My husband and I own one of these great Mag-Lite Adjustable Flashlights. This is one heavy duty flashlight. It runs on 3 D batteries and has a good weight to it when the batteries are in it (but not too heavy to handle).
We have one in royal blue, a nice-looking flashlight if I say so myself. It has an adjustable beam that can be focused from a narrow to a wide beam (spot to flood). This flashlight is just a smidgen over a foot in length. It has come in handy when the power goes out, and my brother-in-law has one that he uses in the garage when he's working under the hood of his car or underneath the car itself.
You never realize how handy a flashlight can be until you are in a situation where it is too dark to see, and your trusty flashlight comes to the rescue. The flashlight is made of aluminum construction and is very durable. It has what they call a knurled design on the handle to make it easier to grip. When you hold onto this flashlight, you feel like you have something substantial in your hand.
My husband and I have gotten a lot of use out of this flashlight and look forward to getting much more from it. I would definitely recommend a Mag-Lite Flashlight to anyone who is looking for a good, heavy duty, nicely constructed flashlight with an adjustable beam.
