## 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.
