Tunable COB LED Strip

Product Description

When you need one strip to shift from warm evening light to bright cool working light, this tunable CSP board does it without the two-color dotted look of older tunable strips. The 10mm flip-chip COB carries 640 LEDs/m split into warm and cool channels (18W + 18W/m) on 12V DC, blending smoothly from 2700K to 6000K with CRI above 90.

Why a flip-chip CSP tunable strip

Conventional tunable-white strips place warm and cool SMDs side by side, so at mixed settings you can pick out alternating dots and the color looks uneven. This board uses flip-chip CSP devices at high density under a continuous emitting surface, so the two channels blend into one uniform line at every color temperature in between. That matters in hospitality and homes, where the same space has to go from a warm dinner setting to a bright cleanup mode.

Key Features

• Smooth tunable white from 2700K to 6000K
• 640 LEDs/m flip-chip CSP — uniform, no alternating warm/cool dots
• Dual channels, 18W + 18W/m on 12V DC
• CRI >90 across the range
• 10mm PCB, extruded protective structure
• Works with standard CCT (CW/WW) controllers and dimmers

Typical Applications

• Hotel rooms, restaurants, and circadian residential lighting
• Offices and meeting rooms that switch between focus and relaxed scenes
• Smart-home and DALI/KNX integrated projects
• High-end retail where color temperature tracks the display

Specifications

Installation notes

1. Use a dual-white (CCT) controller — it has two outputs plus common, not a single-channel dimmer.
2. Because it's 12V, inject power every 5m and size the driver for the combined 36W/m peak.
3. Wire warm and cool channels to the correct outputs or the temperature response will be reversed.
4. Mount in an aluminum profile to protect the dense board and extend its life.

Frequently Asked Questions

Will I see separate warm and cool dots?

No — the 640-LED flip-chip array sits under a continuous emitting surface, so mixed settings read as one even line rather than alternating dots.

What controller do I need?

Any CCT/tunable-white controller with common-plus-warm-plus-cool outputs for 12V constant-voltage strips. Match its amperage to the run length at 36W/m peak.

Why 12V and not 24V?

This version is built at 12V for compatibility with common low-voltage smart systems. Keep runs to 5m per feed to limit voltage drop.

Can I order custom specifications or OEM branding?

Yes. As the manufacturer we support custom lengths, colour temperature, CRI, packaging and OEM labeling; send us your specification.

Can I request a sample before a bulk order?

Yes, samples are available so you can confirm the colour, build and output before a bulk order. Request a sample through our contact page.
