SANSI 260-Watt Equivalent RGBW 4000lm Dimmable BR40 Mood Light Bulb

4000 Lumens super brightness SANSI RGBW light bulb has 3° color temperature: 2700k, 4000K and 5700k, color rendering index of up to 80 Ra, equivalent to 260 W incandescent bulbs, uses ceramic technology to improve the heat dissipation of the LED bulb and extends its lifespan to 25 ...4000 Lumens super brightness SANSI RGBW light bulb has 3° color temperature: 2700k, 4000K and 5700k, color rendering index of up to 80 Ra, equivalent to 260 W incandescent bulbs, uses ceramic technology to improve the heat dissipation of the LED bulb and extends its lifespan to 25,000 hours. Flash Mode, Fade Mode and Smooth Mode. You can adjust the light strobo speed by choicing different modes and set up the appropriate atmosphere to relax yourself.

The light brightness can also be adjusted to 25%, 50%, 75%, 100%. SANSI's ceramic 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 system 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.
