LED Drivers & Power Supplies (PSUs) — 12V & 24V

Pick a reliable constant-voltage LED driver / PSU for LED strips and Neon Flex. Match the voltage (12V or 24V), add 20% headroom to your total watts, and choose the right protection: IP20 for dry areas, IP65/IP67 for outdoors or damp spaces. Dimming options available (TRIAC, 0–10 V, PWM).

Voltages: 12V & 24V LED drivers
Protection: IP20 (indoor), IP65/IP67 (outdoor/wet)
Types: Constant voltage with optional dimming
Use cases: LED strips, Neon Flex, signage

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.

Complete Your LED Driver Setup

A reliable LED driver — also called a PSU or LED power supply — is essential for running LED products safely and efficiently. At WeLoveLEDs, we stock high-quality constant-voltage LED drivers in 12V and 24V for use with signage, LED strips, and Neon Flex, with next-day UK delivery available.

Whether you're powering a small DIY LED sign or a large retail installation, the right driver ensures stable performance, longer LED lifespan, and safe operation.

How to Choose the Right LED Driver

Choosing the correct driver can feel confusing — here's what to consider:

Voltage: Match your LED product. Most of our ranges (LED strip lights, Neon Flex, Fairground Lights) run on either 12V or 24V.
Power (Watts): Add up the total watts of your LEDs, then select a driver with at least 20% headroom to avoid overloading.
Location / IP Rating: IP20 for indoor, dry areas. IP65/IP67 for outdoor or damp spaces, offering water and dust protection.
Dimming (Optional): If you want dimming, choose a dimmable driver that matches your control system: TRIAC, 0–10 V, or PWM/DMX.

Constant Voltage vs Constant Current

Constant Voltage (CV): The most common type. Used for LED strips, Neon Flex, and Fairground lighting kits. Supplied in 12V or 24V.
Constant Current (CC): Required only when the LED specifies a current (e.g. 350 mA, 700 mA). Typically used in specialist applications, not our standard ranges.

Compatible with WeLoveLEDs LED strips, Neon Flex, and Fairground Lights
Dimmable driver options for advanced lighting control
Tested and trusted by signage professionals across the UK

Are LED Drivers, PSUs, Power Supplies and Transformers the Same Thing?

These terms often get mixed up, but here's what they really mean:

LED Driver – the catch-all name for the device that powers your LEDs.
LED Power Supply (PSU): Usually the same as a constant voltage driver (12V or 24V), which is what most LED strips and Neon Flex need.
LED Transformer: Strictly reduces AC voltage (e.g. 240V AC to 12V AC). LEDs need DC power, so a transformer on its own isn't enough.

What this means in practice: If you're buying for LED strips, signage, or Neon Flex, you want a constant-voltage LED driver / PSU. LEDs need DC (Direct Current) which is a steady flow of electricity in one direction. “Transformer” is often used in error — avoid it unless you're specifically dealing with AC systems.
