-Flashing or Flickering Bulbs

-Delayed Dimming 

-Failed Drivers 

To avoid these issues and earn yourself a flicker free life follow our guide to dimming LED Bulbs. 

Check if your bulbs are dimmable

The most common issue with LED bulbs not dimming is certain bulbs are simply not designed to dim. While all Halogen and Incandescent bulbs are dimmable, only specific LED bulbs will dim. This can be avoided through checking the box or description before purchasing. Most manufactures will use either the dimmable or not dimmable symbol, which can be seen below, on the box. Others will simply state whether it is dimmable or not.

Check if your bulbs are dimmable

The most common issue with LED bulbs not dimming is certain bulbs are simply not designed to dim. While almost all Halogen and Incandescent bulbs are dimmable, only specific LED bulbs will dim. This can be avoided through checking the box or description before purchasing. Most manufactures will use either the dimmable or not dimmable symbol, which can be seen below. Others will simply state whether it is dimmable or not.

Identify your Dimmer Module

(Ensure all power is off before altering any electrical equipment or call a qualified electrician)

Most issues are caused by the dimmer module not being compatible with the technology the bulb utilises. There are two main types of dimmer modules, Leading and Trailing edge, which function by trimming the voltage to reduce the power sent to the bulb. 

Leading Edge (Traditional) are currently the most popular dimmer, and what you’re likely to find in an older home, as they’ve been used for many years to dim incandescent and halogen bulbs. The wattage range is often much higher between 60-400w or 250-1000w which means they don’t function with low wattage LED bulbs, causing them to flicker or flash. If your dimmer has a wattage range similar to this you’ll need to use higher wattage bulbs such as Incandescent and Halogen to prevent flashing and flickering. Or you can upgrade your dimmer to an LED Compatible module to use lower wattage bulbs, which last longer and are more efficient. 

Trailing Edge (LED Compatible) are designed to work with modern LED bulbs meaning they are compatible with almost all LED bulbs from reputable manufacturers and found in most new build homes. They operate at a lower wattage threshold however they can still be used to dim traditional bulbs as long as the wattage tolerances are met. If your dimmer is trailing edge you’ll want to use low wattage LED bulbs as using Halogen or Incandescent can cause dimmers to fail.

Upgrade Your Dimmer or Bulbs

As mentioned above different dimmers operate at different wattages, to avoid flickering or failures you’ll want to make sure you’ve got the right bulbs. While Incandescent and Halogen bulbs are usually cheaper they are gradually becoming less common as production has shifted towards longer life LED bulbs. It may be worth considering upgrading your dimmer to an LED module to save money in the longer term as they offer a longer lifetime and lower energy costs. 

 

Meet the wattage Requirements

While LED dimmers operate at a low wattage some bulbs are rated below the threshold such as capsules. These bulbs are usually designed to dimmed in an array for example several low wattage bulbs in one fitting meaning the threshold is met.
