Work in lumens, not watts
Watts tell you what a lamp costs to run. Lumens tell you how much light you get. The two stopped tracking each other the moment LED replaced filament, and buying a 50 W LED because the old halogen was 50 W is how a yard ends up half lit.
Every row in these tables prints its wattage, and the description prints the lumen output where the manufacturer states it. Match the lumens to the fitting you are replacing and let the wattage fall where it falls - that is where the saving is.
A rough conversion, for replacing what is already there
An old 100 W incandescent is about 1,500 lumens. A 60 W is about 800. A 500 W halogen floodlight is about 8,000 to 10,000. Use it to get in range, then read the lumen figure on the row.
