Boost driver for 6v LED

Looking for a high output boost driver, most likely needed to be under 26mm.

So far, the best I can find is the H1-A that can put out 3.5a when modded. But not a fan of the UI it uses…

Ideally, I would like to get something closer to 5a, if such driver exists. But willing to look at others in the 3a and up range

Edit: not looking for a member that has one for sale, but wouldnt be against it lol. I am mostly trying to research what options I have for a project light on its way to me

I guess you have already came across this thread. Buck and Boost Drivers, Testing, Modding, and Discussion (Pic Heavy)
I think the inductor size needed for higher current is whats limiting it for the 20mm size.

Schoki has a new 50W design with new poerful boost chip
Prototypes of v2 board for him and my prototype boards are not delivered yet

Got a link to the post about it? Thats a pretty huge thread to try to sift through.
