How does the 2-wire CCT function work?

This strip uses polarity to control color. Connecting positive/negative one way gives you 2700K warm white. Reversing the connections gives you 6500K daylight white. You need a specific controller or switch to do this.

What kind of controller do I need for this LED strip?

You need a controller designed for 2-wire CCT strips that can reverse polarity, or a simple DPDT (Double Pole, Double Throw) switch. A standard dimmer will not be able to change the color temperature.

Can I blend the colors to get 4000K?

No, this strip is designed to switch between 2700K and 6500K. It does not blend the two color temperatures. For blending, you would need a standard 3-wire tunable white LED strip.

Is this a 'Dim to Warm' LED strip?

No. While it provides warm white light, it does not automatically get warmer as you dim it. It is a CCT-tunable strip that switches between two fixed color temperatures.

What is the main advantage of COB technology?

The main benefit of COB (Chip-on-Board) is the creation of a completely seamless, dot-free line of light. It offers a more uniform and aesthetically pleasing look compared to traditional SMD LED strips.

How do I reconnect pieces after cutting?

You can use compatible 8mm 2-pin COB connectors to join cut sections without soldering. Ensure the connector is specifically designed for COB strips to make proper contact with the board.

Do I need an aluminum channel for this strip?

While not strictly required for all applications, using an aluminum channel is highly recommended. It acts as a heat sink to dissipate heat, which extends the lifespan of the LEDs and ensures consistent performance.

High-Density & Bright Output

A dense chip-on-board design ensures brilliant, consistent illumination at 12 watts per meter.

Versatile Project Options

Available in DC12V or DC24V, multiple lengths, and IP20, IP67, or IP68 ratings to fit any environment.

Simplified Installation

Compatible with standard 8mm 2-pin COB connectors, making connections quick and reliable.

A New Approach to Tunable White

This is not a standard dim-to-warm or blending CCT LED strip. It operates on a binary switching principle: Polarity A results in 2700K light, while reversing the polarity (Polarity B) results in 6500K light. This requires a controller capable of reversing polarity, such as a DPDT switch or a specialized 2-wire CCT controller.
The COB (Chip-on-Board) technology mounts LED chips directly onto the circuit board, creating a single, continuous light source. This eliminates the spotting effect seen with traditional SMD strips and improves thermal efficiency.

The dotless COB design provides perfect, even illumination on countertops without any distracting hot spots, making it an excellent warm led tape light for kitchens and workshops.

Architectural Cove & Accent Lighting Highlight architectural details with a flawless line of light. The ability to change the mood of a room from cozy to energetic with a simple switch makes this strip ideal for living rooms, bedrooms, and commercial spaces like restaurants and hotels.

Retail & Display Case Illumination Showcase products in their best light. Use the 6500K daylight setting for accurate color representation during business hours and switch to 2700K warm white to create an inviting atmosphere for evening shoppers. The wide 180° beam ensures every item is perfectly lit.

How to Install & Use This LED Strip

Clean the installation surface to ensure it is dry and free of dust and oils.
Measure and cut the strip at the designated cutting marks. For the 12V version, cut every 10mm; for the 24V version, cut every 20mm.
Peel back the adhesive tape and firmly press the strip onto the prepared surface. For best results, install in an aluminum channel for heat dissipation.
Connect the two wires to a compatible 2-wire CCT controller or a DPDT (Double Pole, Double Throw) switch. This is essential for reversing polarity to change the color temperature.
Connect the controller/switch to an appropriate DC12V or DC24V power supply, ensuring the voltage matches your strip.
Test the strip. One polarity should produce 2700K light, and reversing the polarity should produce 6500K light.

Power Consumption Reference

Calculate the total wattage for your project and choose a power supply that is at least 20% larger than the total load for optimal performance and longevity.
