Second,we can see,there are four led lights in the head of it.behind it there have a switch.
Now we can take about it:
Solar flashlights are essential for any emergency kit, for both home and car. They can be used at a moment's notice and do not require anything but the power of the sun to recharge. Most of these flashlights use LED bulbs, which use far less power but provide an amazing degree of illumination. Because they are less draining on a battery, they are ideal for use with solar power.
Solar flashlights are perfect for camping and hiking. Because they are designed to be charged via the sun, there is no need to carry an extra supply of batteries. Most of these flashlights have solar panels integrated into the design of the flashlight itself, and so simply leaving them sitting in the sun during the day is usually enough to charge them for a full night's worth of use. They are also compact enough to easily fit into a backpack with the rest of your needed equipment.
Solar flashlights are commonly used as replacements for kerosene-burning lanterns. Aside from the fire dangers inherent in using an open flame for lighting purposes, kerosene also costs money. Using a more eco-friendly solar powered light can save a user a substantial amount of money over the long run. They are also much more convenient than a gas lantern because they are easier to pack.
