![]() The d.Light S30 receives specific mention in three pieces of academic research. dissertation, Delft University of Technology. Vega Garita, V., 2019, Integrating a Photovoltaic Panel and a Battery Pack in One Module: From concept to prototype. Ph.D. Vega‐Garita, V., Ramirez‐Elizondo, L., Narayan, N., Bauer, P., 2019, Integrating a photovoltaic storage system in one device: A critical review. Prog Photovolt Res Appl, 27, pp. Narayan, N., Vega-Garita, V., Qin, Z., Popovic-Gerber, J., Bauer, P., Zeman, M, 2020, The Long Road to Universal Electrification: A Critical Look at Present Pathways and Challenges. Energies, 13, 508. This is assisted by its ability to be placed upside-down on its angled top to focus light upwards.įurther specifications are available here (from the manufacturer) and here (from Lighting Global). ![]() ![]() The product’s conical design redirects light in all directions. It also features a smart LED indicator for solar charge intensity, a glow-in-the-dark button and is manufactured from UV resistant plastic that also makes it weather resistant to sun and rain. The d.Light S30 features a multiple-setting metal handle that allows for carrying or hanging from a hook. The product has two brightness settings and from a full day’s charging on a clear, sunny day it can provide 12 hours of light in its standard or 3 hours of light in its high (60 lm) brightness setting. The 2 LEDs inside the light point emit white light and are listed for a 60,000-hour lifetime. It is charged by an integrated monocrystalline silicon solar panel (0.33 Wp), or can also be charged with grid power using a standard Nokia phone charger (not included when purchasing this product). The d.Light S30 is a solar LED lantern powered by a Lithium Iron Phosphate battery (450 mAh, 3.2 V).
