When the semiconductor industry entered in the world of lighting they came with their “chip” mindset: show off the technology, share the specs and developers will do the rest. Of course, this has not been the case for the lighting industry which has a decidedly “analog” mindset…
With modern glazing systems and sophisticated designs that minimize glare issues, daylighting for industrial buildings is making a strong comeback.
The amber glow of the New York City streetlight is going away. In an energy-saving effort, the city plans to replace all of its 250,000 streetlights with brighter, whiter, energy-saving, light-emitting diode fixtures in one of the nation’s largest retrofitting projects, Mayor Michael R. Bloomberg and the transportation commissioner, Janette Sadik-Khan, said in a news conference on Thursday.
Shortly after launching a line of Great Value LED lightbulbs for less than $10 at all U.S. stores, Walmart announced last week that it will open its first 100 percent LED-lit store as part of the company’s push for nationwide adoption of the energy-sipping bulbs.

And while the emergence of LED-based solid-state lighting (SSL) is spoken about frequently, it is not clear that people understand that LED lighting is more than just an efficient light source.
Lighting used to be straightforward. Bulb type, fixtures, lighting levels, and controls had been chosen (with or without you) during design and construction of the building. As an occupant, you got to tag along and buy replacement bulbs with almost no ability to change or adapt to new needs and technologies.
