MLB Team, Seattle Mariners' Safeco Field Lit with LED Luminaires
SSL Design News Staff

January 21, 2015...The Seattle Mariners have installed LED lighting at Safeco Field. PlanLED produced the LED luminaires that the Major Leaque Baseball team used to replace 600 of its high intensity discharge lights. PlanLED has already installed LEDs in several projects including a number of buildings for Boeing and other companies.

Company founder and CEO John Hwang estimates that the luminaires will consume about 60% less electricity than the HID lighting that it replaces. The company has also installed the bright and efficient LED lighting in the Mariner clubhouse. After the new LED lighting was installed, lighting engineers tested the light levels throughout the field. They found that the light levels met or exceeded MLB lighting standards.

pureLiFi Raises £1.5 million in Latest Funding Round
LIGHTimes News Staff

January 20, 2015...pureLiFi of Edinburg, UK, has raised £1.5 million in its latest round of investment. The 2012 University of Edinburgh spin-out is currently valued at over £14 million. The company says that a VC funding round is on-going, and additional funding announcements are expected during the second half of 2015.

The funding news comes as pureLiFi ships its first full wireless Li-Fi networking system. Li-Fi – a term created by the company's chief science officer (CSO), Professor Haas, refers to a visible light communication technology that provides full networking capabilities similar to Wi-Fi, but can have significantly greater spatial reuse of bandwidth.

London & Scottish Investment Partners (LSIP), a Scottish-based angel group led the latest funding round. Corporate finance firm, Quest Corporate managed the additional funding, which came from the Scottish Investment Bank (SIB) and Old College Capital. pureLifi plans to use the investment to support the development and roll-out of the product roadmap in addition to its marketing and sales.

In Q4 of 2014, the pureLiFi team launched and shipped the Li-Flame, the first Li-Fi network product, to customers globally. The system enables off-the-shelf light fixtures to become Li-Fi access points, which can simultaneously bi-directionally communicate to numerous users. Li-Flame also consists of the first battery-powered Li-Fi mobile unit. The unit attaches to a laptop screen for user roaming within a room or an entire building.

Professor Russel Griggs, pureLiFi’s Chairman, said, “I am very pleased that the necessary funding is now in place to allow Harald and his team to push ahead with the product roadmap, positioning pureLiFi for its next phase of growth.”

Harald Haas, CSO and co-founder of pureLiFi, said, “Li-Fi is increasingly viewed as a transformative technology that can change the way we use the mobile internet as part of future 5G cellular networks and at the same time be an enabler of the emerging Internet of Things.”

Ontario Rinks Getting LED Lighting with the Help of Scotiabank and Delviro Energy
SSL Design News Staff

January 15, 2015...Scotiabank and Delviro Energy of Toronto have teamed up to upgrade the lighting of 13 community rinks across Ontario. Delviro Energy is a Canadian manufacturer and supplier of LED lighting products.

"Scotiabank is proud to be working with Delviro Energy to offer local community rinks new environmentally-friendly lighting," said Ed Keohane, Scotiabank Senior Vice President of Ontario Region. "This is a special partnership for us as it allows us to combine our support of community hockey with our efforts in supporting sustainable, energy-efficient projects, which we do through our Scotiabank EcoLiving program. The new lights will help the arenas save money by saving energy and reducing the impact on climate change."

Scotiabank has offered $5000 to update the lighting in each location with the new energy efficient Delviro Energy lighting. Scotiabank made the offers to the skating rinks in Toronto at the George Bell Arena, in Stratford at the William Allman Memorial Arena and Stratford Rotary Complex (2 rinks in the complex), in Quinte West at Duncan Macdonald Memorial Gardens, Frankford Arena and Trenton Arena Two, in Georgina at the Ice Palace (two rinks at the arena), in Milton at the Milton Sports Centre (in two rinks) and the Milton Memorial Arena and in Sutton at the Sutton Arena.

The LED lighting is expected to help the arenas reduce energy costs by at at least 75 percent compared to incandescent lighting. The new lighting is also expected to reduce maintenance costs with a projected lifetime of 35 to 50 times as long as incandescent and 2 or 3 times as long as fluorescent. The arenas can expect further money-saving benefits from the reduced cooling costs because LEDs produce very little heat.

"We are excited to work with Scotiabank on this project to help light up community rinks for years to come in a way that benefits the environment," said Pat Morrison, national sales director of Delviro Energy.

Vickers Laboratories Gets LED Lighting from MHA Lighting
LIGHTimes News Staff

January 15, 2015...LED lighting from MHA Lighting has helped Vickers Laboratories Ltd., a leading manufacturer of custom special effects for blockbuster movies, reduce its lighting energy consumption by 73%. Vickers Laboratories Ltd based in Leeds, UK, is a chemical manufacturing facility that produces custom special effects for famous film, TV and theatre production companies. In its laboratories the company created the famous chocolate river in Tim Burton’s Charlie and the Chocolate Factory starring Johnny Depp, and the “ewe’s milk bath” for Charlize Theron to emerge from as the Evil Queen in 2012’s Snow White and the Huntsman.

