Signify buys 51% of Chinese LED lamp maker
In an effort to cut manufacturing costs, gain control of supply, and protect intellectual property, Signify is acquiring 51% of a Chinese LED lamp and luminaire provider, while announcing another quarter of slowing sales but rising profits amid ongoing restructuring. The world’s largest lighting company did not reveal how much it paid for the stake in privately held Zhejiang Klite Lighting Holdings Co., Ltd., a company which sells private label and OEM goods to companies mostly outside of China.
Build Your Own LED Glow Poi
Spinning poi is an entertaining pastime, and LEDs can make a great addition to the experience. MilanDer built some LED poi of their very own, using a few maker staples along the way. A 3D printed enclosure is first created, using “clear” PLA that in practice produces translucent white parts. This acts as a great diffuser for the APA102 LEDs inside. The LEDs are driven by an Arduino Pro Mini, which is fitted inside the enclosure along with a buck-boost converter, lithium battery and charge board. Finally, a strap is added to allow the poi to be spun easily by the user.

How Lighting Can Impact Our Mood and Behaviour
Most people don’t put much thought into how lighting impacts their mood and mental health. For instance, we tend to feel drowsy and less motivated on rainy, cloudy days and more energetic and upbeat on sunny days. We are responding to the psychological effects of lighting which is what changes our mood. However, how we feel and respond to light extends beyond the natural sunlight we receive. The lights and lighting fixtures in our home and work environment can have a deep impact on our mood, alertness, energy, productivity, and creativity. What are the best types of lighting then? Here are the different ways in which our mood, behaviour, and overall mental health are influenced by the lighting around us.
Current redefined, again
This LUR refit fixture is the first product that Current’s new owner AIP showed when it unveiled new wares two months ago at LightFair, hailing the product for a quick installation time. AIP seems intent on making sure an industrial image gets equal play with digital. Digital is still on the menu, though. This LUR includes “photo banding” technology that Current says is more precise than Bluetooth for indoor positioning in retail.

Solar Street Lights Improve Quality of Life in Indian Villages
A government program in India helps provide solar-powered street lights to rural communities. Solar lighting is bringing changes to many areas, including the village of Balla, near the Himalayas in the northern state of Himachal Pradesh. In the past, many villagers never left homes after the sun went down. The reason: the streets usually went completely dark at night. “We used to be scared. This is a lonely area and wild animals used to come,” villager Umesh Chandra Awasthi told VOA.

Neutrogena Recalls Light Therapy Masks, Citing Risk of Eye Injury
Over the last several years, light-emitting therapy masks intended to treat acne have streamed into the marketplace and onto Instagram, filling feeds with pictures of people that resemble space-age hockey goalies. Neutrogena’s version of the product, which the company said would kill acne bacteria and fight “inflammation,” cost between $30 and $40, making it one of the more affordable masks on the market. But earlier this month Neutrogena issued a recall of its masks, citing a “theoretical risk of eye injury” to a subset of people who had underlying eye conditions or were taking medicine that made them sensitive to light.
Advanced Efficiency of Perovskite LEDs Achieved with Interlayer Reaction
Scientists at Linkoping University working with colleagues from China have shown how to achieve efficient perovskite LEDs. In an article published in Nature Communications, they provide guidelines on fabricating high-quality perovskite light emitters for high-efficiency perovskite LEDs. Since solution-processed perovskites contain large amounts of defects, which are mostly halide vacancies, efficient control of the perovskite crystallinity is required for high-performance optoelectronic devices. The research group at LiU, under the leadership of Senior Lecturer Feng Gao, in collaboration with scientists from Nanjing Tech University, and Soochow University in China, has now studied how the precursor components and the interfaces affect the crystallization process of perovskites.
Brooklyn eyes completion of main street and rec center LED light conversion projects
The conversion of Brooklyn’s main thoroughfares to LED lighting is nearing completion. "Using a little more than $39,000 in NOPEC (Northeast Ohio Public Energy Council) money, we worked with FirstEnergy to replace our street pole lighting to LED," Mayor Katie Gallagher said. "That involves 187 lights on the main roads. It looks like they’ve completed all of Tiedeman Road, all of Biddulph Road and a little bit of Ridge Road."

