Metrolux has been specifically designed for use in underground rail tunnel systems, employing a prismatic glass refractor to control light output and a die-cast aluminium front frame and body for the durability required for tunnels and a multitude of industrial applications.

Stainless steel quick release door latches allow easy access to the lamp and control gear compartment for quick and simple maintenance. A vital feature for use in tunnels is the special safety mechanism preventing the door from swinging wide open.
