Here is the reply: Fluorescent lighting produces more gentle, consumes less power, and lasts longer than incandescent lamps. The subject of the invention is a fixture that contains both the complete spectrum lamp and the polarized diffuser to realize 72 Watt Full Spectrum the specified results of a synthetic lighting system that has both the spectral power distribution and light polarization traits of pure daylight.

Pupil dimension is then determined by a combination of photopic and scotopic lumens that may be regarded as a "pupil lumen" (see Berman et. al. "Spectral Determinants of Steady-State Pupil Measurement with Full Field of View", Lighting Techniques Analysis Group, Lawrence Berkeley Laboratory, Berkeley, Calif.

Thus, when the total spectrum lamp replaces the cool white lamp, one wants only eighty five % of the vitality to produce equal illumination; by inserting a polarized diffuser with the total spectrum lamp, one wants solely forty two.5 % of the unique amount of vitality for equivalent visual efficiency.

Full spectrum lamps have been developed utilizing a mix of phosphors which produce ultraviolet in addition to seen gentle in roughly the identical proportion as present in natural daylight. Full spectrum lamps are outlined as a lamp with a Shade Rendition Index of ninety or above and a Color Temperature of 5,000 levels or above. Nonetheless, full spectrum lamps used by themselves are lacking the polarizing characteristics of natural daylight, and produce glare when utilized in lights with out polarized diffusers.

This discount in vitality use in the full spectrum polarized lighting system can solely happen when the polarized diffuser is used with the full spectrum lamp. A solid state ballast with a forty watt bipin 4 foot fluorescent lamp will devour roughly 40 watts. A stable state ballast driving two forty watt bipin 4 foot fluorescent lamps will devour approximately seventy two watts.
