Unlike conventional light sources LEDs are not subject to sudden failure or burnout but rather they gradually degrade in performance over their lifetime.
LED chips can last up to an outstanding 50,000 hours!
This is equivalent to 5 years of uninterrupted operation, 10 years of 50% uninterrupted operation.
Around 15 years if you leave on the light for 8 hours each day.
As LED fittings last at least 10 times as long as conventional light sources, there is no need to replace them as often.
This drastically reduces, time, effort , man power and in some cases even the cost associated with changing out lighting fixtures at regular intervals
