I have a love-hate relationship with my powermodule. I got it for super cheap used, its a beast of a light and great looking both color, shimmer and sleekness of the light, but the LEDs have a very high pitch tone when they are not 100% (i found out I am susceptible to high pitch frequencies) and the dimmer doesn't always change the LED program. I found a work-around, so not perfect, but better than getting a new light.
