Not all aspects of a luminous inten

Not all aspects of a luminous intensity distribution can be captured numerically using readily available metrics. In some applications, the smoothness of the beam pattern from the center to the edge can be very important. This characteristic lacks a metric, but adjectives such as “smooth,” “spotty,” or “uneven” are sometimes used. This attribute was not analyzed as part of this series of CALiPER testing, although it is intended to be an important aspect of the continued evaluation of the Series 20 LED PAR38 lamps.
