Tailcap O-Ring 108-207 Lamp Protector 108-037. Battery Spring 108-032.Available in black body color only.This is for the flange style bulb only!
- Streamlight also produced a plastic SL-15 model and an aluminum 5D cell sized SL-35. The 3D sized SL-20 was the most popular of the bunch. The SL-20 soldiered on for around 10 years. In the mid to late 1980s the SL-20X was introduced as a new and improved model. Original SL-20s are easily identifiable because they are stamped SL-20 behind the.
- If you find Maglite 3D LED lights with an extra bulb and the serial number does not start with DL, it’s an older model. Current 2012 models have 015 printed next to the LED, and 2011 models have 483 or 484, so you will need to physically look inside the packaging to confirm which model it is.
Since 1979 Mag Instrument has been dedicated to finding ways to cut costs through manufacturing efficiencies instead of raising prices on their lights. Throughout the 1980s Maglites remained largely unchanged except for minor cosmetic differences. That changed in 1990. By 1992 the light's design was completely overhauled into the flashlight that's currently available today. In this post I'll discuss the 1990 and 1991 model lights. Most collectors refer to these as 'transitional' models. Before I start it should be noted at all parts interchange between the 1991 and prior models even though the aesthetics changed slightly. This is not the case with 1992 and later lights where most parts will not interchange. Shown below is a 1991 Red Transitional 5D and a 1983 Black Vintage 5D. I'll discuss the differences shortly.
One of the changes that started in early 1990 was that the light's grip size was reduced. The grip size was reduced due to the fact that the grip near the end of the flashlight went largely unused as most users held the light near the switch or in the middle for a better balance point. The decision to reduce the grip saved on production time and tooling costs. Grip sizes were reduced according to the table below and the grip length was standardized to it's currently available length. Also shown below is a picture comparing two 3Ds. The top one is a vintage light that is an example of the 1989 and prior models and the bottom one is a 1990 that is a good example of 1990 and 1991 transitional lights. This picture show the overall reduced grip length. This change makes it very easy to spot the older lights on everyone's favorite auction site or in photos. Along with the bezel style it is a very useful tool in determining the age of a Maglite without knowing the serial number.
In addition the switch style was also changed. Up until 1989 the switches used an aluminum retaining ring that screwed into the inside diameter of the light and held the switch in place. Starting in 1990 Mag Instrument changed this to a plastic retaining ring and it is now the only style available when ordering replacement switches for older style lights. I've detailed the benefits of this change in my post on removing stuck retaining rings. I do have a large collection of NOS (new old stock) metal retaining ring switches that I use for restorations so I can use the correct switch for the light being restored though. Shown below is a picture from that thread showing the difference between the switches. The older style switch is on the left and the newer style switch is on the right.
These 'transitional' lights kept the same barrel size and non-letter serials as the pre 1990 lights. In 1992 the Maglite was completely re-designed into the model that's available today. Details on those changes can be found here. Most collectors regard the 1991 models as the last year of vintage Maglites and some even regard 1989 as the last year. I have several 'transitional' Maglites but they are not as collectible as earlier lights. In fact most folks confuse these with the 1992+ 'Panther' Maglites because they look so similar. I enjoy these lights because they still have the larger barrel even though they may be some of the least collectible Maglites.
Colors were very limited on these lights. This was mainly due to the fact that Mag Instrument was starting to modernize their facility and starting to build new tooling and assembly lines for the switch over to the redesigned lights in 1992. I've only seen these in black, red, blue, and silver. Serial numbers are going to be around the values listed in the table below as I have examples of each D cell transitional model and they were only produced for 2 years.
It is interesting to note that these serial numbers are also the production numbers of each model D cell up until 1991. So, in around a decade 4,000,000 3D Cells were produced. This is a good example of how popular, or unpopular, certain models are. I've always been curious as to why Maglite produces a 5D seeing how close in length they are to a 6D and 4D and how unpopular they are. I posted a D Cell Quick Dating Guide that shows round about serial numbers for each model and the above table can also be used to guesstimate the age of your light. Production numbers were low in 1979 and 1980 but were pretty constant throughout the rest of the 80s. Of course, Maglite can tell you the exact date your light was manufactured if you send them an info request on their web site. It's also interesting to note that in the 90s some model Maglites sold in these numbers in a single year. For example 3Ds would easily sell 2,000,000 a year or more in the late 90s. This puts into perspective how rare the 1991 and prior lights really are.
