TM-30-15

Lumino is the first company in the UK to test its products according to TM-30-15.

This report details the findings of tests conducted on Lumino’s ColorCORE® linear products by LUX-TSI according to colour rendering method TM-30-15.

Technical Memorandum TM-30-15 is a new method of evaluating light source colour rendition published by the Illuminating Engineering Society of North America (IES)in 2015. The CIE 1995 method for measuring CRI Ra relies on just 8 colour samples contributing to the Ra value. TM-30-15 uses 99 new colour evaluation samples (CES) to measure colour fidelity Rf with an additional measure Rg for gamut area.

TM-30-15 describes a method for evaluating light source colour rendition, quantifying the fidelity (closeness to a reference) through a Fidelity Index (Rf) and gamut (increase or decrease in chroma) through a Gamut Index (Rg) of a light source. The method also generates a color vector graphic that indicates average hue and chroma shifts, which helps with interpreting the values of Rf and Rg.
