I will need to buy a dimmer switch module and four bulbs
I've been thinking about this recently and came to the conclusion that there is no point buying dimmer switches/modules.
If you have a normal light switch, just buy smart bulbs. It's the future but also avoids the risk of flickering LED bulbs (when even recommended LED dimmers seem to suffer from this sometimes).
I have this problem at the moment - 5 bulbs, G9 too, I have found one brand/type of smart G9 bulb, otherwise there aren't any, possibly for a good reason...
Decent dimmer switches and modules are pricey too to be fair.
