Why does landscape lighting wire size matter?
Short answer: Wire size affects electrical resistance and how effectively power can be delivered over the distance between the transformer and fixtures.
Wire size affects electrical resistance and how effectively power can be delivered over the distance between the transformer and fixtures. Thinner wire has more resistance, which means more voltage lost along the run.
That is why wire size is a design decision, not a cost-saving opportunity. Undersized wire is one of the most common causes of dim fixtures at the far end of a system.
When we plan a system, the wire gauge is matched to the run length and the load on that run. It is invisible once it is buried, but it determines how the whole system performs.
What we check in Fall Creek
When we look at a property in Fall Creek, we walk it after dark when we can, because that is when the lighting has to work. We look at the architecture, the mature trees, the walkways and steps, and the transformer and wiring that feed the system, then we check it against the landscape lighting service page to see what the property actually needs — what deserves light, what should stay dark, and what needs to be fixed before anything new goes in.
