Will my setup work?

Hey guys,

I’m working on a project and would like to know if this setup would work. I’m concerned about the optic holder not accommodating the MCPCB.

The LED will be a LH351D on a 20mm MCPCB. This is the one on Mtn here.

Alternatively, I am considering using this one from Kaidomain here.

The optic is a Carclo 10003/15.

The optic holder is Carclo 10734 lens holder.

Also, I’m assuming I can’t use a 16mm MCPCB with this lens holder?

Will either of these MCPCBs work with the lens and lens holder I’ve outlined? I don’t see these commonly used, so I’m not sure myself. I’d appreciate any input. Thanks!
