    I thought it was facinating how well I've seen identical Led's even
    up the voltage current spread. I have made two arrays. One of 16
    small Led's, and one of 9 5 watt Led's. The last one is 45 watts.
    One inch square. I can see how the high current can equalize through
    the wiring drawing over 2 amps, but with the little Led's, it partly amazing
    how well matched they are. I suppose different runs might have problems.

    My orginal thoughts were looking at these Led's varying a very slow control voltage
    from extinction to full brightness. However, I'm going to try
    and pulse 3 amps into these 3 by 3 matrix Led's, 65 watts, at a very high square wave frequency,
    something like 10 kHz. I don't know if the speed will affect the voltage and current spread.
