We are offering led corn light. 1) high efficiency: 4 watt corn light equivalent 30w general incandescent , 15w general energy-saving lamps 2) long life: light-emitting semiconductor chip no filament, no glass bulbs, not afraid of vibration, less breakable, life of up to 50, 000 hours (incandescent life of only 1000 hours, regular saving is only 8000 hours lamp life) 3)health: healthy light does not contain ultraviolet and infrared light, does not produce radiation (ordinary light contains ultraviolet and infrared ray) 4) green: no harmful elements such as mercury and xenon, which will help recovery, but does not produce electromagnetic interference (ordinary lamp contains mercury and lead, elements, energy-saving lamps in the electronic ballast will produce electromagnetic interference) 5) protection of eyesight: dc drive, no strobe (ordinary light are ac drive, will inevitably produce strobe) 6) light efficiency is high: fever small, 90% of the electrical energy into visible light (incandescent electric energy conversion 80% for the heat, only 20% of the energy into light energy) 7) high safety factor: the required voltage, current smaller, less heat, not produce security risk, in the mines and other dangerous places.
