Glass Deck Light Prism - Melon

(1 review) Write a Review


Round, melon-shaped deck prisms with a bronze or stainless steel surround, manufactured in England by Davey & Company. The beautlfully-finished circular prisms are solid glass and have the greatest light output of all Davey's deck prisms.  Note that the glass prism is 140mm deep, so be sure to install only in areas with sufficient head room.  Spare glass prisms can be bought separately.

In this style the glass is set first into the deck using a marine quality mastic (such as a polysulphide or synthetic rubber)  and then the frame is positioned over the rim of the glass and screwed down.  This style of deck light should be used only where there is a suitable depth of deck material to support the prism.  The surround plate secures the prism to the deck but provides no structural support for the glass - see Davey's "deep frame" prisms for thinner decks.

Frames can be chrome plated to match existing deck hardware (an additional charge applies).

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.
