Lighting suggestions for a 50g hex?

[ange]

I'm trying to figure what would be best for this tank as it's very tall but doesn't have a large footprint. Another possible challenge is that the lid is textured and diffuses light differently. I'm planning to use an inert sand substrate, root tabs, liquid ferts, and no CO2. I attached some photos to give an idea of size/hardscape as well as the lid. The light above the tank in the photo is just the flashlight from my phone.

Plants that are going in (either from a tub outside or another tank):
Amazon frogbit
Amazon sword
Azolla
Java fern
Java moss
Jungle val
Leopard val

My main concern is the val since I'm not very experienced with its needs. I got my plants in a trade from a local hobbyist but have zero experience with it personally beyond keeping it in an outdoor tub with my ferns after the trade.

In hindsight, this should have been posted in the plants section. Oops

I would look into a spotlight kinda like this one I have never tried this one but other full spectrum white lights like this do work for the easier plants. But you should look into spotlights more
