On the inline parallel adapters, best thing to use if you're tight on space is a tailcap switch PCB, with all the vias drilled out so all contacts on both sides are completely isolated. Then attach the double-L pieces. But if you're only doing 2 cells in a 3D Mag you'll probably need quite a bit of spacer... you can squeeze in THREE cells in parallel into a 3D if you use the PCB trick and are careful about the dimensions! (and hack the hell out of the tailcap)

Thank you for the credit on that again. I know you were thinking about doing something similar and it seems that someone has probably had to have done something similar in the past. But it does feel good to contribute something that others find useful (Like what the OP did contributing this thread). I have to give you big props though for taking it to the next level. You did a sweet job on that. I have even seen pictures of your version in other threads. I’m glad about that though, because I cringe when I think about that first prototype I made with the foam divider. That would be a short waiting to happen if someone copied that version.

I have done a similiar mod to one of my favorite flashlights.
It’s an old 2xD Metal flashlight from seagull which I have since I was little.
I ordered some different 12V bulbs after seeing this thread and decided last week to test out which fits best.
I used this LeD bulb(ordered from focal price or so) http://www.fasttech.com/products/1263200 I also paralleled the LEDs but wothout the drilling i just desoldered one wire and bend it up, the leds were clamped down with the optics anyway.
I used a 1A regulated driver to power the LeDs up
http://www.fasttech.com/products/1143101
This gives nice amount of light trough full voltage range. Tailcap current is too much for D Batteries, approximated runtime 2 hours….

It almost fitted perfect just the lens could be one millimeter wider, I have for now used a tiny bit insulation tape to clamp it with the head maybe I will find some clear foil or so…

I like the light and the beam is a nice as shown above (maybe even a bit better than the 3 LED bulb I have here too)

I had to made a battery contact and some soldering like always and it’s not very neat as I want to test the silicone adhesive I had ordered from fasttech but it works.

I recycled an old PCB for the positive contact so there are some pads missing… But it works and was done quickly. Soldered the negative wire direct to some copper from the switch mechanic. Some kapton around to protect from shorting something.

Are the spare bridgelux emitters from fasttech much brighter(two times)?

The bridgelux from FT are a very cool white. They are definately brighter, yes maybe twice. I would be concerned with leaving one lead unsoldered off the star as it is very important to have good thermal contact from the base of the led to the star. These modules only rely on the force of the TIR optics pressing down on the led after the face plate is screwed down for physical (thermal) contact. I soldered mine onto the star, that is reflowed the base to the star.

On second thought having one lead unsoldered to the star will a least allow the led to “pivot” on the soldered end when the TIR presses down on it and not lead to a situation where the led is permanently bridging the pad if it is not soldered properly.

Yes I thought about these theoretical problems, but since 5 of these small LEDs cost less than a dollar I risked it and it works flawlessly. I didn’t understand the last part, one leg is soldered to the star the other leg is soldered to a cable no bridging possible as there will be no movement.
Thanks for the info about the bridgelux, then I won’t order them I like the warm white tint and the output is usable.

It would be fun if we could find a reflector which fits in the mr16 alu, to use it with a single XML or so…sadly I killed the stock reflector :_(

How much current do those draw? Pretty cool looking

They pull about 20mA at the moment but I’m going to be getting some 2mA LED’s soon to swap them out with!

WOW. That’s quite some budget mod we have here! Cool!

I noticed these when searching for the 3W x 3 LED 12v bulb.

Could this be plopped into a maglite as well? Same dimensions as the other bulb. I can’t seem to find an example of what it would look like, but I’m assuming it’s just pure flood. They seem to go for the same $1.50 – 2.00 price as the 3W x 3. I figured it might be worth a shot at that price unless someone knows it wont work without a ridiculous amount of modification.

The real issue though is can you either run the bulb with 12v as is or splitting the LEDs to run on less as I did. The fact that there is a total of 18 LEDs is encouraging as 18 is a multiple of 3. If you can pick one up for $2 go for it. If it doesn’t work out, what have you lost? Remember you don’t have to mod the Mag in a non-reversible way. In other words, you can restore your Mag to it’s original condition.
Yes it would be pure flood. I use mine around the house, great for looking for stuff.

If you modify the traces in the 18LED light with cutter and drill the PCB might look ugly and this has no lens which hides it…

If you want a flooder and it doesn’t work with this light you could also remove the PCB and use a normal cree leD without optics maybe a driver, this will also make flood. But it will make the mod some hundred percent more expensive… :bigsmile:

The 3led modules are quite nice and make useable beam and colour.

New style available. Metal plate is gone.
Looks quite a bit nicer imho. More finished and clean.
US $2.31 MR16 12v warm white led bulb SCA-1156

Pictures show the combined triple TIR snaps into the heatsink with 3 tabs. Should come apart without an issue.

Appears to be the same size and all. Seller: “48 × 48 × 50mm”. Each TIR looks larger tho. There isn’t dead space around each TIR like in the metal plate bulbs.

Listing title says 3W, but detail says 3 × 3W LED.

I think it looks nicer too.

If you do decide to, pick one or a few off ebay. The chinese sellers have buddies/alt account who auto bid up to about $1.40 ish, meaning if you bid last minute for around 1.50 then it’s yours. Smile

I grabbed two 9W MR16 12v 3×3W Led Bulbs about a week ago for about 1.50 each (1 cool 1 warm). If all else fails I get some uber cheap components to fry for experience. Big Smile

It does look better! I wonder if I can just swap my stars over to the new host. I had upgraded the 2 lights that I have done to 3×3W by ordering 3W emitters from FT. The second light I did was a 2C Mag and I run it off a single 18650. That’s the light I use around the house.
EDIT:
I ordered one, let’s see how long it takes to get here

Good find Helios! Can’t wait to see how this one turns out for Ya’ll!

I just finished this mod on my 3d mag I’ve had around the house for years. Love the outcome!
IT was pretty straight forward. Now I gotta find a brighter white than the 3000k I ended up with.
(and make it brighter! of course!)

What about batteries? What are the best combinations, suggestions? (I just put the D primaries in for now, but want rechargeable fun!)…Have alot of 18650’s on hand and ton o AA duraloops…

If we use a 9w like OL found, how does that change the battery scheme? THanks

….just one more….

Nice find Helios.  Looks like one could make the flashlight waterproof using that one.  Or, at least, more water resistant.

Got mine today!  Ordered Nov 4th, delivered today Nov 18th (no tracking China Post).  The two I ordered look slightly different - like the TIR's are different angles.  No thermal paste under the star, but otherwise decent.  TIR snaps out very easy (but not too easy).  Did not test for output yet.

Few pics:

Two side by side to see their differences:

Thanks for the update Garry.  Is the one on the right in the last picture further back?  It appears to have a smaller diameter

How come you got yours first? Oh yeah, PA is a little closer to China than CT. Sad

Ordered mine a week before Garry and mine aren’t here. Sad

I wish their dang shipping estimates were reasonably accurate.

Left one looks almost like an overall larger diameter. :~ Same size in reality, right?

Just checked again, they are perfectly identical in size.

He he he!!!  With unregistered Post you never know what's going to happen!  Actually, I placed an order for some 110v E27 base ones the same day (which came with tracking) and they also came today.

So I overlooked a key factor here… There’s great detail on how to wire the leds in parallel, but not how to physically connect the lamp assembly to the maglite switch assembly.

Can someone guide me to the light?

I too am curious how dchomak wired to the Maglite switch.  BTW - I've done nothing with my bulbs.  I'm just too busy to get to this and I don't even have a 3D Maglite yet.
