Which Dimmer Switch Works with Dulora Bulbs?
Not all dimmer switches work well with LED bulbs. Using the wrong dimmer is the most common cause of flickering, buzzing and poor dimming performance. This guide explains what to look for, and what to avoid.
The Short Answer
Dulora bulbs are compatible with modern LED trailing-edge (capacitive) dimmers. For customers in Australia and New Zealand, the easiest and most reliable option is our own DimEzy range, which is designed and tested specifically for use with Dulora globes.
Trailing-Edge vs. Leading-Edge Dimmers
| Type | Also Called | Works with LED? | Notes |
|---|---|---|---|
| Trailing-edge | Capacitive, ELV | Recommended | Designed for low-load LEDs, smooth dimming, quiet |
| Leading-edge | TRIAC, phase-cut, resistive | Sometimes | Designed for halogen/incandescent, can cause flicker or buzz with LEDs |
| 0-10V / DALI | Commercial dimming | Yes (specific products) | For commercial/architectural applications |
If you are replacing an older dimmer that was installed for halogen or incandescent bulbs, it is almost certainly a leading-edge dimmer and should be swapped out for a trailing-edge model.
Why Incompatible Dimmers Cause Problems
Leading-edge dimmers work by "chopping" the AC power wave in a way that halogen and incandescent elements can handle easily. LED drivers are more sensitive to these interruptions, which can cause:
- Visible flickering, especially at lower dim levels
- Buzzing or humming from the bulb
- Limited dimming range (e.g., only dims down to 40-50% before flickering)
- Reduced bulb lifespan in some cases
Minimum Load Requirements
Many dimmers have a minimum load rating. For example, a dimmer rated for "20W-300W" needs at least 20W of connected load to operate correctly. Because LED bulbs draw very little power, a single LED bulb may fall below the dimmer's minimum load and cause flickering.
What to do: Choose a dimmer with a low minimum load rating (0W or 1W), or use multiple bulbs on the same circuit to raise the total load.
What About Smart Dimmers?
Smart Wi-Fi or Zigbee dimmers (such as those from Lutron, Clipsal, or C-Bus) can work with Dulora bulbs, provided they are rated for trailing-edge / LED operation. Always check the manufacturer's compatibility list before installing.
The DimEzy range also includes a smart outdoor dimmer for customers who need app-based control in an outdoor setting.
DimEzy: Our Recommended Choice (Australia and New Zealand)
DimEzy is Dulora's own range of LED dimmers, designed and tested for use with our full range of globes. DimEzy dimmers are hardwired units available in rotary knob and push button styles, and must be installed by a licensed electrician.
DimEzy dimmers are currently certified for use in Australia and New Zealand only.

Other Compatible Dimmers
Diginet dimmers are also compatible with Dulora globes and are a good alternative if DimEzy is not available in your region. When choosing any third-party dimmer, look for a trailing-edge (capacitive) model rated for low-load LED use.
