GE 4552 PAR64 Aircraft Landing Light – 28V 250W Sealed Beam, Screw Terminal (GE 40576)

The GE 4552 is a sealed beam aircraft landing light designed to provide high-intensity illumination during takeoff, landing, and taxi operations. Its narrow beam pattern helps pilots clearly identify runway markings and obstacles ahead. Because landing lights must operate reliably in demanding conditions, this lamp is built specifically for aviation environments. It is commonly installed in aircraft landing or taxi light assemblies.

The GE 4552 produces a very narrow spot beam, which concentrates light into a focused pattern rather than spreading it widely. This design helps maximize forward visibility by directing light farther down the runway. According to the manufacturer’s photometric data, the beam spread ranges from approximately 7 to 10 degrees horizontally and 8 to 10 degrees vertically.

The GE 4552 landing light produces extremely high intensity for aviation visibility. The lamp delivers a maximum beam candlepower of approximately 500,000 MBCP, providing strong forward illumination during night operations or low-visibility conditions. This high output helps pilots see runway surfaces, obstacles, and approach lighting systems more clearly.

The GE 4552 aircraft lamp operates at 28 volts and 250 watts, a common electrical specification for many aircraft lighting systems. This configuration allows the lamp to produce strong illumination while remaining compatible with typical aircraft electrical systems. Using the correct voltage is important to ensure proper brightness and lamp life.

A sealed beam lamp integrates the reflector, filament, and lens into a single sealed unit. This design protects the internal components from vibration, moisture, and contaminants commonly encountered during flight. Because the components are sealed together, the entire lamp is replaced when it reaches the end of its service life. This construction improves durability and consistent beam alignment.

The GE 4552 uses screw terminal electrical connections, which are common for sealed beam aircraft landing lights. These terminals allow technicians to securely attach aircraft wiring to the lamp during installation. Proper tightening of the terminals ensures reliable electrical contact and consistent lamp performance. Screw terminals also make replacement straightforward during routine maintenance.

The GE 4552 has a nominal rated life of approximately 25 operating hours, which is typical for high-output aircraft landing lights. Because these lamps operate at high brightness levels, they prioritize illumination performance over extended lifespan. Operators typically replace landing lights periodically during scheduled maintenance. Proper installation and voltage regulation can help maximize lamp life.

The GE 4552 features a PAR64 bulb design with an approximate diameter of 8” and a maximum overall length of 3.75”. These dimensions allow the lamp to fit standard PAR64 aircraft lighting fixtures. The compact, sealed-beam design also helps maintain proper beam alignment within the aircraft lighting assembly.

Very narrow spot beams allow landing lights to project light farther ahead rather than spreading it across a wide area. This helps pilots see runway conditions earlier during approach and landing. Concentrated beams are especially valuable during nighttime operations or low-visibility conditions. They provide better long-distance illumination than wide flood beams.

Before installing a replacement aircraft landing light, operators should verify the lamp’s ANSI code, voltage, wattage, base type, and bulb size. The GE 4552 is identified by ANSI code 4552 and product code 40576, which helps ensure the correct replacement is selected. Matching these specifications ensures the lamp will fit the aircraft lighting assembly and operate correctly. Consulting aircraft maintenance documentation or an aviation parts specialist can also help confirm compatibility.
