If it's the actual taser brand flashlight it's actually smaller than the flashlight version. Also the taser flashlight is only a stun gun and not the actual taser, which you would have to be in arms reach of an attacker. This unit you can disable your attacker at 15ft away with the supplied cartilages as well as using it as a stun gun. Not sure what model you have but if it's the flashlight one from taser it's only a stun gun which is only effective as long as you hold it on your attacker vs giving an attacker a 30 second lightning ride from up to 15ft away
