LED Dimmer Compatibility Guide – Get Smooth, Flicker-Free Lighting
Learn which dimmers work best with LED bulbs and how to achieve consistent, flicker-free control across your lights.
Dimmable lighting lets you tune a room from bright and focused to soft and relaxing. Pair a quality LED dimmer with compatible bulbs and you’ll get smooth control, better comfort, and less energy use. This guide covers how dimmers work, which types match LiquidLEDs bulbs, and easy options for plug-in lamps.
Why use an LED dimmer?
- Energy & comfort: Reduce brightness to save power and set the mood.
- Longer lifespan: Lower thermal/electrical stress can extend bulb life.
- Flexible spaces: One room, many uses—reading, dining, movie nights.

Are all LED bulbs dimmable?
No—only bulbs labelled dimmable should be used with a dimmer. We offer dimmable options across both Classic LED Bulbs and Vintage LED Bulbs. If you’re unsure about your current switch, ask us and we’ll confirm compatibility.
Recommended dimmers (mains & low-voltage)
LiquidLEDs 240 V dimmable bulbs work with most modern trailing-edge LED dimmers and many leading-edge types. Tested brands include:
- DimEzy Trailing-Edge 400 W
- DimEzy SMART Dimmer
- DimEzy External Dimmer
- Diginet (Pierlite), Cabac, Dimpala, Lumex
- C-Bus* and DALI-compatible systems*
Low-voltage notes:
- 12/24 V DC bulbs: Use PWM or 1–10 V dimmers.
- 12–24 V AC/DC bulbs: Not dimmable.
Plug-in dimming: inline, foot & hand switches
No rewiring needed—add a cord-mounted dimmer to table and floor lamps:
- Hand Dimmer Switch: Thumb-friendly slider near the lamp—great for desks and bedsides.
- Foot Dimmer Switch: Hands-free control for floor lamps; tap/press to adjust.
- Inline Dimmer Switch: Compact push-button control built into the cord. Perfect for retrofitting decorative lamps without changing fittings.

Getting smooth, flicker-free dimming
Flicker usually comes from a mismatch between the dimmer, the total load, and the bulb driver. For best results:
- Use a modern LED-rated (preferably trailing-edge) dimmer.
- Keep the total wattage within the dimmer’s min/max load.
- Avoid mixing different bulb types on the same dimmer channel.
- If you see shimmer at very low levels, raise brightness slightly or try a different dimmer model.
Our dimmable filament bulbs are engineered for smooth, stable control when paired with compatible dimmers—no special standards required to get good real-world performance.
Important notes on C-Bus and DALI
C-Bus (Clipsal/Schneider) uses phase-cut control that can cause flicker or shortened life if not configured correctly. DALI requires suitable drivers for proper dimming behaviour.
Disclaimer: LiquidLEDs bulbs are not guaranteed to be compatible with all C-Bus installations. Incorrect setup may void warranty. Always use a licensed integrator for automation systems.
How to choose the right dimmer
- Use LED-rated dimmers only (not legacy halogen models).
- Match the method: Trailing-edge tends to give the smoothest result with LEDs.
- Mind the load: Stay within the dimmer’s specified range; too low can cause instability.
- Get help when needed: A licensed electrician can confirm wiring and safety.
Great places to add dimming
- Living room: Slide from bright for reading to low for movie nights.
- Kitchen/dining: High for prep, lower for meals and entertaining.
- Bedroom: Gentle wind-down lighting with bedside control.

FAQs
Can I use old dimmers with LED bulbs?
Sometimes, but it’s hit and miss. Older halogen/incandescent dimmers often cause flicker, hum, or a narrow dimming range with LEDs. For best results, use an LED-rated trailing-edge dimmer and keep the total load within the dimmer’s min/max range.
