Emerson Launches LED Luminaire for Hazardous Locations
EMR recently unveiled its state-of-the-art gasketed and enclosed Light Emitting Diode (LED) luminaire — Appleton Contender LED. Taking the company’s operational efficiency, employee safety and lighting performance a notch higher, luminaire will likely bring maintenance and energy savings up to 65% in difficult low clearance areas like catwalks, tunnels, walkways and stairwells. So far, High-Intensity Discharge (HID) luminaires were used as the major light source in chemical processors, oil and gas facilities, and other hazardous locations. However, at the moment, Emerson’s latest LED luminaire is viewed as a more cost-effective solution than the existing HID luminaires offered by one its major rivals. The Appleton Contender LED is highly useful for retrofit applications and is equipped with unique accessories like a safety cable, angled reflector, globe guards and visor.

LED-ifying A Guitar, Part Two
An electric guitar is all about stage presence. Need to be cooler than a single guitar? No problem — there are double neck guitars. Need to be cooler than that? No problem, the guy from Cheap Trick has a five-neck guitar. Need to be cooler than that? Robbie Robertson played a guitar with an extra mandolin neck on The Last Waltz. Where do you go from there? Obviously, the solution is putting a TV in your guitar with a boatload of individually addressable LEDs in a guitar. That’s what [Englandsaurus] is doing, and the build thread is now getting into how to turn a bunch of LEDs into a display.
ECPPS eyes LED lighting project
Elizabeth City-Pasquotank Public Schools officials are considering a proposal to covert all school facilities to LED lighting as a way to save money on energy costs. Chris Nelson and Ted Vogel of Helios Energy attended a committee meeting of the Elizabeth City-Pasquotank Board of Education Monday afternoon. Helios has proposed a service contract allowing it to install and maintain LED lighting for some 1.2 million square feet of space at ECPPS facilities. According to its proposal, Helios would cover the upfront costs of installing the LED lighting and then contract for maintaining the lighting over a designated period — likely seven years. LED, or light-emitting diode, lights generate as much as twice the amount of light for the same amount of energy.

City's LED upgrade provides music
As many patriotic residents noted, the recent Veterans Day parade through downtown St. Cloud not only introduced people to a new route with new vantage points, it also included new sounds. Thanks to the city's recently upgraded LED lighting system, patriotic music added a distinctly American audio ambiance along much of the route. The system resulted from a $7 million street light improvement project, which the city began installing in 2016. The LED lights are expected to save about $600,000 a year, meaning the cost of the project should be paid back in 12 years, city officials said when the upgrade began.
Efficiency breakthrough for radical LEDs
Light-emitting devices made from organic materials have the potential to be thin, flexible and lightweight, and might therefore be used in a variety of applications — including foldable display screens, ‘smart’ wallpaper incorporating digital devices, and windows that could be converted into illuminated panels at the flick of a switch. The efficiencies of other types of OLED are generally limited by quantum-mechanical effects, but radical-based OLEDs (ROLEDs) don’t have this constraint, owing to the electronic state of the radicals. The authors’ ROLEDs have the highest emission efficiency obtained so far among LEDs that emit light in the deep-red and infrared regions of the electro-magnetic spectrum.
Augusta buying into LED technology for savings
Augusta officials are planning to take control of their streetlights. They plan to buy the nearly 2,000 streetlights from Central Maine Power and convert them to more efficient LED lights. The move could save the city $168,000 to $300,000 a year. Augusta, like many Maine municipalities, currently leases the lights along its city streets from CMP.

You’d never guess these gorgeous lamps are made from bioplastic
High-end lamps with thin elegant forms are made of metal. But a new lighting series from the London-based design studio Industrial Facility is composed of a bioplastic derived from castor oil. The lamp, called Pastille, is simple by design: just a hand-sized circle suspended from a single post. Even its insides contain only the bare essentials, with a single LED hidden inside the round disk. A mirror and plastic diffuser help that single LED do the work of a full array, while making the lamp more energy efficient.
Thwarting LED cost erosion, high-value automotive sector is driving revenue growth
According to market research firm Yole Développement, lighting is becoming the new photonic hub, with the ‘LEDification’ of vehicles set to propel automotive lighting revenues to $37.3B by 2023. With the integration of light emitting diode (LED) technology, lighting has evolved from a basic, functional feature to a distinctive feature with high-value potential in automotive. Indeed, LED technology has given manufacturers the opportunity for strong differentiation via lighting design and additional functionalities. This is particularly true for exterior lighting. The integration of new solid state lighting (SSL) technologies is transforming automotive front lighting and rear combination lighting (RCL) systems and their applications, offering more design flexibility, increased efficacy, and intelligent functionalities.

What you need to know about LED lamps
LED lamps can offer 50,000 hours of use if they are engineered correctly according to Futronix.com. You may have seen LED lamps referred to as ‘Solid State Lighting’. This is because they are manufactured from solid materials. Another key benefit of using LED lamps is that they light instantaneously, so you don’t need to wait for a warm-up period to elapse. They can output up to 135 lumens per watt and aren’t affected by cold temperatures. You can also move the bulbs to direct light where you want it. One thing you really do need to be aware of is the fact that not all LED lamps can be dimmed. You must check that the lamp is actually dimmable before you make a purchase, so look at the packaging before you proceed. Even if the packaging does state that a lamp is dimmable, this doesn’t always mean that the performance will be fantastic.

