Marketing Claim Verified by UL Solutions
LED Chip Color Rendition Rating DIAMOND based on IES TM-30-20 Fidelity Intent
Verification Method
The product is measured according to ANSI/IES LM-85, Approved Method: Optical and Electrical Measurements of LED Packages and Arrays, and IEC 62471:2006 Ed. 1.0, Photobiological Safety of Lamps and Lamp Systems. The color rendition calculation is based on ANSI/IES TM-30-20, IES Method For Evaluating Light Source Color Rendition. The fidelity design intent of TM-30-20 is graded as follows: Diamond: Rf ≥ 95 Platinum: Rf ≥ 90, Rf,h1 ≥ 90 Gold: Rf ≥ 85, Rf,h1 ≥ 85 The radiance ratio of light in the range 415 nm-455 nm versus a total range of 400 nm-500 nm is graded as follows: Diamond: ≤ 48% Platinum: ≤ 50% Gold: ≤ 52% The spectral difference refers to the difference in radiometric power between the artificial light source and its reference for visual light from 400 nm to 699 nm. Performance is graded as follows: Diamond: 425~474 nm: ≤ 25%, 630~699 nm: ≤ 35% Platinum: 425~474 nm: ≤ 40%, 630~699 nm: ≤ 50% Gold: Not required
What is UL Verification?
UL Verification is an objective, science-based assessment that confirms the accuracy of marketing claims. Our independent assessment process scrutinizes the validity of specific advertising or promotional statements, giving you a way to separate verified fact from fiction.
