Hello,
I'm not a fish guy (I think they're cool as heck, just not my hobby) I'm an electronics guy. A co-worker of mine who is a fish guy has asked me for help with an LED lighting system for his 78-gal reef tank.
His goal is to have 60 x 3W CREE LED's in this bad boy. I've built a circuit that can independently drive 4 channels of LED's anywhere from fully on (current limited to 1A) to completely off, with intensity controlled via PWM from a microcontroller. The plan is to have a 48V, 4.5A power supply driving 4 strings of 15 LED's each, and will be able to vary the strings independently via software to simulate sunrise, moonrise, or just run them in a manual mode controlled via a pot.
I know my electronics but I'm completely ignorant to tanks, and I was looking for any information or stories of people taking on similar projects in the past, in hopes I can learn about any potential pitfalls and what I should avoid. Any info would be greatly appreciated. I've searched around online but not come across anything too useful.
Take Care,
Roger
