The MagCharger has an aluminium reflector and a glass lens.
As for the steeping down, isn't this a prgrammed feature of the modern Mag LEDs rather than due to heat? So they offer level max output for 3 mins or so, then gradually step down to a lower constant output. The gradual step down is done as most people probably wouldn't notice. And if you don't notice, what's the harm in stepping down to reduce heat and promote run time?
If you turn it off and on it'll reset the light back to max again for 3 mins before stepping down. No idea if this is how the MagTac works, but that's how I thought the XL200 and ML125 where setup.
I suppose another way of looking at it, is it always turns on in a "turbo" mode, which will gradually reduce to the normal 'high' mode. In this respect there are many other 'premium' lights that do the same, be it 4Sevens, Klarus, JetBeam, EagleTac and so on.
The only LED Maglites that I currently own are the 2D (with the Rebel driver. It was given to me as a gift), and the XL200. I read, in some posts here on CPF, that people who own these (D-cell) LED lights are still complaining that the output is greatly sacrified, even after just ten minutes or so of use, because of the steep drain on the D alkaline batteries - not a new issue, by any means. I couldn't honestly say that I've experienced that, because I hate running down D batteries and having to constantly replace them. That, and the fact that I don't have a practical use for a D cell light, as an EDC light, because of its enormous size vs. desirable output and runtimes. Can't exactly EDC a D cell light comfortably on a belt, without attracting a lot of attention to yourself, not to mention, the discomfort of having such a huge light always attached to one's person. To me, is just doesn't make sense, when there are smaller, higher output, also very well-constructed lights available. Now - if that light put out 900 lumens, then I'd say "who cares....gotta have the output, so I'll sacrifice size for output", and deal with the strange stares, and extra weight. But that's not the case, and my other lights produce better, brighter output, while using more economical, and eco-friendly 18650s, mainly. I love not having to buy batteries all the time (like I was doing, when I used nothing but D-cell lights), knowing that I'm going to get hundreds of charges on one or two batteries, with consistent, regulated output, rather going through hundreds or primaries (and dollars). On the other hand, there simply are some lights that don't offer up the rechargeable-friendly battery option, but DO have other amazing features, so they become "gotta have it" lights, regardless. I just don't use them nearly as much as the 18650 lights, mostly for economical reasons.
I had all but forgotten about the MAGCharger. Thanks for making mention of that. There was a time when I wanted to own one, because of the higher output (which Maglite used to rate in candlepower, rather than lumens, as they do today), and the recharging feature (in spite of the now obsolete NiCd battery it used to come with - horrible battery, with memory problems.
NiCads are just inherently inconsistent in maintaining battery capacity, when charged at different times (i.e., without first fully draining, or "cycling" them - EVERY time). I'm glad they finally upgraded to a NiMH battery that can be retrofitted to all of their previous MAGCharger models.
I hadn't even heard of any of these other companies (I doubt they even existed - the likes of EagleTac, Fenix, etc.), or I may have started exerimenting with their lights, years ago. At the time, the most powerful light I owned was the 6D incandescent Mag, which I had upgraded with the Magnum star bulb, so the MAGCharger seemed like a dream come true, but it had its pitfalls, and the cost was one of them.
It makes sense that they use the aluminum reflector and glass lense on the MAGCharger; but notice that's the only model that seems to offer up that combination of materials (lens/reflector) from the start, while the rest of their models seem to have remained all plastic. I think the reasons they did, with this model, were to keep the lens and reflector from melting, due to the heat produced by the now considered old-school "improved", higher output halogen bulb. I don't care how "modern" the halogen bulb is, it's going to produce heat, and lots of it, very quickly. There's no way around that. Something (like the reflector...?) needs to act as a heatsink, to avoid having the light overheating, sacrificing output and run times.
Re-addressing the step-down feature of a Maglite, I (and I'm sure, many others) would rather they just regulate their lights better, and heatsink them better, so they don't have to be stepped down incrementally, just to stay cool, or give better runtimes. This MAGTac is a great step in the right direction, with the far higher output than anything ever offered up before, in a far more EDC-friendly package. I just hope that the output is real, and not constantly stepping down in output, just to live up to the runtime claim.
I also read somewhere that a glass lens is a better medium, for producing the purest beam of light, as opposed to plastic. And once the plastic lens become scratched, there is a sacrifice in the beam quality. (can someone verify this, please?)
