Background: despite developments a substantial part of patients with depression will only recover slowly. Light therapy from light boxes has shown antidepressant effects but have several limitations: time consuming, only allowing a fixed spectral distribution, only delivered at a specific time-point, and often with inadequate light intensity delivered at the retina. Therefore, we developed a new dynamic lighting system using light fixtures that are built into the room and can change intensity and spectral distribution of light during the 24-hour day.
Objectives: the objective of this trial is to assess the beneficial and harmful effects of a newly developed dynamic lighting system using Light Emitting Diodes (LED) -light armatures aiming to mimic sunlight, when installed in the patient rooms of a psychiatric inpatient ward, compared with usual care.
Design: the design is a randomised controlled trial with two arms: an active dynamic light trial arm and a usual care arm with blinding of depression outcome, and data analyses. Randomisation will be 1:1.
Inclusion criteria: a current episode of a major depressive episode as part of a unipolar or bipolar disorder. Patients with bipolar depression should be in current and recent (minimum two months before admission) mood stabilising treatment, age > 18 years, informed consent.
Exclusion criteria: severe suicidality, abuse of alcohol and / or drugs, actual psychotic state, Young Mania Rating score above 7 or fulfilling diagnostic criteria for a current hypomanic or manic episode.
Interventions: the experimental intervention is a dynamic LED-light system in 10 separate patient single rooms with three dynamic lamps: a window jamb built-in light panel, two ceiling mounted lamps, and a wall mounted lamp. The usual care is constant standard LED-light.
Primary outcome: score on the Hamilton Depression Rating Scale 6 item version (HAM-D6) scale at week 3
Secondary outcomes: score on the Suicidal Ideation Attribution Scale (SIDAS ) scale at week 3, and score in the Hamilton. Depression Rating Scale 17 item version (HAM-D17) scale at week 3, and score on the World Health Organisation Quality Of Life questionaire abbreviated version (WHOQOL-BREF) at week 3.
Trial size: in total, 150 patients.
Time schedule: the trial will be submitted for regulatory approvals January 2019, the first participant will be included April 2019, the expected last follow-up of the last participant will be December 2020, the expected last follow-up after 6 months will be June 2021, data will be analysed from June 2021 till September 2021, manuscripts will be prepared from December 2020, and we expect to submit first manuscript December 2021.

Experimental: Dynamic light
The experimental intervention is the installation of a dynamic LED-light system in 10 separate patient single rooms. The system includes three elements: a window jamb built-in light panel, two ceiling mounted lamps, and a wall mounted lamp. All lamps will have a dynamic, time dependent frequency distribution and intensity of light.
Device: Dynamic Light

Placebo Comparator: Usual care
The usual care is constant standard LED-light with two elements: two ceiling mounted lamps and a wall mounted lamp.
Device: Usual care

- Hamilton Depression Rating Scale 6 item version [ Time Frame: Up to 3 weeks ]A scale, consisting of 7 items from the Hamilton depression Rating Scale, measuring severity of depression. Total scores from zero (no depression) to 24 (most severe depression)
- Score on the SIDAS scale [ Time Frame: Up to 3 weeks ]Suicidal Ideation Attributes Scale (SIDAS). A scale measuring suicidal ideation. Total scores from zero (no suicidal ideation) to 50 (highest level of suicidal ideation).
- Hamilton Depression Rating Scale 17 item version [ Time Frame: Up to 3 weeks ]A Scale, consisting of 17 items of the Hamilton Depression Rating Scale, measuring severity of depression. Total scores from zero (no depression) to 52 (most severe depression)
- WHOQOL-BREF [ Time Frame: Up to 3 weeks ]Quality of life scale with four domains. Each scores is transformed to a zero (lowest quality of life) to 100 (highest quality of life) score.