Current places bets on cannabis lighting in distribution deal
With high hopes for the cannabis market, GE’s former lighting company Current has struck a distribution deal with Hort Americas to sell Current’s latest LED grow light. Current introduced the Arize Element Top Light last month in Amsterdam, billing it as “the industry’s first one-for-one LED replacement for 1000W high-pressure sodium (HPS) products.” Hort Americas is Current’s exclusive North American distributor, and is encouraged by the marijuana prospects for LED technology, which it says yields plants with higher THC and CBD (tetrahydrocannabinol and cannabidiol — the active chemicals in the cannabis plants) than do HPS lamps.
Virginia to implement streetlight changes, introduce ‘warm’ LEDs
Virginia is planning major changes to streetlights with a switch of thousands across the state to brighter LEDs. Though the change — due to be approved by the Commonwealth Transportation Board Wednesday — is projected to save on energy use, it has also raised concerns about additional light pollution that could keep people up at night or impact wildlife. The proposed contract would require “warmer”-colored LEDs in many spots, rather than the extremely white light that has been considered or used in some places, meeting a request of the International Dark Sky Association.

Academics steal data from air-gapped systems via a keyboard's LEDs
The Caps Lock, Num Lock, and Scroll Lock LEDs on a keyboard can be used to exfiltrate data from a secure air-gapped system, academics from an Israeli university have proved. The attack, which they named CTRL-ALT-LED, is nothing that regular users should worry about but is a danger for highly secure environments such as government networks that store top-secret documents or enterprise networks dedicated to storing non-public proprietary information.
An affordable option for a flex-type led light
The LED panel and LED Bowens mount are both familiar form factors of LED lights. In the last two years, we are seeing a third type of LEDs enter the market – the Mat LED, A.K.A Flex-LED. Essentially it is very similar to an LED panel, only instead of the LEDs being mounted to a rigid surface, they are placed on a flexible light, hence the name – Flex light.

Ogden considering new bonds to pay for baseball stadium lighting, other energy conservation projects
Ogden City is considering a new bond measure that would, among other things, fund a major lighting upgrade at Lindquist Field and pay for energy conservation projects around the city. In 1997, revenue bonds totaling $900,000 were issued to finance the acquisition and construction of the baseball stadium. In 2006, the bond was refunded and wrapped with additional bonds worth $2.87 million that went to the construction of the city’s Public Works building. In November 2017, the city issued another bond related to the stadium, totaling $3 million, which has been used to expand and renovate the facility.
Upgrade your yard lighting to LED the smart way
One of the last dumb things in your smart home might be your outdoor lighting. If you want a smart outdoor lighting system for your garden, you could cobble together an array of smart home lighting products from various makers or use products from one brand, such as the Philips Hue outdoor line. But I recommend a different route: Upgrade the bulbs in your current outdoor fixtures to LED and use an outdoor plug adapter to make your garden lights part of your home control tech. You won't get all the bells and whistles possible, but if you can live without nightclub color scenes or speakers built into lights, you'll like the results of my cheap and straightforward upgrade.

Ikea expands TRADFRI HomeKit line with new bulbs, light panels, and more
Ikea has revamped its smart home TRADFRI line, adding new smart bulbs, light panels, and more. The update to the TRADFRI line comes ahead of the rumored launch of Ikea’s HomeKit blinds later this year. As detailed by HomeKit Hero, Ikea has added several new products to its TRADFRI range of accessories. There’s a new filament style light bulb that comes in the A19/E26 size, which retails for $15.99. This bulb offers three different color temperatures, ranging from warm to cold light. It’s rated for brightness of up to 806 lumens. There’s also a new candelabra E12 base color and white light bulb, with 650 lumens of brightness.
Taming LED’s Color Issues
When LED lighting fixtures exploded on the cine, video and television scene, one of the first things that early adopters discovered was that all LED lights weren’t created equal, especially in the area of color rendering. Complicating the problem was that you couldn’t measure color rendering by eyeballing it. “When you look at visible light, it has all the colors of the rainbow, all the way from infrared to ultraviolet,” said Jose Maria Noriega C.A.S., president of professional lighting provider Fluo-Tec. “Of course the eye will try to compensate for color aberrations.”

Epoxy LED Cube Looks Sleek, And Flashes To The Beat
If there’s one thing that’s universally popular in these polarizing times, it’s colorful glowing objects. LEDs reign supreme in this area, and we’re accustomed to seeing all manner of fun flashy devices hit the tips line. Today is no different, and we’ve been looking at Modustrial Maker’s stylish epoxy LED cube. The build starts with the casting of a black epoxy cube, with a cutout near the top in which the LEDs will be installed. A melamine form is used, with aluminium foil tape, caulk and paste wax to help seal it up. After releasing the cast from the form, there were some unsightly voids which were swiftly dispatched, by trimming the block down with a table saw.

