Lux
is a measure of illumination on a surface (lumens per
square metre) and the values given in the diagrams show
the peak intensity at the beam centre at distances of
1, 2, 3 and 4 metres from the lamp.
The beams are drawn
at the end angle where the intensity is 50% of the intensity
at the centre. The lux values in the diagrams are reproduced
from lamp manufacturers' data.
