what dimmer switch can I use with Luxeon k2's

[Jbcourt]

I want to adjust (dim) the voltage to 20 Luxeon k2 LED's. They will be running at 3.6v 750ma in a parallel series aray. 10 blues in a series 10 reds in a series wired in parallel to a 19.5v DC supply. I would like some help picking the right controller for this.

hi, maybe this could help.. Although I wasn't really an expert in everything,
but maybe you could give it a try...

The LuxStrip light engine provides reliable light from 6 cool white, Luxeon K2 LEDs that are powered from a single LuxDrive Buckpuck Driver.

For this to work, the Vf (forward voltage) of the red and blue LEDs should be the same. Look for a boost driver that has a minimum output of 36V and 1.5A. Also, your 19.5V supply should have >3.5A output.

added: the maximum input voltage of the driver should be >19.5V.
