This LED Light Blub Saved My Indoor Plants From Dying a Slow Death in Winter

Most plants grow very slowly, or not at all, in the winter months when the sun is low in the sky—house plants are no exception. Even if it’s warm inside, plants can sense this external change. Some houseplants plants will drop leaves, turn brown, or even appear to die completely. Last year I finally had enough and went to the hardware store in search of a grow light to trick my plants, and maybe myself, into thinking it was summer. I chose the Fiet LED Grow Bulb. It’s energy-efficient (9 watts) and as advertised, never got hot (only slightly warm). This also meant I was able to maintain relatively stable humidity from day to night because hot lights will dry out the air.

Lux Lighting Opens Outpost in Industry City

The Los Angeles-based Lux Lighting is moving into Industry City, joining a roster of media and production companies in the Sunset Park campus, Commercial Observer has learned. The lighting company signed a 2,059-square-foot lease at 88 35th Street, according to information from Industry City. Its new space will serve as its administrative offices, as well as a warehouse for equipment and rentals, and a service center for customers.

Introducing the world's first Bluetooth-enabled wax candle

There are few things more calming than coming home from a long day at the office and lighting a wax candle. My mind was blown when I learned that Candle Touch has developed the world's very first real-fire wax candle that can be lit using an app. Each candle has a self-ignition mechanism, which works in combination with Bluetooth technology that reaches as far as 60 feet. All you have to do is tap your finger, and you can light up to 10 candles at a time. Now that's what I call efficient.

A Brighter Future With New LED Light Bulbs

In a time of environmental consciousness and sustainability, SUNY New Paltz has started the process of replacing all light bulbs on campus with LED (light-emitting diode) light bulbs. Before switching to LED, the campus was using compact fluorescent light bulbs (CFLs) and incandescent light bulbs, which have been proven to be less efficient and worse for the environment than LED lights. According to Project Drawdown, “lighting accounts for 15% of global electricity use,” so a switch to more efficient light bulbs will make a substantial difference. Project Drawdown studies climate change solutions and works with policy makers to impliment them.

Does lighting affect fps on webcams?

Lighting affects webcam videography in a similar way that lighting affects photography. Things like exposure time and shutter speed need to be taken into account, but unlike photography, or even traditional videography, we don't have the same manual control over those settings like we do with a professional camera. That's what makes lighting so important when filming something with our webcams, even if we prefer to keep our rooms dimly lit from the glow of our PC (assuming you are all about that RGB.) Basic lighting from a room lamp or kitchen may be sufficient enough for a video conference or a virtual tabletop RPG gathering, but if we want to add our faces to our Skyrim or Apex Legends streams, something like the Razer Kiyo or Elgato's Key Light would help eliminate any framerate drop due to bad lighting.

We Ruined Status LEDs; Here’s Why That Needs To Change

The 1990s brought us much good: Nirvana, Linux, and of course the blue LED. Much like “Teen Spirit”, the latter quickly fell into overuse: the technology rapidly became the sigil of all that was new and great, much to the ocular pain of the buying public. This decision ranks up there for stupidity with other such questionable choices as hiring a rental car at the airport, or invading Russia in the winter. A status LED, most would agree, is there to indicate status. It need only deliver enough light to be seen when observed by a querying eye. What it need not do is glow with the intensity of a dying star, or illuminate an entire room for that matter. But, in the desperate attempts of product designers to appear on the cutting edge, the new, brighter LED triumphed over all in these applications.

Light + Building postponed; Signify leads cancellations due to coronavirus

Mondays tend to bring the most news no matter the business sector of interest, but this Monday, Feb. 24, was still surprising given that Signify (formerly Philips Lighting) announced it would not attend the Light + Building (L+B) event, and a short time later L+B organizers announced a plan to postpone the trade fair until a still-to-be-specified date in September. The coronavirus is the culprit, and specifically the realization over the weekend that a cluster of cases had been documented in Northern Italy. The move to postpone L+B is both precautionary and the result of incredible logistics obstacles that the organizers would have faced to go forward with the event originally planned for Mar. 8–13 in Frankfurt, Germany, and easily the largest event globally for the LED and solid-state lighting (SSL) sectors.

How Many LEDs Can You Drive?

Driving more than a handful of LEDs from a microcontroller is often a feat that takes tedious wiring, tricking the processor, or a lot of extra external hardware. Charlieplexing is perhaps the most notorious of these methods, and checks two of those three boxes. This library for the Teensy 4.0 checks all three, but it can also drive a truly staggering 32,000 LEDs at one time.

LED lighting market in North America poised to grow by USD 6.73 billion

The LED lighting market in North America is poised to grow by USD 6.73 billion during 2018-2022, progressing at a CAGR of almost 12% during the forecast period.

The market is driven by the declining manufacturing costs of LEDs. In addition, the rising demand for intelligent lighting systems is anticipated to boost the growth of the LED lighting market.

Since 2012, the manufacturing cost of LEDs has declined steadily and is expected to reduce further during the forecast period. This is due to the decrease in the average selling prices of chips and components used in the manufacturing of LED devices. The decline in the cost of LEDs has reduced the initial investment cost of LED lighting lamps and fixtures. These factors are driving the growth of the LED lighting market in North America.

LED lights: How bright should they be?

City council recently approved an agreement with Toledo Edison to replace all 28,000 streetlights in the city with LED fixtures by the end of 2021. The project will cost the city about $5.8 million, no matter how bright the bulbs, and officials estimate it will translate to about $580,000 in annual energy savings. The city is now debating between installing fixtures that have a brightness of 4,000 Kelvin or 3,000 Kelvin. The higher the number, the brighter and whiter the light is, officials said.

