I'll jump in if that's OK.
The bodies and reflectors are built in the Czech Republic. Two very similar (actually more than the two but I'll keep it simple here) lights exist with very similar designations, the LEMAX 70---the topic here and distributed by LEMAX, generally in Europe and the XeRay XV-LX70, distributed by XeVision out of Ogden, Utah, USA.
The two are virtually identical with some possible exceptions which I'll not address here. "Dan" from XeRay covered them well in another thread, possibly the one started by bulbmogul though I'm not sure. Dan offers an "upgrade" which permits end user changing of the bulb should that ever become needed. Dan also spoke of a possible increase in output to a level of 80-85 watts identified in a thread I started a week or so ago, that project having a target light named the "Ultra" though final confirmation of that name not completed.
The lights sold by LEMAX last year were offered for a one-time limited period at a discount, I believe 30%. I don't believe that offer is still valid though I doubt it.
I really don't want to go much further with this distinction since it was discussed in some greater detail by Dan at XeRay. Now, who has what I'm really not quite sure. I know bulbmogul posed the question about the LEMAX70 Superpower as I believe he has one and, I don't think anyone came forward. Some folks here tend to want not to "show their hand" of specific light ownership so to speak and remain silent. Others are proud of their individual collections and so state. Whatever floats your boat as is said.
Hope I didn't muddy the waters.....
