Well, that was an interesting day
I have mixed feelings about the ClickFlow connectors. I like the ease with which they can be connected/disconnected, but there is no strain relief. A 1.5mm is snug, but not tight and a 1.0mm is obviously even looser. I ended up using cable ties squeezed through a couple of slots in the body which worked nicely. They are a bit on the small side and one of the connections (the one acting as ceiling rose) was very tight.
As I say, mixed feelings. Do I think they saved me any time? Possibly, but I'm not convinced it's enough to switch from my usual method which is Wago boxes and Wago lighting boxes, with the lighting connectors.
The other gripe I have is I needed two different screwdrivers when terminating the plug part that connects to the lamp. And I just couldn't find a driver that fitted nicely and didn't keep popping out of the screws.
I'd be interested in hearing other peoples experiences and advice