The chemical manufacturer also supplied variety of goo and gunk for films and TV series that became realistic special effects for scenes in Doctor Who, Clash of the Titans, Sweeny Todd, and Emmerdale.

Vickers Laboratories Ltd also produces the monomer used in the manufacturing process of the latest generation of Silicone-hydrogel contact lenses, sold under the OPTOMER® brand.

To meet the Increasing demands for their products, lab bosses needed to design a specialized manufacturing facility adjacent to the existing site to increase their capacity. High quality and uniform light as well as high color rendering were key design considerations for the new lab to ensure that staff could create their products and perform true color inspection within a well-lit environment.

MHA Lighting's LightStar202 LED luminaires reduced the overall lighting energy consumption in the area. The luminaries also provide an estimated lifetime saving of £8,333. The LED luminaires also improved Lux levels in the lab with the LightStar product providing 500 lux to the work spaces and equipment.

MHA Lighting MD Tom Harrison said, “Our new LightStar luminaire is one of the most ruthlessly efficient products on the market. We believe it is unrivalled in light quality and distribution and energy efficiency. It is also incredibly versatile – allowing the client to select from a range of wattages (15 to 121w) to deliver between 100 to 123 lumens per circuit watt and providing a total lumen output of between 1845 and 12100. Combining this high performance with un-rivalled light distribution from the luminaire enables us to install fewer fittings too, creating a multiplier effect in terms of energy savings and payback periods for clients like Vickers Laboratories Ltd. We are delighted that this has been such a successful project. It has been a pleasure to work alongside the Vickers team in devising a ‘made-to-measure’ lighting scheme for their brand new laboratory.”

The LightStar 202 (Diffused) specified at Vickers Laboratories consumes just 43W (with the ballast). The light engine can also be driven at a range of wattages to increase or decrease light levels. MHA designed its sealed LED lighting units to stop dust and insects from gathering around warm light fittings and ensuring a clean laboratory area, which is essential for the production of materials for medical devices such as contact lenses. The luminaire's 66,000 hour minimum life span means that regular maintenance and bulb replacement are vitally eliminated. MHA says that the lifespan can further be increased to a minimum of 109,000 hours if the driver is replaced at 66,000 hour point.

MHA’s installation includes two occupancy sensors to further maximize lighting energy costs savings.

Steve Foster, Vickers Laboratories Ltd’s Managing Director, said that switching to LED lighting was part of the company’s strategy to improve light levels in their labs while ultimately reducing associated energy costs. Steve commented, “Vickers Laboratories Ltd manufactures production chemicals for some of the biggest pharmaceutical and contact lens companies in the world, so quality assurance is absolutely essential. Complicated chemical processes are required to take place to create these products and so it is imperative that light quality and light uniformity is at the highest standard possible for our precision working. We knew that we needed to source lighting that would not only cut our lighting costs, provide a short payback period and offer long-term energy savings but also wasn’t over-the-top on capital cost. MHA handled the proposal and installation process with great detail and efficiency. We are delighted with the results.”

DOE Publishes Gateway Report about Survey of SSL Use in Museums
SSL Design News Staff

January 14, 2015...Since 2011, museums seeking guidance in converting to SSL have looked to Jim Druzik and Stefan Michalski’s “Guidelines for Assessing Solid-State Lighting for Museums”. In June 2014, the Pacific Northwest National Laboratory (PNNL), sent out a total of 979 questionnaires to members of the museum community who had requested a copy of the Guidelines. PNNL sent out the questionnaires on behalf of the U.S. Department of Energy (DOE), the Getty Conservation Institute (GCI), and the Canadian Conservation Institute (CCI). The questionnaires generated 46 sets of responses for a 4.7% response rate.

These responses yielded insight into how LEDs are being employed in museums, and what progress and obstacles have been encountered in the process. The GATEWAY report, SSL Adoption by Museums, includes museum requirements and goals, incorporating sustainability and energy savings issues related to lighting; initial concerns and resolved misconceptions about LED technology. The report looks at the current lighting that museums use to examine how the Guidelines have been adopted so far. While 68% of the respondents placed a high priority on energy efficiency, respondents indicated that their museums would not risk potential damage on their works of art nor sacrifice lighting quality in their galleries solely for the sake of energy efficiency.

Since 2009, LED use in at least part of a museum has increased from virtually none to nearly 40 percent. However, the use of incandescent bulbs as the primary lighting source only decrease marginally from 55 percent in 2009 to 51 in 2014. Of 2014 respondents, 13 percent said they used compact fluorescent (CFL), 11 percent used linear fluorescent, and 22 percent primarily employed other lighting (including daylight, metal halide, and halogen).

