As the title says, do LEDs age and lose intensity over time? If so, at what point should they be replaced?
The simple answer ..yesAs the title says, do LEDs age and lose intensity over time? If so, at what point should they be replaced?
There is more likely other parts that will fail long before the LEDs are useless.The L80/B10 specification with 60,000 hours means the luminous flux of no more than 10% of all LEDs reduces to less than 80% of the initial lumens within these 60,000 hours. L70/B50 90,000 hours means 50% of the LEDs have at least 70% lumen maintenance for the projected 90,000 operating hours.
