Bulb brightness is measured in lumens which express the amount of light produced, while the electric power used is measured in watts.
The typical efficiency of some different types of bulb is:
Incandescent 12 lumens per watt
Halogen 17 lumens per watt
CFL (compact fluorescent) 50-60 lumens/watt
LED (light-emitting diodes) 90-100 lumens/watt.
