Select this lamp by matching the GE lamp number, order code, voltage, wattage, base style, and beam pattern to the installed fixture. Confirm compatibility before ordering.

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. Q4681) in its catalog under “Aircraft Landing”. Catalog beam spread is given to 10% of maximum beam candlepower (MBCP).
