OK yeah don’t know what I was thinking :person_facepalming: I de-soldered it now, he contact board is actually nearly 24mm and the shelf is about 1mm wide, and only 2.3mm of room under the shelf.

.
So it looks like the star with 7135 is the best way to go, not sure what kind of emitter it would use though it looks like the emitter wires get attached outside (not through the emitter base)

Maybe it would be easier to use this one, already has an emitter (warm white!):
It doesn’t say it can expand to 700mA but there’s the place to add a 7135 at 6:00, the question was asked (by two BLF members) in the discussion, but no one answered.

Not sure what kind of LED that is either.

“Everything you can expect from a cheap generic emitter and an AMC7135 driver. I was surprised by the tint, very nice (if you like neutral/warm tints)”

.

Or I could use something like these and just fit the 1050mA or 1400mA driver:
