Energy Requirements of the Screening Sites in a COVID-19 Hub and Spoke Testing Approach

As the spread of COVID-19 increases globally, the need for more readily available testing sites with reliable energy supplies has become necessary, especially in regions where a significant portion of the population lives with limited or no access to the electrical grid. Prepared in collaboration with the Schatz Energy Research Center and the Energy Sector Management … Read More

Lithium-ion Batteries Part II: Safety

Lithium-ion batteries are cost-effective, high capacity, and capable of long cycle life when properly used in off-grid products. They can, however, present a serious safety hazard if poorly manufactured or improperly charged and discharged. Good design practices can mitigate the danger from these batteries and should always be used for off-grid products. This Technical Note … Read More

Procurement of Stand-alone Solar Kits for Humanitarian Aid

This Technical Note provides guidance on procuring pico-solar and solar home system (SHS) kits for humanitarian aid. It presents the relevance of the Lighting Global Quality Standards, key procurement considerations, and a step-by-step procurement guide.

Quality Matters

In 2017, Lighting Global tested 17 top-selling, non-quality verified solar products from retail stores in Ethiopia, Kenya, Myanmar, Nigeria, and Tanzania. All 17 products failed to meet Lighting Global Quality Assurance (QA) standards for pico-PV products, which test for energy efficiency, product durability, and other factors important to off-grid consumer experience. Results indicate that non-quality … Read More

Human Health: LED Lighting, Insects, and Wavelength

This article examines the issue of insects attracted to lights in the nighttime environment and the risk to people from insects carrying diseases. A review of the current understanding is given, along with possible ways to reduce attraction, in the context of LEDs used in off-grid lighting products.
