High efficiency 18W t8 led tube

S-Tube is an upgraded version CFL tube replacement with LED. It has the best configuration of brightness 
and power efficiency.

S-tube is designed to replace medium bi-pin T8 and T12 fluorescent tubes. S-tube fits directly into most 
fluorescent fixtures providing a simple upgrade to high quality LED lighting. S-tube is optimized to 
provide light outputs comparable to fluorescent and delivers the immediate benefits of white-LED lighting; 
long lifetimes, no maintenance, high efficency, no mercury, no recycling, no flickering, no buzzing, instant 
start, cold temperature operation, and high quality light. It provides energy savings of up to 75% over 
fluorescent applications that require long hours with low occupancy rates such as stairwells, corridors, 

warehouses, and remote locations. The high quality S-tube replacement tube is constructed from 
extruded aluminum to provide a virtually unbreakable, vandal proof lighting solution.

Why our S-tube?

Much longer life than CFL tube: min. 10 years (suppose that light is on 8 hours per day)
-70%~80% Energy-saving over Fluorescent tubes
-Solid State, high shock/vibration resistant
-Work without ballast, Instant soft-start
-No RF interference, No fickering or buzzing
-Quick and easy installation to minimize retrofit costs
-Minimum maintenance costs, Produce little Heat
-No Mercury and other hazardous materials, fully RoHS-compliant
-Continuous operation for white LEDs (10 years for other colors)
