Product Questions

What is an LED?

LED stands for “Light Emitting Diode”. It is a solid-state semiconductor device that allows electric current to pass through it to produce light.


What are the benefits of upgrading to LEDs?

PWI LEDs offer a variety of benefits and reasons to upgrade your current aircraft lighting system. Our LED lights offer over 100k hour lifespans, various color temperature options, higher lumen output, operate at cooler temperatures, feature reduced weight, and are more energy efficient than incandescent lights. In conclusion, PWI LEDs reduce the amount of aircraft downtime for maintenance and installation because our products are built to last.


What are Lumens?

Lumen is used to measure the level of brightness of a light. The higher the lumens produced by a lamp, the brighter the light will be. Depending on the desired lighting situation, it may require a higher lumen output to create the desired lighting effect.

What is color temperature?

Color temperature is the color of light produced. White light is measured in Kelvin (K) and falls in a range between 1800K and 7000K. Depending on where the light falls in the spectrum will determine if the white light produced is more of a “warm white” or “cool white”. White light around 3000K produces a warmer tone, while white light around 6500K produces a cooler blue-ish tint. Various color temperatures may be used to create mood lighting or to enhance specific features.