When asked whether they would consider and implement another LED installation, 71% indicated they would, only 6% would not, and 32% said they already had.

Respondents indicated that the main considerations in selecting lamps were color, spectral power distribution (SPD), and damage potential. Following these were lamp efficacy, initial cost, and form factor (lamp size and shape). Some museums also prioritized the reliability of the manufacturer.

While 75% of respondents experienced early LED product failures, the maximum failure rate reported was just 2.5% of the installed lamps or fixtures. Sources of the failure in these cases included electronic components such as drivers and power supplies, but not the LED source itself.

The respondents cited several main barriers to adopting LEDs in museums. Among them:

•Potential high cost, especially for dedicated LED fixtures;

•Difficult selection process, due to the confusing variety of products and difficulty keeping up with rapid advancements in technology;

•Resistance to change, especially from conservators and university administration; and

•Technology limitations, such as poor dimming performance and potentially problematic performance of LED replacement lamps in enclosed fixtures.

Respondents showed no strong preference for replacement lamps over dedicated LED fixtures. Instead, the decision of using replacement lamps or dedicated LED fixtures depended on the application and the pressure exerted by existing luminaire stock.

When evaluating color, almost all considered color rendering index (CRI), with target values greater than 85; two-thirds favored correlated color temperature (CCT) with 2700 and 3000 K listed as target values; and 60% evaluated the light source SPD. Just 26% had to have a color warranty. Respondents said they grouped luminaires of similar color shift to resolve color inconsistencies or they had manufacturers replace the luminaires.

Two thirds of respondents trialed light sources to and expected illuminance levels in the actual gallery. Less than half used a reserved space for mock-ups only.

When evaluating potential damage, the majority considered UV and IR output and about half considered short-wavelength emissions in the SPD. Other considerations included the composition of the displayed materials and limiting the duration of exposure to LEDs, CCT, and heat output. Almost all respondents considered light exposure recommendations based upon the sensitivity of the materials displayed, along with the annual hours of operation of the lighting system.

Dimming was generally believed important to achieve required low light levels down to 5 fc (50 lux) incident on the object. Of respondents, 42% used DALI/ DMX (Digital Multiplexing)/or 0-10V dimming protocol, 39% used dimmers designed for incandescent loads, and 33% had no dimming capabilities in galleries (12% used a combination of dimming methods). Problems for dimmers not designed for incandescent loads included flickering or failing to turn on.

The questionnaire responses and comments revealed considerable confusion about different LED products, what museum staff should be asking for, and concerns about maintenance. The responses also made clear that education and experience are needed at multiple levels.

The report points out that in general, white LEDs pose no special color issues (in rendering nor increased damage potential) for works of art, compared to an equivalent CCT halogen or fluorescent source. In fact, the report notes that at equal illuminance levels, the photochemical, thermal, and hygrometric stresses posed by LEDs are lower than halogen and (photochemically) much lower than daylight. The report notes the strong correlation between damage potential and CCT of all products.

The report asserts that lighting controls can eliminate 60% or more of wasted lighting energy in buildings and would allow lighting designers to specify lighting exposure (illuminance, spectrum, time) to minimize damage while offering conditions for optimal viewing. Fortunately, the report says that companies are producing a growing number of more sophisticated controllable LED light sources and complementary control technologies.

Streetlights in Delhi to be Replaced with LED-based Models

January 13, 2015...All 500,000 street lights in Delhi will be replaced by LED lights within 1 year, saving over Rs. 10 billion over a 7 year period, according to Shri Piyush Goyal , Union Minister of State (IC) for Power, Coal and New & Renewable Energy.

Shri Goyal attended the ceremony of signing of MOU between South Delhi Municipal Corporation (SDMC) and Energy Efficiency Services Limited (EESL) in Delhi for replacing 200,000 conventional street lights in the SDMC area with energy efficient and smart LED lights at no upfront capital cost to SDMC, a Business Standard article reported.

Prime Minister Shri Narenda Modi launched a national LED lighting program on January 5th, 2015 in which initially 100 cities in India will be covered with LED Lighting.

Inspired by the Prime Minister's announcement, Shri Goyal said that the nationwide installation will be finished in 3 years. The Business Standard article also noted that Shri Goyal said that EESL and SDMC signed an agreement within 4 days of the Prime Minister's announcement.

The more efficient LED-based streetlights can provide more light output while consuming the less power. The article gives the example of an LED luminaire that replaced a 150W sodium lamp and increased the luminescence over ten times from 30 Lux to 312 Lux.

SDMC expects that the new LED-based street lights will consume up to 70 percent less electricity. SDMC further says that the savings will total over 5 billion rubles over 7 years. This will reportedly be more than three times the cost of purchasing and installing the LED streetlights.

