Calculating Light Loss Factors - Energy

LED Sources L. p = time in hours to which the lumen output has degraded to a percent “p” of initial lumens L. 70. commonly used Use LM-80 report to help determine L. p. Note: LED lamps do not typically catastrophically fail. There lumen output degrades over time. This can be maintained through drive current control. 7

Energy Efficiency of LEDs

Figure 3 shows efficacy versus lumen output for more than 7,000 LED lamps and luminaires listed by LED Lighting Facts as of February 2013. For both integrated LED lamps and LED luminaires, the listed efficacy ranged from less than 10 lm/W to approximately 120 lm/W. A majority of products were between
