A Look At The Color-Mixed White LED Future

In February 2022, the US DOE released its 2022 SSL Research & Development Opportunities report. While the report covers many promising directions for SSL R&D, one of the most significant evolutions predicted for LED light sources is the shift from phosphor-converted white LEDs (PC-LED) to color-mixed white LEDs (CM-LED).

2022 State of the Cannabis Lighting Market Finds Record LED Usage

Cannabis Business Times released the seventh-annual “State of the Cannabis Lighting Market” report. Results from the 2022 report demonstrate the increasing usage of LED lighting technology across all growth stages of cannabis cultivation. For the first time ever, at least 70% of study participants from commercial indoor or greenhouse operations with supplemental lighting used LEDs in cannabis propagation, vegetation and/or flowering stages.

Nearly All Mental Health Disorders Correlate With Circadian Rhythm Disruption

University of California, Irvine (UCI) researchers conducted a thorough examination of peer-reviewed literature on the most prevalent mental health disorders and found that circadian rhythm disruption (CRD) is present in nearly all of them. However, correlation is not causation, so it is not clear if the mental disorders cause circadian disruption, if circadian disruption causes mental disorders or both in a positive feedback loop.

IDA Releases 2022 State of the Science Report On Light Pollution

The International Dark-Sky Association (IDA) released the “Artificial Light at Night: State of the Science 2022” report, earlier this month. It is a high-level overview of the best scientific understanding of how artificial light at night affects the nighttime environment. It finds the world transformed by electric light in less than 150 years since its introduction.
