Groundline
In-ground uplighters: Walkover at 70mm for paths, terraces and beds, Driveover at 120mm rated for vehicle loading, and the Grazer linear wall grazer for raking light up a wall from the ground.
Get one thing right: if a wheel could ever reach it, specify drive-over. That includes the corner of the lawn people cut across when turning. A walkover fitting under a car fails once and permanently.
Every set ships with drainage sleeves, and they are not optional. An in-ground fitting sits in a hole that fills with water; IP67 means it survives immersion, not that it should live submerged. Sleeve plus 100–150mm of pea shingle underneath is the difference between a ten-year fitting and a two-year one, and fittings installed without it aren't covered by the guarantee.
