To recharge your Pina Pro lamp, plug the provided charging base into an outlet and place the lamp on the base. The button on the base will glow red while charging and turn off once the charging cycle is complete. A full charge takes around 6 hours. The lamp should be removed from the charging cradle when the battery is fully charged. The versions with a metal leaf finish are handmade and protected by a clear varnish. We recommend cleaning using only a soft, dry cloth. The use of aggressive cleaning agents or abrasive cloths, or any accidental knocks, may damage the delicate leaf finish.
