What Is a COB Linear Light? Types, Applications, and Selection Factors
A COB linear light is a linear lighting solution built around COB, or “chip-on-board,” LED technology. Multiple LED chips are mounted closely together on a circuit substrate, creating a visually continuous illuminated line rather than the distinct points often seen with spaced LEDs. The term can refer to a COB LED strip used inside a channel or to a complete linear fixture incorporating COB technology, so buyers should confirm exactly which product a supplier is quoting.

COB linear lights are used for architectural details, joinery, display lighting, and other indoor applications where a smooth line of light is desirable. The right choice depends on more than appearance: output, color quality, operating voltage, heat management, installation profile, and control requirements all affect suitability. Below, we explain the main types and applications and provide a practical checklist for evaluating options with a supplier such as ENTA Lighting.
Summary: The Main Points
- A COB linear light uses closely arranged LED chips to produce a continuous-looking luminous line.
- It may be supplied as a flexible strip, a rigid or integrated linear fixture, or a strip installed in a channel.
- Choose based on the required lighting effect, measured output, color quality, voltage, installation conditions, and thermal design.
- Confirm the complete system—not only the strip—including driver, control method, profile, and installation details.
How COB Linear Lighting Works
COB technology and the continuous-line effect
In a COB LED assembly, LED chips are mounted closely together on a substrate and covered by a phosphor layer. When powered, the closely spaced chips appear as a more continuous band of light than a conventional strip with visibly separated emitters. The result depends on the specific product and installation; a cover, viewing distance, surface finish, and dimming level can all affect what the eye sees.
“COB linear light” is not a single standardized fixture format. One supplier may use the term for a flexible COB strip, while another may use it for a complete luminaire with a housing, diffuser, driver, and mounting hardware. For accurate comparisons, ask for the product construction, optical components, and included accessories.
What the system does
A COB linear system can provide accent, task, or general supplementary lighting, depending on its output, placement, and optics. It can follow a straight run or, when the selected strip and installation allow, a curved detail. The substrate, profile, and mounting surface influence how well the product can be installed and how heat is managed.
Types of COB Linear Lights
Flexible COB LED strips
Flexible strips are suited to applications where the light needs to fit a narrow channel, cabinet detail, or other shaped recess. Their flexibility does not mean they can bend in every direction or around any radius; the product’s bend limits and installation instructions should be checked before specifying it. A suitable aluminum profile can provide a mounting surface and help conduct heat away from the strip.
Rigid or integrated linear fixtures
Rigid boards and complete linear fixtures offer a defined shape and mounting format. They may be easier to specify for a straight run or repeat installation where consistent dimensions and a finished housing are important. Check whether the driver, diffuser, connectors, end caps, and mounting hardware are included or need to be sourced separately.
Surface-mounted, recessed, and concealed systems
A COB strip can be installed in a surface-mounted, recessed, or concealed profile, depending on the architecture and product design. A diffuser may soften the appearance or provide additional protection, but it can also change the amount and distribution of light. Review the assembled system rather than assuming that the strip alone will deliver the desired visual result.
Applications and Limitations
Common indoor uses include under-cabinet lighting, shelving, wardrobes, reception details, display cases, coves, and architectural reveals. COB’s continuous-looking output can be valuable where a visible dotted pattern would distract from a clean linear detail. For a primary task area, however, specify the actual light level and distribution needed instead of selecting by appearance alone.

COB is not automatically the best option for every installation. Long runs can require attention to voltage drop, feed points, and wiring layout, while enclosed or poorly ventilated spaces may make thermal design especially important. In damp, dusty, or exterior-facing locations, verify the complete assembly’s protection rating and installation suitability rather than relying on a strip description in isolation.
Key Specifications to Compare
Product specifications vary, so the figures below are examples for discussing a design—not universal COB product standards. A project brief might compare a 24 V DC system, a 10 W/m strip, and a target output of 900 lm/m. Those values must be confirmed against the selected product’s datasheet, and output may differ after adding a profile, diffuser, or other optical components.
| Specification | What to check | Why it matters |
|---|---|---|
| Light output and power | Lumens per meter and watts per meter | Helps assess brightness and power requirements for the intended use. |
| Color quality | Color temperature and CRI | Influences the appearance of materials and the character of a space. |
| Electrical details | Voltage, driver compatibility, and run length | Supports a suitable power and wiring plan. |
| Physical format | Width, cut intervals, bend limits, and profile fit | Determines whether the product can fit the installation detail. |
| Environmental suitability | Protection rating and installation conditions | Helps confirm whether the complete assembly suits the location. |
How to Select a COB Linear Light
Start with the lighting purpose
Decide whether the line is for accent, display, task, or supplementary ambient lighting. Then define the desired visual effect, mounting position, approximate run length, and whether the light source will be directly visible. These choices guide the required output, color, profile, and optical treatment.
Check the complete electrical and thermal system
Match the strip voltage to a compatible driver and confirm the driver’s capacity for the connected load. Ask the supplier how the product should be installed, whether the run needs power feeds at more than one point, and what profile or mounting surface is recommended. Do not assume that a higher wattage per meter automatically produces a better result; the application, heat management, and target output should be considered together.
Confirm color, controls, and installation details
Specify the preferred color temperature and required color-rendering performance, particularly where products, food, fabrics, or finishes must be presented consistently. Confirm whether the project needs dimming and identify the intended control method before ordering, since driver and control compatibility must be checked as a system. Also request cut-length information, connector details, and installation guidance for the chosen product.
Working with a COB Linear Light Supplier
For a useful quotation, provide the application, desired light effect, approximate quantity, run lengths, installation location, voltage preference, and any requirements for color, dimming, or protection. Share drawings or profile dimensions when available, especially for recessed details and repeated runs. This gives a supplier more context than a request for a COB strip by name alone.
At ENTA Lighting, we work with B2B buyers to clarify product and project requirements for indoor lighting. We recommend confirming the proposed product configuration, datasheet, driver arrangement, accessories, and sample or approval process before committing to a specification. For projects with multiple installation zones, request a written schedule so that product details and quantities can be reviewed together.
Conclusion: What to Do Next
