Fortunately, wireless lighting control technology offers a smarter approach.

Keystone SmartLoop® is a Bluetooth® mesh wireless lighting control system designed specifically for commercial LED retrofit projects. It allows compatible fixtures, sensors, and controls to communicate wirelessly, helping contractors modernize lighting systems with less disruption and reduced installation complexity.

Bay Lighting works with contractors, engineers, facility managers, and property owners throughout Maryland, Virginia, and Washington, DC to design commercial lighting retrofit solutions that improve energy efficiency, support code compliance, and simplify installation.

Why Retrofit Lighting Systems Need Smarter Controls

Commercial lighting retrofits today involve much more than replacing fluorescent lamps with LED fixtures.

Modern energy codes increasingly require lighting controls such as:

• Occupancy sensors

• Daylight-responsive controls
• Automatic scheduling
• Time-based shutoff
• Dimming capabilities
• Lighting zoning

While traditional wired lighting control systems can deliver these features, they often require:

• New control wiring
• Additional conduit
• Ceiling demolition
• Longer installation times
• Increased labor costs
• Greater disruption to building occupants

These challenges become even more significant in occupied office buildings, schools, hospitals, retail stores, and government facilities where downtime is costly. Wireless lighting control systems like Keystone SmartLoop eliminate many of these obstacles while providing sophisticated lighting management capabilities.

What Is Keystone SmartLoop?

Keystone SmartLoop is a wireless commercial lighting control system developed to simplify LED lighting retrofits and new commercial lighting installations.

The system is designed to provide:

• Fixture-level lighting control
• Occupancy sensing
• Daylight harvesting
• Wireless grouping
• Lighting schedules
• Space zoning
• Easy commissioning
• Scalable expansion

Because communication occurs wirelessly between compatible SmartLoop devices, contractors can often complete retrofit lighting projects with significantly less infrastructure work than traditional wired control systems require.

How SmartLoop Works: Core System Components

Keystone SmartLoop combines several components into one intelligent lighting ecosystem.

SmartLoop-Enabled Fixtures

Compatible LED fixtures and retrofit kits include SmartLoop-enabled drivers or control devices that communicate wirelessly throughout the building. Each fixture becomes part of the Bluetooth mesh network.

Wireless Sensors

SmartLoop supports various sensor types including occupancy sensors, vacancy sensors, and daylight sensors. These sensors monitor activity and available natural light, automatically adjusting lighting levels based on building use.

For example:

• Empty conference rooms automatically turn lights off.
• Warehouse aisles illuminate when workers enter.
• Window-side fixtures dim when sufficient daylight is available.

Bluetooth Mesh Communication

Instead of each device communicating directly to one central controller, SmartLoop uses a Bluetooth mesh architecture where compatible devices communicate across the network.

This provides:

• Reliable communication
• Improved scalability
• Greater flexibility during expansion
• Reduced infrastructure requirements

Mobile Commissioning

After installation, contractors can configure the system using SmartLoop’s commissioning tools to:

• Create lighting zones
• Assign fixtures
• Configure occupancy settings
• Set daylight harvesting levels
• Program schedules
• Adjust dimming parameters

Many adjustments can be made through software rather than rewiring fixtures.

How SmartLoop Simplifies Commercial Retrofits

One of SmartLoop’s greatest strengths is its ability to modernize older buildings without requiring major electrical renovations.

No Dedicated Control Wiring

Traditional lighting controls often require low-voltage wiring between fixtures, sensors, switches, and controllers. Wireless SmartLoop systems eliminate much of this complexity by allowing compatible devices to communicate wirelessly.

Uses Existing Electrical Infrastructure

Rather than replacing large portions of the building’s electrical system, contractors can often work within existing branch circuits while upgrading fixtures and controls. This reduces labor hours and project duration and can eliminate excess construction debris and demolition of ceilings.

Ideal for Occupied Buildings

Many commercial facilities cannot simply close for lighting renovations.

SmartLoop is well suited for occupied:

• Office buildings
• Retail stores
• Medical offices
• Educational facilities
• Municipal buildings
• Warehouses

Projects can often be completed in phases with minimal disruption to daily operations.

Common Commercial Retrofit Applications

Office Buildings

Businesses replacing fluorescent troffers with LED fixtures gain:

• Occupancy-based lighting
• Conference room scheduling
• Open office zoning
• Daylight harvesting

Warehouses

Industrial facilities frequently benefit from:

• Motion-activated aisle lighting
• High-bay LED controls
• Reduced energy usage during unoccupied periods
• Zoned lighting management

Retail Stores

Retail environments can update lighting without extensive remodeling by implementing wireless controls that minimize installation disruption.

Schools and Universities

Educational facilities often require lighting controls to satisfy current energy code requirements while minimizing disruption to classrooms and administrative spaces.

Government Buildings

Municipal facilities often pursue lighting retrofits to reduce operating costs while improving long-term sustainability.

Installation Process: What Contractors Can Expect

Commercial SmartLoop installations typically follow several stages.

1. Project Evaluation

The retrofit begins with evaluating:

• Fixture types
• Building layout
• Energy goals
• Applicable energy code requirements

2. Lighting Design

A lighting plan is developed that identifies:

• Fixture locations
• Sensor placement
• Lighting zones
• Control strategies

3. Fixture Installation

Existing fixtures may be replaced or upgraded with compatible LED fixtures and SmartLoop-enabled components.

4. Sensor Integration

Occupancy and daylight sensors are installed where appropriate to maximize efficiency.

5. Commissioning

Once hardware is installed, contractors commission the system by:

• Creating lighting groups
• Setting schedules
• Programming sensors
• Configuring dimming
• Testing system operation

Compared to traditional wired lighting controls, commissioning is often simpler because many adjustments are software-based rather than requiring physical rewiring.

Energy Savings and Code Compliance

Lighting represents a substantial portion of electricity use in many commercial buildings, making lighting retrofits one of the most effective energy-efficiency improvements available.

According to the U.S. Department of Energy, lighting can account for roughly 17% of electricity consumption in U.S. commercial buildings, though the percentage varies by building type.

Adding advanced lighting controls can significantly increase savings beyond LED upgrades alone. Occupancy sensing, daylight harvesting, scheduling, and dimming help reduce unnecessary lighting operation during periods of low occupancy or abundant natural light. The U.S. Department of Energy has reported that lighting controls can reduce lighting energy use by 20% to 60%, depending on the application and control strategies employed.

SmartLoop supports many common control strategies that help projects meet the lighting control requirements found in current versions of:
