Lighting, light sources, economics and safety

摘要

Safety and economics in lighting designs are growing concern in both new and existing facilities. The question is what light source gives you the quality of light required for safe operation and reliability in today's facilities with a balance of the ever growing concerns today's ever growing economic crunch (total cost of ownership). This paper will compare new and traditional lighting sources and designs used today in hazardous locations, exploring limitations due to factors such ambient temperatures, physical size of lamps and fixtures, lamp efficiency, lumen depreciation, availability of different types of optics for hazardous locations, cost of fixture's, maintenance, safety of design, but not limited to just these.