As always I'm looking to buy Vari-Beams and Vintage/Rare Mags. Please let me know if you have any, top dollar paid.
Most of us probably have a Maglite of some sort sitting around the house. Known for their superior build quality and durability, Maglite is considered to be the everyday premium flashlight. We will be taking a look at Maglite’s LED line of flashlights featuring the latest Luxeon Rebel LED.
Form Factors
The LED Maglite is available in several form factors and with two kinds of LEDs, and the type of LED is something that should be given some thought as there is a significant difference.
LED
Older lights are frequently still seen on the shelf, so the kind of LED should be noted. The current LED Maglites use the Cree XP-E LED, and previous generation LED Maglites use the Philips Lumileds Luxeon Rebel or Luxeon III LED. The Cree XP-E is brighter and more energy efficient than both Luxeon LEDs, however, older models are often mixed with new stock on retail shelves.
The Luxeon III (left) is larger than the Luxeon Rebel (right). The Cree XP-E is mounted similar to the Luxeon Rebel, and the main difference is the square base of the XP-E. The only way to differentiate between the models is to look down the business end of the light through the clear plastic packaging.
With the D-cell lights, the serial number also indicates the type of LED inside. If the serial number begins with DLXXXXXXXXX, it is either Cree XP-E or Luxeon Rebel. If the serial number begins with DXXXXXXXXXX, it is the Luxeon III. Also, if the packaging mentions interchangeability with incandescent bulbs, then it is the Luxeon III.
Sizes
Here’s the breakdown of the sizes that are available based on LED type:
| Luxeon III | Luxeon Rebel | Cree XP-E |
| 2 AA | 2 AA | 2 AA |
| 3 AA | ||
| 2 D | 2 D | 2 D |
| 3 D | 3 D | 3 D |
| 4 D |
The 2AA light is an exception and is actually available in three different form factors. There are two types of the 2AA with the Luxeon Rebel – one with the flat tail cap (old), and one with the lanyard tail cap (current), similar to the regular 2AA Mini Maglite. The lanyard tail cap is preferable to the flat tail cap due to increased reliability, as well as compatibility with regular Mini Maglite tail caps (making aftermarket accessories such as “clickie” switches usable).
A common question is 2D or 3D? The gist of that decision is personal preference. The 3D is a hefty light, but it has, by far, the longest runtime. The 2D is more compact, but runtime is shorter due to the need for voltage boost. The difference in brightness between the two is not very significant, so considerations should fall on runtime and size.
Pricing & Ordering
Compared to other premium flashlights, Maglites have one major advantage – local availability. At the time of writing, regular price for the 2AA is usually around $20.
Frys and Lowe’s also sell the lights online, but after reading the previous section, you will know that ordering online is not a good idea. I was able to pick up several 2AA lights for about $10 each, at Lowe’s and Home Depot during the year-end holiday sale.
The 2D and 3D models are a little more expensive, at around $30 for either. If you are a Costco member or know someone who is, Costco has a 2AA and 3D twin-pack that is a great deal for $29.99. Again, prices vary by time and location, so this should only be interpreted as an estimate.
In The Box
For the 2AA, included in the blister packaging are: Maglite LED 2AA flashlight, 2 x AA battery, and belt holster.
For the D-cell models, only the light is included.
Batteries
While the 2AA includes two alkaline batteries and the instructions specify that only alkaline batteries should be used, it is not recommended to use alkaline batteries. The reasoning behind this is that no matter the brand, alkaline batteries can and will leak! If the light is stored in extreme conditions, such as in the glove box of a car, the chances of leakage are much higher. Instead, lithium primaries or low self-discharge (LSD) NiMH rechargeable batteries are better alternatives.
