Practical Tinka LED solar lantern: for mobile use without a mains connection The solar lantern's rechargeable battery can keep the LEDs lit for between four and 150 hours - depending on how dimmable it is - and provides cosy light. Tinka's body and carrying handle are made of extruded, maintenance-free aluminium with a powder coating, while the panes are made of frosted acrylic, which makes the light emitted particularly soft. There are countless areas of application for the Tinka LED solar lantern: balcony, terrace, garden or when camping by the lake. It is also an energy-efficient lighting solution for the tables in a beer garden.
