LD+A – High dynamic range (HDR) imaging, originally developed and used for research purposes, now is becoming a consumer term as several consumer cameras and even mobile phones, such as the latest version of the iPhone, include some form of HDR capabilities, mainly for improved photography. As digital cameras and software become mainstream, so does the consideration of HDR imaging in lighting practice, pointing away from using workplace illuminance as a sole determining metric for design.
Enlighten – Concerns about energy efficiency, coupled with a growing awareness of climate change, have heightened interest in efficient lighting as an effective strategic venture for our country. Given the unprecedented investment directed at public entities for “efficiency opportunities” and the lack of a clear vision related to “what should be done,” there is mounting concern related to the ultimate value of this investment and the ability to achieve sustained and deep energy savings.
LD+A – Concerns about energy efficiency, coupled with a growing awareness of climate change, have renewed our national interest in reducing energy use and the associated carbon footprint. The understanding is that this investment will achieve deep and sustained energy savings in infrastructure for our public spaces. One target is re-lighting municipal roadway applications, focusing on the ubiquitous streetlight.
LD+A – The strategy is to foster the development of high-efficacy light sources that achieve, as much as possible, interchangeability with incandescent lighting, in terms of compatibility with electrical infrastructure and with popular lighting expectations. This article is a summary of CLTC research aimed at developing a technology-neutral Super Lamp specification for replacement of incandescent sources in the residential sector.
LD+A – The New York Energy Conservation Expo (NYECE) is dedicated to displaying energy conserving devices and systems on a year-round basis. The director of NYECE met with CLTC director, Michael Siminovitch, to discuss conservation, lighting, and collaboration.
Sacramento Bee – The bad economy is prompting Americans to save instead of spend. But spending less makes the economy even worse. One small way to help break the cycle is to invest in efficiency. Done right, it allows you to save and spend at the same time.
Sacramento Bee – For Michael Siminovitch, if the design is right, energy efficiency will follow. Siminovitch directs the California Lighting Technology Center in Davis, a partnership of the University of California, Davis, and the California Energy Commission as well as utilities and industry. He talked with The Bee about the future of lighting and his approach to illumination.
Fast Company – The United States generates more energy than any other country in the world -- and wastes more than half of it. Efficiency, it turns out, can be a rich resource. Those riches are being exploited by a kind of alchemy that combines science with business. Efficient technologies, from sensor-equipped LED lighting to smart electric meters, are flowing at a brisk pace out of labs, attracting capital from Goldman Sachs and Silicon Valley VCs, and support from the likes of Walmart, Chevron, Samsung, and California's major utilities.
Lighting Controls Association – The California Lighting Technology Center (CLTC) organized a study in eight private offices at the University of California, Davis in 2008 to attempt to generate useful data related to these questions.
Macworld product review – Full Spectrum Solutions' Berkeley Lamp II provides provides both downward-focused task lighting and upward-facing ambient lighting with two independent, dimmable fluorescent bulbs. The energy-efficient office lighting solution is also designed to prevent eyestrain and glare.
