SANSI 350W Equivalent A19 LED Light Bulb, 5500 Lumens Bright Light Bulb, Non-Dimmable E26 5000K Daylight White LED Bulb, 22.5 Years Lifetime 40W Power Energy Saving Bulb for Home Workspace Classroom
[Bright and Efficient] SANSI's highly efficient light bulbs can provide 5500 lumens using only 40 watts of power, equivalent to 350W incandescent bulbs. Based on 3 hours per day usage, save up to 95 percent electricity, annual estimated cost 4.82 dollars.
[High Light Efficiency] Adopts self-encapsulated LED epistar, can provide high light efficiency 137 Lumens per Watt, meet your bright lighting needs in home, workspace, classroom and so on.
[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. (Note: For better heat dissipation we don't suggest you to use the bulb in an enclosed fixture.)
[Extented Lifespan] Uses Ceramic Plus Aluminum Compund Heat Dissipation. The temperature of the LED bulb made of ceramic material is very low when it is working, and its flame retardancy and heat resistance are better, it is not easy to cause the aging and yellowing of the lampshade, and it will look like new after long-term use, with better heat dissipation performance and longer service life. We also add aluminum heat sink to enlarge the heat dissipation effect.
[Guarantees] ETL listed, quality and safety verified, 22.5 years LED bulb lifespan, 5 years warranty.
