After some trial and error, and disassembly, I was able to determine the power requirements for this light. I swapped out the lamps to 120V PAR56 and purchased a transformer to run the 24VAC rotation motor. I might explore LEDs in the future, but the retrofits are extremely cost prohibitive. I’m also considering painting this unit red or orange to match beacons at US civilian airports and helipads.
The unit is not very loud but it seems rather noisy in the video.
