Modding olight ion?

Hi there. I want to mod an olight ion for a friend. Can anyone give insight on how to open and mod it?

I tried to open mine… I didn’t succeed and don’t want to ruin it.
But man I would love to put some Nichia’s in there !

I think I saw a modded one sell here.

Don’t know about BLF but do know of one that sold here.

I tried reaching out but never got a reply. Sub’d.

Oh right! I asked before and got no response. I just tried posting
