THE LIGHTING REFERENCE
LIGHTING · SCIENCE · PRACTICE

Control is a sequence of decisions.

Occupancy, daylight, schedules, scenes and overrides need to work together.

01

Separate the strategy from the device

IES education covers occupancy controls, daylighting controls and reduction strategies. A sensor is a device; turning lights down under a declared condition is a strategy. State the intended behavior before selecting hardware. [1]

02

Define the states

Our sequence template names unoccupied, occupied, daylight-sufficient, after-hours and manual-override states. For each, specify affected zones, output behavior, transitions and recovery. These are project decisions, not universal settings.

03

Write the exception

Describe what happens if a sensor fails, a user overrides a scene, power returns or a network is unavailable. Coordinate emergency and life-safety behavior with the responsible specialists and applicable requirements. A comfortable normal scene does not resolve those separate obligations.

04

Check dimming and tuning together

Tunable-white systems vary CCT through spectral tuning. Evaluate requested settings as a combination of color and output, not as independent promises. Test fades and low-end operation with the specified drivers and controls. [2] [3]

05

Commission the sequence

IES LP-6 addresses lighting control systems. Our handover record includes zone drawings, setpoints, schedules, override behavior, test outcomes and an owner training record. Revisit operation after occupancy so an installation can be adjusted using observed behavior. [4]
