Test Procedures and conditions: Goniometry: Electrical conditions and physical orientation were set as required by the lamp manufacturer or the customer Ambient temperature was controlled at 25+/-1 degree Celsius and measured at the approximate height of the sample mounted on the Goniometer equipment Calibration was based on National Institute of Standards and Technology certified total luminous flux standard and maintained by a set of incandescent reflector working standard laps Lamps were stabilized per LM-79 requirements LSI type C High Speed Mirror Goniometer was used to measure intensity (candela) at each angle of distribution Burn time during testing for each lamp: 1.25 Hours Stabilization time during testing for each lamp: 1.25 Hours Sphere Spectroradiometry: Electrical conditions and physical orientation were set as required by the lamp manufacturer or the customer Ambient temperature was controlled at 25+/-1 degree Celsius and measured inside of the sphere, shielded from direct radiation of the lamp Calibration was based on National Institute of Standards and Technology certified total spectral flux standard and maintained by a set of incandescent working standard lamps. Lamps were stabilized per LM-79 requirements Optronic 770 Spectroradiometer attached to a 1.5 or 2 meter sphere painted with high reflectance paint was used to measure correlated color temperature, chromaticity coordinated, color rendering index, total luminous flux, and spectral power distribution. Sphere measurement was set up in 4π geometry and used continuous self-absorption correction. Burn time during testing for each lamp: 1.25 Hours Stabilization time during testing for each lamp: 1.25 Hours Spatial correction factor applied to lamp measurement: 1
