UK Supermarket Group - Cold Storage

Late in 2007 Light Planning Techniques Ltd. (LPT), a Metrolight UK partner, approached the Chief Executive of one of the UK’s largest supermarket groups. LPT offered to save over 35% of the Group’s lighting energy costs in the Company’s 12 Distribution Centers where Metrolight technology could be implemented. Early in 2008 a trial of 20 retrofitted luminaries was commissioned at one of the Distribution Centers.

• Number of Luminaries - Reduced by 33%
• Lamp Power - Reduced from 400w to 200w (Fully controlled dimming)
• Improved Color Rendition - Shift from Sodium to Metal Halide
• Annual CO2 Saved - 2,936 Tons
• ROI - 70%
• Simple Payback Period - 1.4 years
• Total Annual Saving - £568,000
