Question: Please tell me the diameter of the body. I have a 1 inch mount that I want to use for the flashlight..Will it work?
Document: I now have 3 of these. I use them for everything, from mounting on my AR-15 to my pistol to working on the car. This thing is so bright, that I use the lower output setting most of the time. And the 2 batteries seem to last for ever. And a charger too. Why spend $80 or more for a light you can mount on your weapon, when you can get a great one for 1/4 of the price?
I have 6 of these I use them every where I keep 1 in my car 1 in my work bag and a few in the house and one on my belt can't beat the beam for the price
**UPDATE** 3/31/14:  Lights have been working fine but I did want to change my stars from 4 to 3 and also just add a reason why. Build quality. The outside of these lights seem to be built "well", but what I really have a problem with is the two screws that hold the clip to the body of the flashlight.
So maybe this is a knock off but as far as I can tell this is a great little flashlight. I got the setup with the charger and batteries included. I haven't run the batteries out or used the charger yet but as long as they work this is a winner. I will update if I have any problems in the future.
I bought 2, one for home use and the other to mount as a tactical light on an M4 or AK47. I have already dropped the light on a hard surface twice and it survived. Now as for mounting it on a rifle with a remote pressure switch there's a problem. The MECO Remote Pressure Switch for UltraFire C8 CREE Q5 / R5 / T6 LED Torch Flashlight DOES NOT!!! fit this LED light.
I am completely satisfied with product so far. I have had it for three days and I use it daily. I am a technician, and other then my leatherman, my flashlight is my &#34;go to&#34; tool. I haven't killed a battery yet, so I cannot tell how long one actually lasts, but since I am on day 3, and it's still going, that is good enough for me.
Good light. Brighter than most will want, but will blind anyone and tone down for extended use...About the cheapest light that I have ever bought that I was more than satisfied with.....and I am a flashlight collector.. Sweet deal and a great light, but you know the China shipping must come by slow boat or mules, so you might anticipate a wait, order early and they might have some in stock or don't sweat the wait...
I have purchased a total of 5 of these, and they work great. I don't know if they are actually 1000 LM but they are bright. The batteries last pretty long in standby. I have seen 1 month so far. Having the spare charged and ready is definitely a plus!
I have had this for about a year now. Very bright light which reaches quite a distance. If that is what you want this light is it. The batteries work great also. Five stars is what this product deserves. I live on acreage and  the dog appreciates my being able to illuminate what she thinks I should look at! It has a few functions but spend a couple minutes with it and you will get it. The off/on switch holds the brightness/function that it was last on.
I use my flashlight every night that I work and at home often. I also use this light on the front of a tactical shotgun when needed and this thing just plain puts out, bright light lots of modes ( strobe works great for blinding criminals they never see what its attached to until its too late )  and excellent battery life. I plain on buying this item again from the same company and so have several other coworkers.
Answer: yes