Chicago reaches milestone for installation of LED streetlights

Outdoor Lighting Standards Changed To Reduce Glare

Fairfax County is updating its outdoor lighting standards to reduce glare and excessive illumination and match the expanded use of LED lights, which can improve the quality of life for county residents. On Feb. 11, the Board of Supervisors approved an amendment to the outdoor lighting regulations of the Zoning Ordinance to match lighting industry standards that lean toward more energy efficiency and warmer color temperatures.

Have LED Bulbs Reached Their Final (and Cheapest) Form?

Electronupdate has done a lot of LED light bulb teardowns over the years, witnessing a drive towards ever-cheaper and ever-simpler implementations, and suspects that LED light bulb design has finally reached its ultimate goal. This teardown of a recent dollar store example shows that cost-cutting has managed to shave even more off what was already looking like a market saturated with bottom-dollar design. The electrical components inside this glowing model of cost-cutting consists of one PCB (previously-seen dollar store LED bulb examples had two), eleven LEDs, one bridge rectifier, two resistors, and a controller IC. A wirewound resistor apparently also serves as a fuse, just in case.

Moriah plans transition to LEDs

Politicians mess with street lights at their peril. Early in his career, Moriah Supervisor Tom Scozzafava said there was a plan to remove one such light near a farmhouse out in the boonies. The farmer called Scozzafava to his house and explained that he was too far out to get any benefit from any other public service such as sewer and water, and the street light was the only indication that he was getting something for his tax money. The street light stayed. But now the town board will consider a plan that they hope the public will be amenable to: Replacing the town’s nearly 700 low-pressure sodium vapor street lights with cost-saving LEDs.

Apocalyptic subterranean future has these LED skylightsS

Mitsubishi has released a new LED light panel that mimics the three-dimensional appearance and light output of a skylight. The idea was first announced in 2018. But this February, more specifics came to light (as spotted by Gizmodo) with a name, sale date, and a price tag. The Misola system will come out in October 2020, and will go for between $6,200 and $6,800, depending on whether it's programmed manually or automatically.

Why Aren’t We Hacking On The LED Printer?

Strings of LEDs are a staple of the type of project we see here at Hackaday, with addressable devices such as the WS2812 in particular having changed beyond recognition. They’ve appeared in all kinds of projects, but are perhaps most memorable when used in imaging projects such as screen-like arrays or persistence-of-vision systems. There’s another addressable LED product that we haven’t seen here, which is quite a surprise considering that it can be found with relative ease in junk piles and has been on the market for decades. We’re talking about the LED printer, and the addressable LED product in question is a very high density array of LEDs the width of a page, designed to place an image of the page to be printed on the toner transfer drum.

Low-profile, high-tech art graces North Liberty bridge

Subtle public art glows in North Liberty (Iowa City) which you may not notice on a casual drive through town on Highway 965. It’s the colored-light side panels on the recently-refurbished bridge over the pedestrian underpass connecting foot traffic between east and west sections of Cherry Street. A dozen aluminum panels on either side of the highway, now called Ranshaw Way in the city limits, feature a swooping design of cut-out broken patterns forming straight and curved lines which periodically change color.

Here’s how to install lighting dimmers in your home

The flick of a switch or a slow transition, how do you like your light? Dimmers vs. traditional light switches create ambiance and can reduce the number of times you get up from the sofa to turn the lights on and off. Noel Pena, electrician, Fox Valley Electric, a Rosie-Certified partner explains the real difference between traditional and dimmer switches. “A traditional light switch simply supplies or cuts the power to the lamp or bulb. A dimmer switch used to work by means of a variable resistor, the more resistance, less energy to the bulb and more heat at the dimmer switch therefore dimmer light,” Pena said.

This Renewable Energy Device Powers 100 LEDs with a Single Drop of Water

What if your umbrella could charge your phone? That speculative tech just got a bit closer to reality now that scientists have designed a small, highly efficient electricity generator that can create enough charge with a single droplet of tap, rain, or seawater to power 100 LED light bulbs. The researchers hope that, alongside solar and wind power, the approach can help tackle the world’s energy crisis. Obviously, generating electricity with water is nothing new. But the study, published on Wednesday in the journal Nature, looked at how a unique connection between the water droplets and the generator interface increased the generator’s overall power.

Global High Power LED Market Expected to Witness a Growth with a CAGR of 5.3%

The high-power light-emitting diode market is projected to generate $17,581.5 million in 2024, witnessing a 5.3% CAGR during the forecast period (2019-2024).

The key factors driving the market are the growing government support for the adoption of LED lights and increasing adoption of energy-efficient lighting solutions.

Among these, the automotive application is expected to grow at a CAGR of 5.4% during the forecast period. This is ascribed to the growing requirement for high-power LED lights in automotive interior and exterior applications, including position lights, ambient lighting, fog lights, headlights, and dashboard lights.

Geographically, Asia-Pacific (APAC) is projected to hold a considerable share of the high-power LED market during the forecast period. The primary reason for this is the rising adoption of these LED lights in general lighting applications, majorly in India and China.
Furthermore, various smart city projects are in their developmental phase in these countries, which are predicted to create a huge demand for high-power LED lights. For example, in 2012, China introduced a national smart city development project, which will utilize modern technology for building smart cities.

The governments have started focusing on saving energy, which is why the requirement for energy-efficient lighting solutions is increasing. This is further leading to the growth of the high-power LED market, since high-power LEDs are able to work efficiently for long periods of time and at low maintenance cost. Because of these advantages, the local authorities of several countries, including Australia, the U.S., China, and India, have introduced projects in order to replace their traditional lighting lamps, which are utilized in outdoor lighting, with LEDs.
