Update for the ATC version of the light, sold
on ebay and
on Amazon:
Mine arrived in three business days, since ATC is a US seller. The light and accessories came in a plain white box with a short instruction sheet/warranty card.
On the bad side, the light no longer has mode memory: it always comes on in High, and you have to cycle through Hi->Med->Lo->Flash->SOS to turn it off. The O-rings don't have the little pull tab. And the charger still has no LED to indicate charging status.
On the good side, the battery indicator is now functional! The button turns red when the battery is almost gone, and it's relative to the mode: if it goes red on high beam, turn it to medium or low and it'll be green for a while longer.
Also on the good side, the battery case is still the good kind, with two straps; the battery itself is encased in rubber, not just shrinkwrapped; the connectors have the screw-on shield and O-ring so they won't pull out when riding; the reflector is still OP; and the combination of the light cord and the battery cord is long enough to reach all the way to your jersey's back pocket or a lumbar pack.
I got about 3:30 out of a fully-charged battery pack on high, with an ambient temperature of 65 degrees, which exceeds the claim of 3 hours. There is a perceptible difference between Hi->Med->Lo. The light head gets very hot in high mode, like "too hot to hold".
The LED tint is pretty good: it's cool white, but not outrageously so, with no blatant bluish cast or massive green rings. I put a very slight amber filter on it to make it more neutral, but it's much better than most cheap LED flashlights.
Verdict: This seems to be one of the better versions of this light. It worked fine out of the box, the battery exceeded claimed run time (though it'll decrease in cold conditions), and a US seller with a (claimed) one-year warranty is a bonus.
