Sorry, did not know you had multi-bulbs. The total however does not quite add up to 60 watts, and one really wants 60 watts when dimmed. There are dimming switches sold as master and slave, so you can have dimming control at both switches, normally an up and down button not a turn device.
Looking inside the last bulb to fail on me, a 9 watt TCP

not all the chips are the same, some are low colour temperature and some are high colour temperature, and by varying how much power goes to each it can give a whiter or redder light. The early bulbs before the smart bulb hit the scene would only dim the whiter LED's so it seems as if the bulb is getting redder as it dims, giving an ambiance similar to a tungsten bulb. It seems these were very popular in the USA, but not used so much here.
When the smart bulb hit the scene, and as they came down in price, with GU10 bulbs at around £5, there was not that much of a sale for the bulbs which went redder, so they have disappeared.
Varilight Multi-Point slave dimmer switches must be used with the Multi-Point master and will not work on their own. Slaves allow 2 way or even 3 way dimming. This means you could dim the same light from multiple locations.
The S-link is wired similar to the com with these switches,
but it is not a com, and the switches need to be wired as master and slaves,
other makes have different ways to wire them, no longer does one wiring diagram suit all. I don't know if you can get smart dimmer switches? I know we use smart lights in the kitchen, so we can turn them on without putting flour covered fingers on the light switch, on/off and dimming even colour change of counter lights is voice commands.
I have become lazy in my old age, at ½ hour before sunset the living room main lights switch on, and using voice control it does not matter if lights on lighting circuit or plugged in, hey Google turn off living room lights turns them all off.
Wife has got use to automation, it's hey Eric make the coffee. Seems the world has moved on. Our grandchildren will be asking "What's a dimmer switch" they will likely think it's when we get another power cut as the grid can't take the load.
My old kitchen had a 65 watt fluorescent lamp, latter a 24 watt LED tube replaced it, son now has the house, and now 14 GU10 down lights, at 4.2 watt each that's 58.8 watt, are we going backwards?
