SANSI A21 Led Light Bulb 5000k 4 Pack, 250W Equivalent + 200W Equivalent, 4000 Lumens + 3000 Lumens

• Package: Led light bulb 4 pack, (27W 2 pack + 22W 2 pack).
• 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 & 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; The hollow design is good for heat dissipation.
• Guarantees: ETL listed, quality and safety verified, 22.5 years LED bulb lifespan.
