Upgraded A21 18W LED Light Bulb (US ONLY)

Features:

• Bright & Efficient: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 2500 lumens using only 18 watts of power, equivalent to 150W incandescent bulbs. Based on 3 hours per day usage, save up to 87% electricity, annual estimated cost $2.16
• Flicker-Free: Adopting high light transmission optical lenses, up to 96 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.

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.
