Question about a light

I saw this looking through tomtop lights and was wondering is this a C8 (me newb)? The price seems good & reasonable to me. Is there anything I should know before I think about purchasing it? Sorry for the weird questions. Just dont want to be hoodwinked.

Looks to me like a re-spin of the smaller Ultrafire C2. This one in gray typeIII was my first ultrafire light 3-4 years ago. I had to reflow solder on the switch, but its been fine since. I have updated the gaskets to make it water submersible and my kids use it as a bathtub/pool toy. Just the other week the dome fell off the XRE so its in need of an overhaul. Its a really nice light, well worth the ~$18 I paid for it.

Thanks for the info does that model have a screw in or drop-in pill?

what are the differences of the C2 and the C8? Are both upgradable and modible? Is one better then the other? Any info to help would be help full. I dont currently own a light with a reflector any bigger than a p60 drop-in.

Thanks
