6/9 ◆ Precautions For Use This device should not be used in any type of fluid such as water, oil, organic solvent, etc. When washing is required, IPA should be used. When the LEDs are illuminating, operating current should be decided after considering the ambient maximum temperature. LEDs must be stored to maintain a clean atmosphere. If the LEDs are stored for 3months or more after being shipped from LUMIMICRO, sealed container with a nitrogen atmosphere should be used for storage.
