Here’s a link to a supply house, just to give you an idea of how versatile T5 bulbs have become. They have LED tubes that work in that fixture, UV, veg, super veg, finishing spectrum, all in T5 type bulbs.
Make sure to get the newer High Output “HO” bulbs. They’re 54w per tube.
Anyway, the link is to just show the newer technologies. You can beat those prices usually. T5 HO grow bulbs.
I’ve never shopped these guys, I was just using their site to show the technology. Peace
