Note: Lower voltage drop percentages (1%) provide better performance but require heavier gauge wire or shorter runs. Higher percentages (5%) allow longer runs but may affect LED performance.
Voltage Drop Calculator
Build power and lighting plans that account for voltage drop. Our voltage drop calculator helps you estimate maximum wire lengths based on gauge and load so your LED installations shine from start to finish.
