Shopping for flashlights If that's the case, you'll want to educate yourself on a few things before you settle on one for yourself. Flashlights are available in a wide range of materials which you should acquaint yourself with. In addition to materials, you'll also want to know about a few terms that will make purchasing the right flashlight a breeze. Take a look at the article below to learn about flashlight casing materials and terms.

Facts about Flashlights:

  1. Aluminum: Aluminum flashlights are rugged and long-lasting. They can be a bit more expensive and heavy, but the weight can be comforting when you are checking out a bump in the night. You can also find mini flashlights with aluminum casings, and these are perfect for stashing in a purse or glove box.

  2. Plastic: Inexpensive and lightweight, plastic flashlights are perfect for light use. If you only need a flashlight when you change a fuse in the basement or look for a dropped earring behind a dresser, plastic flashlights are sufficient.

  3. Beam patterns: The beam pattern will affect the way you can use flashlights and headlamps, so you'll want choose the right one for the job or keep a variety available. Spots flashlights give a narrow, long, fixed amount of light. They're good for finding a route. Flood flashlights give a wide, fixed amount of light. They're great for slow night hiking or stationary tasks such as working on a car or bicycle. Adjustable flashlights let you switch between spots and floods, so they're ideal for times when you may need both types of light, such as when camping. Strobe flashlights give a pulsing beam of light, which makes them excellent for search and rescue. Strobes are more common on headlamps than flashlights.

  4. Half-life brightness: Half-life brightness is a measure of a flashlight's brightness when the batteries are 50 percent drained. Only some flashlights will have this technical specification noted.

  5. Lumens: Lumens is a measurement of the intensity of light. There are many different ways to measure lumens, so most flashlights and headlamps will not give this specification.

  6. Lux: Lux is a measurement of the amount of light that falls on a surface, often measured at two meters because that's about where light falls when holding a flashlight straight in front of you. As a standard, the full moon is considered to be 0.25 lux.

  7. Waterproof: This indicates that a flashlight can be submersed in shallow water for a short period of time.

  8. Water-resistant: This indicates that rain or water splashes will not damage a flashlight.
