The Crystal Colouriser has 3 individual LED colours, and achives a colour blend by changing the intensity of each colour. To achieve a lower intensity, the light is switched on and off rapidly ( modulated ) but at such a fast rate that it is imperceivable to the human eye.

Normal houshold lights driven straight of the mains are switched at either 50 or 60 Hz. That’s 50 or 60 times each second depending on the country you live in.

The Crystal Colouriser switches at 136.1Hz, The ‘Om’ frequency which will not be visible, but can be observed using special equipment.
