of the tank had a different color, was i doing something wrong? The tank depth is 24", planning to place the chip about 12" above the water. Link to comment
