630 Chips/m RGB COB Strip Buying Guide: Specifications, Controls, and Applications
A 630 chips/m RGB COB strip is a flexible linear light source with red, green, and blue emitters arranged at a high density on a strip and integrated into a COB-style light-emitting surface. Its defining specification is the chip density: 630 chips per meter equals a nominal spacing of approximately 1.59 mm between chips. For B2B buyers, choosing one successfully means checking more than density: confirm the electrical specifications, controller compatibility, installation conditions, and the appearance required by the project.
In this guide, we explain the specifications that matter, how to match controls and applications, and what to confirm with a supplier before ordering. At ENTA Lighting, we help buyers assess these details against their project requirements rather than assuming that one configuration suits every installation. The exact voltage, power, cut interval, protection rating, and control method must be verified for the specific product being quoted.
Who This Buying Guide Is For
This guide is intended for lighting distributors, contractors, project specifiers, and OEM buyers sourcing RGB linear lighting for indoor environments. It is particularly useful if you need a continuous-looking colored light line for joinery, display features, coves, shelving, or decorative architectural details. It can also help procurement teams compare quotations where the product descriptions mention similar chip density but leave important electrical or control details unclear.
Before requesting a quotation, define the installation location, desired colors and effects, approximate run length, control system, and whether the strip will be visible directly or through a diffuser. These details influence product selection, accessories, and installation planning. If you are replacing an existing strip, record its voltage, connector or wiring arrangement, and controller type where available.
What 630 Chips/m Means in an RGB COB Strip
Density and light appearance
The figure “630 chips/m” describes the number of LED chips placed along each meter of strip; it does not, by itself, state brightness, wattage, color accuracy, or energy consumption. Dividing 1,000 mm by 630 gives an approximate chip pitch of 1.59 mm. A close arrangement can help create a visually continuous line, though the final appearance also depends on the COB construction, installation surface, viewing distance, and any diffuser or channel used.
RGB means the strip produces color by controlling red, green, and blue light channels. The controller combines these channels to create colors and effects, but color output and mixing can vary with the strip design, controller settings, and surrounding materials. For projects requiring a specific color appearance, request product details and assess a sample in the intended installation conditions.
Specifications to verify before ordering
Chip density is only one part of a product specification. Ask the supplier to provide a product datasheet for the exact configuration, including electrical ratings and installation limitations. Do not infer these values from “630 chips/m” alone.
| Specification | Why it matters to the buyer | What to confirm |
|---|---|---|
| Rated voltage and power | Determines power-supply selection and electrical planning. | Rated voltage, watts per meter, and recommended supply capacity for the run. |
| Cut interval and connection method | Affects layout flexibility and how sections can be joined. | Cut marks, minimum segment length, and approved connection approach. |
| Control protocol and channel arrangement | Must match the controller or building-control setup. | Whether the strip is analog or addressable and the compatible controller type. |
| Dimensions and installation conditions | Determines fit in profiles, channels, and project details. | Strip width, thickness, bend limits, operating conditions, and protection rating if required. |
Control Options and Compatibility
Control compatibility should be settled before the strip is specified, not after installation. RGB products can use different channel arrangements and control methods, so a controller that works with one strip is not automatically suitable for another. Ask the supplier to confirm the strip’s control type, wiring diagram, and compatible controller requirements in writing.
Analog RGB and addressable control
With an analog RGB configuration, the controller typically adjusts the red, green, and blue channels together along the connected strip section. This can suit applications where one color or effect is required across the full run. Addressable products, by contrast, can allow control of sections or pixels individually, but the product must specifically support that function and use a compatible data controller.
Do not assume that high chip density means pixel-level control. The “630 chips/m” figure describes chip quantity, not the number of independently controlled zones. If the project needs chasing effects or segmented color, confirm the addressable architecture and control resolution with the manufacturer before selecting the product.

Power and run planning
Use the quoted watts per meter and rated voltage to plan the power supply and wiring; these values are product-specific and are not defined by chip density. As a basic calculation, a 5 m run rated at 10 W/m would require 50 W before allowing for appropriate design margin. This is an illustrative example, not a specification for every 630 chips/m RGB COB strip.
For longer installations, ask about the manufacturer’s recommended maximum continuous run and power-feed arrangement. Voltage drop, wiring length, controller capacity, and installation conditions can affect performance. Have the project electrician or qualified installer confirm the final electrical design against the product documentation and applicable local requirements.
Applications and Product Matching
High-density RGB COB strips may be considered for indoor decorative and feature lighting where a close-spaced colored line is desired. Potential applications include retail displays, hospitality interiors, shelving, signage details, furniture, and architectural coves. Whether a particular strip is suitable depends on its verified output, mounting method, environment, and control requirements.
Match the product to the installation
- For visible linear details: Check the strip’s appearance in the intended profile and diffuser, as well as the viewing distance and surface finish.
- For changing colors or scenes: Confirm the controller supports the required RGB operation and any planned scene-setting workflow.
- For long continuous runs: Review the maximum run guidance, power-feed plan, wiring distance, and controller load.
- For damp or exposed locations: Verify the specified protection rating and installation conditions; do not treat an indoor product as suitable for exposure without confirmation.
- For precise color requirements: Request a sample or written product details and evaluate it with the project’s surfaces and control system.
Selection Framework for B2B Buyers
1. Define the visual and functional brief
Record whether the priority is a smooth-looking line, color flexibility, dynamic effects, or integration with an existing control system. Specify the installation location and the viewing conditions. This brief helps suppliers recommend a product configuration and identify any requirements that the strip alone cannot meet.
2. Compare complete specifications
Compare quotations using the same information: voltage, watts per meter, dimensions, cut interval, control method, connection details, and applicable environmental rating. Ask whether the listed values relate to the exact strip configuration being offered. Where a key item is missing, treat it as an open technical question rather than assuming equivalence.
3. Confirm procurement and project details
Price, minimum order quantity, and lead time can depend on configuration, order volume, packaging, and current production scheduling. Request these terms with the quotation, and confirm whether samples, custom lengths, connectors, or packaging options are available for the specific order. Agree on the datasheet revision and sample approval process before placing a production order.
Supplier Evaluation Checklist
A reliable supplier should be able to explain the product configuration and provide documentation that supports the quoted specifications. Ask how the supplier handles sample requests, customization, production scheduling, and technical questions during installation planning. For export orders, also confirm packaging details, shipping terms, and the documents required for your destination and purchasing process.
- Can the supplier provide a datasheet and wiring diagram for the quoted configuration?
- Are voltage, power per meter, cut interval, dimensions, and control type clearly stated?
- Can the supplier confirm controller compatibility and recommended power-feed planning?
- Are MOQ, quotation validity, lead time, and customization options documented?
- Can the supplier support sample evaluation and clarify any application limitations?
Key Takeaways and Next Steps
A 630 chips/m RGB COB strip is defined by a high chip density, with a nominal spacing of approximately 1.59 mm, but density alone does not determine brightness, power, control capability, or suitability. Choose the strip by matching verified electrical and mechanical specifications to the installation, then confirm that the controller and power plan are compatible. For accurate sourcing, request the exact product datasheet and clarify application conditions before comparing price or lead time.
