Thornbury Brass Norbrook 900mm Avenue Bollard Set of Ten with Transformer and Cable

The tall one, for a long drive or a car park where the spacing has to be 8 to 10 metres and a low fitting would leave dark gaps.

Bollards are sold singly everywhere and almost always bought in fours or more, because one bollard on a path lights nothing. Buying the set gets you the transformer and the cable in the same box, sized correctly, and gets you fittings from the same production batch so the brass ages at the same rate. Unlacquered brass is not a finish so much as a starting point. It arrives bright, goes bronze within a season and settles into a dark green brown after three or four years. If you want it to stay bright, buy the powder coated version instead, because polishing a bollard twice a year is a job nobody keeps up.

Installation

This runs on 12V, which is the reason to choose a low voltage garden system in the first place. The cable can be laid in a shallow trench or clipped along a fence without armoured conduit, it can be cut and joined with waterproof connectors outdoors, and a spade through it is an inconvenience rather than an emergency. The transformer itself is the only part that touches mains, so that is the only part an electrician needs to look at. Bury cable at least 100mm deep, run it along a line you will remember, and leave a loop of slack at every fitting so you can move things next year when the planting has grown.

When to buy

Garden lighting is bought in spring and installed in a hurry. It is much easier to dig a cable run in February when the borders are bare and the ground is soft than in May when everything is in leaf and you are trying not to stand on it. Order in winter, get the cable in, and the first warm evening of the year is ready for you rather than a job list.
