Maybe you are a security officer placed in a small community where you always hear the sound of steps from some suspected people. You have been trying to apprehend them to no avail you think they may be powerful than you, so you later discovered blinding their vision temporarily is the only best option for you which you have also tried. Still, your weak flashlight is failing you several times. So you are thinking of how many lumens can help you do the work? Worry not, as this writeup has made known to you, the number of lumens needed to blind a vision temporarily is eight lumens in the darkness while twenty lumens in daylight. Note, no matter the intensity, visible light can never be used to blind a vision permanently but can only block it in the meantime.


Lumens is the real measure of illumination from a source or the quantity of light or bright derived from a specific source. Lumens in your flashlights determine the quantity of brightness to be produced. That is to say, the more the lumens, the more the brightness.

Determining the specific measure of lumen for your flashlights depends on what you want to use the flashlight for, which drives you towards buying a flashlight.

Let say, for instance, you are buying your flashlight just to be using it as an alternative vision for electric powers like checking things within 100 meters. A flashlight with 10 to 20 lumens is okay for you. If you are to be using it for home and some outdoor vision within 120 meters, then you need 20 to 150 lumens to be available in your flashlight. If it is a hiking, camping, and security purpose, 120 to 200 lumens is recommended. In contrast, 200 to 500 lumens is recommended for sailing, fishing, and tactic security purpose.


Shining a flashlight under the sky may be legal and, at the time, maybe illegal. It is legal and maybe allowed when your lumen is below 1000, while it is illegal because it is detrimental to society. Although the negative effect may be known in the present time but believe me, it will worsen than you expected.
