Aberfan Post-Office & Convenience Store owner was stunned by the full impact of Dextra Lighting’s cutting-edge LED luminaires on his establishment. His surprise begs the question: what do end-users actually expect from LED lighting nowadays?

DSC_0379(500)

LED lighting has always been surrounded by both hype and skepticism since the moment it took the market by storm. Industry claims regarding its benefits have largely focussed on its energy saving properties and consequently manufacturers have pushed to provide clear and accessible product information and guidance. This task has not been easy as market researchers still report some confusion amongst customers with regards to LED performance (partly due to negative experiences in the early years of LED’s development and the pervasiveness of low quality products). Despite this, customer awareness of LED today, from how returns of investment rates are calculated to the true meaning of cost of ownership, has risen exponentially.

End-users are inevitably preoccupied with weighing manufacturer’s claims against their own practical realities, seeking answers to vital questions such as: “How much will this upgrade actually cost me?”, “How much payback can I really expect?” “Is it really more reliable?”. However, with the general emphasis on cost and energy saving, the question of “how will LED improve a store’s environment?”, can sometimes take a backseat (with the exception of high end/luxury retail outlets and now major supermarkets who have identified a link between better lighting, improved customer experience and increased revenue). The latter question is also difficult to answer as unlike performance data, “look” and “feel” can neither be accurately tested nor represented in exact figures. As a result, it is important for manufacturers and suppliers to highlight the first-hand experiences of customers in the retail sector, to show exactly what high quality LED lighting is capable of.

One of these positive experiences is that of Mr. Bernard McCormack, proprietor of the Aberfan store. As expected, Mr. McCormack was initially attracted to the much publicised energy saving capabilities of LED and approached Dextra Lighting with the intent to reduce his electricity bills. After all, with the exception of his refrigerators, lighting consisted of the main portion of his store’s electrical load. As with many customers, he did not expect any major aesthetic differences apart from a general “refreshment” of the area.

The project began by conducting a thorough survey to ascertain the performance of the existing fittings and determine the appropriate light levels for the shop floor. The previously installed switch-start recessed fittings with aluminium louvres, produced a darkened ceiling effect characteristic of such older generation lighting, whilst the wall racks suffered from what surveyors described as “louvre light cut off” and reduced light above chest level.

The cure for this chronic shortage of light was the ARCUS LED luminaire. This fitting immediately enhanced the appearance of the store by providing a more effective and even distribution of light, whilst simultaneously reducing energy consumption by 62%.

As with all products within Dextra Lighting’s LED range, the ARCUS LED utilises the latest Philips LED sources and drivers, offering excellent energy efficiency and minimal maintenance. These high quality components play a central role in providing the rapid return on investment that Mr. McCormack, like most retailers, are looking for. In addition, the luminaire’s performance is optimised by the highly efficient optic design of its twin extruded polycarbonate diffusers, ensuring that the luminaire makes the most of the LED sources installed, offering an impressive of LOR of 81%. The ARCUS’s optics are designed to create a bright and uniform distribution of light, making all areas of the store equally lit, eliminating unwanted dark spots.

Efficiency and performance aside, the ARCUS LED has been designed to offer a new aesthetic to Dextra Lighting’s LED modular range. Its gull-wing housing and twin polycarbonate diffuser give the fitting itself an attractive modern appearance which has proven increasingly popular amongst customers in the retail sector. The luminaire also offers lumen outputs of up to 8,800, making it ideal for retail applications such as this, but also receptions and high level atriums.

Although Mr. McCormack did not require specific customisations for his refurbishment , the ARCUS LED can be delivered with a variety of options. These include a range of dimming functions (HFR dimming, DALI dimming, Switch dimming and DSI dimming) and sensors (passive infra-red or microwave), which can maximise energy efficiency by adapting to daylight and circulation hours as well as providing clients the flexibility to adjust light levels according to their needs. The luminaire is suitable for both lay-in applications in 15mm and 24mm exposed T ceilings systems. Three hour integral emergency is also available with this product.

The Tydfil based shop has been completely transformed using Dextra Lighting’s state-of-the-art luminaires in a careful and strategic manner. When it comes to “look” and “feel”, LED technology has advanced so quickly in recent years, and both manufactures and designers have responded to the growing demand for lighting aimed at enhancing the hospitality aspect of the retail experience. LED now offers high performing replacements for all existing light fittings types and new ground-breaking designs, all with an incredible choice of colour temperatures, lumen outputs and controls. Although minimising costs is the top priority for most customers looking to upgrade, the aesthetic possibilities of LED are becoming driving aspects in the market.

For Mr. McCormack the results certainly proved more than what he bargained for. In addition to his considerable surprise to the vast improvement, he jovially adds that the new LED lights will now show whether his cleaners have done a good job or not.

Tri-Partnership yields success in multi-site school project

In the spirit of collaboration and new beginnings, Dextra Lighting co-operated closely with prestigious property and construction group, Kier Services and leading U.K lighting suppliers, Newey & Eyre Lighting Design, to deliver the first in a series of extensive lighting upgrades. The multi-site project consists of the refurbishment of a total of 6 schools currently managed by Kier in the Norfolk area. The first step in this joint venture has been an all-round success, with Taverham High School’s sports hall now enjoying the financial and aesthetic benefits of the latest LED lighting.

