Description:

Bright & Efficient: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 4000 lumens using only 27 watts of power, equivalent to 250W incandescent bulbs. Based on 3 hours per day usage, save up to 90% electricity, annual estimated cost $2.41.

Flicker-Free: Adopting high light transmission optical lenses, up to 156 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 long-lasting ; The hollow design is good for heat dissipation.

Guarantees: ETL listed, quality and safety verified, 22.5 years LED bulb lifespan, 5 years warranty.

Tips:
SANSI LED bulb is hotter than others, because we have adopted patented heat dissipation technology.

Our LED bulbs are designed to dissipate all the heat emitted by the LED chips to make sure that the chips won’t be hot when working. Unlike other brands in the market, whose LED bulbs cannot achieve the driver disassociation like our company did, the lifespan of the LED chips will be greatly shortened as the heat is not able to be dissipated.

In a word, the heat is all transferred to the ceramic body so as to prolong the lifespan of our bulbs. Rest assured that it is normal and we suggest not touching them with bare hands when working.
