OK to switch Luxeon LEDs "downstream" of the BuckPuck?

    I note that the Buckpuck LED driver datasheet only shows strobe type switching being accomplished by inputs on the control wires of the 6 wire drivers. I have the 4 wire driver and am considering using FETs (on the output side) to switch respective LEDs. But other information suggests such "hot switching" can result in damaging current surges. Would a capacitor help by absorbing the spikes? Or I could make the LEDs flash simultaneously and place the switching on the power input side of the driver.
    This is the datasheet for the Buckpuck driver http://www.luxdrive.com/content/3021-BuckPuck.pdf
