WyrreJ,

"Because the voltage versus current characteristics of an LED are much like any diode (that is, current approximately an exponential function of voltage), a small voltage change results in a huge change in current."

It can be done but shouldn't be done. All of the benefits of an LED go down the toilet when you try to dim them. If you feel the need to dim LEDs then you should seriously consider PWM (Pulse Width Modulation) as they react very well to that scenario. Of course the effectiveness of PWM is very dependent on the color of the LED you are using as your eye will integrate the different colors at different efficiencies.

OOOPPSS - Just looked in a mirror and saw a dweeb. Sorry 'bout that.

BTW ETL - the pix look great
