Ah, yes, but those $20 pre-assembled LED fixtures (I have and use many) can’t compete output-wise with a pair of 40 watt (actual) LED tubes.

The LED tubes I just looked up are 14 to 28 watts actual.

Many of the "T8 LED Bulbs 4 Foot" are rated at 40 Watt equivalent.

During my quick search I did not find 40 watt actual LED tubes. Not saying they don't exist. OK, just now I found a 36w (actual) by ShopLED, equivalent to 72 watt fluorescent.
