Color Rendering Index – What Is CRI?
A color rendering index (CRI) is a quantitative metric of the ability of an artificial light source (i.e. LED, Fluorescent, Halogen, Incandescent, etc.) to accurately reveal the colors of a subject in comparison to a natural light source. A CRI of 90 means that the artificial light source is replicating roughly 90% of the visible color spectrum that the su

Why Art and LEDs Go Together
There’s a lot to think about when it comes to lighting a museum gallery. On the technical design side, there are two main factors to consider: light color temperature, or the warmth or coolness of a light source, and the Color Rendering Index (CRI), or the system used to indicate relative color rendering ability.
Seeing Edible Green with LED Lighting
Leaf it to the horticulturalists to come up with something this big: Harnessing the power and versatility of LED lighting, urban farmers are producing 12,000 heads of lettuce per day for consumer consumption.
Breaking Down Renewable Energy vs Zero-Carbon — and the Role of LED Lighting
