Massachusetts Institute of Technology (MIT) conducted an evaluation of solar lanterns through its CITE program, and the Sun King Pro, created by Greenlight Planet, hit the number-one spot on its final ranking list.

Greenlight Planet is maker of performance-oriented and sustainable solar-powered lanterns now available in two sizes – the new Sun King Pro being their lead product on the market.

Blending industry-leading innovation with design, these portable devices feature convenience and versatility, with the philanthropic perk that with all U.S. sales, profits of the product help provide clean, economical lighting solutions to underserved communities worldwide.

In the MIT evaluation, the Sun King Pro came out on top as the overall highest-rated solar lantern ranked for superior charge time, run time on high setting, brightness, task and ambient lighting, luminous range and resistance to moisture.

The CITE team investigated three dimensions of each product: Suitability, Scalability and Sustainability. “MIT created the first impartial evaluation of products intended for poverty alleviation, recognizing that rural people in emerging markets should not be viewed as charity cases,” said Patrick Walsh, co-founder, Greenlight Planet.

The Sun King Solo was top rated among mid-priced products, $20 to $40, and the Sun King Eco was top rated among entry-level products, less than $20.

MIT recently hosted the Scaling Development Ventures conference, bringing together experts from the international development and business communities to examine the best way to bring poverty-alleviating solutions to market at scale. Greenlight Planet’s Global Partnership Advisor Laurens Friso spoke at the conference.
