Lighting Efficiency


Common characteristisc used to evaluate lamp quality include efifciency measured in lumens per watt, typical lamp life measured in hours, and Color Rendering Index on a scale fo 0 to 100. Cost of replacement lamps is also an important factor in any design. Some buildings, like warehouses and office buildings, are primariyl concerned with asving money through the energy efficiency of the lgihting sytsem. In addition, glare or excess light can decrease worker efficiency (DiLouie, 2006).
