I use this for a duty flashlight. I am a police officer working night shift. I have used this light for three months now. I can not tell you how awesome this light is. The bright light has a great flood excellent for use in field searches. I like the med. setting for traffic stops and the low for writing information off of reflective surfaces that glare. The strobe has been used to help back up officers find me. I have dropped this light several times and it has battle scars but always works. This is a tool that could save your life. The battery life is great.
