Greenhouse LED Lamp Grow Plants Indoor 24W Light Bulb Protection Launched

A new LED bulb aiding the growth of plants has been launched by Vetomix, an online lighting specialist. These new bulbs help customers to grow and maintain plants in areas of low natural sunlight and in the depths of winter. Vemotix, an online lighting retailer, has released a new lightbulb to aid plant growth. This new LED grow bulb is suitable for helping plants grow in areas where not enough natural light reaches, and is ideal for customers looking to create and maintain greenhouses indoors, where the plants are protected from harsh weather.

The best RGB LED Lighting Kit

If there’s one single feature PC hardware companies have beaten to a bloody pulp by now, it’s RGB lighting. Some purists argue that it’s an unnecessary gimmick, but others can’t help but be drawn to the appeal of having a 24/7 party on their desktop. Lucky for them, there’s also plenty of LED lighting options to bring the party to the PC too. Lighting up the interior of a PC is nothing new. Cold cathode light tubes, basic LED strips and LED fans have been used to light up builds for well over a decade now. But with more and more users showing off the inside of their clean builds, it was only a matter of time before RGB hit the interior lighting space.

Taiwan firms developing IR LED devices for biometric applications

Chip makers and LED packaging service providers in Taiwan have developed IR LED chips or devices for biometric applications, mainly iris and facial recognition, and are in the process of certification by potential clients, according to a report by Digitimes. Industry sources report that shipments are expected to start in 2017. The report cites unnamed sources that say Epistar has IR LED chips taking up over 10% of all AlGaInP chip output at present, and the proportion is expected to rise to 30% in 2018.

Utility Company Replacing Street Lights With LEDs To Reduce Cost

A northern Indiana utility plans to convert existing street lights to light-emitting diode technology to reduce energy costs. NIPSCO announced Wednesday it will make the change at no additional cost to participating communities. NIPSCO says the LED street lights are expected to cut energy costs by 22 percent and will have a 10-year warranty and a 20-year expected life. The utility says traditional lights require service every two to three years on average.

Several Cities Convert To LED Streetlights In Conservation Efforts

Cities around the country are turning to light-emitting diodes, or LEDs, for their street lights. These bulbs use less energy, last longer and are smaller than traditional lights and they save money. But there's a problem with some LEDs, Grace Hood of Colorado Public Radio reports. The small southwestern Colorado city of Ouray is known for hiking and ice climbing. In 2009, Ouray's city administrator Patrick Rondinelli and others jumped at the chance to install LED streetlights. It became the first in the state to make the move.

Nichia’s Developments for Micro-LED and Other Lighting Technologies in 2017

The slowdown in LED backlight market including smartphone displays continued to trend on into 2016 that even top player in the industry Nichia is looking beyond this particular market sector in its 2017 roadmap. Offset by oversupply and cutthroat price wars in 2015, LED backlight market competition remains intense and the market decreased steadily, by the start of 2016 growing number of LED manufacturers started to look into other niche lighting market applications, such as automotive lighting, UV LED, IR LED, and others.

People on Instagram Are Obsessed With Drinking Out of Light Bulbs

Last April, the Hyundai Department Store in Seoul, Korea, began using lightbulbs instead of glasses to serve their bubble tea. No, really. The store uses an actual lightbulb to serve the beverage and, as if that's not cool enough, they also attach a light-up clicker to the straw. It's lit! Literally! About a month after the drink became popular in Korea, a café in Taiwan went viral for photos of two servers holding lightbulbs filled with bubble tea. Unsurprisingly, an Instagram trend was born and now it's making it's way through the United States from California to New York.

How Light Bulbs Watch You Buy Groceries

In an enormous grocery store in northern France, the lights above the aisles aren’t all they seem to be. They look ordinary—more than a mile and a half of fixtures exuding bright light, folded into a grid overhead—but they’re actually flickering faster than the human eye can see. The unique patterns each individual section of lighting emits are a 21st-century twist on Morse code, meant not for people, but for the cameras on their phones.

Selectmen Beacon Falls approve switch to LEDs

Beacon Falls is set to become more energy efficient. The Board of Selectmen voted to allow Eversource Energy to replace all the streetlights in town with energy efficient light-emitting diodes, or LED bulbs. First Selectman Christopher Bielik said the company offered to do the upgrades throughout the town for free.

