I see they did add the A6 to their spreadsheet: "entry level, uni-body, black anodizing, TIR, ..." TIR is a little interesting.
Mostly it seems a step down from the current lights (lower CRI, fewer modes, lower max, higher min, . . .). I guess that is what they mean by "entry level".
Yeah, I never understood why they would try to get into a lower-end market while still trying to sell it at a fairly high price. Doesn't seem like a good strategy. My bet is that they already did the design and manufacturing of the A6 some time ago, and now they want to sell off the supply.
From what I have gathered on-line, Zebralight is a Chinese company owned by two family members, with all design and manufacturing done in China. They (used to) have a US warehouse and company registered in Texas, with just a handful (or less) employees. I'd guess the owners have got into another business, and are winding down the flashlight operations. It looks like they've been doing that for at least a year, with perhaps the exception of the A6 (which is something they planned a long time ago).
Or, I could be totally wrong, and they are just selling off old models before introducing a brand-new line-up of lights in the new year. Doesn't explain them closing up shop in the US, while only selling to the US in the new year. That is more easily explained by selling off remaining inventory. Though, I'm still not sure why they wouldn't sell world-wide, since they already know how to do that. For me, that's the most perplexing part.
Zebralight was always a niche company. Maybe they've saturated their market niche, and are just not seeing any growth opportunities. 5 years ago, there were a lot less budget flashlight options. Now, you can get a kick-*** light for half the price of a Zebralight. That's tough to compete against. The budget offerings aren't as nice as zebralights, but the vast majority of potential customers don't care.
