If we use the light bulb 6 hours a day, 30 days a month, that's 180 hours a month. Multiply that by the savings rate, and you get an energy saving of 10.8 kWh per month. At the costs of the light bulbs we use, and of electricity, we recover the cost of the light bulb in 1-2 months - and the light bulb typically lasts much longer than that. However, you should look how much YOU pay for electricity - just look at the bill from your power company.
