**Choose an LED-rated dimmer that is listed as compatible with your exact bulb model.** “Dimmable” means the bulb supports dimming, but compatibility still depends on the dimmer. Manufacturers publish tested bulb–dimmer combinations. [Lutron compatibility guidance](https://support.lutron.com/us/en/product/maestro/component/dimmers/led-cfl/ma-pro/faqs/load-compatibility)

Check these details before buying:

- **Dimming type:** Look in the bulb’s datasheet for *leading-edge* or *trailing-edge* dimming. Trailing-edge LED dimmers are a common choice, but some LEDs require leading-edge control; follow the bulb manufacturer’s recommendation. [Varilight’s dimmer guide](https://www.varilight.co.uk/dimmers/v-com.php)
- **LED load range:** Add up the bulbs’ actual wattages. For example, six 5 W bulbs make a 30 W load. Check that against the dimmer’s **LED-specific** minimum and maximum ratings, plus any maximum bulb count. Use the actual wattage printed on the bulbs, not their “50 W equivalent” figure.

- **Minimum-brightness adjustment:** A dimmer with an adjustable minimum level can help if the bulbs flicker only near the bottom of the dimming range.

Your flickering is consistent with an incompatible dimmer or a load below its minimum. It can also occur when the dimmer takes the bulbs below their supported brightness range, so flickering alone doesn’t establish the cause.

Have an electrician replace the wall dimmer if you’re unsure about mains wiring. If you share the **bulb brand/model, how many bulbs are on the switch, and your country**, I can help check suitable dimmers.
