Start with how the warehouse is used
A storage building, distribution facility, manufacturing floor, and service warehouse can all need different light levels. A good review looks at aisles, racking, forklift movement, staging zones, dock doors, packing areas, and maintenance access before choosing fixtures.
Ceiling height changes fixture choice
Low ceilings, tall open bays, and racked aisles need different fixture outputs and beam spreads. Ceiling height also affects lift access and installation planning.
Existing layouts are not always wrong
Many projects can reuse existing fixture locations, especially when the building already has sensible spacing. The walkthrough confirms whether a one-for-one swap is enough or whether dark areas need adjustment.
