Modern 12-sided weatherproof lantern house for new steel lattice or existing concrete/masonry lighthouse structures.

Built to withstand 125 mph winds (structure should be similarly designed).
Easily transported to site in knock-down form for assembly on site without the need for additional lifting equipment.
All sections easily bolt together without specialised equipment on top of structure.
Glazing panes tilted outwards at top to prevent mariners observing false flashes from reflections which are safely reflected down towards the sea instead.
Murette fitted with vents for good air circulation to prevent glazing condensation.
Well proven design already in service around the world.
Options of glass or acrylic panes.
Options of GRP or aluminium roof and murette.
Spacious lantern house permits location of controls on inside wall of murette without restricting access around pedestal.

Additional points for consideration

1. Most tall structures during tropical storms attract lightning strikes on or near the structure. Rock mounted structures need to be earthed directly in the sea itself. Steel lattice towers with concrete bases cast in dry soil are equally insulated and must also be earthed.

2. No electrical equipment can withstand a direct lightning hit. Damage from near misses can be reduced with a 'Faraday cage' of lightning conductors on the outside of the lantern house which can be supplied as an optional extra.

3. The positioning of the hatch inside the lantern house or on the parapet needs careful consideration.

4. The (optional) internal pedestal height should be viewed in relation to the available glazing height, emergency light and racon (if any) to be fitted.
