LED panels are rated not only by hours of use but also lumen output over time. In general, lower usage areas that see light for just a few hours daily can expect 30,000-50,000 hours of operation from LED panels, equating to 10-15 years. Medium use spaces lighting 4-8 hours per day will get 25,000-40,000 hours or 10-12 years. Higher usage retail or warehouse ceilings operating lights 8+ hours continuously can last 20,000-30,000 hours for 8-10 years. Additionally, quality construction and cooling helps top-rated LED panels possibly reach the higher end of these lifespan estimates.
