The power rating is printed on the lamp holder, expressed in watts. As power describes the rate of energy consumption, you need to convert the number of watts into kilowatts (divide by 1000) and multiply this figure by the time for which the lamp is in use (expressed in hours) -this will tell you the number of kilowatt hours of energy used.
