LED Lighting in Family Homes: UK Durability Survey 2026
LED lighting is sold on lifespan, and lifespan is the specification most likely to mislead, because rated hours describe the diode under controlled conditions rather than the fitting, the driver or the insulated ceiling void it has to shed heat into. Our 2026 report explains that in a family home the component that fails is almost never the LED: it is the driver, and specifically its heat sensitive capacitors, which is why integrated fittings are discarded while their light source still works. We rank the real determinants of durability as heat, driver quality, switching frequency and mechanical handling, note that hallways and bathrooms punish drivers hardest because they are cycled many times a day, and separate genuine failure from the disappointments that are not failures, principally mismatched colour temperature and dimmer incompatibility....
