3, LED flashlight in addition to a fatal disadvantage of the color index is low! The color displayed under LED illumination is not true of incandescent light, which is to be analyzed from the spectral distribution, which belongs to the technical problem. There is also a disadvantage, the spot, due to the white light LED manufacturing process on the defect and with the reflector cup or lens with the error, easy to cause the yellow circle problem. Some manufacturers do not consider the quality of the device and with the problem, complete copy of the other products, the poor quality of the LED flashlight flooded the market, severely damaged the reputation of LED, in this very indignation, to Jiangsu and Zhejiang, Shenzhen as the most.
