Energy-efficient LED upgrade

Energy-efficient LED upgrade ‘dramatically’ improves light levels for Highland Spring
The prominent Scottish bottled water supplier has recently implemented high-efficiency, long-life Tamlite LED EXPO products at its 24-hour plant in Blackford, Perthshire.

Established in 1979, Highland Spring Group (HSG) has consistently been one of the UK’s most successful suppliers of bottled water. It operates and maintains factories and warehouses in Blackford, Perthshire and has had a long-standing commitment to maintaining facilities that incorporate the latest and most user-friendly technologies.
This emphasis recently led to a review of the lighting provision at the facility in Blackford, where storage and dispatch of the finished bottled water product takes place. A legacy system of low-bay SONs in various areas of the warehouse had proven itself to be inadequate on several levels. In some spaces light levels were as low as 20 lux, whilst the ‘warm up time’ of nearly 10 minutes for the fixtures was having a negative effect on productivity and general navigation. It was also envisaged that this could lead to serious problems in the event of an extended power outage.

The issues with the existing system had been commented upon by managers and employees alike, so HSG invited John McCormick at BFE Electrical to investigate a replacement specification based around high-efficiency, high-output LED products. Having regularly selected Tamlite Lighting LEDs for all manner of industrial projects, McCormick soon determined that the Redditch-based manufacturer was best-positioned to supply a suitable solution.

“It was clear that there was a great deal of room for improvement at the Blackford warehouse – particularly as the facilities manager pointed out his required minimum illumination level for the new system was 350 lux,” says McCormick. “The potential of Tamlite products to deliver a greatly improved solution quickly became apparent, so I worked closely with our local Livingstone branch of CEF and Tamlite Sales Engineer, Andrew White, to devise a new design based around Tamlite LED EXPOs.”

‘It’s made a dramatic difference’

A popular choice for industrial, warehousing and sports hall facilities, the EXPO LED low bays offer a great deal of flexibility for different applications with a mounting height of up to 20m. Featuring a high-performance optical array and in-house LED boards,, EXPO delivers: a high-output LED low bay; Emergency and VISION control options; CRI: Ra>80; up to 150 lumens per Watt efficacy; and 50,000 hours’ lifetime all designed and built within the U.K.

Energy savings of up to 60% are typically possible with the EXPO fixtures, meaning that Highland Spring will enjoy significantly lower energy bills in the future. The company will also see a reduction in maintenance costs, as the LEDs last much longer and will therefore need to be replaced every five years at most.

And right now, Highland Spring Group is savouring the benefits of what has been a substantial improvement in lighting consistency and quality. Davie Simpson – Site Engineering Manager at Highland Spring explains: “We run a 24-hour plant here. Key to the lighting upgrade has been the requirement for different solutions in the various sectors throughout the plant, due to the specialist requirements of our staff in each sector.

“For example, in the manufacturing hall it is imperative our staff are able to easily read the legal and technical language included in our labelling to ensure we meet every regulation that applies within our industry. However, such high lux levels in the warehouse would be potentially damaging to the sight of our forklift drivers as they look up towards the ceiling during the usual course of their duties.

“The solution that Tamlite Lighting has supplied has met all our specifications and we are very happy with the work they have done to date. Indeed we will be continuing our upgrades in our packaging hall, commencing in September.”

Andrew White concludes, “Being able to tailor our solutions for Highland Spring to the separate needs across their plant has ensured worker safety and health, while also helping them to manage their energy consumption through increased efficiency. We look forward to continuing to support their upgrades throughout the plant.”

Reflecting on a project that saw Tamlite work “very closely and successfully with both BFE Electrical and Highland Spring”, Colin Lawson, Tamlite’s Head of sales, marketing and product development says that the project further underlines the “dramatic improvement to lighting conditions that the EXPO products have delivered to a host of industrial environments. Enquiries about the EXPO range have continued to rise in parallel with the overall growth of interest in LED technology as a whole. We are delighted that the system has worked out so well here and are grateful for Highland Spring’s feedback about the quality and consistency of the new system.”