LED lighting could result in more indoor farms cropping up
Mike Zelkind stands at one end of what was once a shipping container and opens the door to the future. Thousands of young collard greens are growing vigorously under a glow of pink-purple lamps in a scene that seems to have come from a sci-fi movie, or at least a NASA experiment. But Zelkind is at the helm of an earthbound enterprise. He is chief executive of 80 Acres Farms, with a plant factory in an uptown Cincinnati neighborhood where warehouses sit cheek by jowl with detached houses.
Zelkind is part of a radical shift in agriculture — decades in the making — in which plants can be grown commercially without a single sunbeam. A number of technological advances have made this possible, but none more so than innovations in LED lighting.
This LED faucet light changes color based on water temperature
Sometimes the simplest little gadgets can be so cool, and that’s exactly the case with the DLAND RC-F03 Colorful LED Water Faucet Attachment. This little device screws into any standard tap in your sink and water flows through it normally. But here’s the cool part: it has different color LEDs inside that automatically turn on when water flows through it! Red means hot, blue means cold, and green means just right.

Philips Hue Signe Floor Lamp
Sometimes, when a child misbehaves, their parent will make them stand and face the corner in a time-out. That's sort of what it was like testing out the new Philips Hue Signe floor lamp. Available as a 24-inch table lamp for $160 (about £125, or AU$220), or a 58-inch floor lamp for $250 (about £195, or AU$345), the new fixtures are basically vertical wands of light designed to spread color across your walls. And, in fairness, both Signe fixtures behaved perfectly well as I tested them out -- but I also didn't really know what the heck I was supposed to do with the things.
LED Replacement Lamp and Lighting Controls from Current by GE

Machine learning algorithm finds the best LED phosphor in list of 100,000 compounds
A machine learning algorithm that can swiftly identify the most desirable LED phosphor host compound out of a database of almost 120,000 materials has been developed by researchers in the US. Efficient enough to run on a PC, the program was created by Jakoah Brgoch and colleagues at the University of Houston and has predicted the relevant properties of a highly efficient, thermally stable compound in well under a minute. The team’s algorithm could soon be used to speed up the discovery of new materials for use in commercially competitive LEDs. Typically, LEDs are composed of an inorganic, luminescent “phosphor” material, doped with small quantities of rare earth elements. The interactions between phosphor hosts and the rare earth dopants are a strong indication of an LED’s performance.

Eaton, Dolphins Unveil Ephesus LED Sports Lighting System At Paladin Stadium
Representatives from the Miami Dolphins, power management company Eaton, the Broward County School District and South Plantation High School, officially flipped the switch on Saturday night, turning on the new state-of-the-art Ephesus LED sports lighting and control system awarded to South Plantation High School’s Paladin Stadium as winners of the community programming initiative – “Light Like the Pros.”
The capabilities of the system were demonstrated for the crowd during a half-time ceremony of the South Plantation versus Plantation annual rivalry game on October 27, featuring Twan Russell of the Miami Dolphins, Laurie Green representing Ephesus Lighting and NGU Sports Lighting and Christine Henschel from South Plantation H.S. After sending the stadium into complete darkness, with the push of a button, fans were treated to an electrifying light show more familiar to the fans at Hard Rock Stadium than a high school football venue.
History of White LEDs
Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light. Of course, that means that incandescent light bulbs are more efficient at producing heat, and as the days get shorter, and the nights get colder, somewhere, someone who took the leap to LED lighting has a furnace that’s working overtime. And that someone might also wonder how we got here: a world lit by esoteric inorganic semiconductors illuminating phosphors. The fact that diodes emit light under certain conditions has been known for over 100 years; the first light-emitting diode was discovered at Marconi Labs in 1907 in a cat’s whisker detector, the first kind of diode. This discovery was simply a scientific curiosity until another discovery at Texas Instruments revealed infrared light emissions from a tunnel diode constructed from a gallium arsenide substrate.

Invisible LEDs light up Beijing landmark
Signify, formerly Philips Lighting, has installed architectural lighting into the façade of one of Beijing’s tallest buildings, illustrating the growing trend in China to make cities more attractive and liveable using the latest in connected lighting. China World Trade Centre’s (CWTC) Tower B is a new hub for commerce and tourism in Beijing’s central business district. The 300m tall building is the latest addition to the CWTC, a growing mixed-use campus and home to some of China’s leading companies.
An LED 'Filament' Bulb: Not a Contradiction
For those who miss the appearance and glow of a filament-based bulb, this LED bulb technology may offer the best of both worlds. It’s not news that the venerable incandescent-based bulb with its glowing filament is on the way out. Due to technical advances, regulatory mandates, and substantial cost savings, compact fluorescent lamps (CFLs) and especially LEDs are taking over the lighting world in residential, commercial, and industrial settings. Still, there are many who long for the glow of that filament. Reasons vary: For some, it is nostalgia for their youth; for others, it’s the hip, retro factor; and for others, there’s something almost primal about that glow, reminiscent of elemental fire (the glowing filament is certainly analogous to that).

100-year-old ‘lamp company’ in Old City turns off lights one last time
After sitting at the same oak rolltop desk as his father and grandfather and running the same specialty hardware distributor of lighting products that has been in the family for more than a century, Newton Gold knew the business landscape had changed. Many of his customers, mostly hardware retailers, have shuttered their stores and Gold, 88, said he didn't want to hustle to find new ones. He saw his children pursuing different careers. Even a former customer talked of how the economy had changed to rely more on mass merchants than local business owners.
Some Washington County cities running into snags as streetlights switch to LEDs
Many communities across Washington County are making the switch to LED lights from the traditional high-pressure sodium lights that have lined roadways for decades. While some communities are experiencing growing pains involved in changing to the more energy-efficient, brighter LED lights, the color and cost of making the switch aren’t enough to stop cities like St. George, Ivins and Springdale from moving forward with plans to replace every streetlight with LEDs. The city of St. George has already replaced a “significant amount” of streetlights in the city with LED bulbs over the past three years with no signs of slowing down until all the streetlights in the city are LEDs, said Rene Fleming, manager of energy and water customer services for St. George.
