Also have a look at ultimate reef forum. There are usually 2nd hand lights for sale, although with the lockdown not at the moment.
Given the size you probably need 3 hydras or radions. Or have a look at orphek bars? Alternatively you can go for T5 bars, but LEDs will produce less heats and take less energy. Kind of lights will depend on what corals you want in the end. Significant expense, but a very important one!
