LEUKOS — A new article advocating for high color rendering in consumer lighting products and the policies that support their adoption is now available.  The paper is a collaboration between CLTC, the University of British Columbia and the National Research Council of Canada.

The article focuses on the tradeoff between color rendering accuracy and lamp efficiency to show that high color rendering accuracy is appropriate and, contrary to a common misconception, does not intrinsically require greater electrical energy consumption.

Exterior lighting for streets, roadways, parking lots, and other outside sites represents nearly 10% of the electricity consumed on military bases. Lighting in these areas typically consists of high pressure sodium or sometimes metal halide lamps that are normally controlled by photo-sensors located centrally or sometimes on each fixture. This limited functionality includes turning the lights on in the evening and off in the morning regardless of occupancy levels, thereby consuming more electricity than necessary.

CLTC is conducting research into developing technological and market-based approaches that will help increase deployment of energy-efficient technologies in existing multi-tenant light commercial (MTLC) buildings in California. MTLC buildings are single-story commercial buildings with between two and 25 tenants,  less than 150,000 square feet in size, and a power load less than 499 kilowatts.

The results from the market survey will help CLTC researchers identify which technologies and strategies to focus on in developing incentive programs to encourage their adoption.

The California Lighting Technology Center’s 2013 Outdoor Lighting Guide for Title 24, Part 6 compliance is designed to help builders, lighting industry professionals, and others navigate the nonresidential outdoor lighting portion of California’s Building Energy Efficiency Standards. The new standards, which took effect July 1, 2014, include updated requirements for retrofit standards, lighting controls, and uplight and glare limits.
