Dimmer Dilemmas

General Discussion

hi
new to this so sorry if this is repeated

I have purchased the fibaro dimmer 2 and RGBW dimmer modules, both working as expected

but as i see it the dimmer2 is for 240v and the RGBW is for 12/24 v operation

The dimmer2 with bypass connected to 11 240v5w dimmable LEDs works fine as a main light but the minimum brightness is at about 25% (on a scale of 1 to 100) it is set up at 1 to 100% and i think this is a physics of the bulb needing a minimum voltage to work the drivers,
The RGBW connected to a rgbw strip light has a minimum brightness of about 5%, again this stands to reason as the dimming is being applied after the driver/transformer, also the dimming is smoother,

Moving on to my practical application, I want to use spot lights for mood lighting, so based on the above i would fit a single high power driver/transformer then use dimmable led spotlights, I have struggled to find any in GU10 fittings, but have found loads with good reviews in GU5.3 size,

Am i correct that the only way to control and dim these after the transformer would be with the RGBW controller using just one channel? I like how the physical switch works on the dimmer2, on the RGBW it just turns the channel on and off, also the app is set up foe multi channel and not single channel,

are there any other makes that with work with ST that are 12/24v only?emphasized text

small update

after reading


I have set up the RGBW as a 4 channel 12 controller and this works well, I can turn on/off each channel with a physical switch as required by the missus, this means i can split up the 20 led spotlights into 4 groups and only buy the 1 controller,

furthermore
there are tiles on the app to give you different colours, in the code you can change the value and name of these to create several scenes, I changed pink renamed it scene1 and set the W channel to 50% (0-255 in the code)

here is the bit of code i changed

to change the values of the channels
private getPresetColors() {
return [
[name: “black”, red: 0, green: 0, blue: 0, white: 0 ],
[name: “white”, red: 255, green: 255, blue: 255, white: 255 ],
[name: “red”, red: 255, green: 0, blue: 0, white: 0 ],
[name: “green”, red: 0, green: 255, blue: 0, white: 0 ],
[name: “blue”, red: 0, green: 0, blue: 255, white: 0 ],
[name: “cyan”, red: 0, green: 255, blue: 255, white: 0 ],
[name: “magenta”, red: 255, green: 0, blue: 64, white: 0 ],
[name: “orange”, red: 255, green: 102, blue: 0, white: 0 ],
[name: “purple”, red: 170, green: 0, blue: 255, white: 0 ],
[name: “yellow”, red: 255, green: 160, blue: 0, white: 0 ],
[name: “pink”, red: 255, green: 50, blue: 204, white: 200 ],
[name: “coldWhite”, red: 255, green: 255, blue: 255, white: 0 ],
[name: “warmWhite”, red: 0, green: 0, blue: 0, white: 255 ]
