The wattage on a bulb measures how much electricity it uses, not its output. What you need for output is lumens. How that is related to wattage depends on what sort of bulb it is. An old fashioned incandescent tungsten bulb converts only about five percent of the energy to light, so a 40 watt bulb gives 400 lumens whereas 'energy saving' cfl ones are much more efficient so you only need 9 watts for the same brightness. Led's and halogen bulbs are different again. All types of fitting come in a range of brightnesses. It also depends on what you consider 'dim'. I'd find an incandescent 60 watt bulb in my living room far too dim, and a 40 watt one useless. Other people are happy with 60 watts.
