7 simple practical tips for buying a tactical flashlight
A flashlight is one of the most important every day carry (EDC) item that we should have with us. Not only does this amazing device light your path but can as well be used as a defense weapon, saving you from a dangerous situation.
Since the buyer likely intends to use the tactical flashlight in a hazardous situation, it’s important to consider the material, weight, light output method, lumens, strobe settings, and power source when buying a tactical flashlight.
1: Material of body must be anodized aluminum
There are usually three types of material used to make flashlight’s body including plastic, aluminum, and anodized aluminum. Anodized aluminum adds a layer of aluminum oxide on the outer surface, toughening it against scrapes and scratches. Anodized aluminum flashlight is much more reliably.
Conclusion: tactical flashlight’s material must be anodized aluminum alloy by DANKUNG standards
2: XM-L2 Emitter rather than Q5 or T6 emitter
CREE emitter is the core part of a flashlight. CREE, Incorporated was founded in 1987 at North Carolina State University, has become a dominant force in flashlight world.
The most common used CREE emitters are XM-L2, XM-L T6, and XP- Q5
XM-L2 has the overwhelming better performance in terms of brightness, reliability, throw, flood.
Take the 'lumen' for example. Lumens means the measure of the total amount of light from a given source. It’s an important of metric of brightness. Another metric of brightness is Candela which is less used.
Theoretically XM-L2 has maximum 1052 lumens, XM-T6 has maximum 850 lumens and Q5 has maximum 248 lumens.
Conclusion: Choose flashlights with XM-L2 Emitter rather than Q5 or T6 emitter, even though XM-L2 is is sort of expensive.
Caution: Some vendors falsely indicate the lumens. Please see below image which shows the small 1-emitter flashlight has 1800 lumens, that's impossible.
3: Zoomable for adjustable throw and flood
Throw and flood are two most used terms when describing a flashlight. Generally speaking, throw means distance of beam and flood means scope of beam.
A flashlight the has a lot of flood will illuminate a very large area but not very far. Torches that have a long throw have a very focused beam and you can light up something much long away.
The primary element determining flood and throw is the emitter, XM-L2 has the the best flood and throw. The second factor is the innner construction of flashlight head.
A good tactical flashlight has function of zoomming to adjust the flood and throw.
XM-L2’s maximum throw is 874 yards (800 meters), XM-T6’s maximum throw is 546 yards (500 meters), XM-Q5 is maxium throw is 382 yards (350 meters).
Conclusion: Choose the zoomable flashlight with XM-L2 emitter.
4: Low-Power-Weak-Beam Switch
‘low-power-weak-beam’ means the flashlight automatically switches to weak beam when the battery is almost running out. ‘low-power-cut-off’ is the flashlight automatically power off when the battery is almost running out for protecting the electric circuit and battery.
This flashlight is designed as Low-Power-Weak-Beam Switch may save the man’s life in the unexpected hazardous situations.
