Hyperradiant optics were installed in thirty-one lighthouses around the world. A large proportion were destined for lights around Great
Britain and Ireland, with another four used at sites around Sri Lanka. Despite the improvements in lighting technology, a number are still in use today. Others are

These lenses were originally named biform, and later triform and quadriform lenses, by Wigham. Thomas
Stevenson used the term hyperradiant lens, and later they were renamed the hyper-radial lens by James Kenward of the Chance Brothers Glass Company.

Original 1887 tri-form was re-engineered by dividing up the bullseye panels, and creating a new bi-form optic for use at Mew Island in 1928. The second set of panels were used to create a second bi-form optic that is still in situ and in use.

Made up of four panels, "each lens panel has two partial bull's-eyes giving a double group-flashing characteristic". It is not in the lantern room anymore, the fate of the optic is not known.
