630 Chips/m RGB COB Strip: Specifications, Applications, and Selection Guide
A 630 chips/m RGB COB strip is a flexible linear light source that combines red, green, and blue LEDs in a dense chip-on-board (COB) layout. The high chip density can create a more visually continuous line of color than widely spaced LED packages, making it useful for indoor coves, display features, joinery, and other applications where the light source may be visible. For procurement, however, “630 chips/m” is only one specification: buyers should also confirm voltage, power, cut interval, control method, color performance, dimensions, and installation conditions.
You can find more information on our web, so please take a look.
At ENTA Lighting, we recommend matching the strip to the complete project rather than selecting by density alone. The exact electrical and optical characteristics vary by product configuration, so a current datasheet and a sample evaluation should guide final approval.
Who This Guide Is For
This guide is for lighting distributors, contractors, designers, OEM buyers, and project teams sourcing RGB COB tape for indoor applications. It is relevant if you need a compact linear RGB light source and want to assess both installation requirements and supply details before requesting a quotation. It can also help buyers compare product offers that use similar chip-density descriptions but differ in control, construction, or electrical specifications.
What 630 Chips/m RGB COB Means
Chip density and COB construction
“630 chips/m” describes a nominal density of 630 LED chips per meter of strip. If the chips are evenly distributed, the average pitch is approximately 1.59 mm, calculated by dividing 1,000 mm by 630; actual layout and visible light uniformity depend on the product design and optical materials. COB construction mounts closely spaced LED chips on a substrate and covers them with a phosphor or encapsulation layer, depending on the product design.
In an RGB version, the light output is created by mixing red, green, and blue channels. RGB COB describes the light-emitting construction, not necessarily the control system: a strip may be designed for a particular analog or IC-based control arrangement. Buyers should confirm channel wiring, controller compatibility, and whether the product supports the required effects before ordering.
Specifications to Review Before Buying
The product label alone does not provide enough information to size a power supply or specify a control system. Ask the supplier for the complete technical sheet for the exact configuration, and compare like-for-like values across quotations. The following items are especially important for indoor project evaluation.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Input voltage | Rated voltage and compatible power supply | It determines the electrical system and installation plan. |
| Power | Rated watts per meter and total system load | It is needed to size the driver and assess wiring requirements. |
| Control method | Analog or IC-based control, wiring, and controller requirements | It determines color effects and system compatibility. |
| Cutting and connection | Cut interval, polarity, connector type, and feed points | It affects layout flexibility and installation labor. |
| Physical construction | Strip width, thickness, substrate, and encapsulation | It must fit the channel, profile, or cabinet detail. |
| Operating conditions | Indoor suitability, temperature limits, and IP rating if applicable | It helps establish whether the strip suits the environment. |
Voltage must be confirmed for the selected SKU rather than inferred from the product category. Strip systems are commonly offered in 12 V or 24 V configurations, but availability and electrical performance are product-specific. Likewise, do not estimate wattage, brightness, or maximum run length from chip density; obtain those values from the supplier’s datasheet and confirm them against the planned installation.
Applications and Product Matching
Architectural and decorative indoor lighting
The dense layout can be considered for coves, recessed details, ceiling features, and indirect lighting where a smooth-looking colored line is part of the design intent. A diffuser or profile may further soften the appearance, but its material, depth, and transmission can affect the final output. Review the assembled detail rather than judging the strip in isolation.

Retail displays, signage, and furniture
RGB COB strips can be evaluated for shelves, display cases, reception areas, and illuminated joinery when dynamic color is required. For short display sections, confirm the cut interval and how each segment will connect to the controller. In furniture or enclosed details, also check heat dissipation, available space, and access for maintenance.
These strips are not automatically the right choice for every indoor project. If the brief requires accurate white illumination, compare the RGB option with a dedicated white or tunable-white product; RGB color mixing may not meet the project’s color-quality requirements. If independent pixel effects are needed, verify that the selected control architecture supports them rather than assuming that COB construction provides addressability.
A Practical Selection Framework
- Define the visual result. Decide whether the project needs static color, dimming, changing effects, or individually controlled sections. Specify the viewing distance and whether the strip will be visible directly or behind a diffuser.
- Check the physical fit. Record the available channel width, strip length, corners, and cut locations. Compare those measurements with the product width, bend limitations, and cut interval in the datasheet.
- Confirm electrical compatibility. Match the strip’s rated voltage and power to the power supply, controller, wiring, and total installation length. Ask the supplier for guidance on feed points and voltage-drop considerations for the proposed layout.
- Review optical and control requirements. Request the relevant color, dimming, and control information, then test the intended controller with a sample. Where color consistency is important across multiple sections, agree on an evaluation method before bulk approval.
- Validate the installation environment. Confirm indoor conditions, enclosure details, heat management, and any required ingress protection. Do not treat an IP rating as implied; check that the quoted construction and connectors match the actual use conditions.
- Approve a representative sample. Test the strip with the planned profile, diffuser, power supply, and controller. Record the approved configuration so production and installation teams can refer to the same specification.
Pricing, MOQ, and Lead-Time Considerations
Pricing for a 630 chips/m RGB COB strip depends on the specified electrical design, control type, strip dimensions, encapsulation, packaging, and order quantity. Custom colors, connectors, reel lengths, or labeling may also affect the quotation if they are available for the requested configuration. Because these details are not fixed by chip density, buyers should request a quote against a written specification rather than compare a single price per meter.
MOQ and lead time can vary with the selected product and whether the request uses a standard configuration or requires customization. For a reliable schedule, provide the expected quantity, required delivery window, destination, and sample-approval date when requesting pricing. Ask the supplier to state the quoted MOQ, production lead time, sample availability, and any assumptions in writing.
Supplier Evaluation Checklist
A suitable supplier should be able to identify the exact product configuration and provide documentation that supports technical review. Ask whether the supplier can clarify voltage, power, cut interval, control method, dimensions, and applicable environmental ratings for the quoted item. Confirm how sample approval, production changes, packaging, and shipment documentation will be handled.
For project sourcing, also evaluate the supplier’s ability to respond to technical questions and maintain a clear record of agreed specifications. Request relevant product documents rather than relying on broad descriptions such as “high brightness” or “excellent quality.” If a requirement cannot be verified from the available data, treat it as an open item and resolve it before purchase approval.
Key Takeaways and Next Steps
- 630 chips/m indicates a dense COB layout; its nominal average chip pitch is approximately 1.59 mm, but it does not by itself guarantee a specific visual result.
- Confirm voltage, watts per meter, control architecture, cut interval, dimensions, and environmental suitability for the exact SKU.
- Match the product to the application, controller, power supply, and installation profile, then evaluate a representative sample.
- Request MOQ, lead time, and pricing against a complete written specification because these terms depend on the configuration and order.
In short, a 630 chips/m RGB COB strip is worth considering when an indoor project needs dense RGB lighting in a flexible linear format, but the right choice depends on the full electrical, optical, and installation requirements. Start by defining the visual effect and layout, then verify the datasheet and test a sample with the intended control gear.
