SANSI 400W Equivalent A21 LED Light Bulb, 3000K Warm White SANSI 200W Equivalent A19 LED Light Bulb, 3000K Warm White

Highly Efficient and Comfortable LED Bulbs

Power Efficiency: Compared to other LED bulbs, SANSI's bulbs provide 3000 lumens using only 20 watts of power, equivalent to 200W incandescent bulbs. This translates to savings up to 90% on electricity when used for 3 hours per day. The annual estimated cost is just $2.41, making SANSI bulbs a cost-effective choice.

Flicker-Free Lighting

Optical Quality: SANSI bulbs adopt high-light-transmission optical lenses, ensuring both a bright and healthy light source. With up to 135 LED chips, these bulbs offer a steady and consistent light, eliminating flickering and noise. This means a more comfortable and healthier living and working environment for you and your family.

Patented Ceramic Technology

Heat Dissipation: SANSI's patented ceramic technology replaces the traditional aluminum substrate with a non-conductive ceramic heat sink. This innovation directly soldered the LED chip onto the ceramic heat sink, effectively reducing thermal resistance and enhancing light efficiency. This results in faster heat conduction and higher product reliability.

Safe and Durable Design

Material Quality: The lamp body is made of special ceramic material, making it flame retardant with a grade of V0. The reinforced insulation structure guarantees no electric shock risks, and the whole shell material reaches the WF2 anti-corrosion grade, ensuring durability and reliability. The hollow design further enhances heat dissipation, contributing to the bulb's longevity.

Reliability and Quality Assurance

Durability and Certifications: SANSI products are ETL listed, ensuring quality and safety verification. With a 22.5-year LED bulb lifespan, you can trust that your investment will last for years to come, providing consistent performance and saving you money on replacements.
