Maglite XL100
Rating: 88%

Maglite are probably the best known maker of flashlights in the world.  They have a good deal of respect even among us enthusiasts for making well put together, durable lights.  However until quite recently they did have one real drawback.  Their mainstay models really were starting to look rather obsolete in the opening years of the 21st century, for one very simple reason: They have been very, very slow to embrace LED technology.

The smaller models in particular suffered heavily where the shock resistance and higher efficiencies were most obvious and gave LED lights a truly massive advantage.  There were a slew of lights which could run rings around their 2AA model for both runtime and output as white LED lights started to become more common.  In fact, there were several commercially produced kits which allowed the popular Mag 2AA to be converted to LED operation that appeared on the market a few years ago, such was the opinion of people that "it's a great light...just wish it was LED based."  The 1AAA "penlight style" Solitaire was all but ground into dust by the likes of the Arc AAA (one of which has been on my keychain now since around 2003 and is still going strong) on account of it's candle-like light output.

It appears however, that they have finally seen the light (pun absolutely intended...) and now have quite a number of LED models available in most of their "Classic" form factors from 2AA upwards (I've no direct experience with these lights yet however, so can't really comment on how they perform), in addition to several new, more original models.  The XL100 reviewed here is quite a radical departure from Mag's usual very traditional approach to design; looking somewhat like a Mag Solitaire on steroids, and sporting a rather innovative switching system.  While I approached it with quite some skepticism, I really quite like it.

Can it really be true?  Can Maglite have really gone and broken the mould...and actually come up with a winner?  Let's find out, shall we...

First Impressions.

This is the first time that I've actually had a chance to look at a product from Mag which is completely new, so it's really interesting to get a look at what their design team can do when they actually drag themselves into the 21st century and make use of all the technology in front of them.

The light comes on a green card-backed plastic blister package as with most of their retail models.  This is a particularly sturdy sonic welded package, and is a complete pain to get into - if you don't have access to a pair of sharp scissors or a craft knife, I wish you luck!  I'd discourage the use of flamethrowers or explosives however, as that would probably void the warranty...

Once you do finally manage to get into the package - and assuming that you haven't sent the light flying off across the room and the batteries scattering in all directions - first thing you may well notice will be how light it is until you put the batteries in.  It doesn't really feel flimsy or anything, just oddly light!  It is a mass produced product, so the fact that Mag have cut down the amount of metal they've used as far as they can without unreasonably compromising the durability isn't all that surprising.

In the package with the light itself is a brief set of instructions (the backing card folds out), and a set of Duracell AAA batteries.  It's worth noting however that these aren't taped in or if you're an idiot like me, they may go rolling off over the floor when you take the light out.

First impressions visually are, as I mentioned above in the introduction, that the light looks very much like a giant Mag Solitaire in terms of its actual proportions and styling.  I guess however that anything with that sort of aspect ratio, a glossy anodised finish and groves running along the length of the body do to some extent though given what a ubiquitous light it is.  I do actually have a couple of them rattling around in a box somewhere...if I can track one down, I'll snap a photo of this light next to one sometime.

Overall fit and finish seem to be precisely what you would expect from a company who've been around as long as Mag and pride themselves on a reputation for making a mass produced, but decent quality product: Overall very good.  There are no rough edges on any machined parts, all threads turn smoothly etc and are properly lubricated, as are the waterproofing O-rings.  The markings throughout the light are all laser-etched and are properly aligned, complete and crisp.  The entire thing appears to be anodized, inside and out, with nothing having been missed. 

The only let down at all is the plastic lens, which on my sample has a couple of marks on it.  Nothing that's the end of the world...but it's still a shame that they didn't apply as much attention to detail to that as they did to the rest of the light in terms of quality control.  First impressions count for a lot, and it's a bit of a shame that a couple of little scratches on the lens mar what otherwise really looks and feels like a quality product.  Still...overall this is a minor detail, and I'm sure that Mag would happily send me a replacement lens if I asked - which I shall be doing shortly.

Powering Up.

