  • What's CRI, IES TM-30, TLCI & CQS and Why is It Important?
    May 22, 2024

    What's CRI, IES TM-30, TLCI & CQS and Why is It Important? Part.1

    CRI is limited in its evaluation because it only considers the reproducibility of the light source for a small number of specific colours, while ignoring other important factors. The advent of TM30、CQS and TLCI compensates for some of the shortcomings of CRI and provides a wider range of indicators for evaluating the colour rendering ability of light sources.
    More colour indicators are needed to provide data support for users in various industries to make informed choices.

  • TM-30 Tested LED
    November 24, 2023

    TM-30 Tested LED

    TM-30 offers comprehensive evaluation on color quality of new light sources,providing quantified measurements on overall average properties and describing a method for evaluating light source color rendition.
    The fidelity index Rf has been introduced to the Technical Report CIE 015:2018 and it is aiming to be a new standard for color evaluation. Comparing to Ri of Color Rendering Index, the Rf, CESi of TM-30-18 is more comprehensive to evaluate much more colors.

    5 Kinds of Monochromatic Light that Affect Plant Growth

    Light is one of the most essential environmental factors for plant growth. It is not only the basic energy source for photosynthesis but also an important regulator of plant growth and development. Plant growth and development are affected not only by the light intensity (photon flux density, PFD), but also by the quality of light which means different wavelengths and radiation, and their different composition ratios.
