The lighthouse survived its first winter but was in need of repair, and was subsequently changed to a dodecagonal (12 sided) stone clad exterior on a timber framed construction with an octagonal top section as can be seen in the later drawings or paintings. (This gives rise to the claims that there have been five lighthouses on Eddystone Rock.) The octagonal top section (or 'lantern') was high and in diameter, its eight windows each made up of 36 individual glass panes. It was lit by '60 candles at a time, besides a great hanging lamp'.
