This document provides an analysis and evaluation of the current state of the art with regard to ipRGC-influenced responses to light in applying this knowledge in the context of identified topics to be considered for use in lighting applications. This analysis has taken into consideration published scientific papers, use cases, reports, best-practice guidelines and recommendations, see Annex A. However, evaluation of the results will be based on scientifically validated findings.

Overview

ISO/CIE TR 21783:2022 - "Light and lighting - Integrative lighting - Non-visual effects" is a technical report that analyzes the state of the art for ipRGC‑influenced responses to light (IIL responses) and their application in lighting design. The document synthesizes scientific literature, use cases, best‑practice guidance and validated findings to help integrate visual and non‑visual (circadian and physiological) effects of light into daylighting and electric lighting practice. It is an informative, evidence‑based resource (not a prescriptive standard) intended for designers, researchers and health professionals.

Key topics and technical considerations

Core definitions: integrative lighting, ipRGCs (intrinsically photosensitive retinal ganglion cells), IIL responses, spectrum, illuminance, daylighting and electric lighting.

Evidence classification: effects are grouped as well‑established, moderate, or insufficient based on literature up to 2019.

Practical implementation: design must address both image‑forming and non‑image‑forming pathways - spectrum, intensity, timing, duration and temporal patterns of exposure are central.

Beneficial aims:

Well‑established: synchronization/support of the circadian system; improvement in mood and well‑being.
Moderate evidence: improved sleep quality and next‑day performance; alertness enhancement for night work.
Insufficient evidence: longer‑term academic performance or daytime cognitive boosting (emerging area).

Risk avoidance:

Follow ICNIRP exposure limits to prevent visual injury.
Night exposure can suppress melatonin and alter sleep timing; plan lighting for shift schedules and promote darkness during sleep.
Account for age‑related differences in short‑wavelength sensitivity (e.g., children vs adults).

Implementation guidance: prioritize desired outcomes, consider whole‑day exposure patterns and prior light history of occupants, and adopt a multidisciplinary design team (lighting designers, occupational health, psychologists).

Practical applications - who will use it

Lighting designers and architects implementing human‑centric or integrative lighting schemes.

Facility and building managers (offices, schools, healthcare, eldercare, airports) planning daily light–dark patterns.

Occupational health professionals and shift‑work planners addressing night‑work risks.

Researchers and manufacturers developing spectral control, lighting controls and circadian‑aware systems.

Policy makers and consultants referencing evidence for guidelines and building standards.

Related standards and references

CIE S 017 (International Lighting Vocabulary) and CIE S 026 (spectral and photometric characterization of ipRGC effects) are normative or related references cited in the report. ISO 8995‑1 (visual lighting) and ICNIRP exposure guidance are also relevant.

Keywords: ISO/CIE TR 21783:2022, integrative lighting, non‑visual effects, ipRGC, circadian lighting, melanopsin, daylighting, electric lighting, human‑centric lighting.
