We have ceiling-mounted LED downlights throughout our six-year-old house. When we moved in, I got an electrician to install dimmers on some of the sets of lights. I was a bit disappointed when he said (as he was installing the dimmers) that the lights couldn’t be dimmed all the way down. They dim to only about half-way to being off.

 

I have just bought (from Lighting Plus) an LED pendant light bar to go above our dining table. I bought one that is said to be dimmable. I am going to do the physical mounting then get a sparkie to come and do the electrical connection and the dimmer. The instructions that come with the light fitting say “Suitable for dimming with most LED-friendly dimmers”.

 

I’d be grateful if anyone can advise or comment on whether I’m likely to be disappointed again that the light will only be able to be dimmed down to a (still fairly bright) limit i.e. not able to be dimmed quite low or right down. I’m thinking there are differing types of LEDs and differing types of dimmers.

Can't speak about other brands, I personally use visionary LED downlights as recommended by other members, they are great. I use Aeotec Nano Dimmers with them (for home automation), the lowest I could get it down to is about 20%, any lower the lights simply switch off.

Dimming LED drivers by messing with their power supply with a phase angle dimmer that doesnt even have a neutral connection is always going to be on the miss side of hit and miss.

 

Some sparkies have moved on from this abortion of LED control to dali based stuff but the pricing tends to scare most homeowners off.

I got dimmable LED downlights, but after months of trying options I gave up and got rid of the dimmers. If you need dimmable LEDs suggest you buy a system that is made to work together, ideally with the LED and dimmer the same brand, or something that's well known to work well.

Get your sparky to bring a selection of dimmers that fit the brand of switch you are using, and then just go through them until you get the best results.

I've swapped my downlights to the Halcyon brand ones (stocked at all the electrical wholesalers), and have found them really good with the Shelly Dimmers. Got them on trailing edge dimming, and did the 'calibration' in the Shelly UI - no idea what it's calibrating, but you just hit a button and away it goes.

 

Before that, I was getting some pretty bad flickering at low light levels with the disgustingly cheap LEDs that had been installed previously.

 

I would still consider the Halcyon ones very cheap too at only $20-odd each (wholesale), but they seem to work very well in my circumstance.

Perhaps it comes down to quality of the downlight too? The ones in my place I built ~5 years ago cost quite a lot (when I shopped around the price seemed extreme! But my sparky didn't mess around with cheap stuff and I was happy to pay), but dim low enough that I wouldn't want to be reading text. My switches are PDL / Clipsal and i'm pretty sure the dimmer was just a standard unit from PDL too. I don't know what brand / model my downlights are.
