Solar flashlights are extremely versatile solar products, and as such, there is a lot of variation among them. Solar flashlights can be just as bright or as dim as any other flashlight. In general, flashlights that have the option to be powered by a crank are less bright, ranging from as little as 50-100 lumens.

- The crank turns gears that create a speed mechanical advantage and turn the generator at a fast rate.
- The rotors of the generator convert motion into electrical energy that then charges a battery.
- The current then goes to the LEDs to create visible light. The flashlight has a crank on its backside that you can turn to generate the electricity required to charge the battery and light the bulbs, which are light-emitting diode (LED) bulbs.
- LED bulbs require much less electricity than standard bulbs, and they put out more light.

Dynamo Torch/Squeeze Flashlight
Dynamo or sometimes called a Squeeze Flashlight is an Emergency Flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator supplying electric current to an incandescent bulb or light-emitting diode.
This flashlight must be pumped continuously during use, with the flywheel turning the generator between squeezes to keep the light going continuously. Because electrical power is produced only when the handle is squeezed, switches are not needed.
