TECH BRIEFING
LED BINS

The binning of LEDs is a practice used by LED manufacturers to manage the variation of LED performance that is inherent in the mass production. LEDs of similar appearance to the human eye are put in different boxes, or bins. LEDs from the ‘best’ bins are more expensive. Additionally LED manufacturers often operate slightly different binning policies from each other.

IRC

IRC halogen lamps are sources where the central halogen burner has been coated with an infra-red coating (hence IRC). This reflects the infra-red energy back onto the tungsten burner, which means it heats up and becomes more efficient as much of the reflected heat energy is turned into visible light.

LOR

Light Output Ratio – the percentage of light emitted from the light source that makes it out of the luminaire. An LOR of 70 means 30 per cent of the light from lamp is lost inside the reflector and light fitting.