As with most lights, this one does not come with the batteries installed - you need to do that first.  It's not too hard though, just follow the instructions below:

1. Unscrew the tailcap (the end with the orange button on it) by turning anticlockwise (if you're looking at it as if reading the text there), and put it somewhere safe.

2. Tip out the battery carrier.

3. Insert three new AAA Alkaline batteries into the holder, negative (-) ends towards the springs.

4. Reinsert the battery holder into the body of the light - there's an arrow embossed (albeit rather faintly) in one side which indicates which side should go in first.  This is the side which has a couple of pins on it, rather than the ring shaped terminals in the centre and a single pin.  If you insert it the wrong way, the light will not operate.

5. Screw the tailcap firmly back on.  That it's you're done.

Runtime testing on this light will take a it has rather a long rated it will have to wait a bit until I've got the odd five hours free to keep an eye on it!

Mag indicate that the light should run for around 5 hours on high, and for around 200 hours on low. 

The instruction manual specifically prohibits the use of rechargeable cells in this light, however I have tested it using a set of rather archeic NiMH cells with no apparent ill effects.  These cells are borrowed from a friend and have now been returned.  I have nothing which uses rechargeable AAA's, nor any way to charge them, so it's unlikely that I'll be doing runtime testing specifically with rechargeables - especially given that the instructions state they shouldn't be used.  In a pinch though if this is your only light and they're the only cells you have appears that they will work.

I'm no great fan of battery holders like this.  Firstly, they make it very hard to change the batteries in the dark, or if you have cold, damp, greasy or gloved hands.  Also, while this one appears to be pretty sturdy, I have seen lights with holders like this where the light has had to be scrapped after a few years because the holder has fallen apart - though even if it did fail, the light does have a lifetime warranty.

One change which I think could be easily implemented which would make this rather more user-friendly though would be to implement some sort of interlock to make it impossible to insert the battery holder backwards.  A couple of the Nuwai lights I have with holders like this have done just that simply by having a tab at one side of the holder at the top.  If you try to slot the holder in the wrong way around, it simply will not fit far enough in to screw on the tailcap.  Given how hard the arrow is to see, I think this would be quite handy, not hard to engineer either.

User Interface.

Okay, this is where it gets interesting.  My usual procedure when getting a new light goes something along the lines of; open package, pick up batteries which spilled all over floor, put batteries in light, switch on, blind self, switch off, examine light, blind self again, write review.  Sometime after the first draft has been written, I may actually look at the instruction manual.  This was a rare case of my actually having to look at the manual to work out how to access the different modes.

If you want to use this light just as any other flashlight, it couldn't be simpler.  All you need to do is press that little rubber button on the tailcap once until it clicks softly to switch the light on, and again to switch it off. 

I, like many other people spent the first five minutes looking at the little notch on the rubber button and being convinced that it must rotate to get to the different modes, and noting how awkward that appeared to be...I was of course completely wrong!

That little notch is there in no capacity other than to act as a frame of reference for which way is "up" as far as the control circuitry is concerned - because you see, this light has a motion sensor built into it; this is the central part of its quite unique, and quite clever control system.

The light has six modes - I'll tackle these one by one below.

Normal (dimming).  Switch the light on with the little notch facing upward and the light held roughly level - but don't let go of the button, while keeping it held down, slowly rotate the whole light to the right or left.  As you do this, the light will get dimmer or brighter, just as though you were turning the knob on a wall mounted dimmer switch for a ceiling light.  Once you reach the brightness level you want, simply release the button. 

The light can be switched off once you're done with it simply by pressing and releasing the botton again as normal.  Next time the light is switched on by a "single click" it will come back on in the last brightness level selected.  Quite a bonus if you're in a situation where you don't want to wreck your night vision, because you can set the light at a low level and leave it there, knowing that when you switch it back on that it won't dazzle you.

