The Lighthouse, 1 Point Road, Killough, Downpatrick, BT30 7QY
“Listed building consent is sought for proposed works at St. John’s Point Lighthouse. The proposed works are required to ensure the continued safe and reliable operation of the lighthouse. The project includes the retention of the rotating Fresnel lens and flash character of the light while allowing the removal of mercury and diesel generation from the lighthouse. The existing Fresnel Lens, will continue in operation by installing a mechanical rotational ball-bearing race below the lens, replacing the mercury used in the existing rotation system. The mercury will be removed from the site for responsible disposal by a specialist contractor. It is intended to replace the existing light-source with a low-energy LED light-source, this will enable the replacement of the existing back-up diesel generator and fuel storage with a back-up battery system to be used in the event of mains electrical failure. The existing emergency lights will be replaced with new full-range emergency lights, Sealite SL-300 lights or equivalent, which will only be exhibited in the unlikely event that all other systems fail. The proposal contains a range of ancillary works including the removal of existing electrical cabinets, the relocation of the disused Fog Signal Emitter from the balcony to the Fog Signal Compressor Room (to the southern part of the site), localised repairs to the tower lath and plaster where defective. Any source of damp ingress to the tower will be investigated, if tower lining is beyond repair it will be removed to expose natural stone construction. The existing entrance gate to be repaired if possible, or replaced with similar gate in the existing green colour manufactured using wrought iron and steel in accordance with the original construction methods. The ladder located outside the lantern will be secured in place to provide inadvertent rotation.” (additional Information submitted)
