I don’t have either of those lights so I can’t compare it to the size. But here’s a few common ones to compare it to.
Rey makes a great light! They’re beautiful, well priced, have excellent drivers, and he fully stands behind his product in ways I don’t see with other manufacturers, even Hank. (The MKII had a forward clicky switch. Enough people said they didn’t care for it, that he now offers a replacement reverse clicky switch for $1. And it’s not just the switch, it’s the full tail cap).
You cannot go wrong with a Reylight!
