scottr: Suspect with all the light going down as opposed to everywhere else that a lower amount of lumens are OK.

Have come across these, 15w at 120 lumens, dimmable, and will fit the current downlight hole without any adapters or re-cutting of the whole.

http://ledx.co.nz/product/15w-led-downlight-120/

Only 22.90 so I might grab one, give it a blast, and if all goes well potentially grab a few more. Anyone come across these or this company in their travels?


@scottr Check what type of dimmer you need. As older dimmers tend to be leading edge. While LEDs and other lights with drivers tend to require trailing edge dimmers. Also remove the bulbs from the other lights on the dimmer while testing. As having a filament lamp connected to the dimmer helps the dimmer to work better with LEDs.

@Ardewood can you recommend a specific dimmer that works well with LEDs? I have four in my office, my electrician tried two but none worked well.

Matching them up is something that only experiance will tell you. Newer dimmers have a microcontroller in them and may even need a certain version of firmware to work properly with some lights and have the right amount of extra brightness added at power on to actually get the power supplies to start up.

 

I have tried many and none have provided an adiquite ability to turn on at almost nothing and bring it up if needed. If you have clipsal style plates there are way more options to choose from than if you have the PDL wall plates.

I've had a different experience after also trying many.  No problems with Philips dimmable lamps and LEDLux Clipsal type dimmer inserts.  Strangely perhaps, the Philips bulbs work better than the LEDLux brand bulbs (3 x 14w E27s on the circuit) I've got using the LEDLux brand dimmer (even with adjustment of the dimmer trim-pot, I can't get minimum brightness of the LEDLux lamps down to close to zero).

 

Philips have added a "gold" dimmable logo/icon to their lamp range sold in Europe:

 

 

That seems like a very good idea in principle - whether it works in practice is another matter.

 

It would be a safer bet to go with the gold logo - if they're available here - regardless of dimmer brand.

 

They have PDFs available of tests conducted of an assortment of dimmers sold in the the European market with their lamps.  Probably not a hell of a lot of use here - as the dimmer models might be unavailable.  But reading that gives a pretty good indication of the kind of mess the dimmer/lamp compatibility thing has become.

I’ll be replacing the current dimmer (20 years old and 1000w) with either a fibaro or aeotec one. They’re both universal so should be ok.

It’ll be running 6 lights so hopefully that’s enough load for it to operate successfully.

I was leaning towards the fibaro one as it supports a seperate on/up and off/down button configuration. Just weighing up whether that’s worth the extra 40 or so bucks

Can't edit the above post.  I was at my local Mitre 10 Mega who stock quite a few Philips dimmable LEDS, none had the "gold" dimmer icon as above, only the plain/silver icon.
