Upgraded A21 30W Non-dimmable LED Bulb

Super Bright & Wider Beam Angle: SANSI 300W equiv. 5000 high lumen LED bulb, at about 166 lumen/watt output, with a wider 270-degree beam angle provides an all-around light distribution, can illuminate a larger place even the darker corners, provides you with excellent lighting experience! Flicker-Free: Adopting high light transmission optical lenses, up to 168 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 system 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.
