The Maxi is the largest and most powerful lantern in the Highway Diamond series by ASD lighting. Versions of between 110W-350W are available. These come with a wide-variety of total LEDs: 100, 112, 124, 136, 148 or 160. They come with a five year warranty and offer even longer ones, and maintenance on these lanterns requires no tools. They are on of the most durable LED lanterns on the market.

The roads around Chinatown in Birmingham are lit by Highway Diamond™ Maxis. These are on Ladywell Walk.

This 100 LED example looks rather-peculiar mounted side-entry on a stud bracket.
