Philips Africa Innovation Hub.
Philips Lifelight Home is a solar-powered system that features two lumens with 3 brightness settings and an in-built USB port for universal charging of mobile phones and other electronic devices.
Philips LifeLight Home is a solar-powered lighting system that comprises two pendant luminaires with 3 LED brightness settings (35, 75, 150 lm) and an in-built USB port for charging phones and other electronic devices. Powered by a 4 W external solar panel and with a Lithium-ion battery (4400 mAh, 3.7 V), it gives up to 20 hours of light when fully charged. Pay-As-You-Go functionality and Bluetooth communication can be added.
This product was developed by the Philips Africa Innovation Hub with its headquarter in Nairobi, Kenya. It is a center for developing innovations ‘in Africa-for Africa’ in the areas of healthcare, lighting and healthy living.
Philips in partnership with banks, telco companies and microfinance institutions to create financing opportunities for customers.
Goal 7: Affordable and clean energy
Products are engineered in the Philips Africa Innovation Hub in Nairobi, Kenya, on mass customization.

Design specifications include the 4 W Polycrystalline silicon solar panel, a Lithium-ion battery (4400 mAh, 3.7 V) with an integrated USD port, and the two solar lights with 150 lumens each and 3 light settings: 35, 75, 150 Lm.
The product has a 2-year warranty covering manufacturing defects, however, according to Lightning Global, the battery is easily replaceable with common tools.
The Solar Home system battery lifecycle is unknown, however, lumens maintain over 98% of original output after 2,000 hours of run time.
In 2017, Philips was working in a new Solar Home plus system with three light points and extendable to five, with up to four USB outlets and two 12VDC outlets for powering electronic devices, such as fans or TVs. There is no further information about the progress on these performance targets.
When connected to the 3,8 Wp polycrystalline silicon module, the battery box powers the 150 Illuminance lamp for 4,8 hours and the 75 Illuminance lamp for 11 hours. Per day of solar charging, it is 3,5 hours for the 150 lm lamp and 7,6 hours for the 75 lm lamp, resulting in a total light output of 320 and 160 lumens, respectively. Total lightning service for this product is 1100 lumen-hours/solar-day for high brightness setting (150 lm lamp) and 1200 lumen-hours/solar-day for medium brightness setting (75 lm lamp).

This Solar Home System is a plug and play device, however, electrical installation and control guidelines provided by Philips must be followed to avoid electrical shocks.
Philips also commercializes two additional solar-powered lanterns models: Philips LifeLight and Philips LifeLight Plus.
There is no academic research on this specific product, however the following paper gives a review on solar home systems for rural electrification:
