Kulumi Mini: Top 10 Attractive Features


4 levels of brightness

LED is hailed as the best choice for more efficient, environmental-friendly, and cost-effective lighting. It is already replacing many traditional bulbs as it is highly energy-efficient, gives more light, produces less heat, is mercury-free, and costs less in the long run. LED uses less electricity for the same light output, i.e., about 85% less electricity than conventional lighting and about 18% less electricity than compact fluorescent lamps (CFL).


LEDs have a general life expectancy of 50,000 hours, and Kulumi Mini’s LED is no different. The LED will decay 6% after 6000 hours.

Kulumi Mini has 4 levels of brightness. At full power, the unit 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 be used for 4-35h.

Mini’s light is a hybrid between a lamp and a flashlight. A lamp’s light is uniform, but the range is short. A flashlight’s light is very bright but only lights up a particular spot. If we take that same light beam and spread it out, it will become very dim.

Mini’s light is directional like that of a flashlight and creates a uniform light like that of a lamp. The objective is to light up an area so that the light can be shared. Mini takes an amount of light, focuses it then spreads it out more uniformly at 120 degrees. This gives a higher and more efficient lux to power ratio.

Although Mini does not have a very long range, it is more than enough to light up the area in and around the house. For people who live in areas without access to electricity, Kulumi Mini brings joy and convenience to many.



8GB memory and 3 levels of content navigation

The Mini comes with a micro SD card of 8 GB with programmable content. There are 6 anti-tampering options to choose from should you wish to protect the content of the SD card.  We also have a version of Kulumi Mini that comes with internal memory to further protect the audio content.

The buttons are sturdy and allow you to easily navigate the 3 levels of content. 

The 3 levels are:

  1. Main/Root folder (e.g. Old Testament/ New Testament)
  2. Subfolder (e.g., Book of Genesis)
  3. File (e.g. Chapter 1)

In remote regions, local tribes, and communities, the audio content is programmed in the local dialect, and for many, it is the first time having access to this technology.

Built-in 2W speaker

Kulumi Mini’s speaker is loud enough for about 20 people to hear the audio content. In an enclosed space like a meeting hall where the sound resonates well, the speaker amplifies enough for everyone to hear. In gatherings and study sessions, it is often used to play songs, stories and educational materials, and to listen to the local radio station.

76 MHz – 108 MHz

Kulumi Mini receives modulated FM signals with a frequency range of 76 to 108 MHz. The tunable FM band can cover all the frequency-modulated radio bands within the country. The 800 mm cable that is included can be used as an antenna and plugged into the 3.5 mm earphone jack for better reception.


Built-in 0.7W rechargeable solar panel

The vision behind Kulumi started with a group of engineers who wanted to create a solar-powered lamp. That’s because for a lamp to actually work, it needs a source of power. And nothing can rival our free source of energy: Sunlight.

Although listed as feature #5, the solar panel is one of the most important aspects of Kulumi Mini. Whether you are in an area without access to electricity or encounter a sudden power outage, you can rely on the solar-powered Mini to give you light when you need it.

Kulumi Mini will take 10-12 hours to recharge under direct sunlight. This will vary depending on the intensity of the sun.


3.2V/1500mAh LiFePO4 battery, 1000-2000 charge cycles, 4-35h of use

With a durable lithium polyester battery that recharges via the solar panel or a standard micro-USB cable, Kulumi Mini can be used for 4-35 hours, depending on the brightness settings.

Mini can be left unused for weeks and even months until there’s a sudden need, and it will still turn on without any problem, thus making it the perfect tool to store in your drawer, hiking backpack, safety kit, or glove box for emergencies.

Use the included 500 mm micro-USB cable with a standard USB 5V power adapter to recharge via a power outlet. The typical charge time is 2 hours.

For people who live in areas without access to electricity, they can make full use of the long-lasting battery, using the light at night and letting the unit recharge via solar panel during the day. This also saves a lot of money as there is no need to buy disposable batteries that are not only short-lived and expensive but also harmful to the environment.


5V DC, 500mAh output

Once the unit has sufficient power, it can be used to charge other devices like mobile phones. This function comes in handy when your phone is running low and you need a source of power to keep it charged. Although it is not as powerful as the power banks on the market, it is still a very welcomed and useful feature.


195 g; 136 x 82 x 33mm

Kulumi Mini is a light-weight and compact lamp with a comfortable grip. The handle makes it easy to hold and to hang on a hook or a tree branch. It can also fit well in your pocket and in your backpack.

Weight: 195 g (0.429 lbs.)

Dimensions: 136 x 82 x 33mm (5.35” x 3.21” x 1.29”)


Weather/ Water/ Shock Resistant

Kulumi Mini is made of Plastic Polymer ABS, a weather-resistant material, so it can be used in various conditions such as sunshine, rain, wind, and even snow. It is not waterproof but water-resistant with a rating of IPX6, meaning it can resist high-pressure and heavy sprays of water.

The printed circuit board (PCB) also has a conformal coating applied to it. It is a thin polymeric film that protects electronic circuits from environments that may contain high humidity, airborne contaminants, and varying temperatures.

Kulumi Mini can withstand the hot tropical climates of Africa and the cold, snowy weather of Russia.

I gripped tightly the door handle as my Indonesian friend’s Toyota bounced us across a severely pot-holed road in the mountains on the island of Sulawesi in Indonesia. We had passed numerous ominous longsor (landslides).
