lux=measured light intensity in Lux (given as a real number) — optional
Specifies the measured light intensity in Lux — if a higher accuracy is needed.
Puts the light intensity found at a certain part of the dive spot (e.g. the habitat of a sessile animal) into brackets. Allowed values are: undetermined, sunny, half-shadow, shadow, no-light (e.g. in a cave). As an attribute it is possible to specify the exact, measured value of the light intensity in Lux, given as a real number.

<!-- sunny dive spot, no shadows given --> <lightintensity>1</lightintensity>
<!-- sunny dive spot, light intensity measured and given --> <lightintensity lux="5000.0">1</lightintensity>
