I just took a number samples of some of various size LED floods, they are rated from 60 to 70 lumens per volt-amp.
My brand new LED replacements are rated for only 75 lumens per volt-amp.
My regular T5 tube do about 107 lumens per volt-amp
My inefficient T5 high output tubes do 92 lumens per volt-amp, but these are supe bright and start at 0°F, since my T5 HO lights are out side or in building's that are unheated this is kind of important.
Either way, a lot more efficient than LED.
Why does everyone green wash all the LED tech and slam florescent?
Yeah old 1960s tech like T12 florescent suck.

Unlike LED you can actually get high quality T5 parts.
German made T5 tubes are the best by far but they are expensive, around $20 per 4 foot tube. Roughly double the price of Chinese tubes.
Most but not all ballasts are made in china, I have seen a few made in Mexico.
