This is commonly caused by voltage drop across a longer LED strip run.

The effect can become more noticeable when the strip is long, the current is high or the power cable is too small for the installation.

Depending on the system, using a higher-voltage strip, supplying power from both ends or adding power injection at additional points may improve brightness consistency.

Also confirm that the power supply has sufficient capacity for the complete installation.

A waterproof LED strip can be suitable for outdoor applications, but the correct product should be selected according to the actual environment and IP rating.

An installation exposed to occasional moisture has different requirements from one exposed to rain, standing water or continuous outdoor conditions.

Connectors, cable joints, controllers and power supplies also need suitable protection. The waterproof rating of the LED strip alone does not automatically make the complete lighting system waterproof.

Not every LED controller is compatible with every LED strip.

Compatibility depends on factors such as strip voltage, color type and control method. Single-color, RGB, RGBW and addressable RGBIC strips require different types of controllers.

Before connecting the system, confirm that the controller supports both the electrical specifications and control type of the LED strip.

If you're unsure, send us the strip model and controller information and we'll help check compatibility.

COB LED strips are designed to produce a more continuous line of light with less visible spotting, making them especially suitable for cabinets, shelves, display lighting and other installations where the strip is visible.

SMD LED strips use individually mounted LEDs and offer a wide range of brightness levels, colors, LED densities and control options.

The better choice depends on the required lighting effect, installation distance, diffuser and budget.

Most LED strips can be cut, but only at the designated cutting marks printed on the PCB.

The distance between cutting points varies depending on the strip voltage, LED layout and circuit design.

Cutting outside the marked position may damage the circuit or cause part of the strip to stop working. Always check the cutting interval of the specific product before cutting.

First, make sure the power supply output voltage matches the voltage of your LED strip.

Then calculate the total power requirement by multiplying the strip's wattage per meter by the total installation length.

It is generally better to select a power supply with some additional capacity rather than operating it continuously at its maximum rated output.

If you send us the strip model and required length, our team can help you calculate the appropriate power supply.

For longer LED strip installations, 24V is generally the more practical option when the same strip is available in both 12V and 24V versions.

A 24V system usually requires less current for the same power level, which can help reduce voltage drop over longer cable and strip runs.

The final choice should still match the LED strip model, installation length, controller and power supply. For very long runs, additional power injection may still be required.

Yes, two 5m LED strips can be connected, but the correct wiring method depends on the strip voltage, power consumption and total run length.  

For longer installations, we generally recommend using a 24V LED strip where available, as it helps reduce voltage drop compared with lower-voltage systems. For a 10m run, powering the strip from both ends or adding power injection may also help maintain more consistent brightness.  

Always make sure the power supply has sufficient capacity for the total wattage of the installation. If you're unsure, send us the LED strip model, required length and installation details, and we'll help you determine the appropriate power supply and wiring method.
