Abstract: A natural light metering and augmentation device for maintaining at least a predetermined minimum level of illumination in a building area. Broadly, the device comprises a skylight, a light sensor, an artificial light source, and a control circuit. The skylight is positioned to receive natural light and to discharge the natural light into the building area. The light sensor is capable of sensing the level of natural light received into the skylight and of outputting a signal indicative of the level of natural light received into the skylight. The artificial light source is provided with a variable light level output. The artificial light source is positioned to selectively discharge artificial light into the building area.
