Oxfam required an LED solution to replace their fluorescent lighting and deliver a retail lighting scheme that delivered contrast and depth to their store. This meant switching from harsh, flat fluorescent lighting to a Lietcorp LED solution.
The project objectives were to achieve an average of 700 lux throughout the stores and create a high street retail ambience in the café and breakout areas, whilst achieving a significant reduction in energy, lamp and FM costs.
Our lighting designers produced the lighting scheme specifying Liet D-Series, as the best LED solution for this retail application. We worked closely with Oxfam to ensure that beam angle, colour temperature and lighting control matched the incumbent CDMT technology.
The new fittings were perfect for the retail look of the store and offered a long-lasting alternative to the legacy CDMT technology. As well as consulting in the early planning stages, we offered a full LED lighting package including support and training to Oxfam’s electrical installer.
49 No. 70W CDMT lamps and 44 No. 38W 4ft T8 tubes were replaced by the following LED light engines:
– Liet D20: 12W, 4,000K, 36 degree, 90,000 hour L70 life
– Liet D35: 18W, 4,000K, 36 degree, 90,000 hour L70 life
– Liet D50: 28W, 4,000K, 36 degree, 90,000 hour L70 life
– Annual operating cost (electricity, lamp & FM) before LED per store £1,819
– Annual operating cost (electricity, lamp & FM) after LED per store £340
– Annual cost saving per store £1,479
– Annual carbon reduction 4 tonnes
– Payback (after ECA) 3.6 years
– CAPEX Required £7,000
– Capitalised over 5 years total profit uplift per store £395
Note: all payback and saving calculations exclude: 1) any facilities management savings associated with call-out charges to change lamps 2) air conditioning savings associated with the low heat of Lietcorp’s LED lighting
