Will LED lights save more money than just turning lights on and off when needed?

LED bulbs are 75 – 80% more efficient than incandescent bulbs, which means in order to save the same amount of money by turning off incandescent bulbs, you would need to have your lights off 75 – 80% longer than you would if you had LEDs. For example, having an LED light bulb on for 4 hours uses the same amount of energy as a traditional incandescent bulb does in just 1 hour.
