Calculate LED driver loading for linear fixture runs — LED strip, trunking, and continuous linear systems. Finds how many drivers are needed, maximum run length per driver, voltage drop on low-voltage systems, and recommended cable cross-section. Prevents overloading and ensures voltage drop stays within the 3% limit.
