Great Shine with LED Flashlights
I had my first LED flashlight nearly nine years ago. It was a small keychain powered by a button-cell battery. Since then, LED flashlights have evolved and current models have more luminous lights using more LEDs.
Light-emitting diodes or LEDs are solid-state transistors which give off light when a current passes through them. But unlike incandescent bulbs, it has no filaments, and no bulbs. It doesn’t burn, nor produce much heat. And best of all, it consumes a small amount of power.
The small wattage makes the bright LED flashlight a very green proposition. It doesn’t have to use a large energy source to create light and it doesn’t generate lots of heat either. And since it’s a single piece, it has a long life span.
Although normal LEDs come in all colors, the transistors used in flashlights tend to have a bluish tinge. This is not really a impediment to having a luminous flashlight. In fact, on sale now small projectors which use LEDs for the lighting element.
The titanium LED torch can be found in different sizes. There are the thumb-sized models which are smaller than a finger, with larger units using banks of LEDs. Using multiple LEDs, the size of a lighting unit can be as large as any normal flashlight, with a variety of designs. There was even a flashlight which make use a circular field of LEDs for a flashlight torch making the reflector unit, with a rectangular set on the side but without the reflector unit. This would be good when camping, replacing portable battery powered fluorescent bulbs.
