10m COB LED Strip: Length, Power Supply, and Installation Guide
A 10m COB LED strip can provide a continuous-looking line of light across a long shelf, cabinet run, ceiling detail, or other indoor feature. To plan it reliably, confirm the strip’s voltage, wattage per metre, cut points, and installation conditions, then size the power supply from the actual product specification. A 10m length does not automatically mean the strip can be powered safely or evenly from one end; voltage drop and wiring layout also matter.
Quick Takeaways
- Calculate total strip load by multiplying its rated watts per metre by the installed length.
- Choose a compatible constant-voltage supply and include suitable capacity above the calculated load, following the strip and power-supply manufacturers’ instructions.
- For a long run, check voltage-drop guidance and consider feeding power at more than one point if the product design allows it.
- Measure the installation route, confirm cut intervals and IP rating, and test the strip before fixing it in place.
Who This Guide Is For
This guide is for lighting buyers, contractors, designers, and project teams considering a 10m COB LED strip for indoor use. It covers the practical decisions that affect ordering and installation: length, power, voltage, mounting surface, and supplier information. Use the examples as planning illustrations, not as specifications for every COB strip.
Before ordering, compare the project requirements with the exact product datasheet. If the strip will be installed in a damp area, enclosed profile, or other challenging location, confirm suitability with the manufacturer rather than relying on a general product description.
What Is a 10m COB LED Strip?
COB means “chip on board.” In a COB LED strip, multiple LED chips are arranged closely on a flexible circuit board and covered by a phosphor layer, creating a more continuous-looking illuminated surface than many widely spaced LED layouts. The visual result, output, and electrical performance still depend on the specific strip construction and its rated specifications.
A 10m strip may be supplied as one reel or as a project-specific length, depending on the supplier. The product’s marked cut points determine where it can be shortened without damaging a circuit section. Do not assume that a reel can be cut at any point or that two cut sections can be joined without the correct connectors or soldering method.
Choose the Right Strip for the Application
Match the light to the task
For concealed accent lighting, a continuous-looking line can help create a clean visual effect along coves, shelves, or cabinetry. For task lighting, assess the strip’s light output, colour temperature, colour-rendering information, diffuser, and distance from the work surface. A COB appearance alone does not establish that a strip will provide enough useful illumination for a particular task.
Check voltage, colour, and protection
Common product options can include different operating voltages, white colour temperatures, colour-rendering levels, and protection ratings. The available options vary by product, so check the datasheet rather than assuming that every combination is offered. For indoor locations exposed to moisture or dust, verify the product’s stated IP rating and whether the connectors and cut ends need additional protection.
How to Plan Length and Power
Step 1: Measure the route
Measure the actual path the strip will follow, including corners, gaps, and the distance to the intended power-supply location. Allow for the space needed by connectors, end caps, and mounting profiles, and avoid stretching the flexible strip to make it fit. If the installation has separate sections, record each section length and how it will be connected.
Next, compare the planned cuts with the product’s specified cut intervals. The total ordered length may need to include extra material for trimming or layout changes, but excess strip should not be folded tightly or hidden where it cannot dissipate heat as intended. Confirm the final cut plan before installation.
Step 2: Calculate the electrical load
Multiply the strip’s rated power per metre by the total powered length. For example, a hypothetical 10m strip rated at 10W/m has a calculated load of 100W: 10m × 10W/m. This example demonstrates the calculation only; use the wattage shown for the exact strip you are purchasing.

Then select a power supply that matches the strip’s required voltage and provides appropriate capacity for the load. In the example above, allowing 20% capacity above the 100W load gives a planning figure of 120W. Confirm the final supply selection against the manufacturer’s guidance, operating conditions, and any applicable electrical requirements.
Step 3: Check current and power-feed layout
For a constant-voltage strip, current can be estimated by dividing power by voltage. In the 100W example, a 24V system draws about 4.17A in total (100W ÷ 24V); the real selection must still account for the product and installation requirements. Use suitable wiring and connectors for the expected current, and observe polarity.
Voltage drop can make the far end of a long run appear dimmer or differ in colour from the section near the feed. The effect depends on the strip design, voltage, conductor size, load, and wiring arrangement, so there is no single feed distance that applies to every 10m product. Check the supplier’s guidance; where permitted, feeding from both ends or dividing the run into separately powered sections may help manage the issue.
Installation Steps
- Inspect and test: Check the strip, connectors, and supply specifications, then test the strip before mounting it permanently.
- Prepare the surface: Make sure the mounting surface is clean, dry, and appropriate for the strip’s adhesive or chosen profile.
- Cut only at marked points: Use the manufacturer’s cut marks and protect exposed contacts at cut ends as specified.
- Connect with the correct polarity: Use compatible connectors or the recommended soldering method, and secure wiring to reduce strain on the strip.
- Mount and retest: Fix the strip without sharp bends or compression, then test the complete run before closing or concealing the installation.
Keep the power supply accessible for inspection and replacement, and provide the ventilation required by its manufacturer. Mains connections should be completed by a qualified professional in accordance with local electrical rules. Do not energize a damaged strip or use a supply with an incompatible output voltage.
Common Planning Mistakes
- Choosing a supply by length alone: Two 10m strips may have different wattage per metre and therefore different total loads.
- Ignoring the far end: A single-end feed may not provide the visual consistency required for every long run.
- Cutting between marks: This can interrupt a circuit or make the remaining section unusable.
- Skipping a test fit: Corners, profiles, and connector clearance can change the usable route length.
- Overlooking the environment: Adhesive, heat management, and ingress protection must suit the actual installation location.
Pricing, MOQ, and Lead-Time Questions
The cost of a 10m COB LED strip depends on its specification and order requirements, including voltage, power, colour options, protection level, packaging, and requested accessories. Minimum order quantities and production lead times are supplier- and project-specific, so request current terms rather than relying on a general estimate. For a project order, ask whether the quotation covers the strip only or also includes power supplies, profiles, connectors, and packaging.
For accurate quotation, provide the required length, installation environment, target light appearance, supply voltage, and estimated order quantity. If you need custom labelling, cut lengths, or coordinated accessories, state this at the enquiry stage so the supplier can confirm feasibility and timing.
Supplier Evaluation Checklist
Ask for a current datasheet that identifies rated voltage, watts per metre, cut intervals, dimensions, available colour options, and protection rating. Confirm the recommended power-supply arrangement for a 10m run and request guidance on wiring, connectors, and voltage-drop considerations. Also clarify sample availability, MOQ, lead time, packaging, and what is included in the quoted price.
At ENTA Lighting, we support B2B buyers with product-specification discussions and sourcing coordination for indoor LED lighting projects. We can review your intended length, application, electrical requirements, and accessory needs to help identify which details require confirmation before ordering. Final product suitability should be assessed against the selected model’s documentation and the conditions at the installation site.
Conclusion: Is a 10m COB LED Strip Right for Your Project?
A 10m COB LED strip can suit an indoor project when its light output, colour, protection level, and electrical requirements match the installation. Measure the route, calculate the load from the strip’s actual watts per metre, select a compatible supply with appropriate capacity, and confirm how the full run should be fed. These steps are more reliable than choosing a power supply or wiring method based on length alone.
Your next step is to prepare a short specification: total length, number of sections, installation location, desired light appearance, supply voltage, and quantity. Share it with your supplier and request the datasheet, power-feed recommendation, MOQ, and lead-time information before placing an order.
