Strong light torches are very strong, even if dropped on the ground will not easily damaged, so it is also used for outdoor lighting. But no matter how strong and durable things, use for a long time will inevitably appear some such and such small problems.

If there is a bright spot but the flashlight is not bright, then it shows that this is the problem of the flashlight switch, please check according to step 3; If it is not bright, please check whether the solder welding at the connection of the circuit bin and the circuit board is open welding or virtual welding. If there is open welding or virtual welding phenomenon, as long as the welding again can solve the problem that the strong light flashlight does not shine.
The second step to check the battery: we must first ensure that the battery has electricity and, and in accordance with the correct direction of the positive and negative battery into the battery, it should be noted that different models of batteries can not be used, of course, the old and new degree of different batteries can not be mixed.
The third step to check the switch of the tail cover: first gently unscrew the cover of the tail of the flashlight, after opening it, you can see that the outer ring of the switch spring has a switch pressure ring with two concave points. Check whether the switch ring is loose by turning it clockwise on the two concave points with tweezers or scissors. Make sure that the switch ring is firmly pressed on the switch and is not loose.
