Flashlight Applications and Beam Patterns

Having the right flashlight that meets your lighting needs is important. That's one of the reasons Streamlight developed three series of lights: Tradition, High Lumen (HL) and High Performance, High Lumen (HPL). Each series offers a different balance of features and can be used for a variety of applications.

We understand it can sometimes be difficult to determine which lights work best for a variety of applications. When choosing a flashlight, keep the following in mind:

  • Tradition Series: Meant for general, multi-purpose use, these lights are designed for the broadest range of lighting applications at the best value.
    Performance Characteristics Typical Uses Examples of Available Products
    • Optimal balance of candela and lumens
    • Longest regulated run times
    • The best value
    • Day-to-day industrial use
    • Law enforcement duty light
    • Maintaining vehicles
    • General contracting work
    • PolyStinger® LED/DS® LED
    • Stinger® LED/DS® LED
    • Strion® LED
    • TLR-1®/TLR-1®s (weapon-mount light)
    • TLR-2®/TLR-2®s (weapon-mount light)
  • High Lumen (HL): Gives you maximum illumination, providing full situational awareness by delivering extraordinary brightness in a wide beam pattern. These lights are ideal for smaller areas where you need a lot of light, but not an exceptionally long reach.
    Performance Characteristics Typical Uses Examples of Available Products
    • High lumen beam
    • Delivers maximum illumination
    • Provides a good level of candela
    • Clearing a dark scene or searching an alley
    • Lighting a campsite
    • Vehicle stops or searches
    • Wherever you want wide scene illumination, while
      still being small enough to fit in your pocket
    • ProTac HL®/ProTac HL® 3
    • Scorpion® HL
    • Stinger LED HL®/DS LED HL®
    • Strion LED HL®
    • TLR-1 HL® (weapon-mount light)
    • TLR-2 HL® (weapon-mount light)
  • High Performance, High Lumen (HPL): A good choice for down-range applications requiring optimal beam distance, as these flashlights throw light a long distance and feature an enhanced lumen output.
    Performance Characteristics Typical Uses Examples of Available Products
    • High-candela beam
    • Delivers long-range lighting
    • Sheds a bright peripheral beam
    • More light on your target at a distance
    • See all the way to the end of a dark alley or down
      a wooded path
    • Inspecting utility lines from the ground
    • Search and rescue missions
    • Down-range illumination
    • Stinger® HPL™/DS® HPL™
    • Strion® HPL™
    • TLR-1® HPL™ (weapon-mounted light)
