SANSI: Providing a Healthier, Safer, and More Reliable Light Source through Scientific Design

Since its founding in 1993, SANSI has been dedicated to technological innovation in a wide range of LED lighting. With over 500 R&D engineers, 2,000 employees, and three advanced factories, the company has fully integrated product design, production, sales, and installation, reaching over 40 nations on five continents and continuing to grow.

The SANSI LED Lighting Series offers a range of high-quality bulbs that outperform traditional options in both efficiency and performance.

BRIGHT AND EFFICIENT: SANSI's highly efficient LED bulbs can provide up to 4,000 lumens using only 27 watts of power, equivalent to a 250-watt incandescent bulb. This translates to a staggering 87% electricity savings, with an estimated annual cost of just $3.25 based on 3 hours of daily usage.

FLICKER-FREE: Adopting high light transmission optical lenses, SANSI's bulbs feature up to 144 LED chips, providing a light source that meets the daily needs of your home or workspace while maintaining a healthy, comfortable environment. With no flickering or noise, these bulbs offer a superior lighting experience.

PATENTED CERAMIC TECHNOLOGY: SANSI's innovative technology replaces the traditional aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chips onto the ceramic surface. This significantly reduces the thermal resistance between the LED PN junction and the heat sink, resulting in faster heat conduction and higher product reliability, ensuring superior light efficiency.

SAFE AND RELIABLE: Constructed with a special ceramic material, the lamp body is highly flame-retardant, meeting the V0 safety standard. The reinforced insulation structure eliminates the risk of electric shock, while the WF2 anti-corrosion grade shell material ensures long-lasting durability and reliability. The hollow design further enhances heat dissipation, contributing to the overall safety and performance of SANSI's LED bulbs.

GUARANTEED QUALITY: SANSI's LED bulbs are ETL listed, with their quality and safety verified. These bulbs boast an impressive 22.5-year lifespan, providing long-lasting and dependable illumination.

MULTIPLE USAGE & WIDE APPLICATIONS: SANSI's LED Light Series offers a variety of bulb options to meet your diverse lighting needs, including 9W, 22W, and 40W models in both 3,000K and 5,000K color temperatures, with brightness ranging from 900 to 6,000 lumens. These bulbs are suitable for a wide range of applications, from residential to commercial settings.

SANSI's commitment to scientific design and technological innovation has resulted in a line of LED bulbs that not only provide a healthier, safer, and more reliable light source but also deliver significant energy savings and long-lasting performance. Experience the difference with SANSI's LED Lighting Series.
