I’ve written before about the mounting scientific evidence of a dramatic global collapse in insect and bird populations due to white LED streetlights. I predict, over time, a return to amber streetlighting, but this time instead of HPS & LPS, it will be amber LED sources. This trend has already begun with several different manufacturers now offering amber streetlights. Another of my recent posts covered the recent DLC white paper about Non-White Light Sources For Nighttime Environments.

One of the pioneer manufacturers is Crossroads LED, whose innovative Astrophile Series street lights won the company the IDA’s 2021 Best Design And Technical Innovation Award. This award is given to individuals, organizations, or businesses that – through progressive design, construction, technological innovation, and entrepreneurship – support IDA and its mission to preserve night skies by promoting quality outdoor nighttime lighting.

The Astrophile Series is the first Phosphor Converted Amber (PCA) streetlight with a correlated color temperature range between 1650K and 2000K and a Narrow Band Amber (NBA) streetlight with a peak dominant wavelength of 592nm ±2.5nm. Most notably, the 1650K PCA and the 590nm NBA LEDs have zero emissions of short-wavelength blue light. Additionally, Crossroads LED incorporated an adjustable optical shield that reduces and eliminates both house and street-side light trespass, as well as a new aluminum housing designed exclusively to recess the LED lenses deep within the fixture, effectively reducing both nuisance and disability glare. Cities in New Mexico, Arizona, California, Missouri, and Washington state (USA) have all either committed or shown interest in the Crossroads LED “Astrophiles Series.”

‘Big Plumbing’ Muscling Into Lighting

For the past two decades, thought leaders in the lighting industry have been publicly lamenting that the lighting industry will be gobbled up by the electronics industry, Silicon Valley tech giants, and the big telecoms. 20 years into the LED era for general lighting, and this still has not come to pass.

For the past two decades, thought leaders in the lighting industry have been publicly lamenting that the lighting industry will be gobbled up by the electronics industry, Silicon Valley tech giants, and the big telecoms. 20 years into the LED era for general lighting, and this still has not come to pass.

However, there is another, less glamorous industry slowly increasing its acquisitions, footprint, and influence in the lighting industry, and it is hardly getting any attention. It’s Big Plumbing. Perhaps the most recent and largest move was Ferguson’s recent acquisition of Minka Group, a major decorative lighting manufacturer for the residential and resimercial markets. Ferguson is the largest wholesale distributor of residential and commercial plumbing supplies and pipe, valves and fittings in the U.S. The company also has 245 Ferguson Bath, Kitchen & Lighting Gallery locations in the United States that sell lighting and fan products. Ferguson is a $24 billion company that is listed on both the London Stock Exchange (LSE:FERG) and the New York Stock Exchange (NYSE: FERG).

The Minka Group acquisition was just the latest move by Ferguson into lighting. Back in January of this year, Ferguson quietly acquired RP Lighting + Fans, another decorative manufacturer of lighting and ceiling fans.

It’s not just Ferguson, either. Kohler Company introduced its Kohler Lighting line in 2020, in order to provide decorative luminaires that pair with its plumbing fixtures. Moen also offers decorative lighting. Keep your eye out for continued moves by Big Plumbing.

What If Lighting Designers Created Their Own Project Software?

At LightFair, last week, I had the pleasure of speaking with Mike Bishop, VP of Sales, at Sourcery, based in Toronto, Ontario, Canada. Sourcery is a lighting design project collaboration software platform created by lighting designers for lighting specifiers, reps, and manufacturers.

At LightFair, last week, I had the pleasure of speaking with Mike Bishop, VP of Sales, at Sourcery, based in Toronto, Ontario, Canada. Sourcery is a lighting design project collaboration software platform created by lighting designers for lighting specifiers, reps, and manufacturers. It is a social collaborative platform for design industry professionals to seamlessly collaborate with one another when specifying and procuring products in every phase of a project. It makes the process of selecting and procuring products for commercial construction easier and more efficient.

Sourcery was not created by software people, it was created by and for lighting specifiers:

  • To use modern cloud computing tools to create a single point of truth, for a project, with all information in one spot.
  • To be the birthplace of the digital twin.
  • To simplify product selection by maintaining libraries and custom collections of products to create curated categorized lists, assign to projects, and generate luminaire schedules in a few clicks.
  • To collaborate through a live luminaire schedule that improves the process of specifying lighting products and collaboration during design.
  • To enhance transparency through a project management companion, to make the procurement process transparent throughout all stages of design, budgeting, bidding and construction.
  • To provide a direct connection to products and sourcing new manufacturers.
  • To provide the project specifier full control over who has access to specific documents, schedules, libraries, pricing, and other important information.

IDA Releases 2022 State of the Science Report On Light Pollution

The International Dark-Sky Association (IDA) released the “Artificial Light at Night: State of the Science 2022” report, earlier this month. It is a high-level overview of the best scientific understanding of how artificial light at night affects the nighttime environment. It finds the world transformed by electric light in less than 150 years since its introduction.

The International Dark-Sky Association (IDA) released the “Artificial Light at Night: State of the Science 2022” report, earlier this month. It is a high-level overview of the best scientific understanding of how artificial light at night affects the nighttime environment. It finds the world transformed by electric light in less than 150 years since its introduction.

IDA’s goal in issuing the report is to empower dark-sky advocates and the public with reliable, factual, understandable information about light pollution. “State Of The Science 2022” condenses the current scientific consensus on how artificial light affects seven key topics:

  • the night sky;
  • wildlife and ecology;
  • human health;
  • public safety;
  • energy use and climate change;
  • social justice; and
  • a discussion of the emerging threat from light pollution caused by objects orbiting the Earth.

