Wow I did not know there was so much to learn about flashlights. Are you all crazy??? I love it!! Ok so I would like something I could carry in a holster. Want distance and very bright but a little bit of flood also. I drive a wrecker so at nights I need a good light to check out the cars and the area I am in. Might be on for 5 minutes and then nothing for a few days. Entering a dark lot at night to get cars or find papers. So a light that could have several levels. Ready to spend $75-$100.00 I guess the rechargeable batteries or lithiums might be good. Also need a rugged light. Read up on so many. Is the Olight m21 a good choice? Any suggestions and please forgive me for any ignorance I have dispalyed. The wife already said I am spending too much time reading about flashlights but I have a long way to go. Thanks
