How does light eco work?
Fluorescent and HID lights are normally operated within the standard utility
supply voltage. The normal supply voltage is only required to allow the lights
to strike. Thereafter the operating voltage can be reduced, still within the
range of the Power Utility, with only a small reduction in light output.
When a bank or strip of lights is turned ON, Light Eco holds the voltage at
normal for a preset time and then switches to economy mode.
LIGHT ECO uses an autotransformer to switch from normal to economy voltage.
After a start up period of 3 to 5 minutes, the autotransformer switches to
the reduced voltage. The drop in current is dependent on the age and type
of fluorescent fittings. Cases documented show consistent savings in excess
of 25% to 35%.
Has light eco been proven?
More than 45,000 Light Eco units have been installed in a wide range of sites
including schools, supermarkets, banks, industrial workshops, apparel factories,
hotels, hospitals, office blocks and car park buildings. Service Stations and
warehouses are also prime locations for Light Eco. In the Philippines, experience
has shown that six Light Eco units installed in a condominium carpark where 220
tubes are turned ON for 24 hours a day will save P250,000.00 on the annual electricity
account, with a Return on Investment of 111%, and payback in 10.8 months.
The savings is based on an average kilowatt-hour price of P5.78 per KwHr.
The rising cost of electricity means that many companies and organizations
are now paying more than this rate per kilowatt hour meaning Light Eco gives
highly effective returns on investment.
