Glare and UGR – a short descriptionScreenshot 2014-09-26 14.00.27

Glare might seem like a subjective term, but it is actually calculated using a precise formula. Essentially, this formula measures the luminance of a lamp divided by the background of visible luminance from the room. This number is called the Unified Glare Rating, or UGR, and it ranges from 5 to 40. The lower the number, the better. For example, a low UGR of 10 means the glare is so discreet it will go unnoticed, while UGR of 30 will definitely cause distraction.

Here are some links to websites explaining glare and UGR (Unified Glare Rating) in easy to understand terms:

DOE publishes CALIPER Snapshot Report on LED MR 16 Lamps

The U.S. Department of Energy’s CALiPER program has released a Snapshot Report on Screenshot 2014-03-09 16.08.33MR16 lamps, which utilizes the LED Lighting Facts® program’s extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products.

Among the key findings:

•Few MR16 lamps currently listed by LED Lighting Facts are comparable to a 50W (12V) halogen MR16 lamp. Of the small subset of MR16s that provided data for beam angle and center beam intensity, only one would meet the minimum ENERGY STAR® center-beam candlepower criterion for equivalence to a 50W halogen MR16 at the same beam angle (40°).

•While the overall number of MR16s listed by LED Lighting Facts has increased slightly over the past three years, they now account for only 4 percent of all listed products, compared with 11 percent three years ago; and the mean efficacy for newly listed LED MR16s has shown minimal change over the past two years.

•Both lumen output and input power have increased steadily in recent quarters. The net result has been little change in luminous efficacy.

•On average, the MR16 lamps listed by LED Lighting Facts have slightly better color quality than other lamp types, with a higher percentage of MR16 lamps having a color rendering index above 90.

•As with all categories, there is substantial variability in the performance of LED MR16 lamps listed by LED Lighting Facts. Specifiers and consumers should evaluate each product on its own merits.

Leslie T. Chang: The voices of China’s workers

2012-09-16_080623 leslie changIn the ongoing debate about globalization, what’s been missing is the voices of workers — the millions of people who migrate to factories in China and other emerging countries to make goods sold all over the world. Reporter Leslie T. Chang sought out women who work in one of China’s booming megacities, and tells their stories.

Harald Haas: Wireless data from every light bulb

Harald Haas

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread.

Harald Haas is the pioneer behind a new type of light bulb that can communicate as well as illuminate – access the Internet using light instead of radio waves.

LEDinside: China’s residential lighting market surpasses US$ 800M in 2013

LED Lighting Market 2012

Starting from 2012-2014, bans on incandescent lights has led to the gradual entry of LED products in the residential lighting markets, according to a latest search report by LEDinside, a research division of TrendForce. Improved LED luminous efficacy and lowered LED product prices contributed to higher consumer acceptance levels and rising penetration rates. Japan was the largest LED residential lighting market in 2012, followed by Europe and North America. However, China’s residential lighting’s global market share is also growing.

LED LIFETIME AND RELIABILITY

LED Reliability

Long life has been billed as a key advantage of LEDs, but understanding and communicating how LED products fail and how long they last can be challenging. While LED-based products hold the potential to achieve lifetimes that meet or exceed their traditional counterparts, manufacturer claims can be misconstrued by users who do not fully understand LED product failure mechanisms or the difference between lifetime and reliability
