A system for generating light flux including a lamp. The lamp having a plurality of light sources for illuminating an area. The light sources include a plurality of light-generating mechanisms at least one of which is different from the remainder. At least one of the light-generating mechanisms includes at least one of a fluorescent light source or an LED light source and at least one of the plurality of light sources having a different color temperature output than another one of the plurality of light sources. A light source controller electrically coupled with the light sources and electrically coupled to a biological spectrum setting to control the color temperature output of the light sources by applying a percentage allocation of each of the light sources. A switch electrically coupled between the lamp and a power supply and arranged to control supply of power to the lamp.
