Hangzhou Riseen Lighting & Technology Co., Ltd. is a high-tech enterprise, engaged in R&D, manufacture and sales all kinds of LED high bay light . Since established in 2006, we holding the concept of "profession, innovation, honesty, service", pursuing excellency with advanced technology and sincere service.We devote ourselves to developing and applying LED high bay lights. We try our best to build up a first-class platform in led high bay light industry, which covers technology R&D, production and service, providing professional solutions of related LED lighting products for customers. At the same time, we have own excellent sales management team and pay attention to improvement of team skills and diathesis, cultivating a batch of excellent high-quality and specialization staffs. High quality products and high-efficiency team are able to meet different needs of international customers.Our high bay light has some core advantage:1. International leading space nanometer technology called MGCP is used to the radiator of lights with high stability, high reliability, high heat-sensitive; near-sonic speed design. Heat transfer is as high as 340m/s.2. We adopt UNICASE high temperature thermal fusion welding technology, Aluminum heat conducting cavity reaches a level without molecular leakage, can be long-term used (more than 10 years) without performance attenuation.3. Air convection design, all-round 3D uniform heat dissipation, temperature rise below 30 degrees, minous efficiency can be improved more than 20%.4. Safety: Integrative design of heat conduction and heat dissipation, there aren&＃39;t any risks of loss, corrosion and leakage. Inner cavity presents negative pressure in working state without the risk of expansion.5. Energy conservation: Instead of traditional air cooling and water cooling, it can avoid consuming secondary energy. It can be direct applied to heat dissipation of high power LED lighting which can save electric energy more than 65%.6. Environmental protection: There isn&＃39;t any harmful substance to let out not only in manufacturing process but also in using process. It conforms to EU RHGS standard. 7. 15 years lifetime and 5 years warranty.We have the CE UL DLC SAA CB TUV/CE CCC certificates for our led high bay lights, Riseen will become your best choice because of the most excellent quality, the most favorable price, and the in-time delivery.
