Extension Ground Spike 600mm Stainless Steel for Knightsbridge Spike Lights

The Knightsbridge EXT2 is a 600mm stainless steel ground spike designed to replace the standard 110mm spike supplied with Knightsbridge outdoor spike lights. The extended length raises the light head to illuminate taller planting, architectural features, or pathway edges where a higher mounting position is needed.

Installation requires removing the original 110mm spike from the light fitting and replacing it with this 600mm extension. The 12mm diameter shaft fits the same socket as the standard spike, maintaining a secure connection between the light head and the ground anchor. The additional height allows upward-angled spotlights to reach tree canopies, tall shrubs, or wall features without repositioning the base further from the target.

The stainless steel construction resists corrosion in wet soil and withstands freeze-thaw cycles, making it suitable for year-round outdoor use in UK climates. The spike is supplied as a replacement component only and does not include the light fitting itself.

Product Specification Sheet

Which Knightsbridge lights does this spike fit?

The EXT2 fits Knightsbridge outdoor spike lights that ship with a standard 110mm ground spike. Check the spike diameter on your existing fitting before ordering — it should be 12mm to match this extension.

How is the spike installed?

Remove the original 110mm spike from the light fitting by unscrewing or releasing the fixing collar (method varies by model). Insert the 600mm extension spike into the same socket and secure using the same fixing method. Drive the spike into the ground to the desired depth.

What's the effective height gain?

Replacing a 110mm spike with this 600mm version raises the light head by approximately 490mm, assuming both spikes are driven to the same depth in the ground. Actual height depends on soil conditions and how far each spike can be driven in.
