A 400 chips/m COB LED strip is a flexible light source built with 400 LED chips per meter, arranged beneath a continuous phosphor coating. This construction can create a more visually continuous line of light than many widely spaced LED strips, making it useful for exposed linear lighting and shallow-profile installations. However, chip density alone does not tell you the strip’s brightness, power consumption, color quality, or suitability for a particular project. I recommend evaluating it alongside voltage, watts per meter, lumens per meter, color temperature, color rendering, dimensions, thermal conditions, and the required control system.

This guide is intended for lighting distributors, contractors, project specifiers, OEM buyers, and other B2B purchasers assessing COB linear lighting for indoor use. It is especially relevant if you need a smooth-looking line of light in a visible installation or want to compare COB construction with other flexible LED strip options. The right choice depends on the appearance you need and the electrical and mechanical conditions at the installation site. Treat the figures discussed below as selection guidance, not as specifications for every 400 chips/m product.
“400 chips/m” refers to the number of LED chips mounted along one meter of strip. It means there are 40 chips per 100 mm, based on the stated density. In a COB, or chip-on-board, strip, many small LED chips are mounted close together and covered by a continuous phosphor layer, which can help soften the appearance of individual light points.
This construction is often selected when the LED strip itself may be visible, such as in a linear profile, display detail, or architectural accent. The visual result still depends on the strip, the diffuser or lens, the distance from the viewing position, and the mounting surface. A continuous coating does not guarantee an identical appearance in every fixture, so review a sample in a representative installation before approval.
Two strips with the same chip density may differ in electrical design, light output, color consistency, flexibility, and thermal requirements. Do not use chip count as a substitute for lumens per meter or watts per meter. Ask for the full product datasheet, including the exact product version and operating conditions, before comparing offers.
COB strips are available in different color and electrical configurations, and the options vary by product. For indoor projects, buyers commonly need to decide between single-color light and other color or control options. For a single-color linear light, define the requested color temperature and color rendering requirements; do not assume these from the chip density or product name.
Also confirm the strip’s width, thickness, adhesive backing, connection method, and cutting marks. If the strip will sit inside an aluminum profile, compare its physical dimensions with the profile and diffuser before ordering. Ask whether the supplier can provide the needed reel length, connector, or other configuration, and confirm that any customization is reflected in the quotation and datasheet.
| Specification | Why It Matters | What to Confirm |
|---|---|---|
| Chip density | Helps describe the LED layout and potential appearance of the lit line. | Confirm that the quoted model is 400 chips/m and request a sample. |
| Voltage | Must match the power supply and installation design. | Check the rated input voltage, supply compatibility, and wiring plan. |
| Power and light output | These indicate electrical load and expected illumination more directly than chip density. | Request watts per meter and lumens per meter for the specific model. |
| Color temperature and color rendering | Influence how the light looks and how illuminated objects appear. | Specify project targets and ask for the manufacturer’s stated values. |
| Cutting interval and strip dimensions | Affect fit, installation planning, and the amount of usable strip. | Check cutting marks, width, thickness, and connection points. |
| Protection and operating conditions | Determine whether the product is suitable for the intended environment. | Verify the stated IP rating, temperature limits, and installation instructions. |
For example, if a project specifies a 24 V supply, confirm that the selected strip is rated for 24 V rather than assuming compatibility. If you are planning a run longer than a sample length, ask the supplier or project engineer to review the power-feed method and voltage-drop considerations for the actual layout. These figures and decisions must be checked against the selected product and installation; they are not guaranteed by a 400 chips/m rating.

For shelving, counters, display cases, and visible architectural accents, a COB strip may be worth evaluating when a smooth-looking light line is a priority. Check how the strip appears both with and without the selected diffuser, and view it from the angles and distances expected in use. Confirm brightness requirements separately, since a visually continuous line does not necessarily provide enough illumination for a task.
For under-cabinet details, coves, and recessed or surface-mounted profiles, fit and service access matter as much as visual appearance. Measure the available channel and confirm the strip’s width, cable exit, and cutting interval before finalizing the design. Use a compatible power supply and follow product guidance for mounting and heat management, particularly in enclosed or restricted spaces.
Do not select an indoor COB strip for a wet or exposed location without checking its protection rating and installation instructions. Coatings, connectors, and end treatments can affect the protection of the completed assembly. If the project conditions fall outside the product’s stated operating environment, request a more appropriate product option or consult the supplier before purchase.
The price of a 400 chips/m COB strip depends on its configuration and order requirements, so chip density alone is not enough to compare quotations. Voltage, color specification, strip dimensions, protective treatment, accessories, packaging, and customization can all affect the offer. Request quotations against the same written specification so that differences between suppliers are easier to identify.
MOQ and lead time are product- and order-specific. Ask each supplier to state the MOQ for the exact configuration, whether a sample order is possible, the production lead time, and how shipping time is handled. For customized products, confirm which details are standard and which may require additional setup or approval.
At ENTA Lighting, we support B2B buyers evaluating indoor linear lighting by discussing product specifications, application requirements, and configuration options. Share your target dimensions, electrical requirements, quantity, and installation environment so we can help identify the information needed for a suitable quotation. Before purchasing, compare the proposed datasheet with your project specification and approve a representative sample where possible.
A 400 chips/m COB LED strip has 400 LED chips per meter, but that figure alone cannot determine whether it is right for your project. The best choice is the product whose documented electrical, optical, physical, and environmental specifications match the installation. Define your requirements, verify the exact model, and test the strip in a representative setup before committing to a larger order.
For your next step, prepare a brief with the intended application, required light appearance, target output, supply voltage, installation dimensions, quantity, and delivery needs. Send it to ENTA Lighting to discuss available configurations and request a product-specific datasheet and quotation. This gives your team a clear basis for evaluating suitability, cost, and sourcing conditions.
