COLOUR RENDERING INDEX (CRI)

A colour rendering index (CRI) is a measure of a light’s ability to accurately render the colours of various objects faithfully in comparison with a natural or standard light source.

It is graded on a scale from 0 to 100, with higher values indicating better colour rendering capabilities. Colours of objects illuminated by light sources with lower CRI ratings may appear less vibrant than those with a higher CRI value. 

A CRI rating of 80 or higher is recommended for indoor lighting, especially in areas where colour precision matters, such as art galleries or retail stores.

Most LED bulbs sold today are typically at least 80 CRI, and this CRI value is generally acceptable to most people.

Choosing the Right CRI Rating:

When selecting lighting fixtures, it is important to consider the appropriate CRI rating for the intended application. In spaces where colour accuracy is crucial, such as art galleries or photography studios, a CRI rating of 90 or above is recommended. For general lighting purposes, a CRI rating of 80 or higher is typically sufficient.

Importance of CRI Rating in Lighting:

Accurate Colour Representation: CRI rating is essential for accurate color representation under specific lighting, such as in retail stores, art galleries, and residential spaces. It creates visually appealing and immersive environments, making colors appear as they should. High CRI lighting sources enhance color accuracy, resulting in vibrant and lifelike surroundings.

Visual Comfort: High CRI lighting improves visual comfort by enhancing color rendering. Accurate color representation allows our eyes to perceive details, textures, and contrasts more effectively, leading to better visual acuity and reduced eye strain. This overall improvement in comfort helps minimize the potential for visual fatigue.

Task Performance and Productivity: Proper lighting is crucial for task performance and productivity in work environments. High CRI lighting sources improve visibility and color differentiation, which are beneficial for activities like reading, writing, and intricate tasks that rely on accurate color perception. Employees working in well-lit spaces with high CRI lighting tend to exhibit increased focus and productivity.

Safety and Security: Lighting is vital for safety and security in various environments. Industries like manufacturing, healthcare, and transportation rely on accurate color rendering to identify warning signs, safety indicators, and potential hazards. High CRI lighting improves visibility, allowing for swift and precise recognition of objects and surroundings, thus minimizing the risk of accidents.


Take Away

It’s also important to note that while a high CRI is desirable, it’s not the sole factor to consider when choosing lighting. Other factors such as color temperature and lumen output also influence the lighting's appearance and functionality.
