LED Drivers
LED drivers, sometimes referred to as LED power supplies or LED transformers, are modules designed to regulate and provide the correct power to LED lighting components. They ensure stable performance in both residential and commercial applications, especially for high-wattage LEDs that require precise power management.
Acting as a self-contained power supply, an LED driver converts AC current into the low-voltage DC power required by LEDs. It continuously adjusts power output to accommodate fluctuations in electrical properties caused by temperature changes. This helps prevent overheating, flickering, or performance degradation, ensuring consistent brightness and an extended lifespan for your LED lighting.
Constant Current LED Driver vs. Constant Voltage LED Driver
Constant current LED drivers regulate and maintain a steady current while allowing voltage to fluctuate based on the LED's requirements. These are ideal for powering high-power LEDs as they maintain the same current.
On the other hand, constant voltage LED drivers supply a fixed voltage (e.g., 12V or 24V) while allowing the current to vary. They are commonly used for LED strip lights and other LED products with built-in current regulation, such as those with resistors.
Choosing the right type of driver ensures stable operation, longevity, and optimal performance of your LED lighting system.
Dimmable Drivers
Dimmable LED drivers provide precise control over brightness levels, making them ideal for creating customised lighting environments. They are widely used in commercial settings for mood lighting, energy efficiency, and ambience control.
These drivers support various dimming protocols, including 0-10V, DMX, and DALI, allowing seamless integration with different lighting systems. Whether you need smooth dimming for decorative lighting or adjustable brightness for task-oriented spaces, a dimmable LED driver ensures flexibility and enhanced lighting control.
LED Driver Compatibility with LED Lights & LED Strip Lights
To ensure efficiency and avoid potential issues, it's essential to match the LED driver specifications with your LED system. These are some of the things you need to consider:
Type and Number of LED Lights in Your System
The total number of LEDs and their type determine the voltage and power requirements for the driver. For LED strip lights, a constant voltage driver is typically preferred, while high-power LEDs may require a constant current driver to maintain stable operation.
Input Voltage and Wattage
Ensure that the LED driver matches your region’s input voltage to avoid electrical issues. Also, check that the driver’s wattage capacity is at least 20-30% higher than your LED system’s total wattage to prevent overloading, overheating, and early failure.
Output Power of LED Driver
An LED driver must provide sufficient power to maintain consistent brightness and prevent flickering. Undersized drivers can cause underperformance, while oversized drivers may reduce LED lifespan. Choosing a driver with the right wattage output ensures stable and efficient lighting operation.
Output Voltage and Current
Selecting the right output type is essential for compatibility with your LEDs. For constant voltage drivers, maintain a steady voltage (e.g., 12V or 24V) while allowing current to fluctuate based on the LED load. This is recommended for LED strips and pre-configured lighting systems.
Constant current drivers deliver a stable current while adjusting voltage as needed. This is ideal for high-power LED applications that require a fixed current for consistent brightness.
Matching the driver’s output to your LEDs ensures efficiency and prevents damage.
Safety and Efficiency
To ensure reliability and compliance with safety regulations, always choose LED drivers with recognised certifications in Australia. Certified drivers reduce the risk of electrical hazards and ensure long-term reliability. Also, energy-efficient drivers consume less power, generate less heat, and enhance the lifespan of both the driver and LEDs.
Size and Form Factor
Consider the physical dimensions of the LED driver to make certain it fits within your lighting installation. Compact drivers are ideal for tight spaces, while larger drivers typically offer better heat dissipation and higher power capacity. Also, check mounting options to ensure secure and stable placement.
LED Driver Compliance with Australian Standards
Before purchasing an LED driver in Australia, it is essential to ensure that it meets national safety and performance regulations. Since LED drivers are classified as Level 3 in-scope electrical equipment, they must adhere to the following requirements:
- Electrical Safety & Standards Compliance: The driver must comply with relevant Australian safety standards to ensure reliable and hazard-free operation.
- Regulatory Compliance Mark (RCM): The LED driver must be clearly marked with the RCM symbol, indicating that it meets both electrical safety and electromagnetic compatibility (EMC) requirements.
- Certified for Use in Australia & New Zealand: The product should have a valid Certificate of Conformity issued by an accredited Australian or New Zealand regulatory body.
- Registered in the EESS Database: The LED driver must be listed in the Electrical Equipment Safety System (EESS) database and linked to a registered responsible supplier to confirm compliance with national regulations.
Aside from these requirements, you should also consider the IP rating of the LED driver.
The IP rating of an LED driver represents its water resistance. Lower numbers, such as IP20, are best suited for indoor use. IP44 is suitable for use in areas that may come into contact with water splashes, such as LED strip lighting in a kitchen. IP67 LED drivers are rugged and are ideal for use outdoors, where they could become submerged in water.

Avoid Common Mistakes When Purchasing LED Drivers
Many buyers make errors when selecting LED drivers, leading to inefficiencies or failures. Some key pitfalls to avoid include:
1. Prioritising Low Cost Over Quality
While budget-friendly options may seem appealing, low-quality LED drivers often have poor heat dissipation, leading to overheating and early failure. Investing in a reliable, well-built driver ensures long-term performance and safety.
2. Ignoring Product Specifications
Selecting a driver with the wrong voltage or current rating can cause flickering, reduced brightness, overheating, or even LED burnout. Always match the driver’s output specifications to your LED lighting system to ensure stable and efficient operation.
3. Overlooking Compliance Certifications
Using non-certified LED drivers can result in electrical hazards and regulatory issues. Always check that the driver complies with Australian electrical safety standards and features the Regulatory Compliance Mark (RCM).
Applications of LED Drivers
LED drivers are essential for a wide range of applications across different industries:
- Commercial Lighting: Used in offices, hotels, and retail stores to ensure consistent brightness.
- Industrial Facilities: Powers high-output warehouse and factory lighting.
- Outdoor & Street Lighting: Ensures durability in harsh weather conditions.
- Stage & Architectural Lighting: Supports DMX-controlled LED lighting systems.
