John Lewis began in 1864 with the opening of the first shop in London's Oxford Street. Through the efforts of its 81,000 partners, John Lewis was awarded 'Retailer of the Year' in 2011 and has succeeded in becoming the largest department store retailer in the UK, with 39 John Lewis shops (30 department stores and nine John Lewis at home) and a growing online business.
John Lewis has long believed that commercial success is directly linked to being a good corporate citizen and is committed to its founder's ideals through its corporate social responsibility (CSR). To build a successful, sustainable business in today's competitive market, John Lewis aims to develop long-term relationships with both customers and suppliers.
Selecting a high performing and aesthetically pleasing lighting solution while respecting the organisation's culture meant research was key. As such, John Lewis partnered with GE Lighting for the initial trial of LED technology and for the final installation at its new Ipswich store using GE's Infusion™ modules.
"The biggest thing for retailers is having the confidence to convert to LEDs," explained Barry Ayling, Lighting Design Manager at John Lewis. "Five years ago there were lots of LED expectations that weren't met and even only eighteen months ago, the cost of LEDs was still very prohibitive."
The decision for John Lewis to move to energy efficient LED technology was motivated by its CSR goal to reduce energy consumption in its stores by 20 percent in 10 years but not without extensive research and the successful 18 month trial period.
When it came to installing LEDs in the new Ipswich store, John Lewis had very specific criteria for the lighting scheme. This included a colour temperature requirement of 3000K warm white combined with precise light control via a 15-degree narrow beam optical system. Furthermore, since LED technology continues to evolve, the new lighting scheme in the John Lewis store had to be easy to upgrade in the future.
To meet these requirements, John Lewis opted for luminaires supplied and adapted by Edge Lighting, incorporating GE Lighting's Infusion™ LED modules. The LEDs were installed throughout the store including the shop floor, office spaces and warehouses.
The twist-in GE Infusion™ LED module enables the entire LED engine to be removed and upgraded in seconds, ensuring the new lighting installation is completely future-proof. An ideal solution for John Lewis, it means the team can simply choose to upgrade at a time when it is suitable to do so.
Designed for both ambient and accent lighting, GE Infusion™ is one of the most flexible lighting solutions on the market, with applications extending across many different types of luminaires. A common base design opens the door to dozens of different design possibilities, allowing creative freedom for a wide range of environments.
In addition and absolutely crucial for a retail environment, the GE Infusion™ modules deliver outstanding quality of light. Modules are available in 800 to 4500 lumen versions, 3 different colour temperatures and 80+ and 90+ CRI (R1-R14), matching all retail application needs.
Results and benefits
"We opted for GE Lighting's Infusion™ LED module because, not only did it meet all of John Lewis' lighting criteria, it had a twist and lock capability, which I wanted to embrace," Barry Ayling explained. "This means we can re-lamp easily and just replace the LED engines for future energy saving and also if we need to change the beam angle or colour temperatures to suit the product"
The lighting average benchmark across the John Lewis business is 30W/m², based on ceramic metal halide lights.The equivalent figure for the all LED Ipswich store is just 10W/m². This has resulted in a 67 percent reduction in electricity demand for lighting.
The implementation of LED has been such a success that the John Lewis team are already planning to utilise the new GE Infusion™ Modules coming to the market in early summer 2013, to make the most out of the extended variety of the modules. This will mean John Lewis can further improve upon the existing energy savings and develop the lighting scenario to match the display of the merchandise.
Along with the clear environmental benefits, the GE Infusion™ modules ensured that the retail experience for John Lewis' customers was significantly improved. The LEDs deliver a bright, clear, white light that aids visual comfort and ensures colours are true to life.
"The shop staff, customers, procurement and CSR teams are all happy and aside from the performance of the LEDs – the clear, bright, white light has created great contrast and a lovely ambience within the store," concluded Barry Ayling at John Lewis. "LEDs are working for us and after the success at Ipswich, we now only consider LED as the solution of choice for all new and refurbished John Lewis stores."
