For preserving the aesthetical outlook, and maintaining the maximum

time to time. Since the light is operated by solar energy, keeping the solar
panel clean & free of dust is key-essential to ensure its efficiency, and
maximize discharging time. Please follow the instructions below when
cleaning your light:
1.
Please always use a suitable, soft, and damp towel for cleaning the solar
panel
2.
Apply the towel with higher water content for the first time at each
cleaning procedure to remove the majority of dust preferably with one
movement.

After washing the towel in continuous water stream to remove the
accumulated dust, squeeze the water out of the towel, and remove the
remainder of dust with the towel gently from the surface of the solar
panel if necessary. Care to avoid scratching the surface of the solar
panel.

If you observe scaling, or other accumulated dirt on the surface of the
solar panel, please only use a chemical or natural enzymatic based
agent for cleaning which is recommended for solar panel cleaning by
its manufacturer.

Cleaning of the plastic and metal parts of the light body can be executed
easily, but attention is needed to avoid scratching of the surfaces.ű6)

In case of poor daytime light conditions (continuously overcast, cloudy
weather throughout multiple days, low sunshine hours in wintertime)
the light recognizes low battery voltage, and switches off automatically to
prevent the battery from damage, and to maximize the life cycle of the
battery. Whenever the charge of the battery is sufficient for safe operation,
the light turns on in the dark. The process is automatic, interaction by the
user is prohibited. Besides that, the light applies an eco-mode when the
battery level is low but sufficient for operation. In this case the light will
shine at a dimmed mode.