SDMC's repayments to EESL will come from its savings in energy and maintenance costs over a 7 year contract period. Also as part of the agreement, EESL will provide free replacements and maintenance of lights at no additional cost.

In Naraina, Laxmi Nagar and Malaviya Nagar areas street lights have already been replaced with LED-based street lights.

As part of a separate initiative called the pan India home lighting program, a domestic energy efficient lighting program for Delhi plans to distribute 10 million energy efficient bulbs (with 7 year warranty) for an expected savings of more than Rs. 10 billion over a 7 year period.

Plexineon Luminaires from iLight Technologies Accent Façade of New Portland, Maine Hotel
SSL Design News Staff

January 9, 2015...iLight Technologies reported that its LED luminaires now help illuminate a new Hyatt hotel in the historic part of Portland, Maine. The seven-story, 130-room Hyatt Place Portland-Old Port hotel sits along the waterfront with shops, bars, and restaurants. The rectangular building has a contradictory styled, faceted-glass corner entrance.

Greg Day Lighting worked with architecture firm Canal 5 Studio to design a lighting scheme that could emphasize precision and the rectangular pattern of the building's façade. The group decided to place horizontal Plexineon White luminaires randomly on the building façade that stretches down from the penthouse and continues along one side of the building. The luminaires are visible by day and they form dashes of light at night. The building uses a total of 76m of Plexineon linear luminaires.

“The Plexineon becomes like sparkly jewels to contrast with the masculinity of the building,” Greg Day said. “It’s part of a very Fred and Ginger dance: there’s the curve of the hotel with freeforming glass and the flat, ordered panels.”

“We could have hidden them between the gaps in the compressed stone siding, but we made a conscious decision to make them visible by day,” Day said.

Patrick Costin, Principal at Canal 5 Studio, agrees. “The iLight permitted us to add texture and detail to the façade during the day and a distinctive identity to the building at night.”

The warm white light from the Plexineon luminaires adds an additional point of contrast along the city's streetscape.

Costin says, “We appreciate the pure expression of light the fixture provides.”

Day, who calls it “linear sparkle” said he’s delighted with the result. “It ended up being the right balance between a visible light source and adding that interest we wanted.”

GrooveBoston Show at UTA Employs Robe Fixtures
SSL Design News Staff

January 8, 2015...The GrooveBoston dance appeared at the College Park Center at the University of Texas Arlington (UTA). Nathan Almeida of East Coast Lighting & Production Services (ELCPS) and GrooveBoston Production Director Ed Slapik created the spectacular lighting and production design.

For the last ten years, Almeida has been involved with lighting the legendary college-oriented EDM experience. EDM is renowned for awesome visual environments, high production values, and some of the best dance sounds. For this year’s show, Almeida once again employed Robe Pointes, CycFX 8s and LEDBeam 100s.

Create a new look for GrooveBoston was a priority. The venue offered plenty of stage space and headroom. The crew employed a trussing structure to make up the main set architecture and ensure an efficient get-in and set-up in a tight timeframe. The trussing structure design was based on the concept of a ‘Phoenix rising’ in which Trussing ‘wings’ were diagonally raked on either side of the centre position, and the upstage video screen became the ‘body’.

Almeida chose 12 x Pointes, 16 x CycFX 8s and 6 x LEDBeam 100s, from Robe’s ROBIN range of luminaires. He first selected the fixtures with the wings of the phoenix in mind, thinking that CycFX 8s would showcase them perfectly.

In the past he used other LED battens to highlight the truss. However, he chose to use the automated tilt function of the CycFX 8s to bring movement to the equation and animated the visual picture.

The Robe Pointes created all of the main lighting looks and drama. “The extraordinary optics, zoom and prism functions all enabled me to fill a large space with a minimal amount of fixtures,” he said.

The compact LEDBeam 100s - fitted with 25 degree lenses - were used for artist key lighting and produced a focusable even field of light to illuminate the DJs from above.

Almeida’s current favorite Robe fixture is still the Pointe. He loves everything about Pointes and their overall diverse functionality.

One Pointe can go a long way with a lively imagination … and this is one of the many special features characterising his ongoing GrooveBoston designs.

He used zoom of the CycFX 8s at UTA which allowed him to light from the very high trim using the lenses narrowed down.

“I think Robe is right at the top of their game at the moment,” he commented. “You can see and appreciate that a serious amount of time and thought is going into R & D ... and this is definitely paying off.”

He programmed and ran the UTA show with a grandMA2 full-size console and a light for backup.

ECLPS supplied all the lighting, but they used the house LED screen. GrooveBoston provided the audio and Dynamic Lasers supplied the lasers for the show.

Jason Slomovitz was the show’s Creative Director, Bianca Mauro the Production Manager and Jay Nightride coordinated and operated the video content.
