Now more and more factories change to make LED lamps, but we are still insisting on special fluorescent lamps. The reason is that these special fluorescent lamps can not be replaced by LED lamps. The more important reason is that we have been devoting ourselves to develop and improve special fluorescent lamps for many years. As a result, our product performance is better than the other supplier's, such as higher UV irradiance and higher UV maintenance. These advantages ensure the long-term growth of our business.
