Steelman — All-in-One Solar Street Light

Overview

Steelman combines the solar panel, LiFePO4 battery, LED source and intelligent controller in a single die-cast body. There is no cabling between panel and luminaire, no trenching and no grid connection — installation is one bracket and two bolts.

Where it is used

• Residential footpaths and courtyards (6 m)
• Municipal cycle lanes and parks (6–8 m)
• Main roads and large plazas (8–12 m)
• Off-grid villages, islands and construction sites
