Non-dimmable LED drivers

FAQs

What is a non-dimmable LED driver?

A non-dimmable LED driver is a power supply designed to provide a fixed level of current or voltage to your LEDs. Unlike dimmable LED drivers, these do not support brightness control or dimming functions – instead, they ensure consistent output for uninterrupted illumination and longevity.

What's the difference between constant current and constant voltage drivers?

• Constant current LED drivers regulate the current flowing through the LEDs, making them ideal for applications where current must be precise (e.g. LED downlights or spotlights wired in series).
• Constant voltage drivers maintain a fixed voltage output (typically 12V or 24V), making them suitable for LED strip lighting or setups wired in parallel.

Always check the product specifications and compatible voltage before choosing a driver for safety and optimal performance.

Why can’t I use a dimmable driver for a non-dimmable application?

Dimmable LED drivers are designed to work with dimming systems, such as DALI or PWM. Using one in a non-dimming application adds unnecessary complexity and cost.

For safety reasons and better efficiency, it’s best to use a non-dimmable driver where dimming isn’t required.

How do I choose the right non-dimmable LED driver?

To select the right LED light driver, consider:

• The voltage and current requirements of your LED
• Whether it’s a constant current or constant voltage setup
• The wattage you need based on your total lighting load
• Compatibility with the LED’s circuit design (series or parallel)
• IP rating if installing in damp or outdoor areas (e.g. near water)

Can I use these drivers with any LED lights?

Non-dimmable LED drivers are compatible with a wide range of fixed-output LED lights, including downlights, spotlights and LED strips.

Just make sure your LED product matches the output and voltage of the driver. Mismatching can damage the light or shorten its lifespan.

How long do non-dimmable LED drivers last?

A high-quality LED driver can last several years, particularly when installed in a well-ventilated area and used within the recommended load range.

Choosing a driver with slightly more power than your LED requires can help extend its service life and prevent overheating.

What lighting setups are non-dimmable LED drivers designed for?

Non-dimmable LED drivers are designed for straightforward lighting setups where dimming control is not required. They’re perfect for commercial strip lighting, domestic downlights or any installation that requires a consistent level of brightness without fluctuations.

This makes them an essential component in both new builds and retrofit lighting plans.

Are non-dimmable LED drivers suitable for LED strips?

Yes, many non-dimmable LED drivers are suitable for LED strip lighting, particularly those that operate on constant voltage (typically 12V or 24V).

Be sure that the driver does not exceed the strip’s voltage, wattage and total length tolerances to ensure safe and efficient operation.

What safety considerations should I keep in mind when using an LED driver?

Always check the driver’s compatibility with your lighting and its suitable voltage rating. Overloading the circuit or using the wrong type of driver (e.g. constant current for a strip that needs constant voltage) can result in poor performance or even damage.

For safety reasons, it’s also important to ensure correct wiring and follow manufacturer installation guidelines.

Can I use non-dimmable LED drivers in series lighting configurations?

Yes, constant current non-dimmable drivers are ideal for LEDs connected in series. This configuration ensures each LED receives the same current, which is important for consistent brightness and extended lifespan.

Be sure to use the correct current rating to avoid overdriving the LEDs.

What is the role of a power supply in an LED lighting setup?

An LED driver acts as a dedicated power supply, converting mains AC power to the direct current (DC) required by LEDs.

This regulation is vital to protect LEDs from voltage spikes and to ensure they operate efficiently. Without the correct driver, LEDs may flicker, overheat or fail prematurely.

Why is efficiency important in an LED driver?

Efficient drivers reduce wasted energy, generate less heat and help lower your long-term energy costs. A good quality non-dimmable LED driver will offer high energy conversion rates and maintain stable output, supporting the longevity of your LEDs and reducing the need for frequent replacements.

Are non-dimmable drivers compatible with smart lighting systems?

While most non-dimmable LED drivers are not intended for smart dimming, they can still be compatible with smart systems that control lights through switching (on/off functions) rather than brightness adjustment.

Always check product specifications and consider whether dimmable drivers are a better match for your smart system needs.
