LED Power Supplies & Drivers
Constant voltage 12V and 24V LED drivers for LED strip – from 15W to 320W, including IP67 waterproof drivers for outdoor use. Use the calculator below to find the right size in seconds.
Which LED driver do I need?
Enter your strip details – we size the driver at 80% load for a long, reliable life.
How to choose an LED driver
LED strip runs on low-voltage DC, so it needs a constant voltage driver (power supply) matching the strip's voltage – a 24V strip needs a 24V driver, a 12V strip a 12V driver.
Work out the wattage: multiply the strip length by its watts per metre. Then choose a driver so the strip uses no more than 80% of its rating – this keeps it cool and extends its life.
| Strip | Total load | Driver |
|---|---|---|
| 3m × 10W/m (24V) | 30W | 40W 24V |
| 5m × 10W/m (24V) | 50W | 75W 24V |
| 10m × 10W/m (24V) | 100W | 150W 24V |
| 5m × 7.2W/m (12V) | 36W | 50W 12V |
Want to dim? Choose a TRIAC dimmable driver for standard wall dimmers, or add a wireless smart controller. For gardens, bathrooms and damp areas choose an IP67 driver.
LED driver FAQs
What size LED driver do I need?
Add up the watts of all the strip on the driver (length × W/m) and divide by 0.8. For 5m of 10W/m strip (50W) you need at least 62.5W, so a 75W driver.
Can I use a 12V driver with 24V strip?
No. The driver voltage must match the strip – 12V strip needs a 12V driver and 24V strip needs a 24V driver.
Can I dim LED strip with these drivers?
Yes – either choose a TRIAC dimmable driver to work with standard mains wall dimmers, or add one of our wireless smart controllers and receivers between the driver and the strip.
Can I use a driver outdoors?
Only an IP67 waterproof driver should be installed outdoors or in damp locations. Our standard drivers are for indoor, dry locations.
Can one driver power several strips?
Yes, as long as the total wattage of all the strips stays below 80% of the driver's rating.
