First of all, I may very well be ignorant, so bear with me. I have been reading about the pitfalls of dimming 220V LEDs on the forum, and I was wondering how the dimming actually worked for the RGBW module. The Fibaro FGD211 dimmer is a leading edge pulse dimmer, but is that how the RGBW module works, or does it instead modulate either voltage or current?

In practice, let's say I connected 1m and 4m of the same RGBW strip in parallel to the same RGBW module -- when dimming, would the 1m and 4 m strips be equally bright (per LED)?

(The advantage of connecting LED strips in parallel would be e.g. not having to sync different modules, and it's not always practical to use one continuous or spliced strip.)
