PWI is now offering an LED cabin lighting option for Hawker 400XPs and Beechjet 400/400As under an FAA parts manufacturer approval (PMA). The company's system replaces existing fluorescent lighting with LED hardware, providing an upgraded cabin experience while reducing maintenance requirements. Four new LED cabin lighting system part numbers are included in the PMA supplement.

“Our LED cabin lighting systems enhance the flight from boarding through disembarking—the entire aircraft passenger experience,” said Robi Lorik, president and CEO of PWI. “Beechjet 400s have been a popular aircraft from their introduction, and our LED cabin light system helps extend that service.”

The LED lighting system replaces power inverters and fluorescent tubes, removing the need for high-voltage operation and reducing the potential for electrical interference. It features 4,000K neutral white light and a service life of 100,000 hours, as well as no heat generation. To ease installation, it uses the aircraft’s existing wiring and 28-volt power supply, and the LEDs are designed to match the size of the original fluorescent fixtures.

Beyond improved reliability, the LED system offers instant-on performance without the flicker, hum, or buzz commonly associated with fluorescent lighting.
