BetaLED® Essentia Lumen Maintenance Factors (TD-14)


BetaLED® Essentia Lumen Maintenance Factors (LMF) are calculations derived from our LED chip manufacturer’s lumen maintenance data and long-term lumen maintenance projections. Refer to the LMF charts to select the appropriate Lumen Maintenance Factor based on your specific light engine configuration (i.e. number of LEDs), product type (Downlight, Adjustable
or Wallwash), anticipated application life, average luminaire ambient operating temperature condition and drive current.
