So I had this old T-5 4 bulb fixture with a burned out ballast, sooooo I ripped everything out. Then I turned it over and screwed in the cable hangers. Then I taped on 12 each 2 foot 3000K EB strips. And I powered it with a 320 watt 1050ma Meanwell driver. Total dissipation watts about 285. And the fixture is remarkably cool. About 99F on the back of the fixture with full power. Voltage droop is about 1.5%, so the strips are staying cool.
Note: wiring is not "pretty"...this is only a test, but if you have any old similar fixtures, they make a great heat sink for the EBs running at 45 watts! And the fixture could easily handle 2 more strips at 45 watts each. And 2 of these fixtures as is could cover a 4x4 pretty well...just saying.
