How much energy does a sixty watt light bulb use to yield light?

It takes 60 watt-hours. Same as lighting a 1-watt bulb for 60 hours; or 60 bulbs of 1 watt each for 1 hour. You get the idea.
Notice the units: watt-hours, not watts. Watt is a unit of power, watt-hour is a unit of energy. 1 watt-hour = 0.001 kWh (kilowatt-hour) = 3600 joules = 860 calories = 3.4 BTU.

∙ 14y ago60 watts means the same as 60 joules per second. This is the energy used; all of the energy will be given off by the light bulb (but not all of it will be radiated as visible light).

∙ 11y agoAssuming the bulb is connected to the proper voltage, all 60 watts of energy are "lost" in a light bulb, mostly converted to heat and a small amount as visible light.
If you meant how much energy is used to create a 60 watt bulb, that's completely different.

∙ 15y agoA 60 watt bulb uses 60 joules per second, or 21 kilojoules per hour.

∙ 13y agoA 60w bulb produces 60whr every hour, or 1whr per minute. So it uses 1/60 whr per second.
