This page documents all of the high-mast lantern installations I've encountered on my travels around the UK. They vary in application, lamp-type, shape, age, and more. High-Masts typically have a height between 14m-30m. Each high-mast lantern has it's own page where photos and information on them is stored. They are listed alphabetically, sorted into groups based on their manufacturer. This page also includes spot-lights.
