I've got an Akarui Dry Cabinet 40L. When I was shopping for this dry cabinet, I was told that the cabinet will auto power-cut when the humidity is within the 45-55 range. I understand that it has to be switched on 24/7 but the red power light is on most of the time, so is it right to see the light? Or what should I be expecting? Then the analog hygrometer is showing below 40, usually 30-35. Will this affect my camera,lenses? Thank you in advance.
