First PAR64 LED aircraft landing light is cash, energy saver

Hoffman Performance Lighting has introduced the first-ever PAR64 LED Landing Light, a drop-in replacement for existing Q4559 and Q4559X quartz halogen lamps. The ruggedized PAR64 is used on a wide range of commercial, civil, law enforcement, aero-medical, and military aircraft. With FAA approval pending, this new landing light technology meets or exceeds all FAA and MIL specifications and is fully qualified to RTCA DO160, MIL-STD-810, MIL-STD-461, and other requirements for both fixed-wing and rotor-craft applications.

But what's so cool about this LED?

Hoffman's PAR64 LED Landing Light is rated for more than 50,000 hr of operating life and maintains over 600,000 candela output over its entire service life. In comparison, the output of the incandescent bulb it replaces degrades quickly over the service life of the lamp, losing as much as 50 percent of initial output in the first 30 hr of the bulb's 100-hr rated operating life.

The innovative control electronics, ruggedized housing, and LED design of Hoffman's PAR64 solve inherent incandescent design concerns such as abbreviated service life and premature failure due to extreme temperatures, shock, vibration, and weather that can result in costly service delays. This new LED Landing Light consumes only 10 percent of the power required by current sealed-beam lamp technology. Operating at 80 percent efficiency, and losing just 20 percent of its energy as heat, the PAR64 LED design eliminates the possibility of structural damage to aircraft bodies from thermal radiation.

Power-wise, this lamp is a real energy miser. The PAR64 LED Landing Light consumes only 60 W of power, compared to the 600 W required for incandescent landing lamps. The reduced draw results in lower energy consumption and increased savings across an aircraft fleet. The LED Landing Light also provides a significantly higher color temperature light output and superior brightness, improving aircrew visual acuity and aircraft visibility.

Designed as a direct drop-in replacement to Q4559 and Q4559X lamps, the PAR64 LED Landing Light is easy to install and requires no airframe modifications or training for maintenance. The lamp assembly is ROHS, WEEE, and REACH compliant, recyclable, and free of toxic chemicals. Designed for safety, the PAR64 features three independent LED light sources to provide triple redundant reliability in the event of an LED failure. The protective lens is UV resistant, hard-coated, and shatterproof.

Hoffman Engineering has been innovative in producing direct-replacement LED bulbs where the specifications call for exacting standards. The company also offers a complete line of off-the-shelf solutions for crew station and cargo area lighting.
