How Lumiz works

The Sun as a Power Source – Light when it gets dark

Each Lumiz lantern is equipped with a compact solar panel. This panel collects sunlight during the day and automatically charges the built-in battery. Once it gets dark, the lantern uses this stored energy to power the LED light.

Special features of Lumiz

  • Completely wireless – no power outlet needed
  • Automatically turns on and off thanks to built-in light sensor
  • Equipped with thermal protection for heat and frost
  • Rechargeable battery is replaceable
  • Weather-resistant and maintenance-free

The Sun as a Power Source – Light When It Gets Dark

Each Lumiz lantern is equipped with a compact solar panel. This panel collects sunlight during the day and automatically charges the battery. Once it gets dark, the lantern uses this stored energy to power the LED light.

How it works

  • During the day: The solar panel captures sunlight and converts it into electricity

  • Storage: The power is stored in the built-in rechargeable battery

  • At dusk: The integrated light sensor detects darkness and automatically switches the light on

  • When it gets light again: The light turns off and charging resumes

Why burn time may vary

The burn time of a Lumiz lantern can vary. It depends on how much sunlight the lantern absorbs during the day and on the outdoor temperature. This variation is completely normal and typical of all battery-powered products.

Safety First: Automatic shut-off in heat or frost

The batteries in our solar modules come with thermal protection. This means they automatically shut down in extreme temperatures to prevent damage or overheating.

In hot weather:

If the battery temperature rises above approx. 60 °C (140 °F), it will automatically shut off. It may already perform slightly less efficiently from around 40 °C (104 °F). But don’t worry – on such sunny days, the lanterns usually charge extra well.

In cold weather:

If the temperature drops below freezing (around –15 °C / 5 °F), the battery also shuts off to avoid damage. As soon as the temperature rises again, the lantern resumes normal function.

This smart safety system keeps your Lumiz lantern operating safely and reliably – all year round.

About the Battery in Your Lumiz Lantern

Each Lumiz lantern contains a rechargeable AAA NiMH battery (1.2 volts). This battery plays a vital role by storing the solar energy collected during the day. At dusk, it powers the LED light automatically.

We deliberately use NiMH (Nickel-Metal Hydride) batteries, as they are more eco-friendly than older NiCd types and do not suffer from the “memory effect”. This means you can recharge them even if they’re not fully drained.

Key Features:

  • Size: AAA (standard)
  • Type: NiMH, rechargeable, 1.2 V, approx. 700 mAh
  • Replaceable: Easy to change yourself to extend the lantern’s life
  • Low maintenance: No special care needed – just recharge via sunlight
  • Durable: Suitable for daily outdoor use in all seasons

Replacing the Battery

Always use a rechargeable AAA NiMH battery (1.2 V, approx. 700 mAh) when replacing it. Only then will your Lumiz continue to function properly and provide long-lasting, atmospheric outdoor lighting.

Rechargeable batteries have a limited lifespan – we recommend replacing them after 12 to 15 months of regular use.

If you store your Lumiz indoors during the winter, be sure to remove the battery to prolong the lifespan of both the lantern and the battery.

Why Is the placement of solar lighting important?

The performance of Lumiz solar lighting depends entirely on sunlight. If the solar panel doesn’t receive enough sunlight, the battery won’t charge properly, which means the lantern may not shine as long—or may not light up at all.
Proper placement is essential for optimal use and maximum burn time.

Placement Tips

  • Sunlight: Choose a spot that gets at least 4–6 hours of direct sunlight per day

  • Avoid shade: Keep the lantern away from trees, walls, or roof edges that cast shadows

  • Keep the panel clean: Dust and dirt can reduce charging efficiency

  • Freestanding or hanging: Position or hang the lantern so that the solar panel faces upward and remains unobstructed
