About this item

• SANSI: The Upgrade 300 Watt LED Light Bulbs provide more rounded looks and enhanced performance, free E26 to E39 adapter can fit different bases.
• LET THERE BE LIGHT!: 5500lm output and 5000K daylight make this light bulb perfect for warehouse, basement, barn, garden, shopping mall, supermarket, workshop, display area etc. Outdoor with protected fixtures or indoor, any place where bright light is needed, and you don't have to worry about the energy bills that high lumen LED bulbs bring to you.
• SUPER BRIGHT, HIGH EFFICIENCY: Usually the brightness of light is measured by power, but actually measured by lumen, the 40w daylight light bulb is 5500lm and divided by 40w to give 137.5 lm∙w−1 luminous efficiency, out-perform others! Plus, 25,000 hour lifetime saves your replacement costs.
• FLICKER FREE: LED bulbs might be flickering due to loose or incorrect wiring, a sudden drop in home voltage, incompatible dimmer, or bulb components such as a defective LED driver. But SANSI won't flicker for the last reason, a better power supply will have constant current drivers installed that stabilize the current to the LED by varying voltage, this ensures constant brightness, and SANSI LEDs have drivers installed on the chip inside.
• INNOVATIVE CERAMIC TECHNOLOGY: Our approach involves bonding the LED chip to the ceramic heat sink, enhancing heat dissipation and improving reliability. It is widely recognized that ceramic heat sinks are eco-friendly materials that offer excellent insulation, superior thermal conductivity, resistance to electrical leaks, durability under high temperatures, and silent operation, among other benefits. Space constraints limit further elaboration.
