Lights for Indoor (bathroom) Orchid Wall (and other advice?)

[MesozoicMiss]

Hey all!

Here's the plan! I have a pretty large blank space on my wall (3' x 4') in my bathroom and I would like to do an orchid wall there!

There is no light for plants in the room. The only light is an overhead light and a bathroom mirror vanity light. The bathroom does end up staying pretty warm and fairly humid. There is a towel rack that I could clamp some upwards facing lights onto.

I think I've determined the easiest way to do this living wall is a frame (I'd laser cut a screen, cause I'm extra like that) and then hang mounted orchids from hooks on the screen so I could take them down to water them effectively. But I am open to other suggestions

I've thought of getting more extra and putting hygrolon in a frame and layering the laser screen over, making the orchids detachable from the frame and growing moss on the hygrolon spaces in the screen pattern. See? I told you, extra.

I'm looking for affordable lighting advice! Since I'm only operating in hypotheticals I was guessing that I could light from the bottom or the top and have orchids with high light demands closer to the lights and then decreasing light requirements further from the lights.

Other important considerations. I'm a total newb at orchids, but I am excellent at following instruction, advice, and care sheets. I do like big projects, and am not overwhelmed but I do need to stay affordable. So please hit me with whatever advice you have*
