TerraLUX TLE-310M-EX MiniStar31M-EX Conversion Kit for 4-6 D Cell Maglites

The TerraLUX TLR-310M-EX is the World's brightest upgrade for 4-6 D cell Maglites! Turn your Maglite into an amazing search light that will trump anything in its class! Lightstar Corp. has revised their popular TerraLUX TLE-300 design with a new and improved upgrade. The MiniStar31 now outputs up to 1,000 lumens and has a selector switch so you can choose whether you want it to operate in single mode or multi-mode.

Single-mode has typically been the preference of police officers and tactical users that want momentary light with full brightness when they need it. The Multi-mode has traditionally been favored by outdoor users, such as campers and hikers where the lower brightness levels can greatly extend battery life while still giving off suitable levels of light. Now you can choose either mode by using the selector switch on the upgrade.

The MiniStar is easy to install; it's as easy as changing a light bulb!

This upgrade only works with incandescent Maglites and NOT LED Maglites

  • Fits MagLite® 4-6 D-Cell flashlights (Does NOT work with C-Cell flashlights)
  • Multi-mode function: (High/Medium/Low), user configurable to single mode via a switch on the side of the module

A Real Step Up For Your Maglite
The TerraLUX MiniStar31M-EX LED Conversion Kit works as advertised and is a big improvement over the stock Maglite output. The only downside is cost, you can buy a better flashlight for the same, or less money; however, if you are like me and cannot bring yourself to throw away the old Maglite, upgrade it with the Ministar31M-EX LED. I converted a 2 D cell maglite with this unit and a pair of Titanium Innovations Battery Adapter that Converts 3AA Cells to 1D size - in SERIES and outputs 4.5V; it works great. Now I am going to upgrade my dad's old 4 D cell light with the Ministar that arrived yesterday.
ProsGreatly improved light output

Nice conversion
I have 2 of the 4 D cell Mag-Lite units. When the Terralux conversion kit arrived I tried it in one flashlight and it did not work. When I tried it in the other flashlight it worked. There was a slight difference in manufacturing of the 2 flashlights. I like the multitude feature that saves the batteries when full brightness is not needed. In the full brightness mode I could see clearly over 100 yards away.
ProsBright, works well, easy conversion, continue using my old flashlight.

Makes a "Light Bazooka!" out of your old 6 D cell Mag Light
This is incredible! This was the first really, really bright light set up that I had and it breathed new life into an old, dim (in today's standard) 6D cell Mag Light. It's a Flaayayayam Thrower, Baby (umm, that's an old line from a J. Geils Band hit from when 6 D Mag Lights were "state of the art", sorry...) These are WORTH it for what the do for an old Mag Light.
ProsAllows updating of an old classic
ConsThey are not exactly giving them away (but they are worth it)

TeraLUX 1000Lumen Conversion
Works great and really throws the light! I initially had a bit of difficulty installing the unit, but after re-reading the instructions a couple of times (especially step 5) it finally became clear that the unit has to be lightly screwed into the flashlight and is not just a drop in unit!

A great LED replacement for 4-6 D Cell MagLites
Great and easy replacement.
ProsVery easy use and great functionalities: if left in the default auto mode, at each click the torch cycles the three power levels.
ConsJust a couple of minor issues: on my 6D I had to figure out that I had to manually pull a bit the former fitting of the lamp since it was retracted and the replacement could not reach the thread; eventually the fitting of the replacement and the fitting of the MagLite head had to be fine-tuned to have the contacts working properly.

ProsBrighter than bulb & longer battery life.
ConsLittle pricey

I need one of these for each of my 4D+ Maglites
I bought one of these quite some time back, plus a few of the earlier 500 lumen & mag charger versions. Now that I see Battery Junction also sell the "Bust O Caps" and I can re-purpose many of my old 4D mags I think I will get some more in the near future.
ProsPerfect complement to an awesome piece of vintage equipment that is often lacking in the modern lumen stakes. Sure you can get more lumens in smaller lighter (even cheaper) package now days but can you use a smaller unit to defend yourself - smash a window - use as a lever - chock a truck wheel and all the other things I use and abuse my Maglites for (other than light). Love my upgraded Maglites.
ConsA bit pricey but at least provides a new purpose for my old Maglites. You must have the correct vintage Maglite, it needs to have a "D" at the front of the serial number. Some of the later Maglites also may not accept but all mine with the "D" in the serial number take these upgrades.

It works on bi-pin Maglite
I give this 4 stars as an initial rating. I gave it to my dad for Christmas. He has a 4D Maglite with the newer bi-pin bulb. It does work, you have to unscrew the collar that holds the new bulb. To change modes I have to double-click when it\'s on. I find medium to be a too high, but overall I like it.

Doesn\'t Fit New Maglitesl!!!
I purchased this kit to use in my older 4 D-cell Maglite only to find out that the kit doesn\'t fit my old light. Okay fine, that light is from 1980 - the dimensions have changed slightly since then. So, I went and bought a brand new Maglite - well, the new ones have Xenon bulbs that don\'t screw in at all, but have two tiny pins that fit into two tiny holes where the socket used to be - nowhere to screw in a bulb, no way to retrofit. AAARGGH you\'ve got to be kidding me!!! BUYER BEWARE, THIS THING ONLY WORKS WITH OLD HALOGEN MAGLITES, BUT NOT TOO OLD!!! Returning this item.

Nice improvement
Now have three MagLite 3D flashlights. Using these bulbs; TerraLUX - MiniStar31M-EX - Very bright TLE-300M-EX TLE-6EX MiniStar5 All lights are powered by 14500 Trustfire Li 3.6volt batteries. @ 10.8 volts total. 900ma batteries. Two of the lights have (3) 2AA to D adapters - Plastic with 6 cells total.@ 1.8 amp. The 31M unit has a custom 9AA adapter, paralell config., @2.7 amp and very nice. Not cheap like the plastic adapters and I think well worth the price. Well built. I use a bulk charger on that one. Ordering another MiniStar31M-EX for a friend now. (had to have one after he saw mine :))

Came just for Christmas
Ordered the 18th december. Got an email as it wasn\'t in stock. Has been backordered to the 23th. Finally the 21th it has been shipped and came at home today. First impression. I saw that the packing was cut and then sellotaped where the connexion is. I guess batteryjunction done it for verifying the led upgrade was fully working. Good point. Heard about the fact that there was a possibility of lacking heat compound underneath the leds. This isn\'t the case. Works well in a maglite 6D with 2200 mAh NIMH Duracell cells. Current drive is around 2 A for high, 0.9 A for med and 0.1 A for low output. These batteries can handle it. This does a maximum consumption of around 16 watts max. For the light in itself. It\'s quite powerful. Will once compare it with the Fenix TK41 of a friend. From now I can only say the spot is larger there than on the TK41.

Finally Finally Finally
I got to see one today! I am impressed I have a 700/600 6cell D size light. I was so happy to finally get a chance to see one today. I was not sure if the difference between 600 and 1000 would even show up during the day time but it does and if it does during the day I know what will happen at night. Dang I am impressed big time.. dray I bought one does that say something. and I still have my 700 lumen one around, so I bought another maglight to go with it.

You can use this upgrade in a 3D mag or even a 2D mag as I have but you need to put together a custom battery configuration to get required voltage. If interested read the many things that can be done on Candle Power Forum. If not then stick with something simple.
