Lux and CP are both light intensity at a specific distance (throw). Lumens is overall light output. Foot-Candles & Lux Lighting Terminology"> one foot-candle is approximately equal to 10.764 lux. Last, but not least, are the foot-candle and lux. Both units measure the same thing – the amount of visible light that falls on a surface. What is Candlepower? Now an obsolete term, “candlepower” originally referred to a candle’s luminous intensity in a particular direction; in short, it measured the light’s concentration. Today, we use “candela” to refer to that measurement. Spotlights are commonly measured by candlepower; for instance, a light with a candlepower of 10,000,000 means it emits the equivalent of 10 million candles. What are Lumens? Lumens is the modern measurement of a light source’s brightness, or how much of its energy is converted into light. It is also used to determine a light source’s efficiency. Flashlights, for example, are usually measured in lumens. Lumens vs. Candlepower Candlepower and lumens measure different light qualities, and 1 candlepower equals 12.57 lumens. When measuring lumens, you can also think of it as the light illuminated in a 1-square-foot area one foot away from a single candle.
