A21 36W LED 3000K/5000K Light Bulb (US/CA ONLY)

Bright & Efficiency: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 5500 lumens using only 36 watts of power, equivalent to 650W incandescent bulbs. Based on 3 hours per day usage, save up to 95% electricity, annual estimated cost $3.94 Flicker-Free: Adopting high light transmission optical lenses, up to 18 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

What benefits can customers get from SANSI Patented Ceramic Technology? Potential major adverse effects of flicker identified in published research and/or Expert Opinion include these five factors:  Photoepilepsy or flashing-light induced seizure.  Stroboscopic effect and associated apparent slowing or stoppage of rotating machinery.  Migraine or severe paroxysmal headache often associated with nausea and visual disturbances.  Increased repetitive behavior among persons with autism.  Asthenopia, including eyestrain, fatigue, blurred vision, conventional headache, and decreased performance on sight-related tasks.
