Assembly work can vary from large, easy to see tasks to small tasks with high visual difficulty. Additionally colour discrimination may be important. The degree of difficulty of the task must be understood to ensure the right kind of lighting.

In areas with lower ceilings fluorescent lighting is most suitable. The advantages are the ability to produce fairly shadow free conditions, a wide choice of lamps of different colour rendering capabilities and colour appearance, plus the ease of using lighting controls and emergency lighting.

For ceiling heights of 6m or less, care should be taken when using low bay luminaires to prevent excessive glare.
Lighting should take into account the safety of pedestrians in the presence of moving vehicles such as forklift trucks.
