Key Features of 400LED Side Emitting COB LED Strip Light
1. Side-Emitting Design for Hidden Light Source Effects
This strip emits light from the side, so it is easier to keep the LED source hidden while still getting a clean lighting line. That makes it a very practical choice for edge lighting, cabinet edges and other places where you want the light to show, but not the strip itself.
2. 10mm Cut Unit for Flexible Project Work
The strip can be cut every 10mm, which gives you a lot of freedom when working on short runs, small details or custom shapes. This is useful for projects that need more precise fitting without wasting material.
3. 5V Low-Voltage Design for Small Indoor Projects
Because it runs on 5V DC, this model is a good fit for smaller indoor lighting setups, low-voltage systems and projects where safety and simple wiring matter more than high power output.
4. 5mm Narrow PCB for Compact Lighting Designs
With a slim 5mm PCB, this side-emitting COB strip fits easily into narrow channels, tight installation spaces and compact lighting structures. The narrow width makes it a practical choice for decorative lighting details, display edges, furniture lighting and other applications where installation space is limited.

Recommended Applications for 400LED Side Emitting COB LED Strip Light
1. Edge Lighting
This is the main use case for the strip. The side-emitting structure helps the light travel along the edge, which is useful when you want a clean line of light around panels, shelves or structural details.
2. Backlit Letters
It also works well for backlit letters, especially when the light source needs to sit inside a narrow space and shine sideways instead of straight up. That makes the finished letters look cleaner and more even.
3. Car, Motorcycle and Game Room Accent Lighting
It is a good fit for car atmosphere lights, motorcycle decoration, game rooms and amusement-style projects where a slim side-emitting strip can create a stylish accent effect.
