The extended length raises the light fitting approximately 494mm higher, positioning the lamp head at a more useful height for illuminating pathways, planting, and garden features without the light being obscured by ground-level foliage or mulch.\u003c\/p\u003e\n\u003cp\u003eDesigned for use in garden beds, borders, and lawns where standard spike lights sit too low to clear planted areas, the extension spike allows the light to project over taller grasses, perennials, and low shrubs. The 12mm diameter matches the internal socket of most Knightsbridge spike lights, so installation involves removing the original 110mm spike and inserting the EXT3 in its place before pushing the assembly into the ground.\u003c\/p\u003e\n\u003cp\u003eThe black powder-coated steel finish resists corrosion in outdoor conditions and matches the typical black or graphite housings of Knightsbridge's spike light range. The pointed tip aids initial penetration into compacted soil, though pre-drilling or watering the ground beforehand helps in harder clay or stony soils. The spike is sold as a standalone accessory and does not include the light fitting itself.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e604 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_3280379_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhich Knightsbridge spike lights does this fit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 12mm diameter fits most Knightsbridge outdoor spike lights with a removable ground spike.
