Our 30W LED Tubular Lights have a wide voltage input, so local voltage fluctuations have no effect on the brightness and quality of the tube. The lamp tube is composed of a high-brightness LED light source, and the luminous efficiency per W is as high as 120 LM or more. Our LED Tubular Lights have three functions: open circuit protection, short circuit protection and over temperature protection. When the LED load has a short-circuit fault, the power supply will automatically stop outputting. After the fault is removed, the output program will be started automatically. In addition, when the temperature inside the tube is higher than 90 degrees, the precise constant current driving power supply will automatically reduce the current output, reducing the heat of the lamp, and ensuring the service life of the lamp without affecting the visibility of the illumination, so the performance of the whole process is stable. https://www.toppolighting.com/led-tubular-lights/
