Two lighting modes - RGB Holiday Lighting and Daily Lighting. The lamp can be used as daily lighting while also creating atmosphere for celebrations or special occasions. Synchronization across multiple bulbs - A revolutionary feature ideal for environments with multiple fixtures such as fan lights, downlights, chandeliers, and more. When using the flash mode and smooth mode, the color-changing rhythm remains consistent across all bulbs. One remote control can operate all connected bulbs. High CRI RGBW - RGBW with high color rendering index, so colors appear more realistic to the naked eye. Memory function - The bulb remembers the last color and brightness when it is turned off, so there is no need to readjust each time you turn it on. Use scenarios - Living room or dining area with multiple fixtures: synchronize color across chandeliers and ceiling lights to create a cohesive ambience for movie nights or gatherings. - Holiday or party setups: use RGB Holiday Lighting to quickly transform the space with coordinated color effects across all bulbs. - Everyday tasks and activities: switch to Daily Lighting for accurate color rendering in kitchens, workspaces, or study areas without sacrificing mood.
