Office and collaboration
Screen use, vertical illumination and daylight variability influence distribution and controls. A low UGR target may improve comfort but can reduce delivered lumens or demand tighter spacing.
Legrand lighting for spaces with different demands
A room category is only the starting point. The useful specification connects people, tasks, surfaces, schedules and control behavior.
Application questions worth resolving early
Retail and hospitality
Beam control, TM-30 color fidelity and scene flexibility matter alongside efficacy. High lm/W alone cannot describe contrast, sparkle or how materials appear.
Education
Teaching, presentation and cleaning modes benefit from clear manual override. Sensor timeout and zone logic should follow actual occupancy rather than a generic control schedule.
Healthcare
Visual comfort, maintenance access and cleaning protocols shape the luminaire choice. Medical task requirements and local compliance remain project-specific.
Industrial and warehouse
Mounting height, rack geometry, dust, impact and surge exposure affect optical and electrical selection. Verify IP and IK ratings against the actual environment.
Outdoor approaches
BUG rating, vertical visibility and neighboring properties must be considered together. More output can increase spill and glare without improving the intended task.

These are selection references, not universal requirements. Final values depend on the room, product model, jurisdiction and calculation assumptions. A calculation review should state mounting height, work-plane height, surface reflectances, light-loss factor and the exact IES file revision. Field readings can then be taken on a defined grid after commissioning, with daylight conditions and control state recorded, so modeled and installed results can be compared on the same basis.
