About the Startup

Describe your product in 3 words.

Instant. Lighting. Always.

How did you come up with the idea for this product?

GravityLight was designed as a viable alternative to kerosene lighting for low-income, off-grid, households.

Globally, over 1 billion people live without access to electricity and rely instead on dangerous, expensive and polluting kerosene lamps for their home lighting - to study by, to work by, to cook by, all evening, every night. This number rises to over 2 billion people when you include families that have unreliable or intermittent electricity, who rely on kerosene when the power goes out, regularly, and for days on end.

Using kerosene for home lighting is really bad. The fumes are as harmful as those from smoking cigarettes, and children trying to study by it are heavily exposed from an early age. Unintentional ingestion of kerosene is the leading cause of child poisoning in the developing world. 30% of all burn cases admitted to hospitals in Nigeria were attributed to kerosene lamp explosions. A single kerosene lamp emits 150 kg of carbon dioxide per year and is a significant cause of black carbon. Added to this, it's a poverty trap - consuming up to 30% of earnings in low-income households; this for lighting alone.

We were moved to try and find a solution to this problem. This is how we came up with GravityLight.

What makes your product special?

GravityLight is unique. It contains no batteries, so can be stored for a long time without batteries spoiling or going flat. It works indoors, independent of the weather, time of day or season. It produces power for lighting on demand, with no pre-charge, for as many hours as needed, as long as the weight stays off the floor.

GravityLight is brought to you by Deciwatt Ltd. Every purchase of GravityLight funds The GravityLight Foundation in it's mission to eradicate kerosene lighting in the developing world.

What has been the best part of your startup experience?

The response, support and goodwill from crowdfunders has been overwhelming. The flow of kind messages that flooded in when we introduced GravityLight to the world was phenomenal. Now seeing GravityLight being installed in low-income, off-grid homes, and seeing GravityLight offer lighting and comfort to normally on-grid homes in times of distress or disaster, has made the whole enterprise incredibly fulfilling.
