Acebeam TK18 Optic Swap?

[Remembertheslap]

Hi folks,

I want more throw from my Acebeam TK18 (triple osram/carclo optic). It's little brother, the TK16 (which I don't have) throws farther. The specs state this and reviews back it up. I'm wondering if the optic in the TK16 is the same diameter as the TK18 and is the TK16 optic different, more throwy? The lights heads differ by a couple millimetres in diameter, I believe.

Any thoughts?

Ok, I did some more research, I need a 10507 optic.

Any Euro folks here know where to score these in EU / Ireland?
