Why is LED lighting important? Reduced power consumption than conventional lighting– Typical light output for a 60W light bulb is 800 lumens; equivalent light output for an LED light is around 9W, which equates to 85% savings – Impact: energy cost savings

Increased operational lifetime than conventional lighting– White LED = 100,000 hours (11 years of continuous operation/22 years of 50% operation) – Impact: reduced maintenance costs for commercial applic

ations

LED vs CFL– “Snap-on” lighting – True TRIAC dimming – Impact: better user experience

Environmentally friendly– No lead, mercury, and reduced carbon footprint – Impact: improves our environment and atmosphere6

Lighting TermsRadiant Flux (W)The measure of the total power of electromagnetic radiation.

Luminous Flux (lm)Amount of light emitted in all directions by a light source.

Luminous Intensity (cd)Amount of light emitted in a specific direction by a light source.

Illuminance (lx)The density of light on a surface.

Luminance (nit)The intensity of flux leaving a surface in a given direction.Unit

Efficacy: lumens per watt

lm (lumen) cd (candela)

Flux: the amount of light emitted in all directions by a light source

Lumen: the measure of the amount of light a light source produces

Watt: the measure of the amount of electricity consumed

lm/W or LPW or “efficacy” (lumens per watt) cd/m2 or “nit” (candela per sq. m) lux = lm/m2 fc = lm/ft2 (foot-candle)8
