High‑Efficiency Toy Store LED Track Lighting – Madrid, Spain
Project Overview
A newly built 950 m² (10,225 sq ft) toy store in Madrid, Spain opened in June 2026. The owner required an extremely high illuminance level (≥1000 lux) to make toy packaging and colors exceptionally vibrant, while keeping energy costs reasonable. This new construction project allowed full design freedom. The store includes themed zones, wide aisles, and a central play area.
Background & Compliance Drivers
Spain’s building energy code CTE limits retail lighting power density to ≤12 W/m². By targeting 1000 lux at 6.9 W/m², the store achieves a 42% energy reduction compared to code baseline – complying with regulations while delivering superior brightness.
Engineering & Operational Challenges
- Ultra‑high illuminance requirement: 1000 lux average, good uniformity (U₀ ≥0.6).
- High ceiling (4–6 m) and wide spans require 90° beam angle.
- Flexibility for future rearrangements: track‑mounted luminaires preferred.
- Glare control: UGR <22 in play areas.
- Budget: cost‑effective yet high‑performance.
Solution: T‑LINE LED Track Linear Light (1500mm / 59”)
Luminaire Selection & Placement
FusionBrite supplied 110 units of the T‑LINE LED Track Linear Light (1500mm / 59”, 60W, 4000K, 90° beam angle, CRI 80, 180 lm/W). Installation layout:
- Main aisles: 70 units at 5 m height, spaced 2.5 m apart → average 1050 lux.
- Perimeter shelving (vertical illumination): 30 units aimed at 45° → 1100 lux on product facings.
- Central play & demo zone: 10 units with diffuse lens → 900 lux uniform, UGR 19.
Photometric Performance
Each fixture delivers 10,800 lm. Total installed power: 6,600 W → power density = 6,600W / 950 m² = 6.95 W/m². 4000K neutral white and CRI 80 ensure accurate color rendering.
Quantified Results & Compliance
| Metric | Design Target / Baseline Code | Installed Performance | Improvement vs Target | Data Source | Verification Method |
|---|---|---|---|---|---|
| Power density (W/m²) | CTE limit: 12.0 | 6.95 | 42% better | Calculation | Post‑install measurement |
| Average illuminance (lux) | 1000 (client requirement) | 1010 | +1% | DIAlux simulation | On‑site lux meter |
| Uniformity (U₀) | ≥0.6 | 0.67 | +12% | DIAlux simulation | Field verification |
| UGR (play area) | <22 | 19 | Pass | Manufacturer data | Visual inspection |
| Annual energy consumption | 12 W/m² × 950m² × 4,380h = 49,932 kWh | 6.95 W/m² × 950m² × 4,380h = 28,920 kWh | 21,012 kWh saved | Calculated (12h/day, 365 days) | Utility bill projection |
All lighting complies with CTE DB‑HE and UNE‑EN 12464‑1.
