     MINI’s light is a hybrid between a lamp and a flashlight. Its light is directional like that of a flashlight and creates a uniform light like that of a lamp. MINI takes an amount of light, focuses it then spread it out more uniformly at 120 degrees. This gives a higher and more efficient lux to power ratio.
What kind of battery is it?

The KULUMI MINI has a rechargeable 3.2V/1500 mAh LiFePo4 battery, 1000-2000 charge cycles, and 4-35hrs of use depending on the brightness setting. The LED light has 4 brightness settings: 10% , 25% , 50% and 100%. For each one of these, the battery life will differ. 

Below is a breakdown of the battery life using MINI at different brightness settings:

How to recharge KULUMI Sheep?

KULUMI Sheep has an internal lithium battery that is rechargeable via our supplied microUSB cable, or any other normal microUSB cable. Simply plug in the cable in the little open section next to the zipper. We designed that little space so the charging cable can connect to the battery pack easily without having to open the zipper. When charging, a red light will appear below the Sheep’s neck, then turn orange when it is almost full, and turn green when it is fully charged.

Typical charge time (from empty to full): 5 hours

Each time the buttons are pressed when navigating, the time for auto-shutdown is reset.

When it is turned on again, it will resume playing where it left off.

Can the integrated buttons break by pressing a lot?

They are designed to be very durable even when pressed numerous times. But if there is any defect, please contact us promptly here.

Can KULUMI Sheep be washed?

Yes. But first, you need to remove the speaker/battery pack as it should NOT get wet. Open the zipper and detach the pack from the wires by pulling gently. The integrated wires and buttons can be soaked as they are waterproof.

Why is the zipper not sewn in at the top?

We designed the zipper this way so the slider/pull tab is hidden and out of reach of children. We wanted to prevent children from playing with the pull tab and accessing the battery pack/speaker. Parents can access the pull tab by pulling the zipper out gently. ***It is NOT a defect***

What is that little space next to the zipper?

We designed this space so it is easy to plug in the charging cable without having to open the zipper. ***It is NOT a defect***
