What is the Most Effective Way to Manage Commercial Lighting?
Only apply as much light as minimally needed using fully shielded fixtures that prevent glare and excessive upward light spill to assure safe and secure conditions on your property. Install an astronomical time clock to assure needless energy is not wasted after business hours. An astronomical time clock uses a photosensor that automatically synchronizes switch settings with varying daylight that changes during the seasons and does not require resetting each time there is a power failure.

A physical phenomenon whereby an atom of a material absorbs a photon of light and immediately emits a photon of longer wavelength. If there is a significant delay, the phenomenon is called phosphorescence rather than fluorescence. It is interesting that "phosphors" used in lamps exhibit "fluorescence," not "phosphorescence."
The GE Edison Award is an annual competition where lighting designers submit their best projects. The entries are judged by an international panel and awards are presented at a banquet accompanying Light Fair, the North American trade show for the lighting industry.
The international unit (SI) of luminous flux (quantity of lights). For example, a dinner candle produces about 12 lumens and a standard 60-watt incandescent bulb produces 830 lumens. The higher the number is, the brighter the light is.
