Im after some help for a reef aquarium LED add on.
Im currently using 12v to a TC420, a 5 channel PWM/Timmer to dim on and off a array of LED's that are in a T5/LED fixture on 2 channels that are already current limited in the fixture.
It uses a constant positive and is PWM controlled through the negative side.
I want to add 4x 10w leds of 2 diffrent colours rated at 1000mA but i need them to be current limited after the PWM TC420 and run them on 500-600mA of current so i can use a heatsink without a fan.
What would the best way of doing this?
Make a circuit or buy something off say aliexpress?
