There’s different types of LED light so the cost will vary but if you do buy LED light bulbs you need to consider far more than just the initial cost. Other factors such as the amount of electricity saved in comparison to other bulbs should come into your thinking. For example, an incandescent light bulbs should last around 1,200 hours but If you compare this to the average lifetime of an LED bulb, at 60,000 hours, you start to see the savings that can be made. You would need between 45-50 incandescent bulbs to last this long.
