Do LED light bulbs really last 10 years?
The 10-Year Lifespan Assumes a Lot About Your Usage. Even the cheapest LED light bulbs (Philips sells some for as low as $2 per bulb) claim to have a 10-year lifespan, but it’s important to know that’s actually based on some pretty modest assumptions. If you read the fine print (notice the asterisks next to the 10-year claim in the image above), a 10-year lifespan is based on only having the bulb on for three hours per day, every day.
How long will LED light bulbs realistically last?
The reality is that the lifespan of an LED light will typically fall within a range of about 4 to 6 years. For instance, an LED light could last 10 years, but it may only last for 8 if it’s frequently used outdoors in extremely hot temperatures, or it may last 12 years if the light is kept in a room-temperature location and rarely ever used.