Strobe.  Turn the light so that the marking which shows "Strobe" and the three dots is facing upward, then press and hold the button.  The light will come on, and after approximately 1 second will start to flash.  Turning the light to the right or left will increase or decrease the strobe rate, and releasing the button will then set the speed.  This appears to be variable between approximately 0.5Hz to about 10Hz.  It's quite fast enough to create proper stop-motion effects.

Nite Lite. Yes...That is how it's spelled on the light...Maglite apparently can't spell.  Activate this mode simply by holding down the button with that marker facing up, for about a second, the light will blink very briefly giving an indication that the mode has been selected, then you can release the button.  If you then set the light down somewhere stable, after being at rest for around 2 seconds, the light will slowly dim to a very low "moon mode" and stay there.  If however you disturb the light (it's actually quite sensitive) in any way by moving it, it will instantly return to full brightness until it is left still for around two seconds or so.

This is actually quite a clever feature I think, and would be a real bonus if the light were being used in an unknown hotel room for example, or in a caravan or tent where you don't always have a shelf handy in just the right place, or might not be entirely sure where the light is.  All you need to do is fumble for it a bit, and pretty much as soon as you touch it, the room will light up.

Signal.  You've probably caught onto how these modes are activated by now...Yep, this one's activated by turning the body of the light so that the "signal" text is facing upward, then pressing and holding the button.  After a second or so, the light will switch off.  Once in this mode, rotating the light anything more than 45 degrees or so from vertical results in the light switching on.  Returning it to the "upright" position will switch it off again.  This I found to be a little awkward, but works much better if you hold the head of the light in your other hand and use one just to concentrate on rotating the light as shown below.  Still though think that a conventional button is actually easier for this function, and that this may have been included more from a "we have the funcionality to do we will" point of view rather than as a genuinely useful mode.

SOS.  Speaks for itself really doesn't it...I wonder if you can guess what this mode does?  Yep - if you press and hold the button with this symbol uppermost, the light will start to flash out SOS in morse code after a second or so.  Rotating the light to the right or left before releasing the button will increase or decrease the brightness level - but has no effect whatsoever on the speed of the flashing.

It's clear here isn't it, that there is a huge level of versatility here?  The unusual thing however is that it's been implemented in such a way which does not in any way hinder the ease with which the light can be used as a normal flashlight on a day-to-day basis.  You just click the button to get light, and click it again to get no light...couldn't be simpler.

While it baffled me initially, I've come to think that this switching system is really rather clever; not only that but the inclusion of features such as the night light and dimmer are genuinely useful.  I can't see the strobe, signal or SOS modes being used particuarly regularly by the majority of users - though the SOS mode would be a nice one to have I imagine for anyone who goes hillwalking or similar on a regular basis.  Even if you never use's nice to know the feature's there.  The strobe mode I can see being used mainly as a poor man's substitute for an old fashioned xenon strobe light...No doubt students will love it for dorm room parties...but I can't really think of much in the way of practical uses for it!

All in all...despite its complexity, this is a very easy light to use.  Just read the instructions first, because it is quite unlike anything you're likely to have encountered before.


A few years ago, LumiLED's were really dominating the high power LED marget with their Luxeon Star products, first in 1 watt form.  Shortly after, the 5W version came on the scene - despite eye-searingly high lumen levels, this never attained quite the popularity as the 1W models; difficulties in a lot of lights in dealing with the considerable amount of heat produced, and focusing the beam from the relatively large source may well have contributed to this.  The 5W part also had a relatively high working voltage, which further complicated the challenge of creating efficient drive circuitry.  Later on, a 3W version of the Luxeon Star was released - this was actually a more refined version of the original 1W part, with improved thermal transfer characteristics from the die to the outside world.  This was far easier to focus due to the smaller optical source than the 5W version, and was the first serious incandescent beater which I first encountered in flashlights on supermarket shelves rather than just those ordered from specialists.  ...Which reminds me, I really need to review that 3W one which I bought from Tesco last year...

In the last couple of years however, a lot of competetion has now popped up in the high powered LED market, with Cree, Nichia, and ISP Korea to name a few all having products on the market.  The two big boys in the fight though still seem to be Philips owned LumiLEDs and Cree - I'm not going to say who's winning this battle as the moment I type it, that information will likely be out of date.

