Improved anti-glare design Our premium series linear lights are equipped with an anti-glare baffle and honeycomb optical lenses, effectively reducing glare and providing a comfortable lighting environment for your eyes. Up and down light Our specially designed linear lights now feature an uplighting function that effectively brightens up your ceiling, reducing the contrast in brightness within the room. The upper light emitted is intentionally softer and less intense than the downlight, ensuring a more comfortable lighting experience for your eyes. 3000K/4000K/5000K Selectable Our linear lights offer the flexibility of choosing between three different color temperatures - 3000K, 4000K, and 5000K. With the convenient CCT switch button, you can easily switch between warm light, natural light, and cool light.
