5. Determine the correct brightness
To prevent any damage, sensitive exhibits should not be illuminated unnecessarily brightly. When specifying suitable showcase luminaires, it is therefore particularly important to ensure they are infinitely dimmable. At the lowest dimming level, an illuminance of <50lx should be possible even at a short distance of 0.30m. As well as infinitely variable dimming, ERCO neutral density filters ensure that the illuminance can be further reduced so that your exhibits are only illuminated as brightly as needed.
