All photometric and electrical data for SIRS-E® and our ODM LED Tape are measured in compliance with IES LM–79–24 and ANSI C82.77:2002. Our colorimetric data follow IES TM–30–24, CIE 013.3–1995, CIE 15:2018, and the chromaticity specifications of ANSI C78.377–2024. Lifetime and lumen maintenance data are tested in accordance with ANSI/IES LM–80–21. Where applicable, SDCM (Small Deviation of Color Matching), also referred to as the MacAdam ellipse, is used to define color consistency, referencing Specification of Small Chromaticity Differences by David L. MacAdam.
