I was wondering if I could use the superflux 4 chip leds in place of the 5mm ones, the voltage for the red ones is still 2 volts but they use 80ma of current so not sure if the controller can handle it?

Thanks

No, the outputs are limited to 40 mA maximum. You'd also need to change the resistor, because passing 80 mA takes up more voltage than 20 mA.

It is, of course, possible to use the LED outputs to drive a transistor that switches a larger current, or even to drive solid-state relays that each control 500 W floodlights. So, this certainly isn't an absolute limitation.

Oh dear, I fear what you may have just inspired.