Cree goes after flashlight maker over counterfeit LEDs

Cree is calling out U.S.-based E. Mishan & Sons, Inc. (Emson), which it claims has infringed its patented LED technology used in Emson flashlights, including the Bell & Howell Tac Light. It appears that Cree notified Emson regarding their claims this past August, but the products remained on the market, causing Cree to claim intentional and wilful infringement.

Quantum dot LEDs that can produce entangled photons

Conventional digital computing uses 'on-off' switches, but quantum computing looks to harness quantum state of matters—such as entangled photons of light or multiple states of atoms—to encode information. In theory, this can lead to much faster and more powerful computer processing, but the technology to underpin quantum computing is currently difficult to develop at scale. Researchers at Tyndall have taken a step forward by making quantum dot light-emitting diodes (LEDs) that can produce entangled photons (whose actions are linked), theoretically enabling their use to encode information in quantum computing.

East Lyme to begin retrofitting streetlight with LEDs

The town is moving forward with retrofitting all of its streetlights with new LED fixtures. Red Thread, the electrical contractor, said it will have two crews doing about 30 fixtures a day. There are about 1,300 cobra-head fixtures through town, so the work will take about 5 to 6 weeks for this first phase. The contractor plans on moving through town from north to south. The second phase will be changing out the fixtures on stand-alone poles, which should start in January.

LEDs: Saving The World And Also Attracting Fewer Insects

Light emitting diodes (LEDs) are slashing carbon dioxide emissions and bringing light to millions who previously could not afford anything better than kerosene lamps. But one feature of these works of genius has been overlooked, until now – they attract fewer insects to annoy you on an otherwise pleasant evening outside.

2000 LEDs on Fire

What’s 18 feet tall, 12 feet wide, has 2,000 LEDs and turbine-driven blast furnaces? Believe it or not, it is a piece of kinetic sculpture created by Therm (a collective, not a person) for Burning Man 2016. The project is about 60% salvage, has a Raspberry Pi 3 helping its three human operators, and took a team of 30 about 9 months to complete. The Raspberry Pi drives LED using fadecandy. You can see a video of the sculpture (three giant moths, to be exact) and a video about fadecandy, below. (We’ve covered a subtler fadecandy project before if you want to see a different take on it.)

Meriden replacing thousands of streetlight bulbs with LEDs

Workers are replacing the sodium bulbs in over 4,200 streetlights with LED bulbs that are expected to save the city $9 million over the next two decades. The $2.5 million project consists of buying the LED bulbs from Eversource Energy and replacing the lights on all city-owned utility poles, said Stephen Montemurro, the city information technology director.

New LEDs may offer better way to clean water in remote areas

Engineers at The Ohio State University are developing the foil based LEDs for portable ultraviolet (UV) lights that soldiers and others can use to purify drinking water and sterilize medical equipment. In the journal Applied Physics Letters, the researchers describe how they designed the LEDs to shine in the high-energy "deep" end of the UV spectrum. The university will license the technology to industry for further development. Deep UV light is already used by the military, humanitarian organizations and industry for applications ranging from detection of biological agents to curing plastics, explained Roberto Myers, associate professor of materials science and engineering at Ohio State.

This $5 Solar Lamp Replaces The Fumes And Fire Risk Of Kerosene Lanterns

The SolarAid lamp is designed for "off-grid families and school children," and is both cheap to buy and cheap to run. It's tough, and unlike kerosene you don't need to buy fuel for it. It won't choke children while they do their homework, and it is twice as bright as a kerosene lamp.

$35 Billion LEDs and the Worldwide Market for Lighting Fixtures 2016-2020

The worldwide consumption of LED lighting fixtures was worth USD 35 billion in 2015, equal to around 40% of the worldwide consumption of lighting fixtures, and according to estimates, it will reach USD 70 billion in 2020. In the coming years it is expected that commercial and outdoor lighting market segments will be the main growth drivers for LED lighting fixtures. One hundred among the top manufacturers of lighting fixtures worldwide hold around 55% of the total LED lighting market, registering an average 24% growth. Their LED share on total lighting sales was about 13% on average in the year 2009 and it grew to 57% in 2015.

