Know-How About The Tactical Flashlight For The Beginners

Nowadays, the demands of going a picnic, hiking or hunting become increasingly. In the condition of being overnight at the tough terrain like mountain, the purchase of the best tactical flashlight is considerable essential. Before buying this item, you need to know the specification as well as the feature or functionality of the product. All criteria will be synthesized and analyzed in this article.

To evaluate the efficiency of the flashlight, you can refer some parameters and the measurement as well.


There are several points worth noting about this parameter. For example, in the photometric data, the parameter is measured only after 3 minutes when the lights turn on, this is the measure of the OTF (Out the front) lumen measured by the prisms device. This measure will reduce the parameters of almost all kinds of flashlights, such as Fenix TK12 R5 with the old measurement is 280 lumens, but with the new measurement is only 245 lumens. Or Fenix LD 20 R5 newly launched has the parameter of 180 lumens, which is lower than Fenix LD 20 R4 205 lumens.

Run Time

The time used for the measurement is when the flashlights have 10% luminous intensity; in the old measure is 50%. In fact, the time from 50% to 10% for a high-end flashlight is usually much faster than the time from 100% to 50%. Therefore, this difference is not significant in the highest mode, only about 5 to 15 minutes depending on the light pattern or the type of battery.

Peak Beam Intensity

A new parameter is the peak beam intensity cd (Candela), measured at the beams of flashlights, usually located at the midpoint. You should take a careful look at this parameter, with the same flashlight of 200 lumens, which one having the higher peak beam intensity cd, means that this flashlight will be brighter.

Beam Distance

The beam distance is a parameter depending on Candela. Some firms will calculate based on cd quantities as 4sevens but some brands like Energizer will take actual measurements. It can be understood as the beam distance to the object will be equivalent to the time of the biggest light moon at 0.25 lux despite the fact that no one can see any objects at this distance.

Water Resistant

The specification of water resistance has only 3 standards: IPX: IPX4 – Water resistant to splashing to the flashlight such as rain, IPX7 – Immersion under 1 meter of water for at least 30 minutes, the highest standards IPX8, which requires the flashlight to perform well when being soaked at least 4 hours under 1 meter of water pressure, the manufacturer can only record details the depth of water, for example, IPX8 – 10 meters, it means that soak under 10 meters of water within 4 hours.

Impact Resistant

This parameter requires enduring a distance record with drop test, the drop test conditions are to drop at least 6 times to make sure the flashlight still functions properly.

Above are some criteria to determine the efficiency of the flashlight. Apart from these factors, you also need to consider the categories of the battery as below.

The Battery Type

The Battery type and availability for replacement are often the key factors when choosing a flashlight.

Disposable Battery: The battery size, which is used most commonly, are AAA or AA, always available. Besides, CR123A is also a popular choice, but it is more expensive and harder to find. They have a higher capacity with the smaller size and weight; which help you bring a brighter flashlight with the smaller and lighter luggage. The flashlight using batteries D is still available if you want one-size instruments to secure like a baton, or a flashlight, which is not mixed in the bag.

Rechargeable Battery: The lithium-ion battery attached can be recharged via the USB connection from a computer, AC or DC port or solar cells. The high battery price will be compensated by using with low-cost, no need to the battery available and minimize waste.

Renewable Battery: The flashlight with integrated battery, powered by hand crank or board need solar energy will be ideal for the rescue or survival tools.
