Initially I had a resistor in series with the LED to limit the current but I noticed it was not very bright. I decided to experiment and remove the resistor, connecting the LED directly to the 5V. I only measured close to 200mA passing through it, when it should be near 300mA.
The LED is sold as a 1W bead with Vf of 3.6V and 320mA current at this voltage.
