Cool Shine with LED Flashlights
I bought my first LED flashlight about nine years ago. It was a handy keychain powered by a button-cell battery. Since that time, LED flashlights have advanced a lot and today’s models have shinier lights and more LEDs.
Light-emitting diodes or LEDs are solid-state transistors which shine when a current passes through them. But unlike incandescent flashlights, it has no filaments, and no bulbs. It doesn’t burn, nor produce much heat. And best of all, it uses a minuscule amount of energy.
The small power usage makes the best LED flashlight a very novel proposition. It doesn’t require a large battery to produce light and it doesn’t produce lots of heat either. And since it’s a single diode, it has a long life span.
Although regular LEDs come in a wide range colors, the transistors used in flashlights usually have a bluish tinge. This is not really a impediment to having a shiny flashlight. In fact, on sale now small projectors which have LEDs for the lighting element.
The titanium LED torch are available in an array of sizes. There are the thumb-sized models which are smaller than a finger, with larger units using arrays of LEDs. Using arrays LEDs, the size of a lamps can be as large as any common flashlight, with any number of designs. There was even one design which has a circular group of LEDs for a flashlight lamp complete with reflector unit, which included a rectangular set on the side but without the reflector unit. This is great when outdoors, replacing portable battery powered fluorescent lamps.
