Every lamp is designed by its manufacturer to have a certain intensity of light on a certain pre-determined surface, a lamp beam. A 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 the distances of 1, 2, 3, and 4 metres from the lamp. The beams are drawn at the angle where the intensity is 50% of the intensity at th centre. For example, the LED M/M MR4, 8W lamp at 14 degrees beam, at the distance of 1 metre gives 2179 lux and on a 0.29m diametre on the surface, etc. This does not mean that there is no light/lux besides this cone of light; the spot is focused on these measurements(as the manufacturers specify). The lux values in the diagrams below are reproduced from the lamp manufacturers’ data.
