A cfl uses less power for the same light by a factor of 3 4.
Now led and cfl bulbs can create the same amount of brightness with a fraction of the energy so their wattage rating will be much lower usually between 5 and 25 watts.
So a 60 watt bulb emits 54 watts of heat and 6 watts of light.
The equivalent of a 13 watt compact fluorescent cfl light bulb is between 40 and 60 watts of power from an incandescent light bulb which corresponds to between 450 and 800 lumens.
Now you can buy a 4 pack for about 6.

Now they re becoming difficult to find.
The wattage rating is for fire safety you could use a 60w cfl in the socket if you could find one of appropriate size.
Meaning a 13 watt cfl will emit the same 6 watts of light giving off 7 watts of heat.
