The Home 120 provides home lightning through an energy system composed of a solar panel, a Lithium Ferro-Phosphate (LFP) battery and lumen lamps. Distributed by Sun King, it can power the multiple lamps (up to 3) with three brightness levels (Turbo: 200 lumens; Normal: 100 lumens and Low: 40 lumens) and 360-degree ambient wide-angle spread for over 24 hours of lightning on a day’s charge. It has an integrated 5,5 V USB port and a 12 V power output designed to power any 12V DC appliances. This product features a LED charging indicator that displays on a scale of 1 to 5 to help optimize panel position, a LED for battery indicator and the battery automatically switches to low power when running low, enabling 5 hours of additional light. Pay-As-You-Go functionality available with the organization’s Easybuy program. Introduction video to the Home 120 solar product.

Vetted Performance Status
This Solar Home System composed of 12 Wp maximum power polycrystalline silicon panel and 3,3 V and 12000 mAh Lithium Ferro-Phosphate (LFP) battery connected to the 3 light points, has the following running hours after a typical day of solar charging (5 kWh/m2/day): the three lights with turbo brightness setting (200 lumens each) run for 5,4 hours per day of solar charging, resulting in a total light output of 590 lumens and 3000 lumen-hours/solar-day. Within the low setting (40 lumens each) the system runs for 21 hours/day, resulting in a total of 140 lumens and 2900 lumen-hours/solar-day. 94% of the original output remains after 2.000 hours run time. Normal brightness setting not tested. Complete vetted performance in the Lightning Global assessment here.
