OFFICE LIGHTING FOR LIGHT-SENSITIVE INDIVIDUALS: A PILOT TEST
Bibliographic record
Abstract
Employees with light sensitivities may find conventional office lighting to be unacceptable, leading to requests for accommodations ranging from delamping to relocation. This paper reports a pilot test of an innovative LED luminaire to provide a suitable lit environment for light-sensitive individuals. Fourteen volunteers with either self-identified or medically diagnosed light sensitivities and seven volunteers from the general population (all Canadian public servants) worked for two days in a room lit with recessed luminaires with prismatic lenses and LED lamps (4000 K Ra ~ 84) (reference lighting) and two days in another week in a room with LED luminaires (3500 K, Ra = 90) with innovative optics and dimming control (test lighting). All participants judged the test lighting to have higher lighting quality than the reference lighting. Participants with light sensitivity experienced less intense visual symptoms over the workday in the test lighting, and began the following day with less intense symptoms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
