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 [...]

The Biden-Harris Administration, through the U.S. Department of Energy (DOE), released a Notice of Intent, on 11/22/22, announcing $550 million to support community-based clean energy in state, Tribal, and local governments — serving more than 250 million Americans. This investment is through the Energy Efficiency and Conservation Block Grant (EECBG) Program in order to support communities [...]

LEVAR, a leading provider of Augmented Reality (AR) and 3D “View in your space” technologies, and the Lighting Showroom Association (LSA), announce the launch of their partnership platform to bring AR and 3D technologies to the residential lighting and fan industry. Through the LSA Augmented Reality program, LEVAR provides LSA member showrooms and manufacturers with the ability [...]

By 2050, the number of older adults aged 50 and older is expected to double, comprising 20% of the total US population. The overwhelming majority want to age in place, but experts say the current housing stock is ill-equipped to handle those desires. Lighting can be controlled based on motion through simple solutions that only [...]

Quantum-dot LEDs (QD-LEDs) are based on quantum dots (QDs), semiconductor particles just a few nanometers in size. Because of their extremely small size, their behaviour is governed by quantum mechanics. By ‘exciting’ quantum dots with electricity or driving radiation, they can be induced to emit light, the color of which is determined by the size [...]

The US Green Building Council and the International WELL Building Institute have formed a partnership to simplify certifying buildings for both health and sustainability. The USBGC’s LEED certification rates a building’s sustainability credentials, while WELL ratings consider a building’s impact on the wellbeing of people who use it. Both LEED and WELL building certifications have [...]

Ultra Wideband (UWB) is a wireless communication protocol that operates over short distances, much like Wi-Fi and Bluetooth. What makes it different is that the technology operates in the higher frequency bands of radio waves and across a wide bandwidth, hence the name. It has some useful and unique abilities, such as being able to [...]

The field of photocatalysis chemistry is producing important breakthroughs in industrial chemistry. In July, LightNOW reported on a new photocatalyst revolutionizing the conversion of methane into liquid methanol, here. Now Rice University researchers have created a small, LED-powered device that converts ammonia to hydrogen on the fly Ammonia might carry hydrogen exceptionally well, but if [...]
