Fluorescent lights and sunlight both emit ultraviolet light at the erasure wavelength. Leaving a UV erasable
device’s window uncovered could cause, over time, the devices memory cells to become erased. The era-
sure time for a fluorescent light is about three years. While sunlight requires only about one week. To pre-
vent the memory cells from losing data an opaque label should be placed over the erasure window.
