Solar flash lights are great innovations that we really can use at this age of global warming. The sun harnesses such a big amount of energy can actually be tapped to produce power into a flashlight. This type of flashlight is much smaller than usual. It has the panels for getting energy from the sun and other the other end, a bulb that emits light even without the use electricity.
Hot It Works
Solar flash lights utilize the energy of the sun and then convert it into electrical energy via PV or photovoltaic cell. This panel is just on the outer side of the flashlight. These types of portable lights use LED / light emitting diode. LED is used because they need less electrical current to light up a bulb and they generally last longer. On average, it can lasts up to 100,000 hours, which is much practical to use compared to an incandescent light that can only last 1000 hours.
Batteries that are used in these special flashlights are solar charged batteries. It uses nickel and lithium. Cadmium batteries can work in flashlights and do not need any replacements even if regularly used in 2 years. A regular battery can last up to 15 hours while a solar charged battery can last up to 2500 hours and is rechargeable.
