Features of Semi-Circular Neon LED Strip
1. 180° Wide Beam with a Semi-Circular Profile
A 15x13mm semi-circular profile spreads light across a wide 180-degree beam, creating a smooth glow with minimal visible spotting. This rounded surface suits projects that need a soft edge rather than a narrow beam, including contour lines, decorative details and illuminated architectural features. It works well for visible edge accents indoors.
2. 120 SMD2835 LEDs per Meter
With 120 SMD2835 LEDs per meter and a 5 m standard roll, the strip provides closely spaced light sources for an even neon effect. The 7.2W/m constant-voltage design is available in 12V and 24V versions, helping buyers match the strip with different low-voltage power layouts and wiring plans. The two voltage options simplify project planning.
3. Flexible Silicone Body for Gentle Curves
The flexible silicone body can follow gentle curves around walls, ceilings, cabinets or display structures. Its soft construction makes installation easier on prepared surfaces while retaining the semi-circular profile that gives the finished light line its rounded appearance. It suits spaces where rigid fixtures are hard to place when needed.
4. Anti-Yellowing Silicone with IP65 Protection
Silicone material with anti-yellowing and high-temperature resistance supports stable use in demanding lighting environments. IP65 protection and a working temperature range of -25°C to +60°C make the strip suitable for selected semi-outdoor installations when power connections, cut ends and seals are protected. Assess the full installation method.

Semi-Circular Neon LED Strip Wiring Diagram & Installation Guide

Installation Steps for Semi-Circular Neon LED Strip

1. Mark the Required Length
Lay the semi-circular Neon LED Strip along the intended route and determine the required length. Remove the excess section only at the printed scissor mark to avoid damaging the internal circuit.
2. Solder the Wires and Prepare the First End
Connect the red wire to the positive terminal and the black wire to the negative terminal on the PCB. After soldering, apply suitable sealant around the open end of the strip before fitting the end cap in the indicated direction.
3. Close the Opposite End
Apply an even layer of sealant to the remaining open end. Slide the end cap onto the strip in the direction shown in the installation guide, making sure the cap is seated firmly and the opening is properly covered.
4. Install the Mounting Clips
Position the fixing clips along the planned installation path. Keep the spacing suitable for the shape of the light line, then tighten the screws with a screwdriver so that each clip remains stable on the mounting surface.
5. Seat the Strip in the Clips
Place the light-emitting surface upward and press the silicone strip into each mounting clip from above. Check that the strip is fully engaged and that its surface remains parallel with the upper edge of the clips.
6. Complete the Electrical Protection
Connect the installed strip to the compatible constant-voltage power supply. Before energizing the circuit, insulate the terminals and protect the joints and end caps against short circuits, moisture entry and corrosion.
Precautions for Semi-Circular Neon LED Strip

1. Avoid Lateral Bending
Do not force the semi-circular Neon LED Strip to bend sideways. Lateral deformation can place stress on the internal PCB and may affect the profile, connection or light output.
2. Keep the Strip Free from Twisting
Install the strip in a flat, aligned position and do not twist its silicone body. Twisting may distort the semi-circular profile and prevent the strip from sitting correctly inside the fixing clips.
3. Maintain a Minimum 50 mm Bending Diameter
Do not wrap the strip around objects with a diameter smaller than 50 mm. A sufficiently large bending diameter helps reduce mechanical stress and preserves the shape of the silicone housing during installation.
Recommended Applications for Semi-Circular Neon LED Strip
1. Architectural Contour and Cove Lighting
The broad 180° output makes this neon LED strip useful for architectural contour work along walls, ceilings, columns and built-in details. Its semi-circular profile produces a soft continuous line for cove edges, recessed features and decorative structures where the light needs to spread across the visible surface. It supports layered light plans.
2. Hotels, Restaurants and Entertainment Interiors
For hotels, restaurants, bars and entertainment interiors, the flexible strip adds a refined glow to ceiling borders, counters, feature walls and decorative structures. Warm white, neutral white and pure white versions let designers coordinate the lighting mood, while the silicone body follows curves without the rigid look of aluminum fixtures.
3. Cabinet, Shelf and Display Accent Lighting
In homes, offices, retail areas and display spaces, use the neon LED strip around cabinets, shelves, showcases and furniture edges. The 15x13mm semi-circular shape provides a visible rounded light line for accent and auxiliary lighting, helping highlight selected surfaces without requiring a bulky linear lamp or exposed point-light source.
4. Suitable Semi-Outdoor Decorative Details
