Oh I wish I did, all I can say is the worse bulbs in my house were the G9 bulbs, it seems the smaller the bulb the greater the problem, these two bulbs
are both G9, the smaller one flickered, the larger one did not, inside the larger one I found a large smoothing capacitor, which explains why the large one does not flicker.
However if I fit one of the large bulbs, or one quartz halogen bulb, the other 4 small LED bulbs don't flicker, and the small bulbs with a mechanical switch rather than electronic switch don't flicker, and the electronic switch one can hear a relay working inside the switch, it's not solid state switching.
The switch manufacturer does a chart to say what bulbs work
this has clearly been updated, it now says
Recommendations: We advise our customers to use Dimmable LED bulbs ONLY and a minimum of 5 Watts per bulb recommended.
note the minimum of 5 Watts per
bulb, not just total, and finding a G9 bulb 5 watt or over which will fit inside the same glass covers used with quartz bulbs seems impossible.
So in real terms the chandelier looks completely different with LED bulbs fitted.
But we should not dim quartz halogen bulbs, it reduces their life, we could not dim CFL (compact fluorescent lamps) so until the LED we could not dim lights once the old tungsten bulbs were withdrawn. However I was not trying to dim, only switch with electronic neutral less switches, and still had problems.
So today I simply don't try, I use smart bulbs if I want to dim lights, so all built into the bulb. Some dimming switches do seem to have a good name for no flicker, but even with simple mechanical switches I have had flicker, and it seems not related to price.
However in the main I dim lights for ambulance, and so want to also reduce colour temperature, and a dimmer switch can't do that, so basically it seems the day of the dimmer switch has gone.
