Frequently Asked Questions


The KULUMI MINI’s LED has a life expectancy of 50,000 hours. MINI has 4 levels of brightness. At full power, the lamp emits 150 lumens of light up to 10 meters (33 feet) or as few as 10 lumens when just a little light is needed. Depending on the brightness setting used, Mini can last for 4-35h.                                         













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.

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:

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.

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.

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***

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***
