The installation was a breeze. When you have the dial once separated from the dimmer, which is added quite difficult (rubber gloves help here thanks to better adhesion!), Everything works more easily. The port name, the usual. L = conductor (usually black wire) and the shaft with the arrow does not live cables.
What I find really awesome is the adjustability of the maximum brightness. For this purpose is located on the side of the dimmer (offset inwards) a set screw that can be adjusted with a small screwdriver. Thus, even if many dimming LEDs did not work right away, it has to adjust a bit but then on ALL LEDs work in the house.
Also, the dimmer can handle all loads, even under 20W! The smallest I've attached are 3x 3W and even there everything is working fine.
This product is a 5 star deserves, here can not keep up even much more expensive dimmers branded manufacturers in terms of compatibility and settings!
keep it up!
