What makes this CCT LED strip special compared to others?

Its primary advantages are the constant current design allowing a 20-meter run with no light loss, an ultra-high CRI of 97 for superior color rendering, and a high density of 180 LEDs/m for dotless illumination.

How do I control the color temperature and brightness?

You need a CCT (Correlated Color Temperature) LED controller. This strip has three input wires (+24V, WW for warm white, CW for cool white) that connect to the controller's output.

What size power supply do I need for a full 20-meter reel?

A 20-meter run consumes 360W (20m x 18W/m). We recommend a 24V power supply with at least 20% headroom, so a 450W or greater driver is ideal. See our power reference table for details.

Can I cut this LED strip to a custom length?

Yes, the strip can be cut at the designated cut marks, which are located every 12 LEDs (approximately every 66.67mm or 2.62 inches).

Is the black PCB just for looks?

While it provides a sleek, modern aesthetic, the black PCB is also practical for reducing light reflection and creating a more discreet installation, especially within dark-colored aluminum channels or fixtures.

What does a CRI of over 97 mean for my lighting project?

A CRI of 97 means the light source will render colors almost identically to natural daylight. This is crucial for applications where color accuracy is paramount, such as retail, art galleries, and photography.

Can I use the IP67 version outdoors?

Yes, the IP67 version has a silicone coating that makes it resistant to water splashes and dust, suitable for outdoor covered areas, patios, and bathrooms. However, it is not designed for permanent submersion in water (for that, you would need IP68).

This professional-grade CCT Dual White LED Strip delivers exceptional lighting control and color accuracy for demanding applications. Operating on DC24V, it features an ultra-high density of 180 2-in-1 SMD2835 LEDs per meter, producing an incredibly uniform, bright line of light. With a Color Rendering Index (CRI) exceeding 97, it renders colors with near-perfect fidelity.

The standout feature is its ultra long run design, allowing for single runs of up to 20 meters (65.6 feet) with almost no voltage drop, ensuring consistent brightness and color from end to end. Its narrow 8mm black PCB makes it ideal for discreet installations, especially for high-end backlighting, architectural coves, and retail displays.

Key Features
