The present invention provides a light emitting diode(s), LED, light strip arranged for providing improved color consistency over its length. The LED light strip comprises LED strings positioned along the length of the LED light strip and powered in parallel, for emitting, for example, red, green, blue and white light. The resistance of the supply and return traces, in combination with variations in the current drawn by or the forward voltage of the various LED and resistors used in the LED strings of different color, causes a voltage drop along these traces leading to inconsistent color rendering. By adjusting the resistivity of the traces, such as through providing return paths having different resistances for LED strings of different color, the consistency of the color rendering can be improved. |
