Already have your favorite surface-mounted fixtures but want to install them on the lawn? Our universal ground spikes will let you transform almost any small lamp with a "U" bracket into a garden spotlight. Simply screw the fixture to the flat head of the spike and drive the whole assembly into the ground. We offer spikes in various lengths (15 cm and 26.5 cm), allowing stable installation in both hard compacted soil and looser bark or gravel in flower beds.
