NFC ceiling light*W LED light source special LED light for power plant year, month day, this LED ceiling light adopts imported American light source, which is specially used for supplementing light in tunnels, subways, railways, etc. Technical parameters: Rated voltage (NFC/ON) -VAC/ VDC Hz Rated voltage (NFCA/ON) -VAC/ VDC Hz Light source LED Light source power×W Shell protection IP Anti-corrosion grade WF Overall dimensions××mm Total weight kg According to the national army Standard quality control system, after strict reliability and aging tests, the lamp failure rate is lower. Ultra-wide working voltage to ensure normal and stable lighting in harsh voltage fluctuation environments. The integrated aluminum alloy profile structure is light and has good impact resistance, and can work reliably and stably under vibration, impact and other environments. High-efficiency high-power LED light source, excellent light distribution design, with .% high-purity aluminum reflector and imported PC transparent parts with a light transmittance of up to %, the efficiency of the lamp is as high as %, which is more than% higher than the industry level. High-efficiency light source + high-efficiency light distribution + high-efficiency circuit makes NFC(A)/ON save more than% energy than the industry level. Reduce maintenance workload, continuous work for years without changing the light source, and the life span is nearly times that of fluorescent lamps. With reasonable circuit design and high-quality components, the electrical efficiency is as high as %, which is higher than the industry level by more than %.
