Product Description

Color: Black | Size: 4-D Cell


Bright lights, burly cases, fail-safe on/off switches, virtual indestructibility: there are very good reasons to rave about Mag Instrument flashlights. It goes without saying that a flashlight defeats its own purpose if it can't be trusted, which is why so many people spend a little extra for this four D-cell Mag-Lite. We've dropped ours off ladders, kicked it down stairs--just generally abused the thing--and it lights up now just as readily as it did when we first turned it on. Speaking of which, the on/off switch is one of the first things to fail on generic flashlights. Mag-Lite's switch is rubber coated and weather protected; frankly, it seems incapable of ever wearing out, even after thousands of clicks. Plus, twisting the flashlight's head gives you an option between a tight beam and a floodlight. More importantly, the combination of a supertough krypton gas lamp and high-quality reflectors provides unusually bright light. There's also an extra lamp in the tail cap so you've always got a backup--how many other flashlights deliver that?

But the Mag's indestructibility is its main selling point. Mag Instrument builds its flashlights with ultrastrong aluminum alloy cases that have been anodized both inside and out to resist rust. High-quality O-rings at both openings keep water away from the batteries. It's hard to imagine damaging one of these lights. Think of it this way: if, as one of our customers suggests, there were a kingdom of flashlights, Mag-Lite would be crowned king. --Jon Groebner

I've owned one of these for almost 10 years now. It is the best flashlight I ever purchased. I bought it when I was in college and worked as a Student Auxiliary for the college Police Department. My flashlight has suffered a great deal more then most flashlights can handle. It's been dropped, run over, used as a hammer, used to pound in tent stakes, constantly taken on road trips, I can't even remember all of the things I've done to it. All I can tell you is it still works.
To keep it working well you should occasionally apply a small amount of Vaseline to the threads to keep the threads and O-rings lubricated. If you do this it should last you a long time.

Maybe you're a cop or security guard, maybe you're a guy who lives in a place where you can't carry a firearm, maybe you're just someone looking to fill the 'use of force' void that exists between shooting someone the bird and shooting them between the eyes. Any way you look at it, lets not beat around the bush here... Anyone buying this light is doing so for one reason only, the 'light' aspect being totally secondary to that one reason. It's a club that doubles as a flashlight.

So, how do we judge it on the objective criteria?

As a whuppin' stick, it definitely works- so well that some 'kinder, gentler' Police Departments don't even allow it anymore. Kind of a bummer that they discontinued the thinner 6C; barring finding one second hand and paying a real scalpers price for it, the 5D/6D is the pretty much the only 'in production' option in the Mag line for a "big defensive flashlight" but that's OK. Unless you have very small hands, the 6D is perfectly controllable.

It's big. Really, really big. The light itself is about 19.5" long- a foot and a half- in total. When weighted down with cels, it's heavy, too.

You will want to tread lightly with this, as it definitely would generate enough striking force to fracture a skull, break bones. Be damn sure you're legally justified to use it, if you ever do use it. You can hurt someone with it. It's does cut a pretty intimidating profile. Walking around with one, it's almost as if you're carrying a bat. In some situations, this is OK. In other situations, where drawing attention to yourself isn't the desired outcome, you'd definitely want to leave this one home (in this regard, probably worth noting that given its weight, this is essentially a two handed club.

I have three of these flashlights and they are fantastic. I keep one in the garage (see accessory section for mounting bracket), one on the fireplace mantle, and one in my car. They all work perfectly, project a bright, adjustable beam, and feel great in your hand. Not only does it work in normal conditions, but the gaskets and buttons do a great job keeping water out - I live in the Pacific Northwest and use it in the rain frequently with no problems.
This is the same model that many of our local law enforcement types use day-in / day-out. I'd image that may a miscreant has received a "bop" on the head with one of these babies and will think twice before resuming their layabout ways.
Get one of these with three fresh Duracell's and you're set. This flashlight will last you a lifetime!

Once in a while you'll encounter a product that's so far out front that the others should pick up their marbles and go home. Mag-Lites are the standard bearer in the flashlight category. (Were it not for the picture, you would hardly know from the product description up there that we're talking about a 4-cell flashlight.)
The primary job of a flashlight is, not surprisingly, to create light. Mag gets more light out of their flashlights than anybody. Maybe it's the bulb, or the reflector. But NO flashlight will come close to putting out as much light as a Mag.
Another quality we hope to find in any product is functionality -- does it work every time, or mainly when you don't need it? I can't recall more than a time or two that a Mag failed to come on. I've dropped them from heights that would have destroyed anything less and they still worked.
I have an old black AA-size Mini-Mag here that spent about a decade in the cockpits of airplanes -- the poorest lighted places this side of the Black Forest -- so it got a world of use. The place on the end cap for attaching a lanyard or hanging ring is worn completely through. But the little guy still works like a charm.
The switch on this D-cell model is under live rubber; it has a solid click on and off. The beam is adjustible to a sharp spot. You'll probably want to set it there and leave it alone.
I am certain that batteries last longer in a Mag-lite. The only explanation for this would seem to be that a tiny bit of battery drain occurs on some others. Before I became 100% converted to Mags I would too often pick up a flashlight that was full of dead batteries. I can go for years without changing the batteries in a Mag-lite.
All Mags are rugged.

Few flashlights will grab more attention than a 6D Cell Maglite. It's 20" long and weighs well over 3 lbs with batteries. As alluded in other reviews, this really guns for the guy instincts. It's exaggerated and gives the same feeling as seeing the volume go to 11 (á la Spinal Tap). Ever since I first saw one on display 20 years ago, I've wanted it (but had to settle for a Mini-Mag). Of course, as a Maglite, it lives up to their reputation of being virtually indestructable and a good substitute for a baseball bat.
However, in light of recent innovations in LED technology, it doesn't have as much practical value. As one would expect with a 6D (9 volt) light, it is one that can signal satellites. When I first saw it, it was brighter than anything else, at least operating from standard batteries. 20 years later, it still uses the same technology, albeit with the availability of the Xenon "Mag-num" bulb, which adds 23% brightness (per Maglite's web site). Other technologies have emerged that make this beast show its age, especially the so-called "tactical" lights, some of which are smaller than a Mini-mag, but brighter than the 6D. Don't get me wrong. It's tough as nails and extraordinarily bright. But, the 3D Cell Maglite with the LED upgrade puts out a comparable amount of light, while consuming only half the batteries and being 40% smaller. As of this writing (7/2007), there is no LED upgrade bulb available from Maglite, save the 4D Cell version, used with 2 dummy D-Cells (why?)
Third-party vendors have some good ones, but they are either dimmer or don't focus. One even costs $75+ (for a $25 chassis). One company boasts its upgrade bulb will yield 140 lumens; for comparison, the Mag claims the 6D Cell with the Xenon bulb yields 218 lumens.
