What did you mod today?

My latest X6 Quad.

For this quad build, I used a 35mm Ledil "double dome" optic.

As you can see in the photo, it's shorter than a Ledil Cute optic, 9mm vs 15mm, so I'm going to have to add onto nitro's custom copper heatsink. It's design also does not allow for a glass lens in front, so I'll have that much more to raise it up.

Shallower reflectors than the Cute optic. I'm not really sure how that affects optics.

The domed top fits perfectly in the bezel, preventing any side to side movement.

The raised dome looks very professional.

Time to start. Time to start cutting copper. I don't measure, I just start with the thickest stock I have and keep adding to it until it's the right hight. Luckily I had some 10mm SinkPads handy, I'm going to need them.

Cutting and filing is all part of the process. It was around here that everything went south, but that's a separate thread. I recovered.

This should do it. Nitro's heatsink topped with my own, and what will be the emitter plate.

That's a lot of mass. This light will be top heavy, but well heatsinked.

This is the part where a complete failure is most likely to occur.

A wise person would safely affix the MCPCBs to the emitter plate with thermal adhesive, but not ouchyfoot. No, no, no. He wants to solder them down.

The problem with soldering, is that you need to leave the optic in place during the process so the emitters will be perfectly aligned with the optics.

...solder paste melting temperature vs optical plastic melting temperature. Place your bets now!

Here are the emitters and optic aligned with the emitter base. I'm going to the use hot air reflow from the underside to solder down the MCPCBs

Five different things could happen here, and four of them are bad.

Whew. All went well. I was taking into consideration that these optics can handle a bit of heat, and the fact that they were resting on top of the substrate, not the copper.

I originally planned to use XP-G2, but when I looked, I only had three, so I had to go with the Nichia 219C.

All wired up with 22AWG Teflon wire and a BLF A1 driver from BG.

This part is crucial, and had to be done last.

Without the legs of the optic connected to anything the only thing holding the optic in place are the domes of the Nichias. The slightest bit of pressure and tork when tightening the bezel is guaranteed to rip them right off, so I need anchors.

I used some of the copper tree the SinkPads were attached to so the hight would be the same. Drilled some holes and snipped them off.

Sanded them down to usable and unobtrusive size.

I got everything lined up so I could affix them in place with Artic Silver epoxy. I used a clamp to hold the optic down tight a left overnight to cure. There is no turning back here, as the optic will also be epoxied in place permanently. There was no way around it, which is why I left this part til last, after the emitters, heatsink, wiring and drivers were completely installed and tested.

Fits nice.

Comparison with another X6 with a flat Ledil Cute optic.

Yes. It works.

With my DMM I'm getting a tail reading of close to 9A with Samsung 30Q. Pretty much the exact same reading as my X6 triple 219C.

This baby can handle a lot of heat.

Is it bright? Of coarse it's bright? What did you expect.

Floodier beam than the triple.

This is all the typing I can do as my fingertips are bloody and sore from filing and sanding. I had more to mention, but I can't remember now.

Keep up the modding people.

I’m willing to bet it’s doing way over 9amps, your DMM is probably limiting it. My clamp measures my quad 219c at 16 amps, and dale has reported them over 20amps. (on 30Q)

I kinda figure that too. I've seen all the other readings and mine always seem lower, and I don't skimp when it comes to ferreting out resistance. Even my springs are double copper braided. They sure put out a lot of light though.

Well, I put an Xhp70 into an ultrafire 1226. I had to machine a copper heatsink for the LED board to sit on, but it’s pretty bright!

Tripled a new style S3 and replaced led in H20. May have to go camping tonight

What I thought was going to be a quick switch replacement on my CNQ "Brass Beauty" took a little detour... Turns out the switch was fine, but the way it's mounted is like in the cheapo ~$5 lights, with one switch tab jammed against the inside wall of the cap, & the other tab folded under the switch, tucked in between the last coil of the spring.

I couldn't just put it back together after seeing that, so after a little fiddling & drilling, I ended up with a proper soldered switch, with a little 'bling' to boot! :)

Wauw!

And I am extremely happy
Remember that Ultrafire C8 I baked to a nice copper color?
The AK47 driver I wanted to use got jammed while a wire broke off
Today I got it out. Didn’t trust it so put the BLF driver with moon, battery check etc in there.
A warm white XML2

And BAM from ugliest no memory blinky moded, LB ledded flashlight to my most beautiful and useful C8.
Very very pleased with it!

Very nice FmC! So little room to work with in that one, well done and the bling factor is awesome! :slight_smile:

Just swapped emitters in a $4 lantern from Home Depot.

The lantern takes 20mm stars and seems to have good heatsinking, so I used a 4C triple from Kaidomain in one and a Warm White Nichia 219A from Fasttech in another.



Really like the warm white in the lantern.

Now I want to use an extra 1A driver in this that I have flashed with moppydrv…

The stock driver does OK…

Bought some Courui parts off Nitro awhile back, so I took these…. To make this…… For this…… Pretty simple really, just used basic hand tool’s!! Fits tightly together, but I will epoxy it for strength and sealing when everything is done. Got a enough parts for another one when I get bored!! :wink:

Now what are you going to put in it? Buck driver? XHP?

It looks awesome!

I don’t knoooooooooow, yet? Got a couple RMM buck driver’s and plenty of FETDDLDO’s Got some parts for a few XHP35 mods, but I think the first one is going in this thing…. But I can make a couple more extensions for the Courui too? :wink: I have a few extra tubes……

It would be really awesome if you could put a XHP35HI in it. But you need a minimum of 3 cells in serie, preferable 4 cells. With a total of 6 cells thats not easy.
Or use a 4s3p 18350 setup. :smiley:

What cells does that Lantern take?

Got 4 26500’s for the TR20-2 and I could make 2 more tube extensions for the Courui for a total of 12 18650’s 4S3P. Courui would have some extreme run time don’t ya think! But would be really heavy, it would look like my 6D cell Maglite too! :smiley:

WOW,! That extended bare Courui looks amazing.

3 ea of D cells, and it would fit 3 ea 26650 with a little modding…

It comes with the batteries, and supposedly runs 720 hours on low (20 lumen) and 24 hours on high (150 lumen)

Group Buy?
Somebody make this happen!

I got some new Ledil triple optics that are hard to find. The photo below shows the taller Ledil on the left, and the standard 20mm Carlco on the right. Unfortunately, the Ledil is 21.8mm and I cant find anything to fit it. It's just a tad too big. I was hoping that the bezel on the convoy S2+ would fit nicely around the raised dome, but it was not to be. Too bad

I had to do something today, so I sanded off the edges with a dremel so it would fit in the S2+. Below are before and after pictures of the Ledil with the edges sanded off.

With the MTN copper spacer for S2+ and taller optic, the body just screwed into the head, exactly, not a mm to spare. If the dome had fit through the center of the bezel, like it was meant to, it wouldn't have taken up so much room in the head.

Wall shot of the Ledil optic with 3 x XP-G2 S4 2C

Same wall with Carlco optic with 3 x XP-E2 OD

I haven't done much in while with XPG, but the S4 2C seems very yellow to me. More so than the picture represents. I'm not sure if I like it. Is this normal for XP-G2 S2 2C? I've been cranky all day, so maybe I should put it away til tomorrow and look again.

I was wondering if maybe I damaged the emitters and the tint changed. Maybe I'll have to take it apart to check.

PS: this optic might be the solution to mini mags that have a larger head, and the Carlcos have too much side to side play. The dome would probably fit right inside the bezel.

Edit: Yeah, it's pretty green looking. I hate it. It makes my XML 4C look cool white.
