Fluorescent lamps are the most commonly used light source in public facilities.
T8 lamps are available in a variety of lengths from 2 to 8 feet and in several U-shaped versions. The improved triphosphors that are standard in the T8 lamp have improved the color rendering of fluorescent light. The use of triphosphor coatings not only improves color rendering and boosts efficacy, but also reduces lumen depreciation over the lamp s life, resulting in an increase in overall system performance. Light quality is important for energy efficiency because areas with higher quality lighting need less illumination. High color rendering increases the perceived light level and reduces the need for additional task lighting.
