Energy-saving device for fluorescent lighting

Light Eco Plus is a cost-effective, compact controller that delivers energy savings by controlling the amount of electricity that reaches a fluorescent lighting circuit. It is suitable for any space that uses fluorescent lighting such as offices, warehouses, shops and factories.

After fluorescent lights have been switched on and warmed up, they can operate effectively on a reduced power supply. The device works by allowing lights to turn on at standard utility voltage and then reducing the electricity supply to economy mode. The savings are easy to see using the LCD panel on the device, which clearly shows the savings being made; and the information is stored so that the saving history is available for download (using optional hardware and software).

The device is designed to sense a change in energy demand and switch back to mains voltage, when necessary. It is also designed to eliminate systems-wide failure, by bypassing to mains power if overload or low voltage is detected.

According to an example given by the company, if 20 fully loaded Light Eco Plus devices were installed in a factory with 1400 tubes operating for 20 hours a day, it would achieve: $15,000 saving on the annual electricity bill; equivalent to CO₂ reduction of 120 t; and a 100% return on investment in 12 months (based on an average kilowatt hour price of 10c).

Designed for retrofitting, it can be easily and quickly installed into existing fluorescent lighting circuits, by an electrician. Once installed, there are no ongoing costs. Models from 2.4 to 4.8 kVA are standard; however, larger models are available on request.
