The 213mm clear polycarbonate lens sits over the LED array inside the high bay housing, redirecting light into a tighter cone suited to higher mounting heights or targeted task areas.\u003c\/p\u003e\n\u003cp\u003eDesigned for warehouses, industrial units and commercial spaces where the high bay is mounted at ceiling heights of 6-10m or above, the 60° lens concentrates light downward rather than spreading it broadly across the floor. This increases illuminance (lux levels) directly beneath the fitting while reducing spill onto walls and adjacent areas, making it useful for aisle lighting, packing stations and zones needing higher light intensity without adding more fixtures.\u003c\/p\u003e\n\u003cp\u003eThe polycarbonate construction withstands the heat output of the LED array inside the POTHB1 and resists impact and thermal stress better than glass. The lens clips or screws into place inside the high bay housing depending on the POTHB1 variant, and is supplied as a replacement or upgrade component rather than a retrofit for other high bay models. The clear finish maintains the colour rendering of the LED source without tinting or diffusing the output beyond the beam angle control.\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\u003e213 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_5670521_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this compatible with other high bay models?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This lens is sized and designed specifically for the Knightsbridge POTHB1 high bay.

This 60° lens narrows the distribution for higher mounting heights or focused task lighting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the lens fitted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFitting method depends on the POTHB1 variant. Most high bay lenses clip or screw into place inside the housing after removing the outer cover.