Wouldn't it be cool of Corningware (the makers of Gorilla Glass, the very thin, strong, and highly scratch-resistant glass used on the displays of many of today's smart devices) teamed up with Mag and used their glass on the lenses of all Mag products? That's some pretty strong, and thin glass. It's not indestructible, but it's pretty tough, and heavily scratch resistant. I can vouch for the glass, because it's been on my iPhone 4, which I purchased a year ago (with no screen protector film ever used), and there isn't a mark on it. I only wish all smart devices used that glass, rather than cheap, easy-to-scratch plastic).
For you Californians who like Tommy's chili, this would be like getting Ruby's Diner (or pick your favorite burger joint) to join up with Tommy's Burgers, using Tommy's chili in their burgers - a little jolt of chili flavor. They would KILL the competition!!! But - that's another thread...probably in another forum altogether lol...and you either love Tommy's chili, or you hate it. It's one of those deals.
I own the XL200, but hadn't noticed a stepping down of output, while in use for several minutes; but I'm using Eneloops, and maybe that affects the step-down feature...? I also own EagleTac's D25LC2, and have never noticed the step-down feature kicking in (from Turbo), even after several minutes of use. It does get pretty hot, though, in the hand, so I often resort to switching lights (maybe to an M20-X, for instance) if I'm going to be using a light for an extended period. I'm using a EagleTac 3100 MaH Lithium Ion batteriy in the D25...
It's kind of hard to understand the draw of the MAGCharger, these days. It's huge, weighs a ton (comparitively speaking), only puts out 240 lumens, and for only two hours, at that. Most tactical lights weigh about a fourth as much, are several inches shorter, and produce upwards of an hour-and-a-half of light at full power (many of them, at 500 plus floody lumens); at a mere 300+ lumen ("lower") output, they far exceed the runtime of the MAGCharger); not all, but many, in a far less expensive package than Maglite are offering - well, with the exception of this new MAGTac -somewhat.
Are Mag still charging 100 plus dollars for the MAGCharger system? I would love to see them update the MAGCharger to produce a higher lumen output - or at least a longer run time, at the currently-rated 240 lumens, and do away, once and for all, with the halogen lamp altogether. I know opinions vary, but that's mine. The LEDs of today are far more stable and stronger than their halogen counterparts - far less prone to fail, under hard use, and, as a general rule, the better LEDs (not the ones you find in those 1-dollar, 9-LED grocery counter lights) have a far longer rated service life than halogens.
I'm not slamming Maglite at all. I have several of their lights, and I don't plan on getting rid of any more than I have (Over the years, I've given many of them as gifts, to parents, friends, etc., because I really believed in their product, and I wanted everyone I knew and cared about to have at least one Maglite); but for me to want to use the ones I've got left, I need to upgrade the rest of the ones I haven't already upgraded, with decent LED drivers, so they can keep up with today's lights - especially if I have to continue using primary batteries, rather than rechargeables.
As for LEO baton use of the Maglite...how about just letting the light be a light (a smaller, more powerful one, like this new MAGTac), and if you must have a baton - just carry a baton...? I"m not an LEO, and I'm probably oversimplifying a long-standing argument for carrying a big, super-heavy light, in spite of the fact that (as a stock product) it does not outshine the newer lights, weighing in at far less, and much easier to belt carry - especially if you're carrying more than one light at a time, which many flashaholics do, anyway.
My 6D light could stand a serious upgrade, because it won't really keep up with my little tiny Pelican M6 incandescent, as far as brightness (The M6 is rated at 74 lumens...I don't know if that's OTF, or not). The run time on the M6 is terrible, though (I think maybe an hour or so, and of course, it is quickly and progressivly dimming from the very start, as all non-regulated lights do); and of course, the beam is not focusable.
Anyway - I'm still very intrigued by Maglite's new offering, here; and even if just to keep up with the tradition of owning at least some Mags, I'd like to own one (especially if it really has a 4-hour runtime at the full rated output - that would be pretty impressive, in and of itself, for a Maglite product); but I'm probably going to hold off until the price drops at least a little bit, on this new model; and I won't be surprised when they offer a higher power model, with more features. In the meantime, I'm drooling over EagleTac's new G25C2 MKII. Yes, it's thirty dollars more than the MagTac, but it's significantly more light output/lighter package/super robust construction, waterproof to IPX-8 standards, and I can run it on a single 18650 battery (or 2 CR123s), with options to use more CR123s or 18650s (with the appropriate battery extenders), for far better run times. That's hard to beat, for the money, and I really like having the extra battery/battery type options available to me.
Gotta get both lol. Need to start saving my pennies, here...
