LED flat lamp features and advantages: LED panel light appearance,Website: , simple and generous, no harmful substances, energy saving and environmental protection, DC work, protect the eyes, long life. Advantages: voltage: LED using low-voltage power supply, a single voltage between 1.9-4V, more secure than the use of high voltage power supply. Efficiency: high efficiency, at present, the highest efficiency of the laboratory has reached 161 lm/w (Cree), is the most efficient lighting products. Seismic resistance: LED is a solid state light source, because of its particularity.
