Yes, lighting can be installed in a shipping container. The safe approach is to define what people must see, have the electrical designer choose suitable luminaires, switching, wiring protection and supply, then complete any permit and inspection required where the unit will be used. A few battery lamps may support brief visits, but fixed workplace lighting is an electrical installation and should not be improvised with extension cords or bare fixtures.
Container lighting starts with the visual task
Place shipping-container lights around loaded shelves
Choose equipment for the actual environment
Protect wiring from cargo and door movement
Use switching that matches entry and emergency behaviour
Permit and inspection rules are provincial and local
Test the finished lighting with the room loaded
Show the electrician the loaded room
Share the task, shelving elevation, entry points, environmental exposure and power source. Ask the quote to identify luminaires, protected wiring, controls, permits, testing and final records.
