01Application definition
Document mounting height, spacing, task plane, surrounding context, environmental exposure, hours, maintenance access, applicable codes, and the decision deadline. Outdoor work also needs site geometry and spill-light boundaries; indoor work needs ceiling, glare, and occupant context.
02Photometric review
Use IES or LDT files for the identified luminaire configuration. Review luminous flux, candela distribution, beam angle, uniformity, illuminance, BUG rating where relevant, and calculation assumptions rather than treating wattage as a performance proxy.
03System coordination
Check input voltage, driver, power factor, total harmonic distortion, surge strategy, 0–10V or DALI-2 interface, occupancy sensors, daylight control, emergency requirements, and commissioning responsibilities at the system level.
04Approval package
Align submittals, schedules, drawings, photometric files, applicable declarations, samples, alternates, and change records. UL, CE, and RoHS credentials are considered only within their stated geography and product scope.
