In Hong Kong, I'm designing a show with light beams and i'm thinking using Robe Megapointe lights (https://www.robe.cz/megapointe/). I've been ask by the client to follow the aviation regulation. Though the aviation regulation doesn't give any figure, only subjective indications, and I have no idea if my lights are acceptable or too strong.
The website of Robe announces: 2.200.000 lx @ 5 m and 137.500 lx @ 20 m. I'm trying to find similar regulation references in other countries to make up my mind.
Any of you have seen any figures in that domain?