IMG_9113(500)

Under Newey and Eyre’s strong recommendation, Dextra Lighting were approached by Kier Services (a subsidiary of Kier Group plc, specialising in facilities management and environmental services) to participate in the near complete refurbishment of the academy’s sports facilities. Dextra’s role was to manufacture and deliver the fittings, whilst Newey & Eyre designed the project and Kier Services installed the entire system. The project included not only the replacement of the lighting but also the hall’s entire floor. As the school’s top priority was to maximise energy savings by improving on the existing T5 fluorescent system (which was already operating quite efficiently with a projected 9 year payback), LED lighting was the natural choice. With fittings mounted at a height of 10m, Kier also reported frequent issues with lamp changes and maintenance, which led them to position their staff on-site permanently as part of a 25 year contract with the school.

With this in mind, Newey & Eyre lighting design put forward a scheme using the purpose-built ProSport LED luminaire in a 17,000 lumen capacity and a cool white, colour 84 light temperature for the sports hall. By choosing LED over conventional lighting, the time and cost of maintenance are reduced to a minimum, as LED lights have a far longer lifespan that can exceed 10 years given the right circumstances. LED sources also experience reduced lumen depreciation over time, again eliminating the need for frequent lamp changes to maintain the desired light level.

Taverham High School have invested extensively in renewing their sports hall to provide their pupils with the best possible facilities as well as a rich and varied programme. Many of the academy’s sports students are put forward to join both regional and national teams in a variety of disciplines and the site itself is frequently used to host local-level competitions. As a result, the versatile Prosport LED was selected for the site as it is specifically designed for a variety of high level sports applications; fulfilling the clients requirements for quality, energy efficiency and cost-effectiveness.

Available in lumen outputs as high as 33,000 and a variety of distributions, the luminaire allows indoor installations to provide the appropriate light levels and uniformity of coverage needed to enhance player experience. At 17,000lm, the highly efficient Prosport LED offers an impressive LOR of 80% and operates at an average of 106 Ll/w, comfortably providing the 500 Lux requirements for the area and corresponding activities. Together with the 23,000lm option, this product is a far more efficient next-generation replacement for 3×80 and 4×80 T5 luminaires.

As pupils use the facilities not only for a wide range of sporting activities such as: netball, rounders, athletics, hockey, sports hall athletics, table tennis, but also examinations, the luminaire’s versatility proved to be a significant advantage. The Prosport is designed to cater for such a wide range of activities. For instance, an optional asymmetrical bracket allows the luminaire to be angled to ensure the best light coverage for badminton or tennis courts, whilst the standard symmetrical luminaire is ideally suited for football, basketball and netball applications.

Many of the games held at the sports hall expose the light fixtures to the risk of ball strikes, which in turn can cause damage to the body or shatter lamps. To counter this, the luminaire’s robust steel housing and polycarbonate LED cover offer a first line of protection. Its angled housing is also designed to be both aesthetically pleasing and avoid balls or shuttlecocks lodging onto the rear of the fitting.

In terms of installation, the Prosport LED’s zintec spine allows for a quick and simple mounting and prewired cables eliminate the need to access the luminaire for wiring at such inconveniently high ceilings. Combined, these features reduce the costs of installation for the academy and therefore improve the overall rate of return on investment.

The luminaire is compatible with DALI and HFR Analogue Dimming to allow lights to be adjusted according to different activities held on-site. It is offered with either standard, self-test or auto-test 3 hour emergency lighting to guarantee user safety.

Overall, the design has delivered on its promise to significantly reduce energy consumption, achieve the required 500 Lux with an even coverage and a more refined light quality throughout; all in order to help provide students with a stimulating and revitalised sports environment. These challenges were met whilst offering substantial paybacks not only in energy savings, but in reduced installation and future maintenance costs. The project was so well received that Newey and Eyre insisted on putting the design forward for the Rexel Renewables Award 2015 for Universities & Colleges & Educational Premises, the result of which will be published as the multi-site contract proceeds.

In line with Kier’s ambitious policies regarding sustainable procurement and environmentally conscious waste management policies, the group took full advantage of Dexreco’s luminaire disposal service, which promptly and efficiently oversaw the removal and recycling of all the previous light fittings.

Kier Services, Newey and Eyre and Taverham High School seemed collectively pleased with the solution brought forward by Dextra Lighting and the level of service provided; ticking all the boxes for sustainability, quality and affordability, crucial to any educational establishment. The installation will also reduce Kier the costs of fulfilling their contractual obligations towards the school, as the luminaires require minimal maintenance, which will allow staff to be redeployed in other areas of need. In addition, all Dextra Lighting LED products are offered with a comprehensive 5 year warranty, supporting Kier further down the line in the management of the site. The success of the project has been a testament to the importance of well-oiled collaborative efforts and firm commitment of all parties to provide excellent service to the customer in every department.