LED based lighting fixtures weight today around 14% on the overall consumer/residential lighting fixtures segment, over 50% on the commercial and outdoor segments, over 40% in the industrial lighting field. LED lighting fixtures weighted just 5%-6% on the overall lighting fixtures market in 2008-2009. In the year 2015 they weight around 40% on the overall lighting fixtures market, and their share is forecasted to grow up to 65%-66% in the year 2020

First self-cooling eco-home unveiled in Dubai

A full-sized home that cools itself in the UAE’s scorching summer heat was unveiled in Dubai on Friday. At first, the two-storey, four-bedroom house, which stands in the headquarters of the Mohammad Bin Rashed Space Centre, seems like a fairly normal family home. But closer inspection reveals the 6,000 square foot concept’s green credentials, which space centre officials claim make it the region’s first sustainable home. All the lights are motion-activated LEDs, while blinds covering the home’s triple-glazed windows open and close automatically.

LED lights make gardening possible year-round

There's no reason to stop growing vegetables just because cold weather has arrived. Sun-loving edibles can be cultivated indoors in containers enriched by supplemental LED lights. But choose the right plant combinations for this four-season gardening. Some plants are more demanding than others. "The amount of money and work it takes depends upon your expectations," said Tuan Bettes, a horticulture agent with Utah State University Extension. "You won't achieve (indoors) what you would in sunlight."

Top 10 Vendors in the LED Lighting Market for Horticulture Application from 2016 to 2020

Technavio has announced the top 10 leading vendors in their recent global LED lighting market for horticulture application report. The report presents the major vendors that manufacture LED lighting products for horticulture applications in the Americas, APAC, and EMEA.

Several characteristics of LEDs such as low energy consumption and high life-expectancy have garnered attention from lighting manufacturers across the globe. As a result, manufacturers are investing heavily in developing LED lighting products for applications in the architectural, industrial, outdoor, office, retail, and residential sectors. Such developments are improving LED technology, resulting in better performance of LED lighting products.

This is driving the development of LEDs in horticulture applications. The manufacturers in lighting industry are focusing on the development of LED products, as they have several advantages over traditional lighting sources.

The competitive scenario of the global LED lighting market for horticulture applications is entirely different from the global LED market in other applications segments. In other applications, big players such as Cree, Nichia, Samsung LED, Philips lighting, OSRAM Opto Semiconductors, and Seoul Semiconductor dominate the market, while in the global LED lighting market for horticulture applications there are no dominant players. The market is flooded with several small players that have captured significant market share in their respective regions.

Trace metal recombination centers kill LED efficiency

Using cutting-edge first-principles calculations, researchers at the University of California, Santa Barbara (UCSB) have demonstrated the mechanism by which transition metal impurities - iron in particular - can act as nonradiative recombination centers in nitride semiconductors. The work highlights that such impurities can have a detrimental impact on the efficiency of light-emitting diodes (LEDs) based on gallium nitride or indium gallium nitride. For LEDs, high-purity material is essential to lighting technology, such as residential and commercial solid-state lighting, adaptive lighting for automobiles, and displays for mobile devices. Imperfections at the atomic scale can limit the performance of LEDs through a process known as Shockley-Read-Hall recombination.

Digital LED Suits Future Automotive Applications

Inova Semiconductors has unveiled a new digital light-emitting diode (LED) concept for automotive applications with the first LED product to be available from Dominant Opto Technologies in the first quarter of 2017. This will be the first product developed under the umbrella of ISELED, an open alliance formed to provide a full ecosystem for the new digital LED right from its very inception. The mission of the ISELED Alliance is to create LED-related products and solutions for the automotive market. These solutions are to be based on an entirely new in-car LED lighting concept that drives down costs, simplifies control, and expands the functionality of LED lighting and display solutions

LEDs come in rainbow colours

Previously the only way to achieve non-standard LED colours was to use RGB colour mixing, which involves three times as many chips, complex wiring and requires drive circuitry to control the relative channel levels. OMC’s Active Reflector Technology uses photon wavelength up-conversion to produce colours and pastel shades.

Opel Introduces New IntelliLux LED Headlights on the New Insignia Grand Sport

One of the aspects where the mainstream cars and the lower segments are a bit lacking is their lighting systems. You might think LEDs have become the norm, but try buying a Volkswagen Golf and you'll be surprised to find out that the LED daytime running lights don't come standard. In fact, you won't get them even if you order the optional xenon lamps, but only on the top-spec lighting package (that still doesn't use LEDs for either low or high beams). And it's even worse in the premium segment.

