Hello,
I'm currently planning to build a high power LED array that can be dimmed using an arduino. The LEDs will be used to light an aquarium. This project is on a budget so I'm looking to buy some cheap LEDs on ebay, as well as a constant current LED driver that supports PWM.
I think I have that all figured out. I just have to make sure that the combined forward voltages of the LEDs don't exceed the output voltage of the driver?
The one thing I'm a bit stuck on now is what power supply I should choose. The LED driver accepts input between 5-35V.
So I'm guessing I need an AC-DC converter that doesn't output more than 35V? Also, does the amount of output amps matter?
Thanks in advance!
