There are many important factors to consider when buying a torch. LED Torches Australia have put together a simplified guide on how to purchase the right torch for your particular needs. Perhaps the most crucial component is the purpose of your portable flashlight. The purpose will largely affect the other factors. For example, the lumens (or total light output) you need, will depend on precisely what you are using the torch for. Other key elements to consider when purchasing a torch include your preferred run time, battery and beam types, plus the impact resistance and water resistance. Make sure you’ve thought about all of these factors when purchasing your torch, so you can get the absolute most out of your LED product.
Light emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a television screen or illuminate a traffic light.Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit . But unlike ordinary incandescent bulbs, they don’t have a filament that will burn out, and they don’t get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor.
Low power requirement:
Most types can be operated with battery power supplies.
Most of the power supplied to an LED is converted into radiation in the desired form, with minimal heat production.