Consider all of your options when choosing a type of greenhouse lighting

There are numerous lamp types that are commercially available for use in controlled environment horticulture. These lamp types can be categorized into two classifications: photoperiodic and photosynthetic lighting. Photoperiodic lighting is used in greenhouses to regulate the duration of the light, or photoperiod. Photoperiodic lighting is delivered at low intensities and regulates flowering and dormancy of plants. In contrast, photosynthetic lighting is delivered at high intensities and affects plant quality characteristics, such as root and shoot growth and branching.

Philips’ Trailer Dome Lamps are Brighter

Philips Industries is offering a new brighter LED Dome Lamp for commercial trailers that is available with or without motion sensors. The Philips Permalite XB LED high-efficiency trailer dome lamps are designed to be brighter than competitive lights, with 20 LEDs and 2,200 lumens. The lamps are multi-volt, allowing them to run on a 12 or 24-volt system and offer consistent lamp output throughout the voltage range. With a slim, lightweight design and universal mounting holes, the Permalite XB LED high-efficiency dome lamps are made to fit most applications.

Science can inform better lighting decisions

Dunedin has an opportunity to become the first Night Sky City in the southern hemisphere,  but the success of this visionary endeavour hinges upon one important factor: night sky-friendly streetlights. Unfortunately, there’s confusion about what’s involved. Lighting is a  complex issue.  White LEDs are  being heavily promoted for their energy efficiency, they have other costs, which outweigh energy, maintenance and operational savings. The implications are serious  because LED technology is rapidly being installed around the world.

LED streetlights coming to Columbus

Columbus public utilities officials are planning a massive expansion of its streetlight system, as first reported by Columbus Business First, that would replace all of its 53,000 streetlights with LED lamps. Just 0.38 percent, or 200, of the lights are outfitted with longer-lasting, energy-efficient LEDs. Additionally, one-third of the city remains unlit, so the city wants to expand its LED lighting campaign to roughly 680 miles of roadways. But bringing more light to city streets isn't universally beloved. There's the classic worry about adding more light pollution and preventing even more of the night sky's charms from being seen.

Streetlight conversions to LEDs continue throughout the country

Cities across the country have found monetary, energy and sustainability savings in converting existing streetlights to LED bulbs. The trend in streetlight conversions continues across the country. Greer, S.C., recently replaced 128 high-pressure sodium (HPS) streetlights with LED lights in Greer Station, its historic downtown district, the Spartanburg Herald-Journal reports. The upgrade is expected to save about $5,000 per year in operations costs. “The difference is very noticeable," Greer City Administrator Ed Driggers said in a statement. “City residents and visitors will be excited to know that this is simply the first step of beautification and infrastructure improvements in Greer Station in keeping with the community master plan.” 

Switching to LEDs Without Leaving the Past Behind

The change to LEDs is perhaps the lowest hanging fruit in the battle to become more energy efficient and environmentally sound. The only step that seems close is solar energy, but that transition demands non-trivial infrastructure and procedural changes. The move to LEDs is far simpler. After all, it generally only requires a new fixture. Not always, however. In some cases, building management has great interest in saving the original fixture while changing from legacy lighting to LEDs. In some cases employees are comfortable with the old style and find it more conducive to their business, which makes them more productive. It also may be required in buildings that are deemed by official proclamation to be historic sites.

BlitzWolf LED Desk Lamp

The BlitzWolf LED desk lamp is one of a new generation of ergonomic, flexible and adjustable desk lamps. This is a contemporary style light, and it offers considerable flexibility. The light is mounted to its base (metal for stability) with a 180-degree turntable. Above the controls is a 40-degree adjustable joint and the head itself features a 140-degree joint. In addition, the head can be rotated up to 90-degrees in either direction.

City of Henderson Rolls out Upgrade of 6,200 Light Fixtures to LEDs

The City of Henderson in partnership with McKinstry, a design-build company specializing in energy-based retrofits, will replace more than 6,200 light fixtures across the city with energy-saving LEDs that will pay for themselves in just over seven years. Currently, the light fixtures across the city’s trails, parks and buildings offer variable quality lighting and the majority are aging past their useful life. These lights use a significant amount of energy and are challenging to maintain.

