 SANSI Advantages--patented ceramic heat dissipation technology(CHDT)
 Sansi Ceramic LEDs VS Aluminum LEDs
 Dissipates heat more efficiently: Unlike other LEDs, whose chips must be molded on a PC board with a thermal adhesive, Sansi LEDs save this by molding chips directly on the ceramic. Fewer pieces mean better cooling efficiency, thus better heat dissipation.
 More corrosive-resistant: ceramic deals with moisture and air pollution better than aluminum

 About SANSI
 SANSI was founded in 1993 in Shanghai, the idea of a retired director of Research Institute. He is dedicated to the High Technology of LED applications. Now SANSI has been a Global Leader in LED lighting and displays with over 400 R&D engineers, 2000 employees, and three advanced factories. Highest resolution screen in New York Square and in Verizon Center, Washington, D.C. made by SANSI.

Bright & Efficient: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 4000 lumens using only 27 watts of power, equivalent to 250W incandescent bulbs. Based on 3 hours per day usage, save up to 87% electricity, annual estimated cost $2.95.
Flicker-Free: Adopting high light transmission optical lenses, up to 156 LED chips can not only provide you and your family with the light source they need daily but also provide a healthy living or work environment. No flickering, no noise.
Patented Ceramic technology: SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chip on the ceramic heat sink, effectively reducing the systematic thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making SANSI's bulbs perform with higher light efficiency.
Safe and Reliable: The lamp body is made of special ceramic material, and the flame retardant grade reaches grade V0; the reinforced insulation structure means no risk of electric shock, its safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and durable; The hollow design is good for heat dissipation.
Guarantees: ETL listed, quality and safety verified, 22.5 years LED bulb lifespan, 5 years warranty.
