About DeciWatt...

Deciwatt is a product development initiative with a mission to explore how to do more with less; in turn empowering people through sustainable and affordable low power solutions.

This approach led Martin and Jim to create GravityLight.
Faced with the charity SolarAid’s challenge to create an LED lantern under $10 to replace damaging & ubiquitous kerosene lamps, Martin & Jim quickly realized the need to look beyond solar and battery power.

They took a different approach to benchmarking the amount of power and light needed asking “is it better than a kerosene lamp”. Along with the ever-increasing efficiency of LED lights, this led them to explore what much lower levels of power could deliver.

GravityLight only generates a deciwatt or two of power but has a superior light to the majority of kerosene lamps used by those without electricity, as well as being significantly more sustainable, safe and healthy. With no running costs, at $10, a GravityLight would pay for itself within a few months, freeing people from fuel poverty and the increasing costs of kerosene.

As LEDs continue to rapidly increase their lumens per watt and – as Koomey’s Law predicts – the energy efficiency of devices doubles every two years – this has huge implications for low cost, off grid lighting as well as computing and communication equipment. This is the driving force behind Deciwatt’s mission to explore how to do more with less.
