One lumen per square meter, also known as a lux, is a measure of illuminance that quantifies how much light is received on a surface. It represents the intensity of light that is distributed over a given area. Specifically, one lux is equivalent to one lumen of light spread evenly over one square meter of that surface. This measurement is commonly used to assess lighting levels in various environments.
Technically, the answer is "un-defined" or un-answerable. They define 2 different types of measurement.A "meter" is a measurement of length, while a square meter is a measurement of area.Think of it in terms of the shape of a square that is 1 meter x 1 meter x 1 meter x 1 meter. You can define the perimeter length (which is what you might be asking for), and that = 4 meters (each of the sides of the square added together). The area of the square is 1 square meter, which you get by multiplying 2 sides of the square together, which in this case is 1 meter multiplied by 1 meter = 1 sq/meter.
Light intensity or irradiance
A square 1 meter long and 1 meter wide is 1 square meter. 1 square meter equals 1.19599 square yards 1 square meter equals 10.76391 square feet
Half Square meter is twice as big as half a meter square.
One square meter is defined as the area of a square with sides that are each one meter long. Therefore, 1 meter is simply a linear measurement and does not directly convert to square meters. However, if you consider a square that is 1 meter by 1 meter, it encompasses an area of 1 square meter.
Lux and lumen are both units related to light, but they measure different aspects. Lumen measures the total quantity of visible light emitted by a source, while lux measures illuminance, or how much light falls on a surface area. Specifically, 1 lux is equal to 1 lumen per square meter. Therefore, the number of lux in a lumen depends on the area over which the light is distributed.
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.

Light Level or Illuminance, is the total luminous flux incident on a surface, per unit area. The work plane is where the most important tasks in the room or space are performed.Measuring Units Light Level - IlluminanceIllumenance is measured in foot candles (ftcd, fc, fcd) (or lux in the metric SI system). A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter. 1 lux = 0.0929 foot candle = 1 lumen /sq meter = 0.0001 phot1 ftcd = 1 lux / 10.7521 lumen/sq ft = 1 foot candle = 1x104 lux = 1 phot
Apparently Lumen's :S
The second.I see the "second" as a measure of time, not light.LUX, Lumen or Candela do ring a bell and something like watt per square meter..Yes the S.I. unit measure of light is a limen (lm) .lumen (lm)The SI derived unit for measuring the luminous flux of light being produced by a light source or received by a surface. The luminous intensity of a light source is measured in candela. One lumen represents the total flux of light emitted, equal to the intensity in candela multiplied by the solid angle in steradians (1/(4pi) of a sphere) into which the light is emitted. Thus the total flux of a one-candela light, if the light is emitted uniformly in all directions, is 4pi lumen.
Light intensity or irradiance
That's not a special kind of light - you can do that with any light. The power per area (e.g., watts per square meter is a measure of INTENSITY.
