I'm working long-term as a security guard in the Puget Sound area and I need some advice on a well-balanced, practical, and long-lasting flashlight or flashlights that will help me do my job better and keep my surroundings illuminated. I've seen another post that correlates a little but I'm not looking to hardwire any electrical components in my vehicle, nore is operating or charging temperature a huge concern. I will soon be using an old patrol car and need something that will do the job right. Right now I'm using a Maglite but it just isn't quite cutting it. I'm planning on staying at my company for a while and want to invest in a great flashlight that will last me for years and help me fulfill my duties. Any input/advice/experience is greatly appreciated!
