I found this article while looking for information on beam
pattern comparisons. I couldn’t improve
on it, so I’m sharing it.
Streamlight Flashlight 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
Tradition Series: Meant for general, multi-purpose
use, these lights are designed for the broadest range of lighting applications
at the best value. Characteristics
include: Optimal balance of candela and lumens, longest regulated run times, the
best value. Uses include:
Day-to-day industrial use, law enforcement duty light, maintaining
vehicles, general contracting work.
FlashlightDistributor products include: PolyStinger® LED/DS® LED, Stinger®
LED/DS® LED, Strion® LED, TLR-1®/TLR-1s® (weapon-mounted light), TLR-2®/TLR-2s®
(weapon-mounted light). http://www.flashlightdistributor.com/Streamlight.aspx?Streamlight=75660
High Performance (HP): A good choice for down-range
applications requiring optimal beam distance, as these flashlights throw light
a long distance. Characteristics
include: High-candela beam, delivers
long-range lighting, sheds a bright peripheral beam. Uses include: 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. FlashlightDistributor products include: Stinger® LED HP/DS® LED HP, Strion® LED HP, TLR-1
HP™ (weapon-mounted light), TLR-1s HP™ (weapon-mounted light). http://www.flashlightdistributor.com/Streamlight.aspx?Streamlight=75860
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. Characteristics
include: High lumen beam, delivers
maximum illumination, provides a good level of candela. Uses include:
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.
Flashlight products include: ProTac® HL™, Stinger® LED HL™/DS® LED HL™, Strion®
LED HL™, TLR-1® HL™ (weapon-mounted light), TLR-2® HL™ (weapon-mounted light). http://www.flashlightdistributor.com/Streamlight.aspx?Streamlight=75453
