<s>[INST] Care needs to be taken not to fog up my EL Compact LED flashlight with moisture from my mouth or breath. Generally, I do not have this issue with EL lamps other than my most recent acquisition. 

While this issue is not severe, it is noticeable. The fluorescence is present but erroneous behavior of light such as what can be seen in moisture promoting dramatic unbalances inside the electrolyte. 

Could you explain why this issue is a matter of concern?[/INST]
