SANSI 250W Equivalent A21 LED Light Bulb, 4000 Lumens Dimmable LED Bulb with Ceramic Technology, 3000K Soft Warm E26 Base, 25,000-Hour Lifetime,

BRIGHT & EFFICIENT: This dimmable led light bulbs is the upgraded model.Compared with other, SANSI's highly efficient dimmable 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 90PCT electricity, annual estimated cost 2.95 DIMMABLE & 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. 0-100PCT smooth dimming, compatible with most TRIAC dimmers on the market(For smoother dimming, please select the appropriate dimmer). 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 & RELIABLE: The dimmable LED light bulbs 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.We also recommend using this bulb in a well-ventilated environment, away from a sealed lampshade, to effectively extend its lifespan SELECTABLE COLOR TEMPERATURE: This led light bulb offers two color temperature options: Warm 3000K provides soft, warm, and comfortable light, suitable for homes and cozy spaces. Daylight 5000K offers natural, near-sunlight light, suitable for living rooms, offices, schools, and other environments requiring higher brightness and more realistic lighting GUARANTEES: ETL listed, quality and safety verified, 25000-hour lifespan, 5 years warranty Long lifetime and 5 years warranty:
Long lifespan: 25000 hours VS 1000 hours ( for CFL bulbs)
5-Year Warranty: you can sure buy with confidence, any problems please feel free to contact us.

Notice:
This 250watt LED bulb only works with TRIAC dimmer. Zigbee and digital dimmers are incompatible for they may cause flicker or slight buzz when using.

SANSI Advantages--patented ceramic heat dissipation technology(CHDT)
Sansi Ceramic LEDs VS Aluminum LEDs
Dissipates heat more efficiently: Unlike other LEDs, whose chips must be molded on a PC board with a thermal adhesive, Sansi LEDs save this by molding chips directly on the ceramic. Fewer pieces mean better cooling efficiency, thus better heat dissipation.
More corrosive-resistant : ceramic deals with moisture and air pollution better than aluminum
