Is my VIS 180 the 50 Lumen or 70 Lumen Version?
That is definitely the Vis 180 70 lumen. This is the new packaging that L&amp;M just debuted in late 2014 when the 70 lumen model came out. They sent the new design to the packaging manufacturer just before they got the Vis 180 upgraded to run at 70 lumens, so the white insert says 50 lumens when in fact it's 70 lumens (as shown on the outside sticker there). Another way to double-check is the flash pattern. Does the pulse turn all the way off at its least-bright point or does it only go to about 20% dim? If it goes all the way off, it's the 50 lumen version, if it stays part-way on throughout the cycle, it's the 70 lumen version. You can see a video comparing the old and new flashes on the full Vis 180 review on the bike light testing site I run. 

To clarify on the packaging, all of their lights that are in a series come in the same packaging within that series. So if you buy an Urban 350, the inset has info about the whole Urban line, including the 350, 500, 650, and 800. When you bought the Vis 180, you got info about the Vis 180 and the Vis 180 micro, because they're sold in the same package with a different label on the outside. 

The Cygolite Hotshot puts out much less total light, but has a more focused, intense beam than the Vis 180. The total output of the Vis 180 is much higher. I personally use the Vis 180 as my primary taillight in steady mode, with a secondary (less bright) light in flashing mode. Your proposed setup could work well too. Having two lights is always a good idea!

So, you almost certainly do have a legitimate Vis 180 2014 70 lumen version. One thing to be aware of is that the eBay seller is likely not an authorized reseller, so your warranty may be void: 


  Light &amp; Motion provides warranties against manufacturer defects for 2 year starting from the date of purchase from a Light &amp; Motion Authorized Dealer. While the warranty is non-transferable and does not cover failures from misuse or battery issues beyond one year, damaged lights can usually be repaired for a nominal fee. Proof of purchase required for warranty support.


They have more information specifically about buying from eBay here. I would suggest you inquire as to whether the seller is an authorized dealer &ndash; in my experience, L&amp;M have excellent customer support, but you may be SOL if you bought from an unauthorized source.
