Lux is a measure of light intensity on a surface, not necessarily how much light is needed to produce a usable image. Some cams can do so at 5 lux (or less); others need 100 lux (or more).
Good luck.

And this one:
NMTA = Nothing more to add
LOL
So, when quoted in a camcorders specs it is used to describe the amount of light needed for an adequate image capture?
Panasonic HMC 151E - Canon HV20 - Twoneil 35mm Static Adapter - Nikon f1.4 50mm - Rode Videomic - 2x AudioTechnica ATR35 - Zoom H2 - Steadicam JR - Custom LED Lamp
E2E - edge to edge ( sharpness )
Hard to say. Although a standard is in place in the United States (and perhaps elsewhere) to specify minimum quality standards for light levels, adherence to this standard is not mandatory. Since manufacturers know that consumers want cameras that shoot under low light levels, they are reluctant to use that standard and look inferior to a competitor who is not adhering to the standard. So a manufacturer might say just about anything and it's difficult to tell just what they mean when they quote a particular lux rating.
By the way, "lux" is not an acronym. It's a word.
Good luck.

can someone explain ISO, i dont understand the wikipedia page. is it gain?
If im not mistaken, ISO is a carry over from the days of film photography. In the digital realm, i think it is just a way to measure gain other than by decibals.

Not completely. The light sensitivity of films was standardized, either in ISO/ASA or DIN. If you bought a 100 ISO film, you knew that it was 100 ISO (with tolerances, of course). You knew how fine grained a film was (graininess also depended on exposure and developer, but this is a deeper story).
In the digital realm, it depends on the basic light sensitivity. There is no real standard for much gain has to be used to get a specific ISO value. A sensor with a high base sensitivity can achieve a specific EV at 800 ISO without any gain, while another sensor with a lower base sensitivity needs e.g. 3db to achieve the same and has some noise in the picture.
The ISO value in digital is basically meaningless, and is only used as an equivalence for comparison .... like the 35mm equivalence in lenses (should be field of view instead of focal length in most cases).
MiniDV - tape format used in the HV20 and other digital camcorders since the mid 90's
HDV - High Definition Video - The data stored by HDV camera on MiniDV tapes
dB - Decibels - Used to note energy relating to sound or video, and also how much "gain" is added
FPS - First Person Shooter - Bang Bang! You're dead. See CounterStrike
FPS - Damn, also means Frames Per Second - eg: 30fps NTSC, 24fps Film-like etc
F-stop - Aperture setting on camera lenses. The lower the number (f1.8, f2, f2.8 etc) the more open the iris is and the more light comes in.
