Hello! I am currently building an LED fixture for my 5 gallon saltwater fish tank. I have experience in electronics, but engineering something is a little new to me.
I have 6 leds, each has a max voltage of 3.4v and I want them run at 650mah. The supply voltage is a DC power adapter of 24v at 2amps. These LEDS will be ran in series.
Total voltage of the LEDs is 20.5v. What size resistor do I need to lower the supply to spread 650mah through each LED. This is ran in series, so current is constant, correct? According to my calculations I need a 32ohm resistor. Can someone help me out?
