Why a perfect LED strip looks uneven on site.

The last metre tells a story.

A strip can look excellent on a sample bench and disappoint at the end of a long installation. The installed result depends on the complete circuit: the supply, cable, connectors, controller and copper tracks in the strip. A visible change in brightness is a reason to investigate that system before replacing the light source.

Specify the route, not just the reel.

A product schedule that lists metres of strip and a driver wattage leaves important decisions open. Mark feed locations and cable distances on the drawing. Include the actual circuit length rather than the distance measured in a straight line. Long runs may require separately fed sections, with the arrangement checked against the strip and controller instructions.

• Record rated voltage, watts per metre and the length of every section.
• Identify the longest cable path and the cable cross-section proposed by the installer.
• Confirm connector and controller current ratings.
• Keep each continuous run within the model’s stated maximum length.

A diffuser cannot correct an electrical problem.

Diffusion, channel depth and LED spacing influence visible dots. They do not compensate for an inadequate feed. Test the final strip, profile and diffuser together at the intended viewing distance. If the sample changes colour or brightness along its length, record where that change begins and check the supply voltage under load.

What to include in your RFQ.

Send a marked plan, the length and power of each strip run, the desired colour temperature, dimming method and intended driver location. Ask for a circuit-by-circuit response rather than one total wattage. Have the qualified installer confirm cable sizing, protection and mains connections for the actual site.
