LEDs are around 10x more efficient than incandescent bulbs. A 100W incandescent equivalent LED bulb typically consumes 10-12W. A 70W LED would put out as much light as 700W of incandescent.
The designed lighting for a room in my house is 2 x 60-watt incandescent bulbs.
The equivalent wattage in 3 x 40-watt led bulbs is equal to 2 or 3 fluorescent light fixtures in an office building.
