Lighting for tunnels and underground work

Underground work combines movement through access routes with close equipment inspection and repairs. String assemblies light successive work positions, hand lamps reach around obstructions, and cap lamps keep a personal beam with the worker.

Separate movement from close inspection

String assemblies distribute several light heads along an interior run. A separate hand lamp brings the source closer to connections, machinery and repair surfaces that fall behind equipment or structural obstructions.

Cap lamps keep light aligned with the wearer during movement and close checks. A separately aimed task lamp provides another working view when the worker’s head or tools change position.

Choose the complete electrical arrangement

Cord length, access openings and the position of the work all affect how a lamp reaches the task. Lamp heads, supports and cable assemblies also need a clear route for retrieval after the work.

Underground locations can have specific equipment approvals and supply requirements. Direct-powered lamps and transformer-fed assemblies use different electrical arrangements, even when their light heads have a similar appearance.
