B) Possible Battery Failure
Sometimes the battery of the device is damaged due to reasons such as falling and hitting or other cases. It should also be noted that the life of batteries is limited and after a certain number of times they are charged, they lose their efficiency and it is time to replace them.
C) Bruising!
If your flashlight doesn’t work, maybe the LEDs or other parts are damaged and you need to repair them. If it’s out of order, consider buying a new flashlight.
D) Contact With Water
Perhaps unintentionally, your gadget has been exposed to water. Despite all its advantages, the flashlight does not tolerate water at all; unless its designers have equipped these tools with waterproof features from the beginning.
E) Heat the Flashlight
If your flashlight gets too hot, it is likely to prevent the battery and its diodes from working properly and may even damage them. To solve this problem, leave it alone for a short time. By turning it off, let it rest for a few minutes and then resume its work.
9. How Does a Flashlight Work?
The basis of the work of the flashlight is based on the electrical energy that flows between two metal strips, and its source is the batteries that are embedded in it. These batteries are connected to a metal plate or sheet, which, by being placed between two positive and negative electrodes, causes the flow of electricity. This flow easily acts as a factor for turning on the lamp and producing light and illumination.
When the device is turned off, the relevant key is in the off state, which means that the power flow is not established and causes the lamp to turn off and cut off the lighting. In this case, two metal strips are separated from each other and the electricity flow is cut off.

These devices are divided into two groups: “chargeable police light” and “battery-powered police light”.
This device is often made of metal or strong plastic and is known for its low weight and high strength and resistance. Its power and range of illumination are high and sometimes it illuminates a distance of several hundred meters. The mentioned gadgets have the possibility of high zoom and their body material is waterproof and resistant to corrosion and rust. The lamps of this type of flashlight are selected from high-quality LEDs with a lot of light.
Another feature of the police flashlight is its holders, which are used to attach to the wrist, clothes or backpack.
Its leather, plastic or cotton strap is placed at the end of the body and behind the battery. The built-in keys on the device, apart from turning it off and on, are useful for activating the side lights and setting the exposure modes.
The new models of these devices are charged in two ways with the help of Micro USB or Type-C ports.
11. What is the Highest Lumen for a Flashlight?
The amount of brightness and light that a lamp or flashlight produces per second is determined by the measurement unit lumen. This amount is different in lamps, light sources and types of flashlights, and its amount should be considered as an important criterion in choosing these devices.
Different flashlight models may have different modes and levels of brightness; For example, 200, 400, 800, 1600, 3200, 6400, 12800 and 25000 lumens, these numbers are present in some current market models. By selecting and pressing the corresponding key on the device or by touching it every time, you can achieve higher lumens of brightness.
You should determine the desired brightness based on your needs; For example, the brightness of 1 to 10 lumens may be enough to light up a book page for reading in special conditions, 10 to 30 lumens will light up the surrounding area as much as the light of a candle, 100 lumens seems to be enough for normal use or lighting up the road surface. ;
But if you are looking for a lost object, person or animal in a dark space, a flashlight with 300 lumens will light up to a distance of 50 meters, leave the use of 1000 lumens and above for security forces, rescue groups and policemen!
