Our customer

A household name in the UK, John Lewis department stores operate throughout the UK and are owned by the John Lewis Partnership. The retailer's flagship store on Oxford Street is the largest branch in the partnership and was one of the first stores to benefit from a retrofit with GE Lighting lamps.

The expectation

GE CMH Ultra Lamps - John Lewis 6

As the European Union continues its phase-out of inefficient light bulbs, it's crucial that retail applications start making the switch to modern alternatives, as traditional lamps in situ may no longer be available when it comes to eventual replacement. In addition - the sooner the switch is made, the sooner retailers can reap the benefits of energy efficient lighting.

The solution

GE Lighting's CMH Ultra range has been designed specifically for retail environments, providing high efficiency, long life and superb overall lighting quality – ideal for enhancing retail displays and optimising merchandise illumination. The ConstantColor CMH Ultra lamps last 25% longer than comparable products on the market, significantly extending maintenance cycles to achieve long term cost savings.
