Twinstar 600e how bright?

Hi everyone, long time no see. I'm setting up my ADA 60f again for my dwarf puffers, this time it will be a blackwater with some easy plants and no CO2. I was wondering how dim I should have my Twinstar 600e, I'm looking to grow Vallisneria nana, Cryptocoryne wendtii and Helanthium tenellum. Obviously it's a fairly powerful light and the tank is only 18cm deep, so I'd imagine pretty dim but not sure how much exactly.

Cheers

Considering it's a black water setup, light won't reach plants that well to begin with, and since the Twinstar E series is not that powerful, I would set it to 40-50% and see how it goes.
