Hello.

I was hoping to get some help with a small project I'm working on.

I need to string together 50 LED's in a parallel circuit.

The spec on the LED's are as follows: "Forward Voltage: 3.2v - 3.8v. Forward Current: 20mA (typical), 30mA (max)".

As I'm not particularly technical, I'd really appreciate it if some kind soul could give me some indication of how much power I'd need to run my circuit.

Many thanks in advance.

Hi

There is a LED calculator at this site

The usual way of calculating power is volts times amps equals watts.

I'd really appreciate it if some kind soul could give me some indication of how much power I'd need to run my circuit.

About 3.5 Watts (3.5V @ 20mA x 50)

Thanks all! Much appreciated!
