Happy Holidays and Happy New Year from LightNOW.

Two more educational videos from Philips Lighting today. Back to basics … This video describes the lumen method and how it’s used to determine average light level. This video describes how to calculate light level at a given point by applying the inverse square law.

The DesignLights Consortium™ Premium classification demands higher-performance requirements for luminaires and retrofit kits related to efficacy, lumen maintenance and integral controls. EYE Lighting has published a guide here.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy As we approach a holiday that’s all about gratitude, I’d like to take this opportunity to express my personal gratitude to Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano.

The Nuckolls Fund for Lighting Education, an endowment fund in support of college-level programs that inspire students with an understanding of light in architecture, has issued a call for proposals. E ach year, the Fund solicits proposals from colleges and universities for innovative educational ideas consistent with the Fund’s objectives, and awards grants after rigorous [...]

Luxo’s Split doubles the light output of the typical task light for larger, more demanding applications. The aluminum luminaire features two 6W LED modules, each positioned at 30 degrees for wide light distribution of desktops, while the luminaire head itself remains parallel to the work surface. Dimmable, available with integrated PIR occupancy sensor. Click here [...]

A new, efficient light-harvesting system based on the principles of natural photosynthesis has been developed by researchers at Tokyo Tech. Scientists have long been trying to emulate the way in which plants harvest energy from the sun through photosynthesis. Plants are able to absorb photons from even weak sunlight using light antennae made from chlorophyll [...]

Maury Wright, editor of LEDs Magazine, had an interesting editorial that started the November 2014 issue. Focusing on color-tunable white light and new form factors, he says LEDs are beginning to realize vast transformative potential, though there’s still work to be done. Of particular interest is what we know about light’s impact on human health, [...]

New York Governor Cuomo recently signed into law the “Healthy, Safe and Energy Efficient Outdoor Lighting Act,” which establishes requirements for outdoor lighting installed by state agencies. The bill requires the use of properly shielded luminaires to prevent unnecessary up- and side-lighting, thereby reducing light trespass and sky glow. The bill also states that installations [...]
