which one lighthouse use meso radial 1125mm focal length lens ?
which one lighthouse use Hyper radial 1330mm focal length lens ?

By the 1920s, high-intensity lamp technology had rendered lenses of this size obsolete.

Meso-radial - Farol de Abrolhos‎, Farol da Ilha Rasa‎ (only two lighthouses)
Hyper-radial - Makapu`u, Cape Race, Nolsoy, Cabo de Sao Vicente, etc.
