Types of Flashlights
The LED Flashlight works with light-emitting diodes. Generally they are more power efficient, and provide longer battery life. The classic Incandescent Flashlight works with gas filled lightbulbs and a reflector. When battery life begins to fade so does the intensity of the light. The High Intensity Discharge Flashlight is a more complicated version, it operates through the use of ionized gas and electricity. Generally HID Flashlights tends to be brighter than the traditional variety and tend to cover a wider field.History
