But in my experience, it's most common with 12V MR16 / GU5.3, MR11 or G4 low voltage light bulbs. This can potentially happen with any light bulb or fitting. Other brands, and in very rare cases the Philips bulbs, may require a 12V LED transformer to work well. However, our Philips MR16 LED 7W bulbs have some smarts built into them, so they still work with old transformers, even at this lower load. Most old transformers have a stated output range of 20W to 50W. Apart from the dimmer issue already discussed above, this can also be due to: Whether or not a dimmer is involved, low voltage lights such as 12V MR16's can sometimes flicker. 3) LED Downlight Flickering (12V Lighting Flicker - Transformer or Connection)
What kind of dimmer for led lights to prevent flickering upgrade#
As such, they are a quick job for an electrician to upgrade or replace. Lighting dimmers typically sit behind the switch plate as pictured here. Alternatively, you may be able to add a 'load correction device' to existing Clipsal dimmers or a 'load bypass device' for the Diginet range. If necessary, upgrade to an LED optimised dimmer such as our rotary LED dimmer or LED dimmer with on/off switch.
An underloaded dimmer is most often the cause of this. 2) Incompatible or Under-Loaded LED DimmersĪfter upgrading to LED lights you may experience flickering or flashing from an old dimmer switch.
Most of our lighting products carry a 3 or 5 year warranty - and are expected to last much longer than that.īuying quality brands from a reputable retailer is often the quickest way to eliminate flickering LED lights. As an example, we offer a minimum 2 year warranty on all the LED lights that we sell.
These include high frequency flicker and intermittent flicker from the electricity grid. Old fashioned fluorescent tubes and low voltage halogen downlights also have issues with flickering.įinally, there are some lesser-known flickering phenomena. A common complaint is LED downlight flickering.īut it's worth remembering that flickering is not the exclusive domain of modern LED lights. In other cases, we encounter strobing or blinking related to transformers or the dimming of LEDs. Sometimes flickering is caused by low quality LED lights. There are many potential causes of flickering lights.
