CASE STUDIES

Foxlow, Chiswick

March 2016

Brief
- To convert all the Front of House lighting (bar and restaurant) to LED technology
- To make certain areas of the restaurant brighter
- To keep using the existing dimmer

Work Carried Out
- Undertook a lighting survey to show how much electricity and money could be saved over a 5 year period
- Trialled different lamps to find the best solution from a brightness and aesthetic point of view
- Carried out extensive dimming tests with different lamps to find compatible lamps for the old dimmer pack. We then needed to modify the dimmer pack to allow for the low loads that were being placed on it
- Removed old lamps and installed LED lamps
- Reprogramed the dimmer settings at night to achieve the desired light levels

Costs
Previous yearly spend on old lamps and electricity – £2,926
Current yearly spend on LED lamps and electricity – £622
Labour for conversion – £540
Predicted savings made over a five-year period – £10,980
