Question: How many lumans is this light?
Document: Good price and have many features. It gives a good light, good quality. Looks attractive. Light weight and easy to use.
taze mode works for a few seconds then no more light, light is weak. would not order again. to big cheap junk holder for belt, Taiwan junk
It seems to be a good product. I wish the flash light was a little stronger. I really don't know how to test it, because I don't want to use it on my family or friends!
Have raccoons in the area as well has lose dogs. This makes me feel safer in the event that one of these animals wants to get to close. The arc is load and the light is bright.
Also the flash light screen plastic has scratches on it but i did buy mine used. It comes with a charging cable that is really short and a belt holder with loop and a lanyard (that little string thing you can grab) attached.Overall it's a good flashlight that you can recharge and it also has a stun gun.
If we had children in the house, I would exercise extreme caution, since this is NOT a toy. I treat both units with respect, as serious weapons of defense. The on/off switch is at the base of the unit. The buttons to activate the light and the stun gun are on opposite sides of the unit, and are very distinct, protecting the user against accidental discharge.
I'm just a regular guy not a police officer or nothing i was buying a pc game and wanted the free shipping so i bought this. I actually never bought a flashlight or stun gun before.4 stars because it works, the flash light and stun. The light is bright. When i pressed the stun button i got scared.
This stun gun is great and the look of it looks like it would hurt but not lethal. The only problem is that after a while of using the flashlight, it started to strobe the light and doesn't give you a solid light. I didn't drop it or impact it in any way. One day I was using the light and turned it off and then back on and then all the sudden, I see strobing. Not the greatest but that's not what I bought it for anyway
works as stated. I got this for my wife so she can feel safe when going to class late at night
