Sonnenglas, a product from South Africa that looks like a lamp straight out of a fairy tale, is a full-fledged source of light for people living in places without adequate power supply.
Sonnenglas is handmade. This ensures the highest quality as well as durability.
The jar that Sonnenglas is based on, is a preserve jar made out of 100% recyclable glass. So, usage or discardation of Sonnenglas won’t lead to environmental hazards.
Since the materials used to build it can be procured from local markets, the cost of production is significantly lower than other solar lamps.
The production of Sonnenglas has created jobs for over 50 previously unemployed men and women from the townships Alexandra and Soweto in Johannesburg.
Sonnenglas is equipped with a USB port. In case of no sunshine, you can charge it with any micro-USB mobile phone charger.
The battery of Sonnenglas can hold its charge over months. After one month of shelf life, the battery suffers a loss of only 30% of its charge.
The battery within the jar is designed to last for at least 800 load cycles. Under normal usage conditions, its life expectancy is around 5 years.
A Sonnenglas jar has 19 lumens, which is equivalent to the brightness of 4 candles. It may be visibly brighter since the light shines onto the bottom made of glass and is reflected outward.
The LEDs in Sonnenglas have a color temperature of 4000 Kelvin. This is between the light of a bulb (3000 K) and sun light (5600 K). It has a higher color temperature than an electric bulb (3000 K) but less than sun light (5600 K). It can be altered by filling the jar with desired decoration.
Sonnenglas is waterproof. You can conveniently leave it outside as long as the lid is firmly shut to prevent humidity from entering the jar.
Under direct sunlight during summer, 6-9 hours of charging time is enough to get it fully charged. During spring and fall, it may take around 10-12 hours to charge. In winter it can take several days. It varies greatly as per your geographical location and climatic conditions. On an average, 1 hour of charge will give you 1 hour of light.
Though Sonnenglas was built with the intention of being used in power-scarce areas, it can be used in various other ways. Some of them are:
Besides that, it comes with a special feature! Sonnenglas can be customized as per your taste with sand, pebbles, fried flowers and fruits.
