The operational life of white LED lamps is 50,000 hours. This is 10 + years of continuous operation, or 20 years of 50% operation. The long operational life of an LED lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. The long life span of the LED has naturally a direct impact on maintenance requirement.
With incandescent bulbs, the true cost of the bulb is in the cost of replacement, the labor expense and time needed to replace them. These are important factors when considering an average office, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED lighting option.
