400 Chips/m vs 480 Chips/m COB LED Strip: Density, Appearance, and Applications
For most projects, a 480 chips/m COB LED strip is the better starting point when the priority is a very smooth, uniform line of light viewed at close range. A 400 chips/m strip can be a practical choice when its appearance already meets the project requirements and the buyer wants to avoid specifying higher chip density without a clear benefit. The difference is 80 chips per meter, or 20% more nominal chips per meter in the 480 chips/m version. However, density alone does not determine brightness, power consumption, color quality, or final appearance.
Quick Summary
- 400 chips/m: A high-density option for many indoor applications, including profiles and concealed details where the viewing distance and diffuser help determine the final look.
- 480 chips/m: Adds 20% more nominal chips per meter and may help create a more uniform-looking line, particularly in close-view installations.
- For both: Compare the actual product’s power, light output, color consistency, dimensions, and operating requirements rather than choosing by chip count alone.
What Does Chips per Meter Mean for COB LED Strips?
In a COB LED strip, many small LED chips are mounted along a flexible circuit board and covered by a phosphor-based coating. The coating helps blend the emitted light into a continuous-looking surface. “Chips per meter” describes the stated number of chips along one meter of strip; it is a density indicator, not a complete measure of performance.
Using the nominal figures, 400 chips/m corresponds to an average spacing of about 2.5 mm between chips, while 480 chips/m corresponds to about 2.08 mm. These are simple spacing estimates based on one meter divided by the stated chip count. Actual construction, chip layout, coating, and optics influence the visible result, so the figures should not be treated as a guaranteed measurement of the finished light line.
400 Chips/m vs 480 Chips/m: Key Differences
| Comparison point | 400 chips/m COB strip | 480 chips/m COB strip |
|---|---|---|
| Nominal chip density | 400 chips per meter | 480 chips per meter |
| Estimated average chip spacing | About 2.5 mm | About 2.08 mm |
| Relative density | Baseline for this comparison | 20% more nominal chips per meter than 400 chips/m |
| Potential visual advantage | Can provide a smooth-looking line, depending on strip and installation | May offer finer light distribution, especially at close viewing distances |
| What density alone cannot confirm | Brightness, watts per meter, color rendering, efficiency, voltage, lifespan, or compatibility | |
Appearance: When Does the Higher Density Matter?
Direct and close-range viewing
When a strip is exposed or viewed close up, small variations in the light line are easier to notice. A 480 chips/m product may be worth evaluating for visible coves, display details, furniture lighting, and other applications where viewers are near the source. The final appearance still depends on the complete optical system, including the strip’s coating, channel, diffuser, mounting position, and surface finish.
Use with profiles and diffusers
An aluminum profile and diffuser can soften or blend the output, so a 400 chips/m strip may be sufficient where the light source is recessed or viewed indirectly. The profile’s depth and diffuser material affect how much blending takes place. We recommend assessing the strip in the intended channel instead of assuming that a higher chip count will always be visible as an improvement.
Applications and Best-Fit Scenarios
Where 400 chips/m may be suitable
Consider 400 chips/m for general indoor accent lighting, concealed cove lighting, shelving, and profile installations when the selected sample provides the required visual continuity. It can also be a sensible option when project cost, specification simplicity, or availability matters and there is no requirement for the highest available density. Confirm the result at the actual viewing distance and with the specified diffuser before approving a large order.
Where 480 chips/m may be suitable
Consider 480 chips/m when the light line will be seen at close range, when a project has a strict appearance requirement, or when the design offers limited space for optical blending. It may also be relevant for premium joinery and display details where a more uniform-looking source is important to the design intent. Request a sample comparison, because the difference may be subtle or more apparent depending on the installation.

What Chip Density Does Not Tell You
A higher chip count does not automatically mean higher brightness. Light output depends on the LEDs and their operating conditions, the strip’s electrical design, and other product characteristics. Similarly, more chips per meter do not by themselves establish that a strip uses more watts per meter or delivers higher efficiency.
Before comparing quotations, request the product’s measured or specified light output, power consumption, input voltage, color temperature, color rendering information, dimensions, and cut length. Also confirm whether the offered data applies to the exact strip configuration being quoted. When comparing two products, keep the installation, color specification, and measurement conditions as consistent as possible.
How B2B Buyers Should Choose
- Define the visual requirement. Decide whether the source is directly visible, viewed at close range, concealed, or covered by a diffuser.
- Set performance targets. Specify required light output, color temperature, color rendering, voltage, and watts per meter instead of using chip count as a substitute.
- Check the installation details. Confirm channel dimensions, diffuser type, mounting surface, strip width, bend requirements, and available space for the driver and wiring.
- Compare samples in context. Review both options in the intended profile and at a representative viewing distance. Evaluate the whole installation, not just the bare strip on a workbench.
- Confirm production and order requirements. Ask the supplier to confirm the exact specification, packaging, order quantity, lead time, and any available customization before placing a purchase order.
Common Comparison and Sourcing Mistakes
- Choosing by density alone: A 480 chips/m label cannot confirm light output, color consistency, or overall product quality.
- Ignoring the optical assembly: A profile or diffuser can change the perceived continuity and brightness of either option.
- Comparing unlike specifications: Strips with different voltage, color temperature, power, or dimensions are not a direct comparison just because their chip counts are stated.
- Skipping sample approval: Review representative samples under the intended installation conditions before confirming a project specification.
- Leaving details open in the purchase order: Record the approved product data and configuration so the quoted item and delivered item can be checked against the same requirements.
Supplier Support and Project Planning
At ENTA Lighting, we help indoor lighting buyers compare COB strip options against project requirements rather than treating chip density as the only decision point. For an accurate product recommendation, share the application, viewing distance, mounting profile, diffuser details, target light output, color specification, voltage, and estimated order quantity. We can then review which product data and samples should be checked for the intended installation.
For sourcing, buyers should also confirm the supplier’s available product configurations, documentation, sample process, packaging, and production schedule for the specific order. These details can vary by product and project, so they should be confirmed during quotation rather than assumed from a general product description. Clear specifications make it easier for both sides to assess suitability and reduce the risk of mismatched expectations.
Conclusion: Which COB LED Strip Should You Choose?
Choose 480 chips/m when close-range appearance and a finer nominal chip spacing are important, and choose 400 chips/m when a sample confirms that its appearance meets the project need. The 480 chips/m option has 20% more nominal chips per meter, but that figure alone does not prove greater brightness, efficiency, or suitability. The right choice depends on the strip’s complete specification and how it performs in the intended profile and viewing conditions.
As a next step, define the required light output and color characteristics, provide your installation details to the supplier, and compare samples under representative conditions. ENTA Lighting can support B2B buyers with product-specification discussions and quotation review for indoor lighting projects.
