My comment about Lux ratings basically meant that if they don't mention the rating, then it is very likely that the unit has very poor light sensitivity. I wouldn't want to buy a camera that was in infrared mode 90% of the time, becuase the Lux rating was so low the camera only worked in color in broad daylight.
Hopefully someone with more money (or less of a skinflint) than me, will buy one and give us a report. It looks like a nice unit.
