    Sure. You can run more than one of them by dividing the time. Of course they will not be as bright. The total light output will be the same as running just one.

    Tell us in. more detail what you are trying to do.

    LEDs have a maximum allowed continuous current rating and a peak current rating that is much higher. You can increase the current in the multiplex pulses so the brightness is almost like continuous.
