The 2835-120-4mm-12V-WHITE uses horizontally mounted SMD 2835 LEDs on the PCB. With 120 LEDs/m SMD 2835 LEDs on a 4mm PCB and 12V constant-voltage input, it is well-suited to cabinet, display, furniture, and architectural accent lighting, available in 2200K, 2700K, 3000K, 3500K, 4000K, 5000K, 6500K.
Why Choose These LED Strip Lights?
- Horizontal-mount LED layout: The SMD 2835 LEDs are mounted across the width of the 4mm PCB and emit light from the top surface.
- 4mm ultra-narrow PCB: The 4mm board fits micro-channels and narrow extrusion channels where wider strips cannot fit.
- 120 LEDs/m LED density: 120 LEDs/m provides even illumination along the strip with reduced visible hot spots.
- 12V constant-voltage input: Standard 12V DC constant-voltage operation with compatible drivers and dimmers.
- CRI 80 / 90 / 97 colour rendering: Accurate CRI for retail, display, and architectural applications where colour quality matters.
- IP20 or IP67 options: Open PCB for dry interiors; encapsulated option available for damp environments.
- Certified & compliant: UL Listed, CE, RoHS, CB, UKCA, PSE, and ErP compliance marks for professional projects.
- Custom project supply: Custom CCT, length, connectors, adhesive, and packaging available for project quantities.
