A flashlight, also known as a torch, is a portable, battery operated device designed to provide light. It features three main parts: the material from which it is made, the battery, and the light source – which can be either a LED (light emitting diode) or an incandescent light bulb. When it comes to being able to see in the dark, a flashlight is the best tool to have in hand. Whether for camping trips, power outages, hunting, diving and biking in the dark, or simply for using it around the house, a flashlight will help you see things clearly. Since different tasks require different types of light, different types of flashlights have been designed over the years to meet the demands of different users.
Utility Flashlights
Commonly seen in household’s toolboxes, this type can either have a LED or an incandescent light bulb. Although flashlights with incandescent light bulbs are less expensive, a great part of their light energy is wasted as heat, so their battery usually has a short lifespan. LED flashlights, on the other hand, have a higher initial cost but last much longer as they don’t produce heat. Plus, LED lights are available in different colours such as blue, red and white light (which people tend to find more natural than the yellow colour of incandescent lights).