Where gaps exist in the science, the report highlights them as targets of future research. Read the full report, here.

NEMA Publishes Recommendations For Standby Power Measurements For LED Drivers

The National Electrical Manufacturers Association (NEMA) published a new white paper NEMA LS 20003-2021 Standby Power Measurements for LED Drivers—Recommended Allowances for Feature Sets Other Than Lighting, for LED driver manufacturers and testing laboratories.

The National Electrical Manufacturers Association (NEMA) published a new white paper NEMA LS 20003-2021 Standby Power Measurements for LED Drivers—Recommended Allowances for Feature Sets Other Than Lighting, for LED driver manufacturers and testing laboratories. Developed alongside ANSI C82.16, the two documents should be read in conjunction with each other. NEMA Lighting Controls Technical Committee Chair Stephen Irving says the publication “strikes the right balance between minimizing standby power usage and ensuring that smart-enabled LED driver features remain available to customers. It can be used by manufacturers during the design of new products and by other standards-setting bodies when considering limits for LED driver standby power usage.”

Twelve Interesting Products & Trends From LightFair 2022

David Shiller shares his top product and trends finds at LightFair 2022.

It was great to get back to LightFair International (LFI), last week. It was a significantly better show than last year’s (IMHO), but still roughly half of the exhibitors of a pre-pandemic LFI. Here is a fast recap of my favorite products and trends at LFI, last week:

  • Additional manufacturers showing and offering street and area lights with LED amber sources. These can be direct emission amber LEDs or phosphor-converted amber LEDs (1800K – 2200K). Most folks know about amber sources for “turtle-safe” lighting, in Florida and other Southeast municipalities. However, due to global collapses in both insect and bird populations attributed to white LED lighting, there are a growing list of municipalities requiring amber street and area lighting. I learned that Austin, TX and municipalities in New York state have added requirements during bird migration seasons that promote turning lights out and amber sources. Here is more information about a recent DLC whitepaper on non-white light sources for outdoors.
  • Miniaturization of high output fixtures. More exhibitors than I could count were showing linear high bays as small as 9” x 15” to replace 2’ x 4’ linear highbays. There were also numerous 9” diameter UFO’s (round high bays) intended to replace round HID highbay fixtures, up to 2’ in diameter.
  • Tape manufacturers said A/C COB tape is finally in development and expected to have it in the next year. This will have all of the benefits of COB tape (no pixilated dots) and no separate brick driver to hide.
  • RGB+tunable white (TW) everything! The coolest example was S14 lamps (for outdoor light strings) with RGB+TW that both color changes and color tunes via a mobile app. I saw a couple manufacturers with this, including American Lighting.
  • Some of the RGB+TW luminaires are now being controlled with SPI protocol, which is similar in some ways to DALI’s individually addressable luminaires. SPI is a common communication protocol used by many different devices. For example, SD card reader modules, RFID card reader modules, and 2.4 GHz wireless transmitter/receivers all use SPI to communicate with microcontrollers. One unique benefit of SPI is the fact that data can be transferred without interruption. Any number of bits can be sent or received in a continuous stream.
  • QR codes everywhere! Very little printed product literature, no more thumb drive product catalogs. Almost every both had product signs with QR codes.
  • A new cast of first-tier booths. Acuity didn’t exhibit. Crestron had one of the largest booths. Signify and Cooper had separate but adjacent booths, despite the acquisition. By contrast, Current brands (GLI brands in Current-speak) and its acquired Hubble Brands (HLI brands in Current-speak) were mashed together in a single, large booth. Many people thought the brand reorg was messy and confusing (myself included).
  • One of the most fascinating product demos that I observed was by Dr. Dinesh Ramanathan, Ph.D., the CEO of NexGen Power Systems, an advanced driver manufacturer, that recently emerged from stealth mode. They grow their own GaN-on-GaN, higher frequency transistors that are more efficient, smaller, and produce less EMI, thereby requiring smaller/less EMI filtering components. The resulting drivers are 6% higher power efficiency, which enables luminaires to increase lumen output by 250% (2.5x increase) while decreasing in size! Their drivers were 30-50% smaller in size, in addition to the higher efficiency. I’ll be closely watching this technology.
  • This is the first LightFair that I ever found something exciting in emergency lighting. Concealite showed emergency lights that rotated out of a blank wall when triggered. The product can be painted or wallpapered to be invisible when not in use. They claimed they can replace 8-10 legacy “bug-eye lights” with a single one of their high output, aim-able units. More information here.
  • SportsBeams released a 1500W LED sports light and high mast light, equivalent to 3000W of HID (but such an HID never existed). They use heat pipes for thermal management. They also were offering amber versions of their products, as well as RGB+TW units that enable colorful entertainment lighting from stadium lights. More information here.
  • Filament HID replacement lamps from several manufacturers, including Signify, TCP, LEDVANCE, and others. More about this trend here.
  • Multiple manufacturers promoting Electric Vehicle (EV) chargers, including, Espen Technology and Light Efficient Design. More about this trend here.

Chinese Trade Rebounds In May With Eased COVID Restrictions

China’s trade growth rebounded in May after COVID restrictions that shut down Shanghai and other industrial centers began to ease.

China’s trade growth rebounded in May after COVID restrictions that shut down Shanghai and other industrial centers began to ease. Exports surged 16.9% over a year earlier to $308.3 billion, up from April’s 3.7% growth, a customs agency statement said Thursday. Imports rose gained 4.1% to $229.5 billion, accelerating from the previous month’s 0.7%.

China’s trade has been dampened by weak export demand and curbs imposed to fight COVID outbreaks in Shanghai, site of the world’s busiest port, and other cities. Consumer demand was crushed by rules that confined millions of families to their homes.
