I'm looking for a good self-defense flashlight, self-defense purely by strobe not as an object to hit someone. I'm on a limited budget, is there a particular flashlight which specialises in this area and doesn't have some of the other premiere features which I don't need. I don't need a big battery, all I want is a very powerful strobe that is very fast and intuitive to operate. If possible I would prefer it if it was over 2,000 lumen, because I want it to be as effective as possible. I'm also looking for a small size. I have a traditional 5inch black tube, Atactical A1 one of the early cheap but decent flashlights maxes out at about 800 lumens The strobe is very powerful at night but I want something that might be useful in the daytime. Thanks
