A lux reading in the brightest portion of the beam is taken at some distance (2m, 10m, or 30m) with the light on its brightest mode and tightest focus at some time between 30 and 120 seconds of turning the light on. The lux reading is multiplied by the square of the distance in meters to get candela. Regardless of the distance at which the reading is taken, you should end up with the same value in candela, therefore the measurement is independent of distance. A lux reading taken at 1 meter distance is the same as candela (since 1 squared is 1). | ||
