Product Overview
A PAR46 sealed beam lamp has its filament, reflector, and lens factory-sealed as one unit, so the beam pattern is fixed by the lamp. Beam spread, intensity, voltage, and base style therefore determine which lamp number is correct for a given fixture, and like-for-like replacement is the safest approach.
GE lists this lamp (no. 4553) in its catalog under “Aircraft Landing”. Catalog beam spread is given to 10% of maximum beam candlepower (MBCP).
