The mercury is in a solid amalgam, easily recovered if the lamp is broken, or for recycling at end-of-life. These benefits offer a considerable cost savings of 35% to 55% in energy and maintenance costs for induction lamps compared to other types of lamps. In some applications, Magnetic Induction fixtures can provide energy savings as high as 75%. Features: Energy saving, free maintenance, saving more expenseon the same wattage than the traditional lamp. Application: Using for street lighting,tunnel lighting, garden lighting,court lighting, Floodlighting,etc...
