The head looks like 45mm
Very good seller have bought numerous things from them, and i have received somethings as fast as 8-9 days from them.
Has anyone made an offer on it to see what the lowest they will take?
Not really. Voltage sag is so fast, there wont be any damage.
Nope. The head is definitely 57mm.
Johnnymac are you sure.
VFMaddict did you make an offer or did you buy it?
You are right Johnnymac looks just like the Ultrafire WF-850L
Looks like it has some nice throw, it’s really cheap, I’m going to try it.
Thanks for posting this deal!
Nice!!! One more to add to the collection.
Looking forward to impressions, pics…etc!!
Looks good! Thanks for the heads up!
I wonder how it performs with 4xAAA... Ordered. :)
Yes. I calculated it off of the pics and it converts to 57mm just like they claim.
I should qualify it…as long as they send the same light as in the pics then yes, it’s 57mm. 
You nailed it! It looks exactly like the WF-850L sans magnetic ring.
It does say WF-850L...
3 sold: VFMaddict, FX-32 and me => Sold only to BLF members so far. :)
Where does it say “WF-850L” anywhere on the eBay ad? I must have totally missed it (and still am).
The battery tube is thicker, 26650 compatible.
Hurry up guys!
Oops. I could of sworn I saw that is said that but I guess not. 
Another blf member that ordered out of curiosity, thanks guys you really rock!!!
I bought one too, I’m in Canada so i might get mine much later than everyone else lol. Looking forward to reviews to tide me over till it arrives
