630 Chips/m RGB COB Strip: A Buyer’s Guide to Features, Compatibility, and Applications
A 630 chips/m RGB COB strip is a flexible linear light source with a high density of RGB LED chips mounted on a circuit board and covered by a COB-style luminous surface. Its defining density is 630 chips per meter, equivalent to an average spacing of about 1.59 mm between chips. For buyers, the key is to confirm more than chip density: voltage, power, control method, cut points, strip width, and installation conditions all affect whether a product will work in a specific project.
At ENTA Lighting, we recommend treating the strip, controller, power supply, wiring, and mounting profile as one system. The right configuration depends on the required color effects, run length, installation environment, and control platform. This guide explains what to check before requesting samples or a quotation.
Quick Takeaways
- 630 chips/m describes chip density; it does not, by itself, specify brightness, power consumption, color quality, or compatibility.
- Confirm whether the product uses a common-anode or common-cathode arrangement and whether it is analog RGB or an addressable type.
- Match the strip’s rated voltage and power requirements with the power supply, controller, wiring, and planned run length.
- For a reliable quotation, share the intended application, installation details, control system, and required strip length.
Who This Guide Is For
This guide is for lighting distributors, contractors, OEM buyers, and project specifiers evaluating RGB COB tape for indoor applications. It is useful when comparing product descriptions that list chip density but omit details needed for system design. Buyers can also use it to prepare a more complete RFQ and reduce avoidable specification gaps.
What Does 630 Chips/m RGB COB Mean?
Understanding the construction and density
COB, or chip-on-board, describes a construction in which multiple LED chips are mounted closely on a substrate and covered by a continuous-looking encapsulating layer. In an RGB version, the light output is controlled using red, green, and blue channels to create colors and, depending on the control system, color-changing effects. The visible result depends on the strip’s construction, diffuser or profile, viewing distance, and control settings.
The figure 630 chips/m refers to the number of chips per meter, not necessarily the number of independently controllable pixels. Dividing 1,000 mm by 630 gives an average chip spacing of approximately 1.59 mm. A dense arrangement may help create a more continuous-looking line than widely spaced emitters, but buyers should assess the complete installation rather than infer a guaranteed visual result from density alone.
What the chip count does not tell you
Chip density does not establish wattage, lumens, operating voltage, color consistency, CRI, beam angle, or lifetime. It also does not confirm whether the strip is dimmable, addressable, or compatible with a specific controller. These values and functions must be verified in the product datasheet and quotation for the exact model.
Features and Specifications to Compare
When evaluating a 630 chips/m RGB COB strip, request a model-specific specification sheet rather than relying on a general product description. The table below highlights the details that influence system compatibility and project suitability. If a specification is not stated, ask the supplier to confirm it in writing.
| Specification | Why it matters | What to confirm |
|---|---|---|
| Rated voltage and power | Determines power-supply selection and informs electrical planning. | Voltage, watts per meter, and any project-specific supply limits. |
| RGB circuit and control type | Determines how colors are mixed and what control equipment is needed. | Analog or addressable operation, channel arrangement, and controller requirements. |
| Cut points and connection method | Sets the available trimming intervals and installation approach. | Cut-mark spacing, connector type, polarity, and soldering requirements. |
| Dimensions and installation conditions | Affects fit in channels, coves, furniture, or signage details. | Strip width, thickness, bend guidance, and appropriate indoor use conditions. |
| Optical and material details | Influences appearance, protection, and fit with a diffuser or profile. | Color output information, encapsulation material, and available product options. |
Compatibility: Check the Whole Lighting System
Power supply and wiring
Start with the strip’s stated voltage and power per meter, then calculate the load for the planned length using the supplier’s model-specific data. Select a compatible power supply and confirm the wiring method, connection polarity, and any limits on continuous runs. Voltage drop can affect performance over long runs, so ask the supplier or project engineer to review feed points and cable sizing for the actual layout.

Controller and RGB channels
Match the controller to the strip’s electrical arrangement and control method. An analog RGB strip generally requires compatible red, green, and blue channel outputs, while an addressable product may need a specific data protocol and controller; the terms are not interchangeable. Confirm the common terminal arrangement, controller output rating, dimming behavior, and whether the desired control platform is supported before ordering.
Profiles, diffusers, and installation
Check the strip width against the internal dimensions of the aluminum profile or mounting channel. A diffuser can change the perceived appearance and brightness, so assess the strip in the intended profile when visual uniformity is important. Also confirm the surface preparation, heat-management approach, and whether the specified product is suitable for the installation environment.
Where RGB COB Strips May Be Used
Indoor applications can include architectural coves, retail display details, hospitality interiors, furniture accents, and signage where controllable color is part of the design. The high chip density may be useful where a close-spaced luminous line is preferred, especially when the strip is viewed through a suitable diffuser or profile. Final suitability depends on required brightness, viewing distance, environmental conditions, and the project’s color-control needs.
For task lighting or applications requiring accurate white light, do not assume that RGB output will meet the specification. RGB color mixing and a dedicated white LED product serve different design requirements. If the project needs both color effects and high-quality white illumination, ask whether an RGBW option or a separate white-light circuit is more appropriate.
Buyer Selection Framework
- Define the visual goal. Specify the desired colors, effects, viewing distance, and whether a continuous-looking line is important.
- Confirm the electrical design. Provide the planned strip length, voltage preference if already defined, power supply arrangement, and controller or control platform.
- Check physical fit. Share the profile dimensions, installation route, cut requirements, and connection locations.
- Request the exact model data. Review power, voltage, control type, cut intervals, dimensions, and any available optical or material information.
- Evaluate samples in context. Test the strip with the intended controller, power supply, and profile before approving a larger order.
Pricing, MOQ, and Lead-Time Questions
Pricing can vary with the specified model, order quantity, customization, packaging, and accessories. MOQ and lead time are likewise supplier- and order-dependent, so they should be confirmed for the requested configuration rather than assumed from a general catalog listing. Ask for separate pricing where useful for the strip, connectors, controller, power supply, and any custom labeling or packaging.
For a meaningful quotation, include the target quantity, destination market, required delivery timing, and whether samples are needed. If the project has a fixed launch or installation date, request the current production and shipping schedule before confirming the order. These details help both sides identify practical sourcing constraints early.
Supplier Evaluation Checklist
- Can the supplier provide a datasheet for the exact 630 chips/m RGB COB model?
- Are voltage, power, control type, cut points, dimensions, and connection details clearly stated?
- Can the supplier confirm compatibility with the buyer’s controller and power-supply plan?
- Are sample availability, MOQ, lead time, packaging, and customization terms clear in the quotation?
- Is there a defined process for reviewing samples and resolving specification questions before production?
Conclusion: What to Do Before You Buy
A 630 chips/m RGB COB strip can be a suitable option for indoor projects that need a dense RGB light source, but chip density alone is not enough to establish performance or compatibility. Confirm the exact product’s electrical, control, mechanical, and installation specifications, then evaluate it with the intended accessories and profile. This approach gives your team a stronger basis for comparing suppliers and approving a project-ready configuration.
