WHERE HAVE ALL THE LUMENS GONE?!
  –Light output decreases at real operating temperatures (droop effect) 
–Warm White / Hi-CRI LEDsare 20-50% less efficient than the top 
performing products –Optical losses typically 10-30% in LED lens / 
diffuser elements –Electronic drivers are currently less efficient than 
for other light sources –LED drivers typ. 50% to 85% efficient –c.f. 
Halogen 95% efficient, HID/FL 80-90% efficient.
