How many low voltage garden lighting products can I connect to one cable?
A. Adding too many lights onto one cable increases cable voltage drop and reduces the distance the cable can be run before the loss of voltage dims the garden lighting products too much. See the question above for the solution to this. As a rule of thumb, wire a maximum of three 20 watt lights equally spaced along a 10 metre ground burial cable and wire higher power lights individually from the transformer position to allow flexibility in positioning the garden lighting fitting in the future as planting grows or the garden changes.
