Product Monday: Dart by Focal Point
Focal Point’s Dart is a direct/indirect linear suspended luminaire with a wall-mount companion. The luminaire uses LED lamping at up to 1,250 lumens/sq.ft. (106 lumens/W) based on five standard lumen output levels, with customizable levels available via factory-programmable drivers. Its Gradient Optic feature, a saw-tooth reflector that diffuses the edges of the indirect distribution, prevents [...]
Jim Brodrick on What’s New in OLED
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 Greetings from Rochester, NY, where the OLED community — with some facilitating by DOE — is meeting to share updates on the efforts of a new OLED Coalition, explore basic science and [...]
The Lumen Method and Point by Point Calculations Explained
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.
EYE Lighting Publishes Guide to DLC Premium and Standard Classifications
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.
Jim Brodrick on the Nobel Prize in Physics

In awarding the three [...]
The Nuckolls Fund for Lighting Education Issues Call for Proposals
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 [...]
Product Monday: Split by Luxo
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 [...]
Light Harvesting: Mimicking Photosynthesis with Artificial Leaves
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 [...]
