LED TM-30

​Disclaimer
​
Not intended for medical advice, consult your doctor.

LED TM-30 - Learning Objectives

  1. What is TM-30?
  2. Why do we need TM-30?
  3. LED questions that can be answered by TM-30?
  4. Who can read TM-30 data?

Why use TM-30?

Since LED light sources do not mimic daylight, there is a need to have some metrics for comparison to familiar light sources of sunlight, incandescent and halogen. Lighting Facts is a good start; however, to consider more details than  Kelvin & CRI, use TM-30 metrics.
The 99 colors used for testing includes printed materials, skin tones, natural objects, paints and textiles.

TM-30 Tests for 99 Colors

TM-30 Color Type Key:  
​A-Nature  B-Skin  C-Textiles  D-Paints  E-Plastics  F-Printed Materials  G-Color Systems
TM-30 Test Colors

TM-30 Color Rendering Test Colors

  • TM-30 data is provided by individual manufacturers upon request.
  • TM-30 uses state-of-the art scientific advances in color science. As a result, it is more accurate than the CRI, especially for narrow-band spectra where the CRI can fail.
  • TM-30 provides more accurate information such as a fidelity index Rf which replaces the CRI index and indicates whether colors look natural.
  • TM-30 also provides more insight into the gamut index Rg which indicates a color's saturation and an accuracy graphic which gives advanced information about the rendering of specific colors.
