This prototype runs by a refrigerator timer motor and takes about 1 1/2 minutes for a complete revolution. I have noticed that rocks at low tide that are out of the water, but remain wet grow much more algae than rocks that stay submerged all the time. I am using that principal for this device to see if it grows more algae then my algae trough.
It is lit with 18 LEDs that are about 1/2" from the belt which is cotton cloth on a plastic screen which is simple to remove.
If it works well I will build a much larger one to replace my algae trough.
