6. Will I get enough light with LEDs? For how long?

LED fixture manufacturers should be able to demonstrate the real life performance of any given product through extended whole fixture testing. WAC Lighting's LEDme™ fixtures have published photometric data available on  WAC Lighting web site with downloadable specification sheets that provide actual photometric data covering efficiency, light output and distribution, quality of light, and life of the light source.

Photometrics example

A-Aiming angle, D-Distance from fixture to Floor*, FC-Initial foot candle level at the center of the beam, L-Listing at the point that the candle power drops off to 50% of maximum*, W-Listing at the point that the candle power drops off to 50% of maximum*
*Measurements in feet
