Collingwood Ground Light Installation Tube - 37mm Diameter

A proper home for your ground light, not just a hole in the dirt

Push a ground light straight into loose soil or fresh concrete and eventually it can shift, tilt, or let water track down the sides. This installation tube gives the fitting a fixed, solid sleeve to sit in instead, so it stays exactly where you set it.

The 37mm diameter version

This is the 37mm diameter tube, made from anodised aluminium. It is sized to suit Collingwood's GL019 range and similar compact ground lights. Wider ground lights use larger diameter tubes, so it is worth checking which one matches your fitting before you order.

How It Works

• The tube is set into the ground first, in concrete, soil or sand.
• The ground light then drops into the tube, using it as a rigid housing rather than relying on the surrounding material to hold its shape.
• A hole is already cut into the tube wall, so the fitting's cable can exit cleanly instead of being squeezed underneath it.

Where It Works Best

This is most useful anywhere the ground around a light is likely to move, settle or wash out over time. Think gravel paths, lawns and planted borders, or any spot where the light sits in soil rather than a solid paved surface. It is also a sensible extra step on new installations generally, since it protects the fitting if the surrounding material shifts after the initial install.

About Collingwood Lighting
