Hello and :welcome:
I'm really not sure but they look pretty good and the large model clams a MC-E with 600lms but looks can be deceiving. They do not describe the finish hardness Type II or III and at those prices I would like to know the lens material to, maybe someone can comment if they own one?
If it was me though I would rather buy one of the light's more discussed here on CPF so you know the in's and out's even before you buy it, plus like I said at those prices you can order some pretty good light's that are a little more well explored.
