How to choose led flashlight

Although the headlights have been widely used, however flashlight is still a choice to be irreplaceable when you want to bring the most powerful handheld light, have the ability to control light and deft precision, equipment Resetting a light to the task and signaling. These advances in production technology efficiency flashlight products created small, lightweight, handy and lighter than before. It’s easy to pick out the best LED flashlight for you after referring this article.

Factors when you are selecting a flashlight include:

  • Light output measured in lumens, said the intensity of light from the flashlight on high brightness settings, install more lighting. This is a tool to know the beam intensity, distance and type all affect the efficiency of light in the case. Light output can range from a modest 20 lumens to a scorching 3500 lumens terrain.
  • As far beam light will shine before the brightness decreases, as measured by the meter, with different distances with the brightness settings installed
  • Run Time measured by the hour, rounded to the nearest quarter hour long work to reduce the light output to 10% of the assessment of the new battery. Light output may decrease over time or suddenly reduced after the process runs continuously in a graph.
  • Impact resistance measured in meters, was tested by dropping into the concrete while maintaining the light is still functional, there is resistance to a light being run over, beaten with a heavy object.
  • Waterproof ability was assessed using IPX system. This is extremely important if you frequently have to use it in water.
  • Battery Type is an important factor in choosing a flashlight. With disposable batteries, which are used most or AA AAA, CR123A is a popular choice, but relatively expensive with a higher output voltage than the smaller size and weight, making there a bright flashlight in a smaller package and lighter. For rechargeable batteries, it was built in lithium-ion battery can be recharged via a USB connection, AC or DC outlet or solar energy at a higher upfront costs and reduce waste. The last type is renewable energy with integrated battery by a panel crank or solar energy is ideal for emergency kits.
  • Mode is divided into three levels of low, medium, high to have the option to throw a powerful beam on demand. Brightness mode may be shorter runtime. Some models may offer special mode so that users can program the sequence mode
  • Controls are divided into mode on / off lighting and switches with buttons and sliders or rotary. Typically, a flashlight is also now equipped with safety lock feature, preventing light from being accidentally switched on when not in use
  • Most flashlights are made of plastic or aluminum alloy. First flashlight use stainless steel. Agency cylinder is the most common shape, angularity against rolling supply and reduce slip grip.

When choosing buy flashlight, try to use it in dark places, to check the light from the flashlight is the most accurate and objective assessments.
