How is the candlepower of a lamp calculated?

Answer:

The candlepower of a lamp is determined by multiplying the Lux reading from the light metre by the square of the distance (in meters) between the light source and the meter's probe.

To calculate the candlepower of a lamp, the light fixture is positioned back from the light metre, and the probe of the light metre is exposed to the light. By multiplying the Lux reading from the light metre by the square of the distance between the light source and the meter's probe, you can determine the candlepower value.
