Frequently Asked Questions

Are all LED bulbs dimmable?

No, not all LED bulbs are dimmable. You must buy LED bulbs that are specifically labeled as dimmable; otherwise, they won’t function correctly with dimmer switches. Explore our selection of dimmable LED bulbs for compatible lighting solutions.

Do I need to change my light fittings or drivers to install dimmable LED bulbs?

In most cases, your existing fittings can be used since dimmable LED bulbs are designed to match standard bulb dimensions and bases. However, for low voltage installations, you may need a compatible driver or transformer. For optimal performance, it is advisable to use a trailing-edge dimmer that’s designed specifically for LED lighting.

Can dimmable light bulbs be used outdoors?

Yes, dimmable bulbs are suitable for outdoor use, provided they are installed in fixtures with the proper water-resistant IP rating—such as IP65-rated downlights—and paired with compatible dimmer switches. Browse our range of outdoor lighting to find suitable fixtures.

Why is my dimmable LED light bulb flickering or buzzing?

This often occurs when the bulb isn’t compatible with the dimmer switch. Using an LED bulb that works with trailing-edge dimmers or swapping your dimmer for one designed for LEDs generally resolves the problem. Check our collection of LED bulbs for dimmer-compatible options.

Do dimmable LED bulbs work with standard on/off light switches?

Yes, dimmable LED bulbs function normally with a standard on/off switch. The dimming feature simply requires a compatible dimmer; otherwise, the bulb will operate at full brightness. See our switches collection for installation options.

What is the difference between leading-edge and trailing-edge dimmer switches?

Leading-edge dimmers are typically used for incandescent bulbs and may cause flickering in LEDs. Trailing-edge dimmers are specifically designed for modern LED technology and offer smoother dimming with better compatibility. Learn more in our LED dimmer range.

How can I tell if a bulb is dimmable?

Dimmable bulbs are clearly marked on the packaging, often with symbols indicating compatibility. Look for labeling that states the bulb supports dimming and check if a trailing-edge dimmer is recommended. Browse our LED bulb collection for dimmable options.

Will I save energy using dimmable LED lights?

Yes, when dimmed, LED lights use less electricity, helping you conserve energy and prolong bulb life. They also give you greater control over your lighting environment. Combine your setup with smart home automation for maximum efficiency.
