LED + SSL

Guest post by Jim Brodrick, Department of Energy A few weeks ago, writing about the CALiPER Round 11 testing results, I mentioned that although LED linear replacement lamps are improving, especially in terms of their efficacy, we’re still seeing major performance challenges in the areas of total light output, light distribution, color quality, and reliability.

ENERGY STAR is a voluntary labeling program designed to help consumers identify energy-efficient, cost-effective products. To earn the label, a manufacturer’s product must meet strict efficiency and performance criteria established by the Federal government. On Aug. 31, 2010, the final ENERGY STAR criteria for integral LED replacement lamps became effective.

The pedestrian-scale Sera LED by HessAmerica features a low-brightness LED optical system and tool-less access to a field-replaceable light engine.

The Yas Hotel, on Yas Island in Abu Dhabi, was conceived as two towers connected by a bridge and united by a stunning glass and steel grid-shell element. The hotel’s sweeping grid-shell element, built by Austrian specialist Waagner-Biro, illuminates at night using more than 5,000 custom LED fixtures and a sophisticated control system, the result of an intensive design effort by Arup Lighting, who was engaged by Asymptote to create a lighting solution for both the iconic canopy and the hotel’s exterior.

Specifically, how to protect yourself and your clients from bad product. This article, which I authored for the October issue of TED Magazine, the official publication of the NAED, covers standards and testing, labeling and awards programs that can be used to find LED products that are most likely to provide reliable performance while saving [...]

Litecontrol has unveiled the L20, the debut LED luminaire for Litecontrol, designed to functionally provide higher light output and efficacy than a similar linear fluorescent luminaire.

Lighting Science Group’s PROLIFIC series LED street lights will soon line the streets of Salt Lake City, Utah. Compared with traditional high pressure sodium (HPS) street lights, the PROLIFIC LED series street lights are 50% more efficient, provide more uniform light distribution, increase light levels, and will save Salt Lake City tens of thousands of [...]

The National Electrical Manufacturers Association (NEMA), a member of the Global Lighting Forum (GLF), has announced an initiative to coordinate and promote LED (light emitting diode) technology on a global level. In order to accelerate the uptake of LED lighting, GLF held the inaugural meeting of its LED Working Group recently in Shenzhen, China. In [...]

I authored an article for the October issues of TED Magazine, the official publication of NAED, covering developments in LED modules, which promise faster to market, easier to service, more durable LED luminaires. Read the article here.
