How to Modernize Lighting with Simple, Scalable Solutions
Retrofitting commercial spaces—whether it’s a 1,000 sq. ft. clinic or a 20,000 sq. ft. office—offers a major opportunity to implement energy-efficient LED lighting and smart controls without a full renovation.
With today’s wireless lighting control systems, small to mid-size buildings can achieve the same benefits as new construction—at a fraction of the cost and complexity.
✅ Why Add Smart Control During a Retrofit?
- ⚡ Energy Efficiency: Save 40–60% with occupancy sensing, daylight harvesting, and scheduling.
- 🌞 Comfort & Productivity: Tunable white lighting and dimming support better focus and wellbeing.
- 📱 Simple Setup: Wireless systems reduce labor costs and avoid disruptive rewiring.
- 📏 Code Compliance: Meet energy codes (ASHRAE 90.1, IECC) with built-in control features.

🧠 Typical Setup for 1,000–20,000 Sq. Ft. Projects
For retrofitting spaces with troffers and recessed downlights, here’s a scalable approach using wireless lighting control systems (e.g. nLight AIR, Casambi, or other Bluetooth-based proprietary control ):
1. Smart Fixtures or Retrofit Kits
- Use LED troffers and downlights with 0-10V dimming or built-in wireless drivers (Zigbee, BLE Mesh, or proprietary).
2. Wireless Room or Area Controllers
- Control local circuits and communicate with switches/sensors.
- Install in ceilings or electrical closets with minimal disruption.
3. Wireless Sensors & Switches
- Occupancy/Vacancy Sensors: Detect presence to auto-adjust lighting.
- Daylight Sensors: Dim or turn off lights near windows.
- Wireless Switches/Scene Controllers: Easily reconfigurable by zone.
4. Mobile App or Dashboard
- Configure zones, scenes, schedules, and energy reporting via app or desktop.
- Optional gateways allow cloud access and analytics.

📊 Example Configurations by Size:
🏢 1,000–5,000 sq. ft. Office
- 2 zones (Open Office + Conference)
- 20-30 fixtures (2×4 troffers, downlights)
- 1 wireless controller, 2 occupancy sensors, 2 switches
🏬 5,000–10,000 sq. ft. Retail or Clinic
- 3–5 zones (Sales, Storage, Breakroom, Lobby)
- 50–80 fixtures
- 2–3 wireless controllers, daylight sensors at windows
🏫 10,000–20,000 sq. ft. School or Mixed-Use Facility
- 6–10 zones (Classrooms, Corridors, Admin, Lobby)
- 100–200+ fixtures
- Multiple controllers, gateway for central control, advanced scheduling
🔩 Key Features to Look For:
- Wireless commissioning
- App-based control (no complex wiring)
- Scene programming (presentation mode, cleaning, after-hours)
- Scheduling & demand response
- Compatibility with existing lighting layouts

🧰 Bonus Tip:
Plan for zones. Lighting zones by function (e.g., open offices, meeting rooms, corridors) simplify both installation and user control. Most wireless systems support zone-based logic with flexible sensor/switch pairing.
💼 Who Benefits:
- Office tenants and property managers
- Medical clinics and dental offices
- Retail stores and showrooms
- K-12 classrooms or tutoring centers
- Churches, gyms, and community centers

Modern lighting control is no longer just for new construction. Whether you’re retrofitting 1,000 or 20,000 sq. ft., today’s wireless control solutions are cost-effective, easy to deploy, and make a measurable impact from day one.
