All rooms with 2 gang 2 way dimmer modules are causing led pendant and wall lights to flicker

[nmh]

Recently done a huge refurbishment of our Victorian semi and builder has done the electrics (could be the issue right there)!

 

We’ve put a lot of dimmer modules in from TLC https://www.tlc-direct.co.uk/Products/SF2182MW.html and the builder has put 2 gang 2 way dimmer modules into rooms that only control the pendent/wall light with one switch. We have Astro and Pooky light fittings and they flicker. 

 

90% of the pendant LED bulbs flicker and in some cases even blow. Builder says dimmer modules just make lights flicker! 

 

We’re using a lot of these pendant kits with the dimmer module above: https://www.pooky.com/products/classic-pendant-light-kit-in-antiqued-brass?gad_source=1&gclid=EAIaIQobChMI2NLrzs_EgwMVQ_N3Ch3GKALLEAQYASABEgKKKvD_BwE 

 

We’ve tried about 3 x variants of LED bulbs and they still flicker. 

 

Interestingly on the ground floor we’re using G&H modules and they have worked without flickering bulbs: https://socketstore.co.uk/product/flat-polished-brass-unlacquered-led-dimmer-3-gang-419434

 

Any ideas what on earth might be going on - we’re at our wits end!!!????

What do you mean by 2 gang 2 way?

Just that one faceplate controls two circuits?

Or do you have some circuits (lights) being controlled by two different switches? If this is the case, it could be a wiring issue in 2 way controls. These are easy to get wrong.

Otherwise it must just be poor quality dimmers

 

Btw the pendant kit is irrelevant, it's the compatibility between dimmer and bulb that is key and unfortunately there's no easy way to know what will work other than try it.

Or use the industry go to  "use a Varilight dimmer" answer

 

If you can take the same bulb as flickers on these dimmers and have them not flicker on another dimmer, you have your answer

Knightsbridge dimmers are poor quality. 
 

I only fit Varilight V pro in general. They work well with 90% plus bulbs/fittings.

Dimmer switch must be LED compatible AND LED bulb must be "dimable"  If either are not, you will get flickering lights.

One faceplate controlling 2 x circuits yes. Could well be poor wiring. I’ll change bulbs to see if it’s the dimmer

OK - TLC Direct - here I come for a Knightsbridge refund! Shame - I liked their matt finish. But meaningless if they don’t work.

Yes - both switch and build are LED dimmable compatible

You could almost certainly keep the plate and just change the internals (module).
