Lighting &quot;prolongs the day&quot; and allows activity during the night (eg studying) and can be supplied by various energy sources. Traditionally, a fire pit provides basic lighting, but the quality of lighting is poor, and the source poses health (fume inhalation) and fire hazards, especially if used indoors. Candles provide a portable light source, but are considered expensive and the quality of lighting is also poor. Oil lamps are relatively common, being a better quality and more versatile source of lighting than candles, with adjustable intensity; however, they also carry risks of smoke inhalation and fire. Hand torches are common, and batteries are easy to find at local stores; however batteries are expensive and undesirable from the point of view of environmental conservation. Electric light, powered by an accumulator, provides better quality lighting. The accumulator can be recharged during the day with a photovoltaic solar panel or any other source of electricity. This Strategy will promote the development of actions aimed at increasing access to electric lighting, which is versatile, safe and of good quality.
