June 14, 2011 – Holophane says its new Hazardous Wallpack IV luminaires are designed to meet perimeter and security lighting requirements in a range of harsh environments. The luminaires include a borosilicate glass refractor for precise light control, which it says translates into fewer luminaires required to achieve specified light levels. The company has also extended the UL listing to include hazardous Class I, Division 2, making the fixtures suitable for petro-chemical, water and wastewater, pulp and paper, and power generation plants.
