WebThe most important factor in determining even illumination is the max/min ratio. We can see that the HID source has a value of 10.8, compared to the LED source value of 2.13. This calculation confirms that an LED source similar in output to an HID source is capable of producing much more even illumination. But this looks even better in color: WebLighting levels are defined for types of sports and usage to ensure good visual conditions for players, referees, and spectators.: For soccer: from 75 lux for training (also 200 lux in between) to 500 lux for an official match.
