The 267mm diameter clear lens clips into the POTHB2 housing, redirecting light downward for task zones, workbenches and aisles where higher centre-beam intensity is needed than the factory default provides.\u003c\/p\u003e\n\u003cp\u003eDesigned for warehouse, workshop and industrial environments where the POTHB2 is already installed, the lens allows beam customisation without replacing the entire fixture. The 60° beam angle suits mounting heights of 6-10m above floor level where a tighter pool of light is needed on a specific work area rather than broad ambient coverage. The lens does not reduce total lumen output — it redistributes the same light into a smaller footprint with higher intensity at the centre.\u003c\/p\u003e\n\u003cp\u003eThe polycarbonate construction withstands the heat generated by high-wattage LED high bays and resists impact damage during installation or accidental contact with lifting equipment. The clear finish maintains the colour temperature and CRI of the POTHB2's LED array without introducing colour shift. Fitting the lens typically takes 5-10 minutes with the high bay powered off and accessible from a platform or ladder.\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\u003e267 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eClear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5\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_5670523_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWill this lens fit other high bay models?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This lens is designed specifically for the Knightsbridge POTHB2 high bay. The 267mm diameter and mounting mechanism are matched to that fixture and will not fit other brands or models without modification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the lens reduce the light output?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe lens does not reduce total lumens — it redistributes the same light output into a narrower 60° beam instead of the standard 120° spread. This increases centre-beam intensity while reducing the width of the lit area on the floor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat mounting height suits a 60° beam?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 60° beam angle works well at mounting heights of 6-10m above floor level. At 8m height, a 60° beam produces a roughly 5.6m diameter pool of light on the floor, compared to the wider 13.8m diameter produced by a 120° beam at the same height.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the lens be fitted to an already-installed high bay?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The lens clips into the POTHB2 housing. Power off the high bay, access the fixture from a platform or ladder, and clip the lens into place. The process typically takes 5-10 minutes per fixture.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293684785419,"sku":"POTHB2L60","price":4.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1455304_8222dda6-0e20-44b3-be2e-768594fdc269.jpg?v=1714662558","url":"https:\/\/niori.co.uk\/products\/60-polycarbonate-lens-accessory-for-pothb2-high-bay-267mm","provider":"Niori","version":"1.0","type":"link"}
