Project: TFT Dimming
Dates: 2007 – Present
Sales floor areas have general ambient lighting that is delivered by a fully dimmable continuous row lighting system. The feature lighting is switched off and the ambient lighting is dimmed down after trading hours to save energy, this is one of the functions of the Trend BMS.
To achieve this works involved:
- Removal of non dimmable ballasts and then installation of digital ballasts and eco tubes on every light fitting on the stores Two Floor trading and Travelator areas.
- The TFT was then split into 5 zones with 3 core control run between each fitting.
- Installation of Beckoff dimming lighting panel and then programmed to dim at 3 different levels.
- Reconfiguring and re feeding of TFT lighting circuits so the TFT lights don’t switch with the main sales floor.
This particular project consisted of in excess of 35 stores across the UK with each store having on average 800 dimmable ballasts to be installed and controlled. Each store had a 1 week time frame and the project was to be completed within 12 weeks.
Together with Tesco’s Project Manager all stores have been delivered on time and to a high standard with very positive feedback.
