Lamp Life

Lamp life rating is the point in time when 50% of the tested samples have burned out and 50% still shine.

Lumens, Candlepower, Footcandles

In lighting, the basic unit for the amount of light produced by a light source is called a lumen. As with any unit of measure, the lumen must be related to some physical standard. A candle of specific composition and size serves this purpose and is said to emit one candlepower. If this candle were placed at the center of a sphere having a radius of one foot, one lumen, by definition, would fall on each square foot of the sphere’s surface. Since, from geometry, the total surface area of a one-foot radius sphere is 12.57 square feet, there are 12.57 lumens given off by the standard candle. One lumen falling on 1 square foot of a surface produces illumination of one footcandle.
