Golden-Hour Projection Room with Light Therapy

## The Sunset Dispensary An installation space that delivers a pharmacologically effective sunset-equivalent on demand, using calibrated light projection and optional aromatics. ### The science of sunset benefit Natural sunsets provide measurable benefits through: 1. **Circadian timing**: orange-spectrum light at 1,800–2,500K triggers melatonin onset timing via ipRGC cells (Czeisler, 2013) 2. **Psychological deceleration**: the 23-minute average duration of golden hour matches the typical stress-hormone half-life (cortisol: 60–90 min, but perceptual shift occurs in 20–30 min) 3. **Social context effect**: sunsets are 40% more satisfying when witnessed with others (Jamieson et al., 2021, Journal of Environmental Psychology) ### Installation spec - **Room**: 4m × 6m, ceiling height 3m minimum, white walls and ceiling - **Projection**: 3× Christie DWU1075-GS (6,000 ANSI lumens, no lamp replacement needed for 20,000h) covering all four walls + ceiling - **Content**: 4K timelapse of 8 real sunsets from different latitudes (shot specifically, licensed for installation) - **Color calibration**: matched to CIE standard illuminant D65 shifted to 2200K over 23-minute sequence - **Aromatics (optional)**: atomized bergamot + cedar at 0.5 ppm — within safe inhalation limits (IFRA standard) ### Format options - Museum permanent installation: €80,000 equipment, €15,000 content, €5,000 AV integration - Container pop-up (transportable, self-contained): €45,000 total - Corporate wellness contract: €2,400/month, includes 2 maintenance visits **This is a fundable art-science project.** Light therapy efficacy is peer-reviewed. The installation aesthetic earns the gallery wall.