This particular light is powered by a LumiLEDs Rebel LED which is rated at 1W, however delivers considerably more light than the original Luxeon Stars did thanks to an efficiacy of 70+ lumens per Watt (I can't say precisely what that is, as I don't know what the part number of this emitter is, and it varies by part somewhat from a minimum of 70Lm/W up to a guaranteed 100Lm/W for some specially selected parts).

For all it's not a huge light, make no mistake, this thing is plenty bright enough for any task that your everyday user is likely to want a flashlight like this for.  It's not going to light up that barn half a mile away in the dead of night on your farm when you've heard a noise there...but that's not what it's designed for.  If you want to do things like that, you really want a high power incandescent or HID based searchlight.  For walking the dog on a less than perfectly lit road, wandering around a house during a power cut, working in the loft, or crawling around under the car however, this is more than adequate - even when not set to its highest power level.

While the packaging states that the beam is adjustable...just don't bother!  Adjusting it simply leads to the otherwise surprisingly smooth beam becoming full of artifacts, slightly wider...and dimmer!  The default "fully tightened" position of the bezel results in a good medium spot beam with a soft fall off to the sides - a beam which appears to be a good balance for daily use.

As with most of their existing incandescent products, the bezel of the light can be removed, and the light operated in "candle mode" if you're wanting a broad spread of light to light a room or tent.  I would not recommend doing this however...While it works, it does lead to a lot of glare, as the LED is a very bright point source - and in a room with a light coloured ceiling I would certainly suggest simply standing the light on its end (it has been designed so that it stands quite happily with the reflector facing up) with the reflector in place as usual and working from the light bounced back from the ceiling.  This gives you nearly as much light, but without the blinding glare - it also means tha the light retains its waterproofing and the LED remains protected, as with the bezel removed this of course means that the LED is exposed to the elements.  Unlike "old fashioned" 5mm LED's which have hard epoxy resin cases, the outer of the Rebel LED used as the lamp in this flashlight is actually made of a soft silicone material.  As such, it is quite vulnerable to damage if exposed - and of course it's not like you can just replace the LED like you can a bulb in an incandescent even though you can...I would suggest NOT removing the head.  If you absolutely must, please be careful.

Unfortunately as I do not posess a light meter at this point in time, I can't provide actual figures for the beam intensity, the photographs below however should give you a good idea in real terms I would hope, both with regards to power output and beam angle.

Please note that the off-centre beam above is an artefact of the photograph due to the camera not being perfectly parallel with the target rather than a defect in the light!


Mag have been making flashlights for a very long they should know a thing or two about making them easy to work with.  To be honest, I really can't argue with their previous offerings in that regard, though the Solitaire could be a bit fiddly to use...that's mainly due to the fact that it's so tiny though rather than poor design.

Ergonomically, it is very hard to fault this light, especially if you're using it the way that I expect that the vast majority of users will - and that's in normal (click on, click off) mode.

It's comfortable to hold in a variety of ways, though the button can be a little stiff to press with your thumb sometimes, with the light tending to try to slide through your fingers - so I tend to rest my index finger on the button rather than my thumb, especially when holding the light in a tactical style grip as shown below.

Retention is aided by longitudinal grooves cut into the body of the light, head and tailcap.  While this is helpful when trying to fasten or release the tailcap to replace the batteries, it doesn't actually do a huge amount in terms of helping you to actually stop the light sliding out of your hands in the direction of the grooves unfortunately.  This is especially true if you're only holding it between a couple of fingers, as is quite often the case I find when I'm using a flashlight to peer into some dark, inaccessible corner of a cars engine bay. 
The conventional knurling on the likes of the MiniMag range do a great deal better job of actually keeping the light in your hands I find.

This is compounded by the fact that there is no provision made whatsoever on the light for the attachment of a if you do drop it, it's going to keep going until it hits the ground, gets wedged down the back of the engine block in your car, or goes bouncing off down the mountain path you're walking along. 