A Wall Lamp that Simultaneously Acts as a Clock
The inspiration to design the Reverse Sunclock Multifunctional Wall Lamp emanates from the desire to match two inseparable concepts - time and light. The marriage of those into an object that resembles a clock yet exists as a wall lamp initially sprung from the observation of sun clocks. Shadow and light unite and produce the notion of time. In this case the game between light and shadow applied onto a reverse sun clock half fiberglass half brass gives birth to a hybrid product, a ying yang existence of time and light.
Recreational Cannabis States Turn to LED Grow Lights to Optimize Yields
As commercial cannabis cultivation has exploded throughout the United States, it has encountered several challenges along the way, including a huge spike in electricity use in states that have legalized recreational marijuana. According to a 2016 article by the National Conference of State Legislatures, the summer after Oregon legalized recreational marijuana, Pacific Power in Portland experienced seven blackouts traced to cannabis production facilities.
Forty-five percent of Denver’s electrical “load growth” is for electricity to power cannabis facilities, and as of February 2018, nearly 4% of Denver’s electricity was devoted entirely to commercial cannabis facilities. Much of this power use can be attributed to the use of High-Pressure Sodium grow lights common to the commercial cannabis industry.
In order to reduce both their costs and carbon footprint, commercial cannabis producers have been switching to LED grow lights, like those manufactured by Kind LED.
LED grow lights produce more yield per watt than traditional HPS fixtures while promoting a significant increase to overall quality through their targeted spectrum. Some LED grow lights, such as California based Kind LED Grow Lights, also include IR and UV wavelengths that have been shown to increase the production of oils and terpenes by up to 80%, and produce closer internodal spacing and denser fruits and flowers than other grow lights. They’re able to provide this remarkable increase in quality while using 50% less energy than HPS fixtures.
Also, because LED grow lights produce less heat, they do not need to be air-cooled like HPS lights, eliminating the need for additional fans, which makes them run quieter. Lower light temperatures lead to a much more easily maintained grow environment. Some LED grow lights, such as Kind LED, have an adjustable spectrum light, with individual diodes that can be set to a specific color and in a specific proportion, so that they are able to emit the exact spectrum that a developing plant needs to thrive, with little to no waste.
Many US Commercial cannabis facilities have been switching over to LED Grow Lights in order to produce a better smelling, better tasting, more potent product that sets them apart from the competition. Home growers looking to produce the best possible buds for themselves also benefit from grow lights that produce less heat and consume far less energy as the HPS counterparts.
Powered by nearly 200 K5 XL1000 KIND LED Grow Lights, The Herbal Garden in Pueblo, CO has revolutionized its facility, which is now running quieter, cooler and more efficiently. “We now run 100 percent Kind LEDs, so we are contributing to the solution, not the problem,” said Dave Ashby, The Herbal Garden’s Master Grower. “We are already seeing the benefits of using Kind LEDs. If you want to save yourself money, get a few Kind LEDs, they will offset your costs tremendously and give you amazing results.”

TV-Tube Technology Builds an Efficient Light Bulb
Power-saving light-emitting diode (LED) lamps are fast reshaping illumination’s cost and energy landscape, with long service lifetimes and high output in lumens per watt (lm/W). But LEDs don’t have everything. For example, operating these devices in high-temperature environments can shorten their useful lives by up to a factor of three. And many inorganic-LED bulbs include a variety of so-called critical raw materials, such as gallium, indium and rare-earth elements, that could face supply bottlenecks in the future. Engineering researchers in Russia have now demonstrated a different lighting architecture that they believe gets around some of these problems—an architecture that rests on the same vintage technology that drove old cathode-ray-tube TV screens.
Alloy LED Expands Product Lines with Innovative Products Catering to Custom LED Lighting Market

Miami-Dade Commissioners Say New LED Street Lights Could Lead to More Crime
A recent pool party in southwest Miami-Dade County was cut short by the sound of gunshots, as attendees trampled over each other in a rush to find cover. Miraculously, no one was hit. One county official has blamed the shooting, which remains under investigation, on an unlikely source: LED light bulbs. Miami-Dade Commissioner Dennis Moss lives a block from the house where the party took place and says he heard the gunfire that night. A few days after the shooting, during a county commission meeting, Moss argued that the gunmen were only able to sneak up on the home because of insufficient lighting on the street.
Ramen Lamp Has Us Feeling Hungry
Ramen comes in many forms, and whether you’re eating the 10 cent instant packets during the school year, or dining out at a fancy noodle bar, it’s a tasty meal either way. Ramenkingandi has long been in love with the classic Japanese fare, and decided to create a homage to the dish – in lamp form. The lamp build begins, somewhat unsurprisingly, with a lamp – but not how you’d think. A Walmart floor lamp is harvested for its lampshade, which approximates the dimensions of a typical ramen bowl. It’s then fitted with warm yellow LEDs to give it a pleasing glow.

