What is National Institute of Standards and Technology (NIST)
NIST, which stands for the National Institute of Standards and Technology, is an organization in the lighting industry. They conduct research, provide standards, and offer measurements for various industries, including lighting. In the given context, the term “NIST study” refers to a research study conducted by the National Institute of Standards and Technology to validate a mass/force approach in the field of lighting.

The study conducted by NIST found a strong agreement between the results obtained using the mass/force approach and those obtained using the conventional method. This suggests that the mass/force approach proposed by NIST is a valid and reliable method for measurement in the lighting industry. The study also highlighted several significant advantages of the NIST proposal, including the use of a portable primary standard in the form of a reference mass and the potential for improved precision.
Furthermore, NIST’s involvement in the lighting industry extends beyond this study. They collaborate with other standardizing bodies and related groups to develop standards for solid-state lighting (SSL) products. This includes aspects such as color specifications of LED lamps and fixtures, test methods for measuring total light output, energy efficiency, and color quality, as well as nomenclature for LED components and products.
