Product Description

The 4591 is a quartz halogen PAR 36 sealed-beam landing lamp that delivers a focused beam for aircraft landing applications using a 28-volt, 100-watt power input and 90,000 beam candlepower.

0 1. Overview

Within its PAR 36 format, the 4591 landing lamp belongs to a quartz halogen family designed to sustain light intensity over extended service life compared with standard incandescent PAR lamps. The lamp maintains its rated beam candlepower through its operating life, avoiding the light output decline associated with filament deterioration in conventional incandescent designs. This performance characteristic supports consistent visibility for aircraft operations that rely on PAR 36 landing light assemblies requiring the 4591 designation.
