COB LED Strip Lights | Smooth, Dot-Free LED Strip

COB LED strip lights deliver a smooth, dot-free line of light, making them ideal for applications where uniform illumination and a clean, professional finish are essential.

Using Chip On Board (COB) technology, the LEDs are densely packed directly onto the strip, producing continuous illumination with no visible spotting. This makes COB LED strip particularly well suited to signage, architectural features, display lighting, shelving and installations where the strip is visible or mounted close to the surface.

COB LED strip is available in single colour and tuneable white (CCT) options and typically runs on 12V or 24V constant-voltage systems. It can be dimmed when paired with a compatible driver and control method, allowing you to adjust brightness and ambience to suit the space. For longer runs and reduced voltage drop, 24V COB LED strip is often preferred.

To complete your installation, COB LED strip should be matched with an appropriate LED driver and, where dimming or control is required, LED controllers or dimmers. Allowing sufficient capacity on both the driver and controller helps ensure stable performance and long service life.

Frequently Asked Questions

What are COB LED strip lights?

COB LED strip lights use Chip-on-Board technology to create a smooth, dot-free line of light. They are ideal for kitchens, signage, retail displays and visible installations.

Are COB LED strips brighter than standard LED strips?

COB strips are often brighter and produce a more uniform glow due to their high LED density. They also offer improved colour rendering for premium lighting projects.

Do COB LED strips come in 12V and 24V options?

Yes. 12V COB strips are easier to cut and perfect for short runs, while 24V COB strips are better for long, continuous lengths with reduced voltage drop.

Can I cut and reconnect COB LED strips?

Yes. COB strips have cut points and can be reconnected using solder or compatible LED strip connectors. For guidance, see our Cutting, Connecting & Installing LED Strips guide.

Where can I use COB LED strip lights?

COB strips are ideal for kitchens, ceilings, shelving, display cases, photography setups, signage and any project that requires a clean, dot-free finish.

What power supply do COB LED strips need?

COB LED strips must be paired with a suitable LED power supply that matches the strip voltage and wattage. Use our voltage guide to help you choose the correct option.

When should you choose COB LED strip?

COB LED strip is best suited to applications where a continuous, dot-free line of light is required. Because the LEDs are densely packed along the strip, COB technology eliminates the visible spotting often seen with standard LED strip, especially when installed close to the surface or without a diffuser.

Application	Why COB LED Strip Works Well
Signage & lettering	Produces smooth backlighting in shallow returns with no visible LED dots
Architectural features	Creates clean, continuous light lines for modern detailing
Shelving & displays	Even illumination without glare or visible light points
Under-cabinet lighting	Uniform task lighting with a clean finish

Choosing voltage, brightness and colour

COB LED strip is commonly available in 12V and 24V options. For longer runs and improved voltage stability, 24V is typically recommended. Brightness is determined by wattage per metre, allowing you to choose anything from subtle accent lighting to high-output feature illumination. Colour options include fixed single colour temperatures and tuneable white (CCT) for adjustable ambience.

Dimming and system compatibility

COB LED strip can be dimmed when used with compatible constant-voltage drivers and controllers. To ensure reliable performance, always match the voltage across the system and allow sufficient headroom on both the power supply and controller to prevent overloading.

COB LED strip vs standard LED strip

Compared to standard SMD LED strip, COB LED strip prioritises visual smoothness over point brightness. If the strip will be visible or installed close to the surface, COB is usually the better choice. For applications where maximum brightness or longer viewing distance is required, standard LED strip may be more suitable.

Our COB LED strip lights are stocked in the UK and trusted by sign makers, installers and designers who need consistent, professional lighting with a flawless finish.