Sensor-packin' bike wheel LEDs detect speed and light
Cyclists can already choose between plenty of cheap spoke-mounted LEDs that turn their bike wheels into highly-visible "rings of light" while they're turning. California-based startup MonkeyLectric has given the tech a new slant, though, with wheel lights that power up automatically – and only when needed. The result of a successful Kickstarter campaign, the new A15 Automatic Monkey Light consists of an LED module that is zip-tied to the spokes, along with a cylindrical battery unit that's likewise zip-tied to the wheel hub. An electrical cable, which is wound around one spoke, connects the two.
F&V Evertrue Z1200VC LED Light
If you’re in need of a high-quality LED, the Z1200VC is worth a look. It can deliver a color temperature range from 2800-6500K in White Light mode or a wider 2400-9900K in an extended Kelvin Mode. It features a TLCI (Television Lighting Consistency Index) of up to 99 and is dimmable from 0-100 percent. The light is calibrated on the factory end to be consistent from fixture to fixture, but is also designed to be recalibrated by end users if they spot a color shift. Thanks to its tint controls, you can adjust green and magenta tints so you can color match the light to other fixtures.

A Smart Buyer’s Guide to Light Bulbs
If Thomas Edison were to walk down the light-bulb aisle of a modern home-improvement store, he’d be shocked to see what’s become of his brainchild. Long gone are the days of simply choosing a light bulb based on its wattage. Today, light bulbs are available in a dizzying array of types, sizes, and shapes. Pity the poor shopper who enters the light-bulb aisle ignorant of the evolutionary changes to Ole’ Tom’s electric arc lamp, as it was originally called. Here are the five light bulbs you’re likely to encounter, and how to pick the best bulb for you.
BTU replacing all streetlights in city with LEDs
City streets in Bryan are getting new lights to brighten the night. Contractors are replacing all 6,300 streetlights in the city with more energy efficient LED bulbs. "When I came up and saw it so bright, the first thing that came to mind is like, 'Oh man, it's going to shine through my windows. It's going to be a little awkward.' But I went in my house and it wasn't really shining through my windows as much as I saw it in the front yard," said Mark Dearth.

Instead of settling for the lights that come with your house, change them for a better lighting experience
Our first — perhaps only — desire for lighting is that it improves our visibility in darkness. This is an important priority. But humans are surprisingly adaptive: In a pitch-black room, the light of a single candle will illuminate the space for us. Our eyes adapt from darkness to something-better-than-darkness quite quickly, even if it is far from the ideal degree of visibility. This is why we often settle for the lighting that comes with a house and, as long as there are lights in each room, we accept this lighting as “good enough.” Designing the lighting of your home builds — and can even determine — the environment for and usage of each space for a truly “illuminating” experience.
Light Emitting Diode (LED) Light Equipment in Global Optogenetics Market is Expected to Observe Fast Growth
LEDs are found to surpass the lasers in every aspect. The LEDs are found to be cheaper, smaller, more reliable, and easier to control. They are being incorporated into implants, allowing the untethered light delivery. The major drawback, and the reason they have not been as widely adopted by the optogenetics community is their difficulty toward coupling the light into a fiber optic cable with high efficiency.
Although individual LEDs can emit as much as five watts of light, the light is emitted in all directions, rather than in a coherent beam. These are one of the major factors that are restricting growth. However, a recent class of fiber-coupled LEDs offers much higher intensities of fiber-coupled light. Hence, there are many advances in both LED technologies and their applications. Effective LED therapies are used in treating cutaneous and neurological diseases. The researchers in LEDs, imaging, light therapy, and optogenetics have understood the basic principles, and hence, they are stimulating the application of LEDs in health care.
North America is expected to be the leading market for the use of the optogenetic device, primarily in academic and research labs. There is an increase in the number of neuronal diseases, such as epilepsy in the United States with at least 2.9 million adults and children being affected and also a steady increase in the number of neuropsychiatric disorders, which is expected to drive the growth of the optogenetic market. The most common optogenetics application today is with live animals and is rapidly being used in various academic and research labs across the country, which helps in driving the market globally.
