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 one of the most-durable LED lanterns on the market.

Birmingham

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.
