I have an 870 with a surefire light on it and I love it but I might be getting an ar off of my buddy so if I do I want a light for that as well. I have two questions.
1.) how bright should a tactical light be? what is the lumen cut off for a good tactical flashlight? 2.) I want to buy a light that could be used seperately from the gun so I don't want a light that will be too hard to take off the gun. My main question is, does anyone know of a tactical light that uses batteries that are more commonly found than cr123's? i would like to get one that ran on tripple or double a's but I'm open to suggestions. Lemme know what you guys think. When I turn 21 and get my pistol permit....if the wonderful state of new york (cough cough) will give me one, I would like the light I buy to be a light that I could quickly take off my rifle to use with my pistol if I need to search my house. |

1. A common misconception is that lumens are a measure of "brightness". Rather than measuring brightness (or, luminous intensity, which is measured by the candela), the lumen is a measure of luminous flux, the total amount of light captured by the eye.
Therefore saying, "X-lumens is too bright" is a categorical error. X-lumens concentrated in a small area may be bright while the same X-lumens distributed over a large area will be relatively dim. Wikipedia has a good explanation here. Look for a Light that controls its output with the proper throw and spill for your intended application. 2. Most Tactical Lights use 123A batteries due to their high energy density and excellent performance in various environments. Be prepared to sacrifice appreciable performance if you insist on AA or AAA batteries. While the idea of having one light for both your pistol and your long gun sounds desirable, the compact size of handguns and the need for high output lights on long guns makes these two applications highly specialized and distinct. You will likely be best served in finding dedicated Lights for each weapon. Hope this is helpful. |

John, if you get an LED light that runs on two 123 primary cells, you can also run it on rechargeable rcr123's, also know as 16340's. You can get about ten of them and a good charger and then it's free after that.
Good explanation by Elzetta. A lot of lumens emmited through a wide angle optic or reflector will not have a super intense hotspot. |
