How long do led light bulbs last?

LED bulbs do get hot but the heat is dissipated by metal heat sinks that wick away the heat from the light source itself. Keeping them cool with heat sinks or even liquid cooling, as Switch Lighting is doing, is important to ensuring they last as long as advertised. read more

This particular 10-year claim means that the bulb can last for nearly 11,000 hours. So if we were to have the bulb on for eight hours every day (two hours in the morning and six hours in the evening, for instance—possibly longer on the weekends), this means that it would only last shy of three and a half years. read more

While it can vary slightly depending on the bulb, on average LED light bulbs last over 50,000 hours. That would be almost six years if left on twenty-four hours, seven days a week. In terms of usage, if you leave your light on all day (16 hours), an LED replacement bulb would last 3,125 days or approximately 8.5 years. read more
