I hate math. It’s really no fun. But when setting up LED lighting you just have to do it. What a a pain. Sometimes I just write hear to sort out my thoughts.

Okay, so my 65G tank has a 225 LED board and a 132 LED strip. Each so the board is 4.5 amps, and strip 2.54 amps. Just to be safe I’ll drop a 12v 6a adapter on the board, and a 12v 4a adapter on the strip. That ensures I’m not maxing out the adapters and only getting close by 80%. Do I need a 20% gap? Probably better not to burn my house down.

Testing for me has concluded 63 LEDs should be enough to light up a 15.5″x cube. That’s 1.26 amps.

The top elongated cube will have only 42 LEDs in the strip, but 45 LEDs as G4 spot lights, totaling 87, making 1.74 amps.

I’m assuming I’ll be dropping these on separate 12v 6a adapters, with a maximum of 4.8 amps on each.

2 cubes and 1 elongated cube will be 4.26 amps. That’s got a pretty good safty gap to 6a, needing 6 12v adapters

Above all the tanks I plan to take some of my 6500K LEDs and leave them there for plant lighting. Each one is 96 LEDs. So 1.92 amps. Augh. At the moment not sure I even want to bother.
