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 Performance (HP) and High Lumen (HL). 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
- Law enforcement duty light
- Day-to-day industrial use
- Maintaining vehicles
- General contracting work
- Stinger® LED
- Strion® LED
- TLR-1®/TLR-1s® (weapon-mount light)
- TLR-2®/TLR-2s® (weapon-mount light)
- High Performance (HP): A good choice for down-range applications requiring optimal beam distance, as these flashlights throw light a long distance.
Performance Characteristics Typical Uses Examples of Available Products - High-candela beam
- Delivers long-range lighting
- Sheds a bright peripheral beam
- 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 and down-range illumination
- Stinger® LED HP
- Stinger DS® LED HP
- Strion® LED HP
- TLR-1 HP™ (weapon-mounted light)
- TLR-1s HP™ (weapon-mounted 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™
- Stinger® LED HL™
- Stinger DS® LED HL™
- Strion® LED HL™
- TLR-1® HL™ (weapon-mount light)
- TLR-2® HL™ (weapon-mount light)
