Pro tip: when buying a LED flashlight, you should consider the use of the flashlight. You need a flashlight that will withstand the toughest conditions even if it falls. Don’t forget about the light output from the flashlight.

Reliability and durability

If you decide to buy the best flashlight, why not get a flashlight worth your money? You don’t need a flashlight that breaks or stops working after a few days. What makes a reliable flashlight? It doesn’t come with electrical issues, and it goes on or off when you need it to.

 For a high level of reliability, the flashlight should have a body that withstands a few drops on soft and hard surfaces. Whether you like it or not, the flashlight will drop, just make sure that it can withstand the fall.

Pro tip: a reliable and a durable flashlight will not lose its brightness just because it fell. A reliable Redline flashlight has an aircraft-grade construction which makes it strong and resistant to breaks.

This is an important feature in most tactical flashlights. The bezel holds the lens of the flashlight to the body protecting the lens and the LED bulb from any damage.

Pro tip: the best Redline flashlights have a convex lens which increases the functionality of the flashlight. You can also use the lens to illuminate an area in different colors because different colors alter or enhance visibility.

The Bulbs

The best Redline flashlights have LED bulbs. The LED bulb can give about 50,000hours of continuous use. So, you will have one bulb for about five years.

Pro Tip: LED bulbs are preferable because they don’t have a filament. This makes them more shock resistant and more reliable. Also, LED lighting offers the best vision regardless of the existing environmental conditions.

Flashlight performance

You also need to consider the general performance of the flashlight. All flashlights are measured and rated using the ANSI FL1 standards put forth in 2009. The Redline flashlights meet the requirements of these standards.

To measure performance, you have to consider the light output, beam distance, the runtime, water resistance, and the impact resistance.

Pro tip: you cannot determine the fill performance and functionality of a Redline flashlight by considering one feature. You have to place all these elements under consideration. The battery type also affects the flashlight’s performance. Redline flashlights have disposable AAA or AA batteries.

Light Modes

Other than the high, low and medium light brightness, your Redline flashlight will also have additional special modes like SOS and Strobe. These are important features of tactical flashlights.

Pro tip: the best Redline flashlights have strobe and SOS modes. Strobe is an important feature for tactical cases as it confuses the targets. It creates a Bucha effect, and this is why you need this in a tactical training flashlight. SOS, also called Morse code is an important signaling feature. If you need a Redline flashlight for emergency purposes, make sure that it comes with an SOS feature.

Other features and factors include light filters, tail switch, reflectors, the price, as well as the size and the weight of the flashlight.
