In one aspect, the present disclosure relates to a method for modulating a light source in a light based positioning system, the method comprising selecting a modulation scheme for the light source, wherein the modulation scheme periodically varies an output of the light source from a peak output level to a bottom output level; adding a DC bias to the modulation scheme; applying the modulation scheme with the DC bias to the light source, wherein the DC bias reduces a required power for the peak output level to achieve a given luminous output by increasing the bottom output level of the modulation scheme, and an average power of the light source when modulated is equal to an average power of the light source to achieve the given luminous output without application of the modulation scheme.
