How long do LED lights last? is one of the most commonly asked questions when consumers are looking at them for the first time. Actually, the answer is dependent on the type of the LED light that is being used. Some LED lights are rated as having a life span of 100,000 hours while others are rated at 50,000 hours. It depends largely on the product and manufacturer. With this said, LED lights in general, last a lot longer than any of the other lighting sources that are available on the market today. There are literally hundreds of different uses for LED light technology, but as an example, here are a couple of uses that should give a clearer picture.
How Long Do LED Lights Last in Flashlights?
There are a wide variety of flashlights being sold today that come in a variation of sizes and shapes, with variable levels of brightness. LED technology differs with each company and manufacturer so it is hard to say which will last the longest, or be the most effective. With that in mind, it is important for consumers to pay special attention to the specifications listed on whatever product they are considering.
In general, an LED flashlight will last many times longer than a flashlight that is lit with incandescent bulbs. The life expectancy of the bulb in an LED flashlight ranges from 50,000 to 100,000 hours. Also, because LED lights are energy efficient, consumers will find that each fully charged set of batteries will last more than twice as long as when powering flashlights with incandescent bulbs.
How Long Do LED Lights Last in Traffic Lights?
Not only do LEDs, when used for traffic lights, provide a much brighter colored light, but they also save the city a lot of money in regard to regular maintenance on the lights. Standard incandescent bulbs in traffic lights can blow as often as five times per year. When a person considers the money a city will have to pay in extra labor to have these repairs done, along with the cost of the replacement bulb, it can be quite a significant amount when multiplied by the approximate all the traffic lights in the US! LED lights will last for approximately a decade, and during that time will only need to have the outer lenses cleaned every so often.
These are just two of the common uses for LED lights. Because there are so many other types of LED lighting, it is difficult to state definitively how long they will last as a general statement. However, a good rule of thumb is that most LED lights have a lifespan of 50,000 to 100,000 hours of usage. In comparison to incandescent bulbs that have a life expectancy of 2,000 hours, that is quite a difference. Not only do LED lights last longer, they are also significantly more energy efficient and much safer for the environment.
