CRI,UGR and CCT requirements for commercial lighting of circular round pendant light Commercial lighting is a professional lighting for office and other commercial applicatons. It has strict requirements, including CRI (Color Rendering Index), UGR( Uniform Glare Rating) and CCT (Correlated Color Temperature).

Firstly, Color Rendering Index is a parameter that measures the color restoration ability of a light source, with higher values indicating strong color restoration ability. European contries generally require a CRI of over 80 for commercial lighting.

Secondly, Uniform Glare Rating is a psychological parameter used to measure the subjective of light emitted by lighting devices in the visual environment to discomfort in the human eyes. The Uniform Glare Rating requirements for commerical lighting are generally below 19 to avoid glare causing eye injury or discomfort.

Finally, Correlated Color Temperature refers to the color temperature of the light source. Most of customers require a Correlated Color Temperature of 3000 Kelvin to 5000 Kelvin for commercial circle linear light The 3000 Kelvin presents a warm yellow light suitable for creating a warm and comfortable atmosphere. The 4000 Kelvin presents for creating a natural white light, it is suitable for ordinary indoor environments.and the 5000 Kelvin presents a cool white light, it is suitable for environments that require a calm atmosphere.

Overall, Most of contries have certain requirements for the Color Rendering Index, Uniform Glare Rating and Correlated Color Temperature to ensure that office led light can provide comfortable and natural lighting effects in commercial lighting environments. When you purhase led lamps for commercial applications, it is necessary to consult professional manufacturers or designers.
