DENO LED Lighting

LED Spectrum & CRI Report Tool

The spectrum module digitises integrating-sphere reports and presents CRI, R9, TM-30 fidelity and gamut side by side for violet-excited full spectrum and high-CRI tape.

How the LED Spectrum & CRI Report Tool works

The spectrum module digitises integrating-sphere reports and presents CRI, R9, TM-30 fidelity and gamut side by side for violet-excited full spectrum and high-CRI tape.

Museum, retail and horticulture specifications can be checked against the reported values before a sample is ordered.

  • CRI (Ra) and the saturated red R9 value.
  • TM-30 fidelity (Rf) and gamut (Rg).
  • Values read from integrating-sphere reports.

Frequently asked questions

What is the difference between CRI and TM-30?

CRI averages a small set of test colours, while TM-30 reports fidelity (Rf) and gamut (Rg) across 99 colour samples, giving a fuller picture of colour rendering.

Why does R9 matter for LED strip?

R9 measures rendering of saturated red, which the general CRI average does not include; it matters for skin tones, food and retail displays.

Where do the spectrum values come from?

From integrating-sphere test reports for the specific product; the tool reads and compares those reported values.
