Tonight I worked on the “Combo” landing lights from FlyLED. The lighting arrived in a box from Australia, and it was fun to unpack and explore the parts.

The Combo lights are installed in the landing light coves on the leading edges of the wings. These are designed for tail-wheel aircraft, with a cluster of 4 lights, one of which can be angled down, wired separately, and comes with a diffuser cap, to serve as a taxi light.

The largest and heaviest part of the lights are the heat sinks, which are attached to the boards with a couple of small screws and some thermal paste.

The LEDs themselves are very small, but the lenses are larger. The lenses focus and concentrate the light into beams.

Once my bench power supply arrives, I can test these out to see how bright they are.
