FYI, I did my lights out of 8020 as well. Mounted to the wall, and built sliding trays to move them for easier tank access. Let me know if you want to see them.A really tough part of this project was the lights. This was now around 2017ish and I knew lights were changing and I was now working for a lighting company that is now out of business. I wanted something that I could adapt if needed but also not rust away. I decided to go the 8020 option.
Here are some of the design I was looking at.
