Some work with both leading and trailing edge.
With LEDs, you need to see what the manufacturer specifies, as there's a lot of different designs available.
Hi all,
I've got some 240v down lights that come with a 240 -> 12v trailing edge transformer. Would I be able to replace the transformer with a leading edge one without causing any issues?
Thanks

I've spoken with the manufacturer and said if a leading edge is used it may cause flickering.
So does the Dimmable Driver (240 -> 12v) matter? Can I use the existing driver, and try it with a leading edge dimmer?

The short answer is " you cant do that there here. "
Essentially L/E has maximum 240 V output,
whilst T/E has maximum of 12 V output.
Also need L/E for 240 V motor control. (exhaust fan.)

Just wondering if I should replace the LED drivers with these, as they mention compatability with both leading/trailing edge dimmers?
It depends on the dimmer you intend to use because the item desciption specifies paticular types & brands of dimmers which are compatable.
Given you already have the trailing edge transformers with the lamps (and assuming they are dimmable) why not just use a trailing edge dimmer to suit them, which would probably be cheaper than replacing all the transformers... depending how many you have of course.Compatible to HPM leading edge & Clipsal Universal and Clipsal Trailing edge Dimmers
Ill be using a z-wave dimmer that's designed for leading edge, hence the reason for changing trailing to leading edge.
