Stress Study

New research from California Lighting Technology Center (CLTC) in collaboration with the Center for Mind and Brain has revealed that ambient lighting can play a critical role in how we recover from stress. Backed by Toyota Boshoku America, Seoul Semiconductor, and Color Kinetics, the study involved more than 100 participants undergoing a stressful social scenario—delivering a speech and performing math in front of masked judges in white coats. The team, led by  CLTC researcher Jae Yong Suk and Dr.

Sunlike LED Full Spectrum

New testing at the California Lighting Technology Center highlights the potential of SunLike lighting as a strong alternative to traditional LEDs. The results show that this technology closely replicates natural sunlight, offering benefits in both energy efficiency and visual comfort. With its ability to enhance lighting quality while reducing power consumption, SunLike is emerging as a promising option for various applications.

Energy Code Lighting Language Cleanup Initiative

The California Lighting Technology Center, in collaboration with Southern California Edison, RMS Energy Consulting LLC, and the California Energy Alliance, are establishing a working group of industry stakeholders to help develop recommendations that will simplify and clarify the nonresidential lighting and lighting controls language contained in the 2022 Title 24, Part 6 Building Energy Efficiency Standards.

Renewable Energy & Advanced Lighting Systems for Grid-Connected Exterior Applications

In many communities, exterior lighting operates from early evening through early morning—times when renewable energy generation is minimal. Consequently, most exterior lighting relies on carbon-dense fossil fuels, contributing significantly to greenhouse gas emissions, poor air quality, water pollution, and land degradation. Additionally, outdated and low-quality exterior lighting, characterized by poor color, inappropriate light distribution, and inadequate light levels, has been linked to increased crime rates and reduced physical activity.

Evaluating Opportunities in Advanced Daylighting Retrofits

Interior lighting remains a large component of electricity use in non-residential buildings. In California, electric lighting has both a direct effect on peak load, and an indirect effect by increasing cooling requirements during summer peak hours. Effective daylighting combined with electric lighting dimming controls can directly offset electric lighting energy by reducing lighting levels when necessary to reduce the load on the cooling system.