Preferred Freezer uses LED to create cool temperatures without the extra cost

Preferred Freezer takes great pride in its temperature controlled warehouses. From modest beginnings in New Jersey, the company has grown to become one of the largest public refrigerated warehousing companies with more than 1,600 employees. Preferred Freezer strives to be the best in its industry, which means keeping constant watch over the issues most relevant to its operation: maintaining quality product for their customers, speed and accuracy in picking (retrieving products from the warehouse), safety and cleanliness and a constant drive to improve the bottom line. These efforts led the company to LEDs.

OLED vs. LED: Which is the better TV technology?

OLED technology isn’t exactly new to the consumer electronics space anymore. Mobile phones have been using OLED screens in some form or another since 2001. But now that OLED televisions from LG are coming down in cost (with the promise of competition coming soon), people’s interest in OLED is beginning to tick up, and they have questions. What makes an OLED TV better than an LED or LCD TV? How is OLED superior? Are there any disadvantages to OLED? We’ve got answers.

Marset's cordless Ginger lamp is designed to be carried from room to room

Barcelona brand Marset has released a portable lamp with a rechargeable battery that allows it to be detached and carried around the house. The Ginger light's battery allows it to function cordlessly, letting users take the lamp from room to room, and plug it back in to recharge.

LEDs and Lasers Battle for Dominance in Brain Research

Lighting up the brain to better understand, treat or even cure brain disorders has become an established field known as optogenetics. First introduced in 2005 by professor Karl Deisseroth as he worked in a small laboratory at Stanford University, it has since been named Method of the Year by the journal Nature and is today one of the most promising tools making contributions to the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative — part of a new federal focus aimed at producing a dynamic picture of the brain.

Occupancy Sensors and LEDs Evolve in Unison

Light sensors have been on the scene, at least in rudimentary form, for years. The idea is a simple one: If lights can be more tightly controlled, their cost to operate will go down. The most obvious example is restroom lights that turn themselves on and off as people enter and leave. The trend of the past few years is that modern telecommunications and IT technology is taking these technologies to new levels in a couple of ways. The most obvious is that they lower optional expense (opex). On a more subtle level, they collect data on how lighting

If you don't own this Harambe lamp, it's time to rethink your life

In the northern islands just above Scotland proper sits Orkney, an archipelago with just over 20,000 people. Its library has gained great internet fame thanks to an online presence as quirky as it is informative. Recently, its verified Twitter account sent out a beacon of distress about a book of lampshades. Turns out the light-diffusing tome had been lost (again). Wherever could it be?

Blooming Flower Lamp Will Test Your 3D Printer

LEDs Light Up Indoor Farming and Marijuana Cultivation

The overall LED grow-light module market is expected to grow from $395 million in 2013 to $3.6 billion by 2020, according to WinterGreen Research. That ridiculous rate of growth will in large part be driven by medical marijuana legislation and indoor grow rooms. A 2012 study from Berkeley Lab found that indoor marijuana production could account for as much as 1 percent of U.S. electricity use, about half the amount consumed by data centers. As GTM's Katie Tweed reported, within the city of Denver, marijuana grow operations are using more than 2 percent of electricity. By 2035, the state of Washington expects marijuana-related energy use to exceed the energy draw of electric vehicles.

Long live the Livermore bulb

Yes, incandescent lamps are still with us. A lamp's service life can be extremely brief or it can extend for many hours, days, months, years, or even decades. Theatrical lamps for example are run at great stress to get as much light out of them as possible and as a result, they may only last for perhaps a few hours. The Centennial Light has been operating almost without interruption since 1901.

DIY Plant LED Light Prototype Lights Up The Winter

With winter on the way, our thoughts turn to indoor hacks. And what could be better in the cold winter than fresh veggies? This can be done by replacing the sun with an LED light, and Margaret Johnson, aka Bitknitting has been working on building her own LED plant light. She’s using a combination of red and blue LEDs that produce the ratio of light frequencies that plants thrive on, and has been experimenting with how bright to make them and how long to run them. This combination of factors determines how much light the plants get every day, called the Daily Light Integral, or DLI, and has a huge effect on how well the plants grow.
