Yingsheng Energy-saving Technology Co. Ltd is a high-tech enterprise specializing in R&D, production and sales of energy-saving products, as well as energy-saving technical services. Our leading product, also a patented product, Fluorescent Tube With a Thermal Sleeve-type (YSG Energy-saving Fluorescent Tube), is a new-type, eco-friendly light tube that reduces energy consumption by up to 53% compared to traditional T8 fluorescent tube. It may directly replace T8 fluorescent tubes without having to change circuit or doing any rewiring. Key features of YSG Energy-saving Fluorescent Tube: Energy Efficiency: Compared to the traditional T8 fluorescent tube, a YSG Energy-saving Fluorescent Tube can reduce energy consumption by 48%-53% with a 20%-40% increase in brightness. Long Life Span: Between 12, 000 and 16, 000 hours, 2.5 times as long as the traditional T8 fluorescent tube. High Color Rendering: Above Ra:87, soft light with no flickering, preventing light pollution and care of eyes. Low Heat: working less than 40℃(104℉) constantly low temperature, which lowers ambient temperature. Advanced Technology: An environment-friendly light tube that prevents mercury pollution, tube-end blackening and lumen depreciation. The product is CCC, CE, RoHS and IEC certified and it fully conforms to standard of LVD and EMC. We look forward to building a mutually beneficial business relationship with customers worldwide and make the world a greener place.
