actually cree is owned by a company in North Carolina I believe, it was a group of scientists at North Carolina that developed the Cree. I'm not positive, but I believe the Cree LED itself is made here in the USA, the electronic board it mounts on as well as the rest of the unit are made in China.
yes the Kill Light and others are Chinese, I got the no-name version over a year and a half ago and had posted on several sites...
the Ultrafires are some of the worst mis-labeling of capacity, depending what brand you got, if they were all the same, then most likely what you said as an example, 1000 and then 2000, may be correct, let me give you a for instance, AA Rechargeable batteries from China. I have two high end chargers for AA's, both can measure total capacity and the way you do this is charge completely, and then discharge, which will measure how much charge they had. I bought some 2000 mah batteries from china, the average capacity measured 350mah...so beware, I will guarantee you there isn't such thing as a 5000mah battery and most likely not a 3000mah, think about it, that's 3.0 amp hours...if you know much about batteries, that's hard to get in something the size of these batteries, unless somehow they have their own standard
its just like 14500 batteries, I run them in these small crew XML T7 flashlights I have, I can run AAs, but AAs are 1.2 volts, the 14500's are 3.7 volts and probably around 3-5 times brighter, measuring the 2000mah batteries that are out there, the do just over 1000mah....Chinese not only have no copyright laws, they can also lie besides stealing
