LED Drivers & Power Supplies (PSUs)

LED drivers power low-voltage LED lighting systems safely and reliably, with options available for different voltages, dimming requirements, installation environments and trusted brands. This collection is designed for signmakers, installers and trade buyers who need dependable power supplies for LED strip lights, LED modules and other professional lighting applications.

Choosing the right LED driver usually starts with voltage, load and control requirements. Our range includes drivers for 12V and 24V systems, dimmable LED drivers, outdoor LED drivers for exposed installations, and constant voltage options for common signage and display lighting setups. Whether you are powering retail signage, illuminated lettering or architectural LED lighting, selecting the correct driver helps support stable output, safe operation and long-term performance.

The collection includes specialist sub-categories to help you choose by application and specification, including LED drivers by voltage, dimmable LED drivers, outdoor LED drivers, and leading brand ranges from MEAN WELL and Ecopac. For complete installations, LED drivers are commonly used alongside LED strip lights, controllers and dimmers, and cables and connectors.

Frequently Asked Questions

How do I calculate the correct driver size?
Add up your total LED load in watts and add 20% headroom. Example: 60W of LEDs requires a 75-80W driver minimum. Never run a driver at 100% capacity for long-term reliability.
What's the difference between constant voltage and constant current drivers?
Constant voltage drivers (12V/24V) are for LED strips, neon flex, and modules. Constant current drivers (350mA/700mA) are for LED chips and COB arrays. Using the wrong type will damage your LEDs.
Which IP rating driver do I need?
IP20 for indoor use in dry locations. IP65 for damp locations or outdoor use under cover. IP67 for direct outdoor exposure. The driver's IP rating should match or exceed your LED product's rating.
Can I use one driver for multiple LED strips?
Yes, if the total wattage does not exceed 80% of the driver capacity and all strips use the same voltage. Wire strips in parallel, not series. Use appropriate gauge wire for the total current draw.
What's TRIAC vs 0-10V vs DALI dimming?
TRIAC works with standard wall dimmers, ideal for residential. 0-10V requires separate control wires, common in commercial settings. DALI is digital addressable dimming for smart building systems. Choose based on your control requirements.
How many LED strips can be powered by one power supply?
Work to about 80% of the PSU's rated watts (keep 20% headroom). Quick rule: usable watts = PSU rating x 0.8. Your total strip watts must be less than or equal to usable watts. Feed long runs in parallel and respect each strip's max run length to avoid voltage drop.

How to choose the right LED driver

Choosing the right LED driver depends on voltage, total load, installation environment and whether dimming or control is required. Most signage and low-voltage lighting systems use constant voltage drivers, but selecting the correct specification ensures stable output, safe operation and long-term performance.

Variant / Type Best For Benefits
LED Drivers by Voltage 12V and 24V LED systems Quickly match drivers to LED strip lights and modules
Dimmable LED Drivers Installations requiring brightness control Supports compatible dimming systems for flexible lighting control
Outdoor LED Drivers (IP65 & IP67) External or exposed environments Protected against moisture and dust for reliable outdoor use
Constant Voltage LED Drivers Most signage and display lighting Stable output suited to LED strip lights and LED modules
MEAN WELL & Ecopac LED Drivers Brand-led purchasing Trusted options for trade and professional installations

Choosing by voltage

The first step is to match the driver output to the voltage of your LED lighting. Most systems run on 12V or 24V, so selecting the correct option is essential to avoid damage and ensure consistent performance. Use our LED drivers by voltage collection to quickly find compatible power supplies.

Sizing the driver correctly

To choose the correct LED driver, calculate the total wattage of the LED strip or modules being powered. Add the wattage of all connected lighting and select a driver that exceeds this load. Installers typically allow around 20% spare capacity to maintain stable operation and extend the lifespan of the power supply.

Dimming and control compatibility

Where brightness control is required, a compatible dimmable driver must be used. Dimmable LED drivers are designed to work with lighting control systems, but compatibility between the driver, dimmer and LEDs should always be checked before installation.

Indoor and outdoor installation

Installation environment will influence driver selection. For internal applications, standard drivers are often suitable, while external or exposed installations require additional protection. Our outdoor LED drivers include IP65 and IP67 rated options for more demanding conditions.

Complete your LED lighting system

LED drivers form part of a complete system and are typically used alongside LED strip lights, compatible controllers and dimmers, and suitable cables and connectors to create safe and reliable lighting installations.

LED drivers are widely used across illuminated signage, retail displays, lightboxes, exhibition builds and commercial lighting projects where consistent low-voltage power is essential.

WeLoveLEDs supplies trade-trusted LED drivers from leading brands including MEAN WELL and Ecopac, with UK stock, fast delivery and practical technical support to help you specify with confidence.
