The advantages of durable luminaires
A comparison of investment costs
Decisive for the standard-compliant operation of lighting systems are lumen maintenance and the LED failure rate. Comparing an ERCO high-performance LED (L90/B10) with a standard LED (L70/B50) demonstrates the positive effect of high-performance LEDs on investment costs. An office with a uniform matrix of luminaires consisting of 50 downlights serves as a reference. Light distribution is identical in both offices. The LEDs however differ with regard to lumen maintenance and failure rate. The analysis shows that reinvestments are inevitable in the long run with lower LED quality.
