What if I drop the lamp or the solar panel in a pool of water?

Both the lamp and the solar panel are reasonably water-sealed, with the goal of preventing damage from rain or accidents such as these. A brief accident such as dropping the lamp or solar panel in a fresh-water lake or river will not harm either device, as long as it is not submerged and is promptly removed from the water.

However, Sun King products are not designed to be used in salty environments: Salty seawater is corrosive to metals. Exposing the lamp or solar panel to excessive amounts of salt water or salt spray will cause the electrical connectors to rust.

Sun King products should not be left to sit on the shelf unused for more than one year in warm climates, and no more than two years in controlled-climate storage (below 25°C).

If lamps are left in storage for more than one year, a small but mounting percentage of the batteries will become completely discharged, rendering the lamp unusable.

How can I tell when the Sun King Pro is finished charging?

The best way to check the battery status is to turn on the lamp, and view the LCD display, which will indicate the number of hours of light remaining: A fully charged battery will offer six or more hours of light time in “Turbo” (brightest) mode.

During charging, when the Sun King Pro’s battery is nearing a full charge, charging will be intermittently interrupted. It can therefore be assumed that if the LCD display indicating charging strength has turned off (permanently or intermittently) under sunny conditions, the battery is full. Unfortunately, the lack of a definitive “fully charged” indication can be confusing, so we are working on a better display mechanism to indicate a fully-charged state.
