Upgraded A21 22W LED 3000K/5000K Light Bulb(US ONLY)

Features 1. BRIGHT AND EFFICIENT: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 3000 lumens using only 22 watts of power, equivalent to 200W incandescent bulbs. Based on 3 hours per day usage, save up to 90% electricity, annual estimated cost 2.65USD.2. FLICKER-FREE: Adopting high light transmission optical lenses, up to 120 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.3. 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.4.
