The test results (luminous distribution and flux) were obtained by using a Lighting Sciences series
6000 Type C Moving Mirror Goniophotometer

The photometric reference standard used is a set of three incandescent luminous intensity
standard lamps calibrated and traceable to the U.S. National Institute of Standards and
Technology.
The test results (colorimetric and luminous flux) were obtained by using a Labsphere Model LMS-760
Integrating Sphere. 4 geometry was used. Correction factors were applied for self-absorption.
