These are the same Asian vendors who proudly sell "6000 mAh" 18650 cell batteries, even though no battery chemistry on Earth could get you that energy density.

These are the same Asian vendors who proudly sell "6000 mAh" 18650 cell batteries, even though no battery chemistry on Earth could get you that energy density. They know it's much less than 2000 lumen, but they don't give a crap about the factual accuracy of the specs. And I think most people who are savvy enough to buy from these sites quickly catch up and learn to divide by 2 or 4 or 10. Amazon, OTOH, has a bigger problem in this regard since everyone buys stuff there. Fortunately Amazon has a much better reviews/ratings system.
