Flashlight Guide

It doesn’t matter if you’re a mechanic, a plumber, an electrician or none of the above; flashlights are a piece of equipment that is essential in nearly every toolbox. With so many models on the market, how do you know which kind to choose? Learn everything you need to know about with our flashlight guide.


What is a Flashlight?

Flashlights are devices that provide illumination without the use of electricity. This strong beam of light can be easily controlled for specific tasks. These tools are necessary for countless environments and situations. Like most tools, flashlights are not a one size fits all for users. They come in three different categories or grades: industrial, general purpose and tactical. Learn all about these uses to find the right device to accomplish the task at hand.

Industrial Flashlights

Warehouses and facilities require an industrial flashlight for safe and efficient use. These flashlights range in lumen and brightness depending on the model. However, the most important characteristic for facility use is in the safety rating. These characteristics are determined based on what hazardous materials may be present. With the wrong flashlight, it could cause an explosive or chemical reaction. Safety standards fall into four different categories: classes, divisions groups and temperature codes.

Class Type of Hazardous Material Class Location Examples
Class I Flammable gases, vapors or liquids. Petroleum refineries, utility gas plants, gasoline storage and dispensing areas and dry cleaning plants
Class II Combustible dusts Grain elevators, coal preparation plants, and producers of plastics, medicines and fireworks, spices, sugar and cocoa
Class III Ignitable fibers and flyings Textile mills and plants that create sawdust as a byproduct
Division Presence of Hazardous Material Division Location Examples
Division I Where ignitable concentrations of flammable gases, vapors or liquids can exist all of the time or some of the time under normal operating conditions Loading zones or areas near relief valves at a petroleum refinery because flammable hazardous materials exist under normal operations
Division II Where ignitable concentrations of flammable gases, vapors, or liquids are not likely to exist under normal operating conditions Storage room with oil drums where an ignitable concentration of gas vapors would only exist under abnormal operating conditions, like if a drum were to be leaking
Group Nature of Hazardous Material
Group A Acetylene (typically used in welding)
Group B Hydrogen or gases of equivalent hazard (including ethylene oxide, propylene oxide, etc.)
Group C Ethylene or gases of equivalent hazard (including carbon monoxide, ether, etc.)
Group D Propane (including butane, gasoline, natural gas, ammonia, hexane, ethanol, etc.)
Group E Metal dust (division 1 only – including aluminum and magnesium dust)
Group F Coal dust (including charcoal dust, coal, etc.)
Group G Grain dust (including starch, flour, etc.)
Temperature Code Max Surface Temperature (°F) Max Surface Temperature (°C)
T1 842 450
T2 572 300
T2A 536 280
T2B 500 260
T2D 419 215
T3 392 200
T3A 356 180
T3B 329 165
T3C 320 160
T4 275 135
T4A 248 120
T5 212 100
T6 185 85

Tactical Flashlights

Tactical flashlights provide bright vision no matter the time of day or place. This form of illumination goes above and beyond to provide more than just light. These types of flashlights are typically used in professional defense industries including:

  • Search and rescue
  • Military use
  • Security/police/law enforcement
  • Firemen
  • Outdoorsmen/hunter/hiker
  • Self defense

With their compact and lightweight design, tactical flashlights allow for simultaneous use of another tool, such as a weapon. In fact, some models are designed to be mounted to a weapon for low-light shooting. It can also withstand the shock and vibration of a firearm, which makes it the No. 1 choice for law enforcement professions.

Tactical Flashlights

This type of instruments provides more light than a general model without the heavy weight, making it easily transportable. Because of the simple design and versatility, tactical flashlights are also commonly used among civilians for self-defense.

General Purpose Flashlights

The basic kind of flashlight has a simple, yet effective design. These handheld devices are lightweight for easy transport and relatively inexpensive. Their typical uses are for everyday tasks like household chores, car repairs, hiking and exploration, etc. When it comes to choosing a general purpose flashlight, there are three categories to consider: light output, battery type and size. Learn all about them:

  • Brightness: The light output of general flashlights is what mostly dictates price difference. Lumen capability and beam distance are the two main considerations and typically go hand-in-hand. Light output can range from 20 lumens to 3500 lumens.
  • Battery type: Flashlights can come with disposable, rechargeable and renewable batteries. Disposable is the most common type, as you can pick up batteries nearly anywhere. However, renewable flashlights are recommended for emergency kits because of the potential for scarce resources, even batteries.
  • Size and Weight: The overall size of your flashlight comes down to personal preference and can be decided based on application. However, with the proper accessories like holsters and cases, any flashlight can be easily transported.

There is a wide selection of quality flashlights to choose from. It all comes to down to how, when and where you will be using the tool.
