Classroom Lighting

The amount of light needed to produce the most efficient work is still subject to controversy. An adequate amount is recommended by everyone, but the definition of adequate varies as is evidenced in the amount of foot-candles suggested. But the emphasis now has shifted from how much light should we have to how well can we see. Quantity and quality may now be regarded as the twin requirements for good lighting. This new look in school lighting can be summarized in two words--brightness control. It involves the control of brightnesses of everything in the visual field. This new emphasis not only betters visibility, but it improves the whole visual environment which results in greater comfort, increased efficiency and improved morale
