China has canceled its harsh entry restrictions that were part of its Zero Covid policy. The new policy is called the “0+3” policy. Mainland China is expected to be fully open to entry on January 9, the start date of the new “0+3” policy. Overseas visitors to China will only need to quarantine for 3 days, and will no longer need [...]

The recently released 2018 Commercial Buildings Energy Consumption Survey (CBECS) by the U.S. Energy Information Administration (EIA) found that the total floorspace in commercial buildings had increased but energy consumption had not, compared with the last survey analyzing commercial building energy use, in 2012. This difference indicates that the consumption per square foot (energy intensity) had decreased, [...]

LED luminaires have been getting smaller for a long time, but Minimis takes it to extremes, claiming the smallest luminaires in the world. A good example is their NICK luminaire, measuring in at less than a square inch. The Florida-based company describes NICK as a micro-minuscule luminaire, and the world’s smallest recessed directional luminaire designed [...]

Roku has expanded into the smart home space with white and colored smart bulbs, a Roku lightstrip, Roku smart plug, Roku indoor and outdoor security cams, Roku home video doorbell & chime, and a Roku panning cam. The products look similar to the Wyze‘s Cam v3, Cam Pan V2, Bulb Color and other products. The [...]

Earlier this week, the US Department of Energy (DOE) proposed a new energy efficiency standard for General Service Lamps (GSL). The new standard would impact an enormous variety of lamps, including A-lamps (CFL & LED), directional R & PAR lamps, and LED tubes (TLEDs). Right now it is still a proposal, but odds are good [...]

The DLC compiled a list and interactive maps of locations with published outdoor lighting ordinances to mitigate light pollution. These maps show states, provinces, and cities/towns, throughout Canada and the U.S., with outdoor lighting ordinances. States and provinces shaded blue have a statewide/provincewide policy. The round markers indicate cities, towns, and counties with an ordinance. [...]

The most recent email newsletter from LD+A, their E Report, was sponsored by the Washington Metropolitan Area Transit Authority (WMATA), with the Request For Information (RFI) graphic above. WMATA is asking lighting design firms to consider responding to their RFI. The image links to the WMATA Procurement and Contracting web page, here. The deadline for [...]

Tony Esposito and Kevin Houser published a new study in Scientific Reports demonstrating that CCT is not suitable for predicting the biological potency of light. The experiments utilized a 5-channel LED lighting system to show that significant variation in CS and EML/mEDI exists at any fixed value of CCT and photopic illuminance. For many years, [...]

LCA Director of Education and LightNOW Founder, Craig DiLouie, recently authored an article explaining how D4i helps standardize luminaire level lighting control (LLLC) as one standardized approach to IoT lighting. By standardizing control and power requirements, D4i makes it much easier to mount sensors and communication devices on luminaires. In addition, intelligent D4i LED drivers inside the luminaire [...]
