I purchased a chandelier from Aliexpress (China) that came with bi pin G9 LED bulbs (3W equivalent) (pic attached). I asked the seller if this was dimmable and he said NO the bulbs are not dimmable. Apparently China uses cheap non-dimmable bulbs. But the seller told me I could purchase dimmable G9 bulbs and pair them with a dimmer switch and it would work. When I use the bulbs the factory sent me and hook it up to a normal switch (no dimmer), the chandelier works fine. When I replace those bulbs with dimmable G9s, I hear a loud pop and the light doesnt work. I have not tried hooking it up to a dimmer yet, but what is going on?? Is the pop because I am not using a dimmer with the G9 bulbs? Should that matter? Anyone have a clue and how I might solve my problem to use dimmable G9s with a Lutron dimmer. If so, what Lutron dimmer should I use? Meastro or Diva or something else that can handle the low output of the LEDs when dimmed? Update, I ordered a different G9 dimmable bulb (dimmable) and with a regular switch it came on (no pop) but at a very very faint level. Will this change if I add a Lutron dimmer? Thanks.

Maybe the chandelier has been made to accommodate g4 bulbs, and been fitted with 240V g4's!🤔, eg (these are 5W not 3W):
in which case, is the chandelier safe to use? I suppose 4mm pin spacing is OK?
if so it may be difficult to obtain dimmable bulbs for it!

Edit - these mains G4's are available in UK on Amazon I see (but all un-dimmable)

I tried the bulbs below and they caused the loud pop I described. There is no transformer on this chandelier. Just wires for each arm with connects to two bulbs.

Sounds live you've put mains onto a 12v fitting, check if there is a integrated transformer in the base
There is no transformer. Just wires from each arm on the chandelier which I have bound all together and hooked up to the main. These G4's from China work directly with mains, no transformer. Yet other G4 bulbs I buy which are dimmable do not work. They create a loud pop and the dimmer gets fried.
 
Are you using the correct voltage G9 lamps?
How do I know what the correct voltage is? I asked the Chinese factory they said they bulbs are 3W equivalents. They hook up directly to the mains. No transformer. They work fine. When I put in dimmable G4 they create a loud pop and if I have a dimmer attached it gets fried but the chandelier is fine, I can refit the original bulbs from China and it works fine. But I have to put on a regular plain switch, no dimmer.