On the subject of losing hold of the light...I've managed to lose track of it in my room several times already, including while I was actively trying to take photographs of it for this webpage.  On every occasion this was because it had rolled off from where I'd put it.  ...This light is particularly fond of rolling, and being pretty much a perfect cylinder - it will keep going in a nice straight line until it falls off wherever you've put it.  I have heard that there is actually an anti-roll device available for the 2AA MiniMag which fits over the end of the light - this will apparently also fit on the XL100, which would at least put an end to its Houdini like ability to disappear the moment you put it somewhere more than a tenth of a degree from perfectly flat and take your eyes off it for more than two nanoseconds.

The lack of actual knurling on the body of the light is actually a bit of a bitter-sweet thing, one which more thought may have actually gone into than I was initially giving Mag credit for.  This is a light which is going to lend itself to being carried around in peoples pockets - and aggressive knurling I know from my own bitter experience is very good at one thing: Destroying pocket lining!  This design while less grippy than a light with proper knurling is still a heck of a lot easier to hold on to than it would be if it was just plain, shiny anodized aluminium - but is also pocket friendly.

Please Maglite, if you're reading this...when you release a new version of this light, give us a lanyard attachment point...and if at all possible, use that as an anti-roll device too.

Now, using the different modes...Being at least to me a completely new interface system, I had to experiment a bit to find a properly comfortable way of using it.  You'll quickly find a combination that works though, the different options I've shown here are just those which I tend to use myself.

It's by no means impossible to do this one-handed holding the light like in the next picture, but you may struggle with this slightly if you've got weaker hands, as it does take a bit of effort to maintain the pressure on the button, hold the light in your hand (bearing in mind its tendency to try to slide out of your hand when you press the button), and then twist your wrist to rotate it.  While it's an innovative system...ergonomically speaking, it's not perfect...Comparing it though to some other control systems I've seen on multi-mode lights, it still gets the thumbs up I think.

Durability Department.

Now this has always been the party piece for LED lights, as the actual lamp itself is for all intents and purposes, impervious to shock.  Assuming that the body is up to it you could literally play football with an LED light and it would not care in the slightest.  ...Well, you'd have to work out some way to make it roll and bounce like a football I guess as well...but that's just being picky...

Durability wise, Mag's only ever really had one real issue, and that was the simple fact that they were based on tiny little xenon incandescent bulbs, which were obviously by their very nature quite sensitive to shocks.  Dropping a light onto a hard floor for example would more likely than not result in a popped bulb.  The actual build of the lights though has generally been very good - one reason that they have long been a favourite for modders to use as a basis for one-off lights and for upgrade packages.

Based on this history, and my first impressions of the light itself, I don't forsee it having any issues.  Still...let's see if I'm right!

The anodizing on this light I would have expected to be type 2 hard anodizing, which is a bit harder than most paint finishes and doesn't flake off in chunks as paint will tend to when scratched.  Attacking the area underneath where the bezel screws on (so it's out of sight!) with the tip of a key left a small scratch, which confirms this suspicion.  This is a pretty hardy finish which on a light which is used around the house is likely to look like new aside from the odd nick for years.  If it's kept in a toolbox or something though, it will wear away quite quickly - though this will not in any way affect the functionality of the light, it will just mean that it looks a bit more beat up.

The weak component in terms of the outside of the light I am certain is the lens.  This is made of pretty soft plastic and is quite thin, if anything is going to get scratched up badly even in gentle use, this is it.  If this is a real worry for you, or your lens does get badly scratched up, a few sources I've found online have indicated that the glass lens for the MiniMag 2AA will fit correctly in this light (part #108-617).  The only worry about that however, is that the lens in this light is held in place by the reflector - this is a pressure fit inside the head.  This means that to get it out, you have to apply pressure on the lens, and wobble the reflector from side to side in a highly technical manner until it drops out.  Given that it really is quite a tight fit in the head, there seems to be quite a possiblity that the reflector could be damaged during this if you do decide to replace your lens, please be careful.

