T8 tells us the diameter (1-inch), but for ordinary bulbs the wattage is related
to length. For example, 12-inch are typically 8 watt, 15-inch are 14 watt,
18-inch are 15 watt, 24-inch are 20 watt, 36-inch are 30 watt, and 48-inch are
40 watt.
There are high output (HO) and very high output (VHO) bulbs, but they have
different end pins and are very unlikely in a Bird.
I would try Dupree Products for the ballast/inverter; I don't think they are
listed on the dupreeproducts.com website, but he probably has them.

Thank you. At 48" must be a 40 watt. Am thinking the best thing to do is
change out the fixture.

Can't argue with that. I made a video last year when I was doing mine - this
shows replacing 2 18-inch bulbs with about $8 worth of LED strip:
