TeamSustain offers high quality imported LED luminary for commercial applications that suits the requirement without compromising on ambiance. LED lighting is becoming a viable alternative to conventional light source because of its overriding advantages long life, high efficiency, small size and short reaction time (no heating and high voltage).
The operational life of current white LED lamps is 50,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours.
With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labour expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs. These issues can all be virtually eliminated with the LED option due to negligible early failure rates and long operational life.
