Types of Flashlights

If you want to see in the dark, think of flashlights. Everyone should have one or two hand lanterns, either by power outages, camping trips or travel in the basement. Of course, there are all kinds of flashlights available which can make the choice of one a little difficult.

Flashlights

Main types of flashlights

Incandescent light bulbs

These lanterns have existed for a longer time and are often the least expensive. The light produced is usually bright, but this type of luz spends energy producing heat. Batteries and light bulbs do not last long in these lanterns.

LED lights

The light emitting diodes are a type of semiconductor. LED lights have a long life because they lose very little energy. LED lights do not have filaments of glass making them very durable. Both batteries and light bulbs LED lamps have a lifespan much longer than incandescent bulb flashlights, but this may require a higher initial cost. Originally available only in the colored lights, LED flashlights are available in a “white” light (which is actually more a blue light). Many people find that this light is very natural, while others are more accustomed to the yellow light of the electric light. For more information follow this wholesale website.

HID, or high intensity discharge lamps

High intensity discharge lamps have an electrical current that passes through a ball prepared of ionized gas. HID headlights are not as common as the others and are voluminous and often expensive, but produce very bright light that passes through the darkness like a knife, with a long lasting light bulb.

Xenon lamps, halogen and krypton

Some bulbs incandescent are filled with a pressurized gas, which helps to prolong the life of the filament on the inside, so that the bulb is brighter without drain the batteries faster. Currently, these are the brightest headlights available, although they are not as tough or long-lasting as LED headlights.

Lanterns that are shaken

To shake the magnets inside the flashlight for a minute it gets several hours of LED light. The light is not very bright, but the lack of batteries means that these lanterns will be always ready, which makes them perfect for an emergency situation. Be careful with headlights of agitation as powerful magnets can damage computers, credit card and pacemaker strips.

Lanterns for head

The convenience of having your hands free using a flashlight for the head is a popular alternative, especially for hikers and cyclists. Like hand lanterns, they are available with different types of light bulbs. Many are adjustable for different levels of brightness and different angles, making them perfect for all types of activities requiring hands-free.
