Wire Gauge and Voltage Drop Calculators

For 12 or 24 volt DC systems, we recommend using wire thick enough to maintain at least 11 or 22 volts, respectively, throughout the system. Below those potentials, you may see some dimming in single color systems, and you may see incorrect colors in RGB systems because the red, green and blue diodes do not dim at the same rate. If you use long LED linear lights, such as tape or linkable bars, you will have additional voltage drop within the lighting itself, so wire to additional points in the lighting line, if necessary.
