For centuries, sailing ships used Deck Prisms to provide a safe source of natural sunlight to illuminate areas below decks. Now you too can discover the charm and appeal of the past with our classically styled, nautical deck prism ( glass ). Before electricity, light below a vessel's deck was limited. Light below a vessel's deck was provided by candles, oil and kerosene lamps - all dangerous aboard a wooden ship. The deck prism was a clever solution. Laid flush into the deck, the glass prism refracted and dispersed a flood of natural light into the cabin below from a small deck opening without weakening the planks or becoming a fire hazard.
