Cool white versus warm white:

Dimming with LEDs is apparently most easily achieved via PWM ( pulse width modulation ). It involves a microcontroller that rapidly switches the LED on and off ( above 200hz so the human eye can't detect the flicker ) for varying amounts of time, to decrease the effective duty cycle of the light, therefore dimming it.

Very cool! Thanks for showing us these lights MaNu!!
