LF- equipment for school tank

[Sixpack]

I'm helping a local high school start up a saltwater system and would appreciate any lighting that you may have that would like to sell cheap as the budget is coming out of the teachers pockets and not the schools budget. The goal is to teach marine sustainability via coral culturing and rearing of Bangaii cardinals.
The tanks that is being used is 48x24x16
We just need some dry rock and lighting. The rest is set up already.
Tks pls pm me if you have something that will help.
