I’m looking for up to 30mm plain and stripe/oval lens that will fit on XHP50.2. It has bit bigger dome, like almost 6mm diameter. Ledil doesn’t list Leila/Emily/Veronica as 50.2 compatible, Carclo has some, but I think PMMA is better but efficiency is so-so (PC?). Do you think that Yajiamei like those are ok:
