Potential major adverse effects of flicker identified in published research and/or
Expert Opinion includes 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 is 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.
What Colour Temperature Should I Choose?
💡Bright & Efficient: Compared with other LED bulbs, SANSI's highly efficient E26 light bulbs
can provide 900 lumens using only 9 watts of power, equivalent to 60W incandescent bulbs.
Based on 3 hours per day usage, save up to 87% electricity, annual estimated cost $1.
💡 Patented Ceramic technology: SANSI's patented technology replaces the traditional Mcpcb
the 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.
💡 Flicker-Free: Adopting high light transmission optical lenses, up to 17 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.
💡 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.
