SHINING EXAMPLES

Collingwood Lighting’s products and expertise have successfully been put to good use on a number of public sector, private residential and commercial projects, perhaps most notably of which as part of a multi million pound development at Newcastle University.

Collingwood’s products were installed as part of a £300 million development at Newcastle University. James Davison at Atkins, lighting designer for the works, explained: “The project is part of the University’s Coherent Campus and sustainability programme which aims to improve the spaces between buildings to create a sense of place that is welcoming, with well designed and well linked social spaces.

“The challenge was to find a solution which provided a space which fitted with the landscape architects, university, conservation and planners - due to the sensitive nature of the surrounding buildings, as the University is steeped in history, dating back to 1834. Everything from the diameter and colour of the cable sheath to the protrusion and visibility of the fittings was submitted in detail alongside hand drawn sketches and temporary installations to demonstrate the scheme.”

Barry Hutchinson at Atkins, co-lighting designer of the scheme, observed: “The works exclusively utilised energy efficient LEDs from Collingwood Lighting, which are virtually maintenance free with excellent colour rendering. They are also significantly smaller than the traditional discharge lamp fittings. The colour rendering is particularly important as it emphasises the light/dark contrast and picks out more detail in the subjects to be illuminated.”

The entire site was built up using 3D modelling software to plan calculate and demonstrate not only the lighting levels achieved but also the effects of the proposed luminaries. This was backed up by numerous night visits to site in all weathers where temporary lighting rigs were established to enable final setting out details to be confirmed and demonstrate the expected effect of the proposals.

The project involved the use of a wide range of techniques and installations due to the number of contrasting building styles. A total of 91 Collingwood Lighting LEDs comprising a selection of universal, powerful and adjustable Luxeon LED ground fittings were installed. Combining sleek aesthetics; stainless steel brackets with outstanding LED light output and a rating of IP68, meaning they can be fully submersed, the fittings were ideally suited to complement the University’s architectural form.

Strategically placed around the perimeter of the University, the lighting solution highlights particular prominent features from decorative paving, challenging staircases, colourful foliage and tree pits, street furniture, artwork and sculptures, which all assume space between a mélange of listed buildings.

Len White of the University added: “The result is an improved and more uniform lighting scheme with vastly enhanced colour rendering. The lighting scheme is maintenance free due with a reduction in energy use when compared to ‘traditional’ discharge lamp schemes, successfully meeting the brief.”

Well suited for use in commercial applications, Collingwood’s lighting solutions work just as well in private residential projects too, as can be seen in the recently completed Long House project in Lindsey, Suffolk.

Used to deliver both practical and decorative lighting throughout the building, a series of Collingwood’s LED ground lights and uplighters have been used in both indoor and outdoor applications.

A combination of Collingwood’s GL008 and GL038A were used to highlight elements of the stunning exterior fascia and gardens – being installed outside, these ground lights in particular were used due to their robust nature. Combining toughened walk over safety glass and marine grade stainless steel these exterior fittings made perfect sense. The LEDs themselves can also be specifically angled to focus on the chosen element - in this case to illuminate the front of the building and several trees within the beautifully landscaped garden.

Internally, Collingwood’s GL019 and GL040 LEDs were used to help draw special attention to period features including beams, walls, stairs and doors. Manufactured with an attractive stainless steel finish, these fittings offer an outstanding aesthetic that works well with the surrounding décor of The Long House.

Ipswich based electrical contractor, Electricare Contractors Ltd worked on the project and Director, Ben Allen was instrumental in gaining Collingwood the specification. He said: “We were looking to achieve an energy efficient solution and wanted fixtures that weren’t intrusive once in place. As lighting specialists, working on projects from the very first consultation through to handover, we consult with the client directly to ensure we deliver a tailored solution to meet their needs. Owing to our all-encompassing approach, applying careful consideration to the lighting/technical design before carrying out the actual lighting installation, we are able to eliminate the need for separate designers and electrical installers to be involved. With these points in mind, we selected Collingwood’s discreet yet powerful, GL range of LEDs as we were confident they would be right for the job.

These were ideal for this project as it was possible to achieve varying lighting levels, depending on where the lights themselves were installed. A series of the GL038A LEDs for example, were used to light up several trees surrounding the house. These flood lights run at just 4W, yet supplied ample output to light the trees to stunning effect – offering an energy efficient solution that achieved the desired result. From an aesthetic perspective, we were able to blend the contemporary look of the lights with the traditional appeal of the building by using modern stainless steel fittings against a traditional oak backdrop – this delivered a stunning end result.”

He continued: “By using indoor or outdoor fittings where required, we were able to use the same LEDs throughout which is testament alone to their versatility. This helped speed up the installation process for us meaning we were able to complete the project in good time – a point of particular note considering the residential nature of the project.”

From an energy saving perspective, Collingwood Lighting really comes into its own – by changing existing fittings at the Royal & Derngate Theatre for a selection of its own LEDs, Collingwood has helped the theatre achieve a staggering 50% reduction in utility costs from when the project commenced.

Mike Chisholm, maintenance technician at Royal and Derngate Theatre said: “For any theatre, the lighting scheme is crucial to enhance the visitor’s experience. Added to this, the large electricity bills a building of this size incurs meant we had to address the current lighting design.

“Over the last four years we have been installing LEDs from specialists Collingwood Lighting around the building, which has culminated in a saving of over £35,000 a year already.”

The revamp of its lighting technology is still in progress as Royal & Derngate replace all the dichroic GU10 fittings across the building. The switch to Collingwood is intensive and already incorporates all of its foyers, bars, the Royal corridors and auditorium pass corridors.

The theatre has replaced its old dichroic 50W fittings with a combination of LED’s from Collingwood’s portfolio, including the LL030’s and LL090’s and 21 Watt PowerLED ARIII light units, along with the replacement of 70W HT fittings with 18W LED linear bars. In addition, strip lighting was substituted with high powered light source RGB flexible strip led lighting.

“The size of our building is one million square feet and we are now fully into Band B rated 40. Four years ago we were in Band D rated 100, and this would of course be typical of a building of our size. From our latest electricity bill, it works out we have a 50 percent saving compared with four years ago, which is tremendous,” Mike added.

“Our next project was the main auditorium, where we still had 100 50W dichroic lights. By changing them to a 6W Collingwood LL090 LED flood light, we will save 4.4kilowatt-hours over an 18-hour day.

The pay back was quick - just by replacing 100 dichroic in that space we saved a further £3,000 a year on our bill.”

Combined with this, the theatre’s maintenance costs have been reduced and lighting quality improved throughout the building. The average lifespan of a dichroic unit is between 2,000 and 4,000 hours, which equates to approximately three to four individual lamp changes per year. Having replaced this with the high quality LEDs, the theatre has saved over £600 on new lamps so far, decreasing labour costs previously associated with constant re-lamping.

Mike Chisholm adds: “It’s good for the environment in other ways too, as we are also saving on carbon emissions. With the increased life of the units we aren’t contributing to landfill - or being charged for recycling lamps. In addition, the low heat of the LED units means a much lower fire risk.”
