The new lighting system sees the warehouse area divided into 3 main lighting zones. These will then be divided again as necessary in order to best manage the lighting needs for each space. For example, prior to the upgrade, the lights were being left on all day even though employees may not visit certain aisles for long periods of time.
To overcome this, the lighting has been divided into 8 sections, so that installed at roof level (10mts AFFL) control lights in individual aisles. When an employee/forklift enters an aisle, the lights in that area automatically turn on. Then, after a set period of no movement the lights will automatically turn off, saving energy in the process and extending lamp life.
To better utilise the significant natural light available in the area, daylight lux sensors have been installed. These monitor the amount of natural light available and automatically turn on artificial lighting only when necessary.
In conjunction with the lighting control system upgrade, a decision was made to retrofit the existing warehouse lighting comprising of 53 old 400w metal halide technology with 53 new 250W induction type highbay lighting. Induction lighting provides distinct advantages over the existing HID lamps, including extended lamp life and higher efficiency. Both these aspects make these lights ideal for the retrofit. The induction lighting used at the site is 250W but thanks to the efficiency of the technology, the light source emits similar levels to that of the 400W HID lamp.
