SANSI A21 LED Light Bulbs, 4-Pack, 250W + 200W Equivalent, 4000/3000 Lumens

LED Light Bulb 4 Pack

Flicker-Free Lighting

Adopting high-quality optical lenses, our 4-pack LED light bulbs incorporate up to 156 LED chips. Not only do they provide daily lighting essentials, but they also create a healthy living and working environment. No flickering and no noise, ensuring a pleasant and uninterrupted experience.

Patented Ceramic Technology

With SANSI's patented ceramic technology, the traditional aluminum substrate is replaced by a non-conductive ceramic heat sink. This innovative design directly solders the LED chips onto the ceramic substrate, significantly reducing thermal resistance and enhancing heat dissipation for higher light efficiency.

Safe and Reliable Design

Our lamp body is made of special ceramic material, achieving a flame retardant grade of V0, which minimizes fire risk. The reinforced insulation structure prevents electrical shock, while the shell material, reaching the WF2 anti-corrosion grade, ensures durability. The hollow design promotes efficient heat dissipation.

Quality and Safety Assured

ETL listed, our bulbs are rigorously tested for quality and safety. Enjoy a lifespan of up to 22.5 years, providing exceptional value and peace of mind.

These features combine to make our LED light bulbs a smart choice for upgrading your lighting needs.
