The scale numbers range from LB1 to LB10, where the number is a lower limit for the optical density, i.e. LBn means that OD > n, or <, where T is the transmittance. The minimum scale number for a given laser with a beam diameter of 1 mm depends on the working mode and the wavelength as follows (EN 207:2017):

To give another example, of a more powerful laser—the type that might be used in an outdoor laser show: a 6-watt green (532 nm) laser with a 1.1 milliradian beam divergence is an eye hazard to about 1,600 feet (490 meters), can cause flash blindness to about 8,200 feet (1.5 mi/2.5 km), causes veiling glare to about 36,800 feet (7 mi; 11 km ...
