Cost savings

d.light lanterns can completely eliminate the need for kerosene lanterns in households. The cost savings for customers can be significant, as families may spend 10 to 25 percent of their monthly income on kerosene oil. For a typical farmer or shopkeeper, d.light products will pay for themselves in as few as two months, meaning customers will save money every week for years to come.

Income generation

The bright and reliable light from our products supports income-generating activities such as farming and retail. A United Nations Development Program study demonstrates that household businesses with improved lighting have up to a 30 percent increase in income due to increased productivity at night. d.light customers have reported an increase in monthly income by as much as 50 percent from the extended workday.

Better study environment

The poor light quality and noxious fumes of
kerosene lanterns hinder the ability of children to study effectively. d.light lanterns are bright enough to facilitate longer and more effective studying hours, which directly lead to increased learning and higher test scores. d.light customers share how their children, who previously often studied less than one hour per night, are now able to study as much as four hours per evening with a d.light lantern. Moreover, a World Bank project study shows pass rates of an entire school increased from 57 percent to 100 percent after students studied with bright solar lighting.

Healthy and safe homes

Kerosene lamps are a key contributor to indoor air pollution, which is documented to have disastrous health effects, ranging from tuberculosis to cancer. Kerosene lanterns have also caused countless deaths by ingestion, burn injuries and related complications, and fatal fires. At a minimum, kerosene users experience diminished eyesight and visual health. d.light lanterns are extremely safe and use super-bright LEDs that do not emit any pollutants.

Reduction in carbon emissions

According to Lawrence Berkeley National Laboratory research, the annual greenhouse gas emissions from fuel-based lighting in developing countries is nearly 200 million tons. A single kerosene lamp emits nearly half a ton of CO₂ over a lifetime of 5 years (UNFCCC). Every d.light lantern purchased can completely replace one or more kerosene lamps, contributing to global carbon emissions reductions on the scale of hundreds of thousands of tons.
