| Product definition | A flexible printed circuit board fitted with surface-mounted LEDs, usually supplied on a reel and cut at marked points. | Electrical current flows through the circuit board to the LED packages, which convert electrical energy into visible light. | Confirm the strip construction, cutting marks, solder-pad layout, and whether connectors are included. |
| Portable power input | Common portable versions use 5 V USB power; 12 V and 24 V versions are also widely available but normally require a compatible battery pack or power supply. | A USB power bank, rechargeable battery pack, or external battery supplies low-voltage direct current to the strip. | Check voltage compatibility, connector type, polarity, over-current protection, and whether the power source is included. |
| LED package size | Common package designations include 3528, 2835, and 5050; the numbers generally indicate approximate package dimensions in hundredths of a millimetre, such as 3.5 × 2.8 mm for 3528. | The LED package contains semiconductor chips that emit light when forward current passes through them. | Request actual LED datasheets rather than judging brightness only by package size. |
| LED density | Common configurations include 30, 60, and 120 LEDs per metre. Higher density can reduce visible dark spots and improve uniformity. | More closely spaced LEDs distribute light more evenly, especially when the strip is installed in a shallow channel or close to a surface. | Compare LED count per metre, brightness per metre, power consumption per metre, and measured uniformity. |
| Typical power consumption | Many general-purpose strips are rated around 4.8–14.4 W per metre, although the actual value depends on LED type, density, colour, and brightness setting. | The power requirement determines the necessary battery capacity, wiring size, operating time, and heat-management method. | Use the supplier’s measured wattage at the intended brightness level and leave suitable capacity in the power source. |
| Colour temperature | Typical white-light options range from approximately 2700 K warm white to 6500 K daylight white. Tunable-white products can adjust between two or more colour-temperature ranges. | Different LED phosphor formulations produce different perceived white-light colours. | Request colour-temperature tolerance, colour consistency, and sample approval before mass production. |
| Colour rendering | CRI is used to describe how accurately light reveals colours. General products may be CRI 80 or higher, while higher-colour-quality versions can reach CRI 90 or above. | The LED spectrum affects how natural objects, fabrics, food, and skin tones appear under the strip. | Ask for test data identifying the measurement method, colour temperature, and actual CRI performance. |
| Colour modes and control | Single-colour strips use one LED colour; RGB strips mix red, green, and blue channels; addressable strips control individual LED sections or pixels. | A controller changes channel current or digital data signals to adjust colour, brightness, patterns, and effects. | Verify controller protocol, remote or app compatibility, control range, and data-direction requirements for addressable models. |
| Cutting and installation | Strips can normally be cut only at designated copper-pad intervals. The interval varies by circuit design and voltage. | Cutting at the marked point preserves the electrical circuit; cutting elsewhere can disable part of the strip. | Confirm the minimum cut length, adhesive backing quality, bend radius, connector options, and soldering requirements. |
| Ingress protection | IP20 provides no water protection; IP65 is dust-tight and protected against water jets; IP67 provides protection against temporary immersion under the applicable test conditions. | Silicone, epoxy, tubing, or sealed profiles can protect the circuit from dust and moisture, but they may affect heat dissipation and flexibility. | Request the tested IP rating, test standard, end-cap sealing method, and restrictions on submerged or outdoor use. |
| Thermal management | Higher-output strips generate more heat and may require an aluminium channel or another heat-spreading surface. | Excessive heat can reduce light output, shorten LED life, and accelerate degradation of the circuit and adhesive. | Check the recommended mounting surface, maximum continuous length, operating temperature, and derating guidance. |
| Battery runtime planning | Approximate runtime can be estimated as battery energy in watt-hours divided by strip power in watts, with allowance for conversion losses and controller consumption. | A longer strip, higher brightness, or animated colour effects increase energy consumption and reduce operating time. | Request measured runtime at the required brightness, not only the nominal battery capacity. |
| Supplier product range | A capable supplier may offer multiple voltages, LED densities, colours, waterproof grades, lengths, connectors, controllers, and battery options. | Different combinations allow the same basic lighting technology to be adapted for displays, furniture, events, vehicles, camping, and decorative applications. | Compare technical consistency across models, replacement-part availability, sample support, and production traceability. |
| Quality documentation | Useful documents include electrical specifications, LED or component datasheets, safety test reports, photometric data, and material declarations. | Documentation links the advertised performance to measurable electrical, optical, thermal, and safety characteristics. | Check that documents apply to the exact model, voltage, LED density, controller, and cable configuration being purchased. |
| International purchasing factors | Important commercial variables include sample availability, minimum order quantity, lead time, packaging, spare parts, warranty terms, and destination-market compliance. | Portable lighting systems contain several connected parts, so compatibility and after-sales support can be as important as the LED strip itself. | Confirm plug type, adapter input range, product labelling, carton protection, customs documents, warranty coverage, and replacement procedures. |
