LEDs lights have many outstanding advantages such as high durability - not torn or broken filament ball; long life up to 50,000 hours; low power consumption, high luminous efficiency, and saving at 40-50% of power consumption. Compared with compact fluorescent light bulbs and fluorescent lamps, the LED lights are power-saving, and environmentally friendly because LED lights do not contain mercury or fluorescent powder coating.

With the introduction of Zero VND co-investment program, the Red Sun Energy JSC will replace all 1.2 m long fluorescent lamps in the workshops of Hai Nam Company at no cost. To get the investment return, the amount balance of power consumption between the two types of lights is calculated and paid to the Red Sun Energy JSC on a monthly basis until the initial investment value is duly paid off. Within 15 months, Hai Nam Company is bound to fully pay this invested amount.
