We’ve compiled some questions and their answers to hopefully solve any questions you might have.

Why should I upgrade to LEDs?


PWI’s LEDs can last over 100,000 hours – a significant improvement over incandescent and both hot and cold fluorescent bulbs. PWI’s LEDs are also unique in that they have a groundbreaking heat-eliminating technology that greatly reduces their operating temperature. They are also much more energy efficient, have little to no EMI, and have a lower current draw.

KAR stands for King Air Retrofit. KAR Kits are PWI’s LED lighting upgrade systems that are specifically designed to replace the old flourescent lights in the King Air lines of aircraft. Learn more about which series can be upgraded here.
