Frequently Asked Questions

What is a TRIAC dimmable LED driver?
A TRIAC dimmable LED driver lets you control LED brightness using a standard wall dimmer. It uses mains phase-cut technology for smooth, flicker-free dimming.
Are TRIAC dimmable LED drivers the same as mains dimmable drivers?
Yes. TRIAC dimmable drivers are often called mains dimmable because they work directly with leading-edge or trailing-edge dimmer switches connected to the 240V AC supply.
Which LED products can I use with TRIAC dimmable drivers?
TRIAC drivers are suitable for constant-voltage LEDs such as LED strips, Neon Flex and signage modules. Always match the driver voltage and wattage to your lighting load.
Can I use any dimmer switch with a TRIAC dimmable driver?
No. You must use a compatible leading-edge or trailing-edge dimmer rated for LED lighting. Standard non-dimmable switches will not provide variable brightness control.
Do you stock TRIAC dimmable drivers from Mean Well or Ecopac?
Yes. We supply selected TRIAC dimmable models from Mean Well and Ecopac, known for reliable performance and compliance with UK safety standards.
Are TRIAC dimmable drivers suitable for commercial and residential use?
Yes. TRIAC drivers are widely used in domestic lighting, shop signage, retail displays and hospitality environments where wall-mounted dimming is required.
