A photon 48 is a perfect fit

I took this pic just now to show the fixture appearance on factory mounting legs over the same size tank as yours. My tank thread is filled with pics showing coral detail and colors and growth progress
Other lights are cheaper. Others are more expensive. This is a top of the line light, at a middle of the line price. What appeals to me over others is the leds have a matrix layout vs puck, meaning they are evenly spaced completely left to right and front to back, so you don’t get hot spots or shadow spots, and one fixture can light the whole tank instead of needing to have multiple fixtures and cords and having to deal with syncing them. I also like they made the whole unit an inch thick. It’s sleek and modern and doesnt look like a bunch of hanging shoeboxes over your tank. The entire casing is aluminum heat sync, there are fans but they only come on in emergency. Mine never had to come on. The light is silent. I never have to run this over 45% and it will last many many years being underdriven