Lithium primary batteries, such as Energizer Advanced or Ultimate Lithium, are more expensive, but last longer than alkaline, perform better in cold temperatures, do not leak, and are approximately 1/3 lighter than the average alkaline. The voltages of these batteries are also slightly higher, which leads to increased output compared to alkaline.
LSD NiMH rechargeables, such as the Sanyo Eneloop that popularized low self-discharge, are able to retain charge up to one year. One thing to note about LSD rechargeables is that Duracell Pre-Charged rechargeable batteries that have a white top on the positive end are re-packaged Eneloops, and these are preferred over the black top counterparts. If you’ve ever used rechargeable batteries, you’re probably aware of the extremely high self-discharge rate that could leave the battery half-empty in a short amount of time. LSD rechargeables are an investment that will definitely pay itself off if the light is used frequently.
Maglite Serial Number Search
For D-cell lights, options are more limited, and quality alkaline batteries are a good choice. Rechargeable LSD NiMH D-cells are quiet expensive and difficult to find, though AA to D adapters can be purchased online so that primary or LSD AA’s may be used. Some adapters offer the ability to hold 2 AA’s in parallel, which will greatly increase runtime. In addition, 2 AA’s will be lighter than a D-cell.
The Light
Head
The head features a plastic lens and a smooth reflector. The beam can be focused with a quick turn of the head, and the D-cell models feature continuous cam action so which direction the head is turned will not matter.
For the 2AA model, brightness will decrease beyond a half-turn due to increased distance between the LED and the reflector, but the head can be unscrewed all the way and the light converted into “candle mode”
Body
The entire light is type-II anodized aluminum inside and out. The anodizing helps prevent corrosion, and also electrically insulates the light. (Picture below shows lights with optional anti-roll ring accessory.)
Maglite Model By Serial Number
The 2AA light sports a multi-mode switch with four modes: 100%, 25%, blink, and SOS. If the light is needed for an extended period of time, one set of batteries will last for more than a day on 25% mode.
The D-cell lights feature a three position on/off switch: momentary, on, and off.
Tail Cap
D-cell lights with the Luxeon III will have a spare incandescent bulb in the tail cap. For the Luxeon Rebel models, the tail cap is not very interesting and consists of only a spring.
Performance
If you’re an incandescent Maglite user, you will certainly be surprised with the output of the LED Maglite. LEDs give off a cool white color, do not generate as much heat, and are brighter. As with incandescent Maglites, the larger models can be used as a baton if needed, although using the head as the striking surface would not be best as the LED cannot be replaced like a bulb! Below are some beamshots of the lights in spot focus:

All of the LED Maglites are regulated, which means that as the batteries are depleted and voltage drops, more current is drawn from the batteries to offset the lower voltage, resulting in consistent brightness until the batteries are completely depleted.

Accessories and Upgrades
Check Maglite Serial Number
Maglite offers a decent variety of OEM accessories for their lights, ranging from belt holders to lamps to traffic wands. I purchased a D-cell and an AA accessory pack, which came with a rubber anti-roll ring that also protects the head and lens from scratches when set down head-first, as well as a set of red, blue, and clear lenses. The D-cell accessory pack also came with a pair of mounting brackets, which I found to be convenient for storing the light. The mounting brackets are quite firm and the light snaps in with a solid THUNK.
For those with incandescent Maglites, Maglite offers a 3W drop-in LED upgrade for the 2-cell, 3-cell, and 4-cell C or D lights, which uses the Luxeon III LED. This upgrade is being discontinued due to the older LED used, but there are aftermarket upgrades (including some with the Luxeon Rebel LED) available from manufacturers such as TerraLUX. For Mini Maglites, there are no OEM upgrades, but TerraLUX and Nite-Ize make 1W LED upgrades that will certainly improve the light’s usefulness.

Conclusion
These lights are certainly quite handy to have around! The size of the 2AA makes a great every-day carry (EDC) light, or could be handy to keep in glove boxes or emergency kits (with lithium batteries installed, of course). Whether you’re an avid outdoorsman or just wandering around the house late at night trying to find your bedroom, these lights are great value and will come in handy, ready for action, for years to come.
