All of the photometric testing (Goni-photometric or spherical) is done in complete adherence to applicable IES Photometric Guidelines and Recommended Practices.
“IES FILES” A standardized data file which expresses the light output of a luminaire as luminous intensity versus angle along with sufficient descriptive and documentary test information it is derived from the acronym for the Illuminating Engineering Society of North America (IESNA). IES files are assigned the file extension “.ies”. Used by lighting designers to model the illumination performance of a lighting scheme using commercial lighting design programs. An IES file is commonly referred to as “photometric data” for a luminaire.
Customers are issued a complete test report (in PDF format) along with the resulting IES file for use in most application and modeling programs.
Standard Tests Include:
Lamp/Luminaire efficacy (Lumens per Watt)
Color rendering index (CRI)
Correlated color temperature (CCT)
Spectral distribution measurements
Luminous intensity distributions
Reflection and transmission measurements
