Understanding Different Drivers of Luminaires

In the world of premium outdoor lighting, the performance of a luminaire depends not just on its physical build, optics, or LED chip, but also on the quality and functionality of its driver. At Unilamp, we integrate a range of driver options tailored to meet different lighting control needs, energy strategies, and installation scenarios. Below is a comprehensive overview of the various drivers used in our products, including how they work, where they’re best applied, and what makes each one unique.

 

CASAMBI — Wireless Control via Bluetooth

CASAMBI is a wireless control system based on Bluetooth Low Energy (BLE) technology. Unlike traditional wired control systems, CASAMBI-enabled luminaires can be configured and managed through a mobile app without additional infrastructure. The system creates a self-healing mesh network, meaning each luminaire can communicate with others to extend signal range and reliability.

Suitable For

This driver is ideal for outdoor applications where wiring control cables is either too costly or physically challenging—such as in landscaped parks, historical areas, or retrofit projects. CASAMBI allows users to group luminaires, set timers, create scenes, and adjust brightness remotely, providing convenience and flexibility with minimal maintenance. It's also scalable, making it suitable for both small and large outdoor spaces.

Key Features

• Wireless Bluetooth mesh communication
• Mobile app control (iOS and Android)
• Grouping, dimming, scene setting
• No additional wiring required
• Scalable for both small and large projects

 

DALI — Precision and Programmability

DALI, or Digital Addressable Lighting Interface, is a globally recognized protocol for wired lighting control. In a DALI system, each luminaire is assigned an individual address and can be controlled independently or in groups. This enables precise adjustment of light levels, scheduling, and diagnostics.

Suitable For

DALI drivers are well-suited for complex outdoor environments such as public plazas, architectural facades, transportation hubs, and campuses where centralized lighting control is necessary. The two-way communication allows building management systems to monitor the status of each luminaire, detect faults, and optimize performance. DALI’s structured control offers high reliability and is a preferred choice for projects with strict control and compliance requirements.

Key Features

• Fully addressable digital control
• Supports dimming, scene management, and scheduling
• Two-way communication for diagnostics
• Centralized system integration
• Ideal for large-scale or commercial outdoor applications

 

DIM 1-10V — Simple Analog Dimming

The 1-10V dimming system is a simple and widely-used analog control method. It works by sending a voltage signal—ranging from 1V (minimum light output) to 10V (maximum brightness)—from a controller to the driver.

Suitable For

This type of driver is often selected for commercial and industrial projects that need consistent dimming performance without the complexity of digital protocols. It’s effective in applications like perimeter lighting, large parking lots, and storage yards. While it doesn’t support feedback or detailed control, its ease of use and cost-efficiency make it a practical choice for many outdoor environments.

Key Features

• Analog dimming from 10% to 100%
• Easy integration with standard dimmers
• Stable and flicker-free operation
• Cost-effective control solution
• Suitable for perimeter, area, and industrial lighting

 

DMX — Dynamic Control for Visual Effects

Originally developed for theatrical lighting, DMX (Digital Multiplex) is now a powerful solution in architectural and outdoor lighting where dynamic color control is required. DMX drivers control multiple lighting parameters—such as color, brightness, speed, and sequence—via digital channels.

Suitable For

Unilamp integrates DMX drivers into luminaires used for RGB or RGBW applications, enabling vibrant light shows, animated effects, and synchronized color transitions. This is ideal for architectural facades, bridges, monuments, and public installations where lighting is part of a visual identity or storytelling. DMX systems allow for real-time programming, giving lighting designers full creative control over the atmosphere of a space.

Key Features

• Multi-channel control for color mixing
• Real-time programming and synchronization
• Supports RGB/RGBW fixtures
• Excellent for creative lighting displays
• Compatible with standard DMX controllers

 

MPPT — Efficient Power for Solar Lighting

MPPT, or Maximum Power Point Tracking, is a technology used in drivers for solar-powered luminaires. This driver constantly monitors the voltage and current from solar panels and dynamically adjusts the input to operate at the most efficient power point.

Suitable For

In outdoor environments where grid power is unavailable or undesirable, such as remote trails, parks, and off-grid installations, MPPT drivers maximize energy conversion and ensure the battery is charged efficiently. They adapt to changing weather conditions and light intensity, extending battery life and delivering reliable lighting even during low sunlight periods.

Key Features

• Intelligent tracking for solar efficiency
• Increases battery charging speed and lifespan
• Ensures reliable light output in cloudy conditions
• Ideal for off-grid and remote lighting applications
• Integrates with solar panels and batteries seamlessly

 

On-Off — Standard Driver for Basic Control

The On-Off driver is the most straightforward driver configuration. It provides constant power to the luminaire and allows simple operation using a switch, timer, or photocell. There is no dimming capability or advanced control involved.

Suitable For

This type of driver is best used in areas where fixed illumination is sufficient, such as security lighting, signage, or general street lighting. Its simplicity ensures durability and minimal points of failure. On-Off drivers are favored in applications where reliability is more critical than controllability, and where maintenance access may be limited.

Key Features

• Basic operation with no control wiring
• Compatible with timers, photocells, and manual switches
• High durability and low maintenance
• Simple installation and setup
• Suitable for general area lighting and security applications

 

On-Off / DALI — Dual Mode Flexibility

A dual-mode driver that supports both On-Off operation and DALI control offers a flexible solution for projects with evolving requirements. The luminaire can initially function with a basic On-Off switch and later be integrated into a DALI system without needing to replace the driver.

Suitable For

This is particularly beneficial for phased developments or projects that begin with basic functionality but may require advanced control in the future. It simplifies installation planning and reduces the need for costly retrofits later on. These drivers deliver both short-term simplicity and long-term adaptability.

Key Features

• Dual operation mode (basic or advanced)
• Upgradeable without driver replacement
• Ideal for phased projects or future-proof installations
• Saves time and cost in retrofits
• Provides flexibility in design planning

 

Remote — External Installation

A remote driver setup separates the power supply from the luminaire itself. Instead of housing the driver inside the fixture, it is installed externally, typically in a weatherproof junction box or electrical cabinet. This design offers several advantages, especially for outdoor luminaires with limited internal space or exposure to harsh environmental conditions.

Suitable For

Remote drivers improve heat dissipation, extend component lifespan, and make maintenance more accessible—especially in recessed inground lights, bollards, or underwater fixtures where internal space is extremely limited. If a driver needs replacement, it can be serviced without dismantling the entire luminaire.

Key Features

• Driver installed outside the luminaire
• Enhances heat dissipation and component lifespan
• Facilitates easier driver replacement
• Ideal for inground, bollards, and underwater fixtures
• Supports clean luminaire design with compact form

 

Each luminaire driver is used for different purposes.

Understanding the function and application of each driver type is essential for making the right choice in outdoor lighting design. At Unilamp, our driver options are carefully selected to match the intended use, performance expectations, and environmental demands of premium outdoor luminaires. Whether your project calls for simple control, wireless flexibility, dynamic color programming, or solar-powered efficiency, our product line ensures that you get reliable, high-quality performance every time.
