Single Color COB Linear Light: A B2B Selection Guide

A single-color COB linear light produces one fixed light color from a continuous-looking line of closely spaced LED chips. For B2B projects, the right choice depends on more than appearance: buyers should confirm whether they need a flexible strip or a complete linear fixture, then match voltage, power, color temperature, brightness, dimming, installation conditions, and documentation to the project. Before requesting a quotation, prepare the installation length, control method, and required performance specifications. This guide explains how to compare options and what information to share with a supplier.

Who This Guide Is For

This guide is for lighting distributors, contractors, designers, OEM buyers, and project procurement teams sourcing linear LED products for commercial or residential interiors. It is especially useful when a project calls for a smooth line of light in a cabinet, cove, display, corridor, or architectural detail. The purpose is to help you translate an application into a clear product brief, rather than assume that one COB product fits every installation. Final suitability depends on the selected product’s datasheet and the project’s electrical and environmental requirements.

What Is a Single-Color COB Linear Light?

COB means “chip on board,” a packaging approach in which LED chips are mounted closely together on a substrate. In a linear light, this arrangement can create a more continuous illuminated appearance than widely spaced LED points, particularly when viewed directly or through a suitable diffuser. “Single color” means the product is designed to emit one selected light color, such as warm white, neutral white, cool white, or a specified monochromatic color. It does not mean that the product can change between colors unless a separate tunable or color-changing function is specified.

Flexible Strip or Complete Linear Fixture?

A COB LED strip is a light source that typically needs a compatible power supply, mounting surface or profile, and, where required, a separate dimmer or controller. A complete linear fixture may integrate components such as a housing, diffuser, wiring, or driver, depending on its design. These formats are not interchangeable in every application: a strip can suit a concealed detail, while a fixture may be more appropriate when the project requires a finished, self-contained luminaire. Confirm exactly what is included in the offered product before comparing quotations.

Types, Materials, and Key Specifications

Single-color options are commonly defined by their selected color temperature or color output, while product construction varies by format and intended use. For flexible strips, buyers may need to review the board, encapsulation, adhesive, cut points, and compatible profile. For complete fixtures, the housing, optical cover, mounting method, and driver arrangement may matter more. Request the manufacturer’s product-specific documentation rather than relying on a general description of “COB linear light.”

Specifications to Compare

Color: State the required color temperature in kelvin for white light, or identify the required color for a monochromatic application. As an illustrative brief, a buyer might request 3000 K warm white; this is an example, not a universal recommendation.
Color quality: Specify a color-rendering requirement where it matters, such as CRI ≥90 for a project that prioritizes faithful appearance of products or finishes. Confirm the measurement and tolerances available for the actual product.
Electrical input: Identify the required input voltage and whether the product is constant-voltage or uses another driver arrangement. A 24 V DC system is one possible project specification, not a default for every COB product.
Power and light output: Compare watts per meter and the supplier’s stated lumen output using the same product length and measurement basis. Do not treat higher wattage alone as proof of better efficiency or better project performance.
Optics and appearance: Check the emitting width, diffuser or profile compatibility, viewing distance, and whether the installation exposes the light source. Request a sample if the visual result is critical.
Control and dimming: Specify whether switching, dimming, or another control function is needed. Confirm compatibility among the light, driver, dimmer, and control system before ordering.
Installation conditions: Share the mounting surface, available space, ventilation, exposure to moisture or dust, and intended operating environment. Select an appropriate product and enclosure based on documented suitability.

Match the Light to the Application

For shelves, joinery, and display cases, a continuous-looking line can reduce the appearance of individual LED points, but the final effect still depends on the profile, diffuser, placement, and viewing angle. In coves and indirect architectural details, brightness and color should be assessed in the installed geometry, because reflected light can appear different from a close-up sample. For corridors or general task areas, calculate whether the proposed output and layout meet the design intent instead of choosing by strip appearance alone. In retail or hospitality settings, color consistency and dimming behavior may deserve particular attention.

Check whether the light will be visible to occupants, concealed behind a lip, or aimed at a surface. A visible installation may require a suitable diffuser or carefully selected mounting profile to achieve the desired appearance. A concealed installation may place greater emphasis on output, thermal conditions, and access for maintenance. Where a project has a required lighting level, have the design team verify it through the appropriate calculations or on-site evaluation.

A Practical Selection Framework

Define the use: Record the location, lighting purpose, viewing distance, and whether the product is exposed or concealed.
Set performance requirements: Specify color, target brightness, color quality, dimming needs, and any project-specific electrical requirements.
Confirm the product format: Decide whether you need a strip for integration into a profile or a complete linear fixture, and list the components that must be included.
Check installation constraints: Provide run lengths, feed locations, mounting details, operating conditions, and any relevant local project requirements.
Review samples and documents: Compare the proposed product’s datasheet, wiring guidance, and sample appearance against the brief before approving production.
Confirm commercial terms: Ask for quotation details covering configuration, quantity, packaging, MOQ, production schedule, shipping, and applicable warranty terms.

Common Buyer Mistakes

A frequent mistake is ordering by the phrase “single-color COB” alone, without defining the color temperature, voltage, output, or format. Another is comparing prices for products with different inclusions, such as a strip-only offer against a fixture that includes a housing or driver. Buyers can also overlook the need to verify dimmer compatibility, installation space, and the proposed cut or connection method. A written specification and approved sample help reduce misunderstandings before a larger order.

Pricing, MOQ, and Lead Time

Pricing depends on the selected configuration, material and component choices, order quantity, packaging, and any customization or documentation requirements. Minimum order quantities and lead times can vary by product and production plan, so they should be confirmed in the supplier’s quotation rather than assumed from a catalog listing. For project schedules, ask whether the quoted timing covers production only or also includes packing and shipping. If a project is phased, request a supply plan that reflects the required delivery dates and quantities.

Supplier Evaluation Checklist

Can the supplier provide a product-specific datasheet with clearly stated electrical and optical specifications?
Can they confirm the exact product format, included components, and compatible power or control equipment?
Are sample availability, MOQ, customization options, lead time, packaging, and shipping terms clearly explained?
Can the supplier provide applicable product documentation and clarify which claims or compliance documents relate to the offered configuration and destination market?
Is there a clear process for confirming specifications and resolving questions before order approval?
