Glass Prism Light

Bronze Deck Light Prism - Deep Frame Melon

(1 review) Write a Review


Manufactured in England by Davey & Company, these beautlfully-finished melon prisms are solid glass.  The deep bronze frame makes these deck prisms ideal for thinner decks such as steel, aluminium or fibreglass.

The beautlfully-finished deck lights have the greatest light output of all Davey's deck prisms.  Note that the prism is 140mm deep, so be sure to install only in areas with sufficient head room.

The frame is fixed to the deck first and the glass is then set into the frame from the top.  A marine quality black mastic such as a polysulphide or synthetic rubber should be used. To improve adhesion the glass should be abraded first where the sealant touches.

Frames can be chrome plated to order.

The glass prisms are produced today in much the same way as they were 100 years ago, i.e pouring molten glass into an open top mould, cutting the flow (judged by eye) and rubbing over the top.  This process can produce the following imperfections:

a) Lines or ridges on the outside surface of the glass;

b) Bubbles captured within the glass;

c) Slight dipping on the top of the glass as it contracts when it cools down.

None of these in moderation are faults but rather part of the character of this hand made item.

    Beautiful Prism

    Posted by Harry Green on 1st Nov 2015

    This is a great looking product. We installed it yesterday and it looks great and it's amazing how much light it casts even with our winter cover on. The shipping time was fine to make it from Australia to Alaska. Thanks Classic Boat Supplies for good service.
