Lighting for NUVO 30 aquarium

I've been wanting to purchase the 40 Gallon Nuvo Fusion aquarium, but it's been out of stock on Marine Depot for weeks and isn't expected to be available for another 4-6 weeks.  Because of the delay, I'm now contemplating getting the 30 gallon version, which is longer than the 40 gallon.  I've been planning to put 1 AI Hydra 26 over the 40 gallon.  Would I need to lights for the 30 gallon version.  The dimensions of the 30 gallon are:  36” x 15” x 13”
