The base is moulded in one-piece strong, coloured, durable polyethylene-filled with highly buoyant polyurethane and UV-stabilised for resitance to sunlight. The strong, lightweight polyethylene buoy top is moulded in standard IALA high visability colours and shapes to suit a range of installation requirements. A powder-coated extension pole may be supplied to increase the focal height of the Sealite lantern, as well as an additional base section for extra buoyancy. For superior night visability, the SLB1250 navigation buoy may be fitted with a range of Sealite solar LED marine lanterns up to 5nm+.
