I replaced most of my shop lights with LED. I did see when shopping that there are some discrepancies or differences in watts used varying from one manufacturer to the next. In most cases I saw about a 50% energy savings with LED.
Couple pictures from some websites talking about energy differences.
The tubes may be 20 watts or so but then you have the ballast power to consider as well
