Fresnel glass lighting uses concentric ridges to focus and intensify light, originally developed for lighthouse lenses in the 19th century. These shades provide a clean, technical aesthetic and are valued for both their function and visual texture.
Fresnel lenses were often used in marine lighting, railway signals, and naval fittings — typically encased in cast aluminium or brass housings. Their precise beam control and durability make them ideal for exterior use or high-glare environments, while also serving well in minimalist, utilitarian interiors.
