Know before you buy
COB (Chip on Board) technology allows the LEDs to be densely packed together, creating a continuous, seamless line of light. Unlike traditional LED strips, this eliminates visible 'hot spots' or dots, providing a smooth glow even when the strip is visible.
No, this is a component-based system. You will need to purchase a compatible 24V power supply and an RGB+Tunable White controller separately to operate the lights.
Yes, the strip is designed to be cut to size. You can trim it at the designated cut marks to achieve the exact length needed for your installation.
This strip has an IP20 rating, meaning it is for indoor use only and is not protected against moisture or water. It is ideal for dry areas like under-cabinet lighting or accent lighting in living rooms and bedrooms, but it should not be installed in bathrooms or near sinks.
The tunable white feature allows you to adjust the color temperature between 2700K (a warm, cozy yellow-white) and 5000K (a crisp, cool daylight white). You will need a compatible controller to adjust these settings to match your preference or the time of day.
The strip comes with a 3M adhesive backing for a simple peel-and-stick application. For a more secure or permanent installation, especially on textured surfaces, we recommend using additional support clips.