The second potential weakness which would spring to mind would be the rubber boot over the button on the tailcap.  This actually appears to be made of pretty tough rubber, so I think will stand up to normal levels of use and abuse without any problems.

While the metal that the body of the light is made of is not hugely thick, being honest it doesn't really need to be.  This is a flashlight which is designed to take the rough and tumble of everyday life, not a military grade light which has to be designed to take a trip to Hell and back via the bottom of the Laurentian Abyss without any possible chance of failure, and that needs to be kept in mind.  As far as domestic lights go, this thing is sturdy - I'm not about go go running it over with my car as I am sure I could easily do with some of my other lights, as I suspect it may not stand up to that - but I think you're going to have to do something pretty special to actually damage the body.

The one concern which some people seem to have raised regarding this light is with regards to the motion sensor in this light, and whether it may be susceptable to damage from severe shocks.  A number of other reviewers however, and a couple of threads on Candle Power Forums seems to suggest however that this component is actually a lot hardier than we might have expected and actually very seldom gives trouble.

So, let's do the usual shock testing and such then...

Whacking the light firmly against the side of my desk, five times against the tailcap and five times against the bezel, aside from a funny look from someone outside at the noise didn't do anything at all other than leave a dent in the side of the desk.

The "dropping from waist height" test is really just a the light has rolled off my desk at least five or ten times already and survived!  This was done in the kitchen as a test as it has a tiled floor - the worst enemy of anything vaguely shock sensitive as it is so completely unyeilding.  It shrugged it off without any problem whatsoever.

The third and final kinetic energy test was done on a thinly carpeted wooden floor, when the light is thrown with moderate force across the room from waist height, as if to emulate the light slipping out of your hand while running.  This was repeated three times with no failures to report.

With regards to water resistance, the light is advertised as water resistant, not waterproof.  This means that it's intended to survive getting wet, but isn't intended to actually be submerged.  All components were tested and found to hold a vacuum, however reports have indicated that if the light is submerged that water will tend to very slowly seep in around the perimeter of the lens - the only part of the light which is not visibly sealed with an O-ring.  The light was left laying on its side in the shower for half an hour to emulate a reasonable length walk in a rainstorm - afterward there was no sign of moisture found within the light.  So while I would suggest against going swimming with it - this light seems to be quite capable of surviving a trip out in the rain.  To ensure that this remains the case, make sure that every few months that you lubricate the O-rings with a silicone based lubricant - no need to use too much, just a couple of drops will do.

I am quite confident that this is a light which will pull all the punches that everyday life is likely to throw at it, plus some more to be honest.  Just don't go diving with it.


As I said at the very start of this review, it was one which I was approaching with some trepidation.  Especially in light of the switching system which sounded from the packaging very much like a gimmick which was going to be completely useless in the real world.  I was however willing to give it the benefit of the doubt and try it.

I think in all honesty that Mag have a product here to be proud of.  They've managed to pull off a fantastically difficult feat, which is designing an interface which manages to give access to advanced features, but does it in such a way that they do not in any way, shape or form get in the way of day-to-day use of the light.

It's bright, it's got a perfectly balanced beam, it's comfortable to use...C'mon Mag - give us a decent lens out of the box and a lanyard attachment point and you'd have a perfect light here...

Well done guys!


+ As close to a perfect combination of advanced/basic features as I've ever seen with an interface that works.

+ Bright for its size.

+ Very usable beam pattern.

+ Uses cheap, readily available batteries.

+ Comfortable to hold.


- Poor quality lens, completely at odds with the rest of the light. (There goes two points)

- No anti-roll device or lanyard attachment point (one of these two would drop it off the cons list...but a lack of both leads to a potential for the light to get lost!)


> Night Light mode always jumps to full power - it would be nice to be able to set this to a preset level to avoid completely zapping your night vision the moment you touch the light.

> Battery holder is fiddly to change in the dark or with cold/gloved hands.

> Shame that it's not fully waterproof given how little extra work it would take.
