Thanks for the compliment Steve!

(you always make me feel guilty for not showing as much appreciation for other people’s work as you always do!)

Great light djozz. I got worried when I saw you were using the stock LED board, but then relieved when I saw you jumpered the traces. Every time I kept the stock SRK LED board, and boosted the juice, I kept losing emitters. Yup, the traces kept burning up on me faster than I could repair them.

Awesome mod djozz, it’s always nice to see something that wasn’t designed to be good, being improved massively like this.

Today I modded a Maratac copper AAA with Richard’s 12mm single side FET driver (gruppydriv rev.2 fw) and Nichia 219C.

The driver is currently on sale here: http://budgetlightforum.com/node/46408

Stock LED and driver:

Before vs After, In the photos the 1.6mm thick driver is shown, but I actually ended up using the 0.8mm one. I had to reflow the nichia 219C into the stock mcpcb because the 10mm sinkpad couldn’t clear the reflector base:

Not necessary, but I added a solder blob top and a ring of solder to improve ground contact.

This is the 5000k 70CRI+ version of the 219C, as you would expect the tint is not as nice as the warmer high CRI one but I used this because of the low Vf, it allows it to pull higher amps on a 10440 compared to a XP-G2. According to my ceiling bounce test it makes about 750lm with a fresh efest 10440, on turbo the heat can be felt immediately.

I haven't done a Maratac AAA, but I know that Vinh uses the Sinkpad on them so there's got to be a way.

Great mod djozz! Glad you posted this and great pics!

I’m a junky, I mod lights so I can sell lights so I can buy more light to mod so I can sell lights to buy more lights to mod.

Triple 219bt 45K 90+ CRI w/ CU spacer both from mtn into an S8. I used a med frosted carclo but did not like it. Switched to clear narrow and much much better. Mtn 17DD + 1 w/bistro. L2 brown box clone XHP N4 1C and TR 100 driver. Momentary and Turbo only. Ba#ls to the wall serious only.

I installed an XP-L HI emitter in a thrunite ti, upgraded the wires and repaired the mode switch tab which had broken off by soldering a copper bridge over the outer contacts, works two modes again.

Then an 11mm FET driver & tiny alu heatsink into a thrunite ti xmas edition, pulls around 3.8A on startup. Smile

Finally Nitecore EX11 v2 triple 219c all black with copper heatsink.

A white wall shot at 4 meter distance. The camera was on auto-exposure to show the beam pattern, in reality it is an impressive wall of light:



I think this light is a succes, at least very impressive and I love the tint. I will not likely be doing another mod as expensive as this one, XP-L Hi’s are nice, but there are other very nice leds out there that are 3 times as cheap.


If the light keeps working as it is doing now, it is a candidate for swapping in some future amazing BLF-originating SRK-type driver!

Some nice modding going on here!

I think there's quite a few here that deserve their own threads as well.

My second Bestfire 9-led mod, my first serious high output one, and by far the most expensive mod I have ever done. It is a bit scary to put 50 dollars worth of XP-L Hi's in a light fully risking to blow them all up at some point.

I'm planning a "Poor Man's M43" build, but it's not so "poor" when you start adding up all of the emitters, & then realize that they could all go "pop" money-mouth

I reflowed an XM-L2 5C onto a DTP board and put it into my Kronos X6. The tint is great, and the beam pattern is perfect.

I modded my B158.

I swapped in an XP-L HI 3B reflowed onto a Sinkpad, added 22 gauge wire, a MTN-17DDm driver, lighted tailcap, and bypassed springs.

That was my second reflow ever, and I’m so happy I didn’t mess it up!

I painted the top of the pill a flat black to minimize any artifacts (Thanks pilotdog68 for the paint brand!). Man is it hard to use that stuff without ruining the finish.

I get 5.5-7 amps at the tail from it, and 169600cd. So about 824 meters of throw.

CRX you are seriously busy at the moment, great work!

All I did today was centre the led in two BLF A01…

Does this count as a mod?

It is a Remington Standard, it does not say 12” anywhere but perhaps the 16 means it is a 16” ?
Found it on the street 10 years ago, still works, my son finds it much fun, he is just starting learning to read!

S2+ with a qlite (mtne) + 7 7135s (double) 16mm XHP50 U4 1C 2 keeppower 750s. You can’t keep it on high very long but it sure will give you a laugh. L/MedHigh/TurboHigh. A LOT of light. I am still laughing. Carry some batteries for backup! File, file, and file the driver retaining ring. Everyone should have at least one.

I learned to type on one of those, over 40 years ago. The letters were worn off the keys, still have it as a matter of fact. Now I have to go look to see if it was a Remington or an Underwood….

I’m having a hard time not to write something like: if you show me yours ……….

I found it somewhere eating dust and disassembled and cleaned every last detail of it.
Then I lend it to my kid-brother so he could write his thesis. Got it back a short while ago.
Apparently he could not be bothered to put a cloth over it Facepalm Angry

I tried a 219C on a filed Noctigon in my Olight S2…that was a fail !
Artifacts everywhere in the beam, the TIR does not focus the light properly Sad
So I swapped the stock CW emitter for a nice warm T4-7A and called it a day…

How, and wow, great job as usual Big Smile

No MCPCB at all, it’s just a bare LED with a tiny copper block soldered onto the thermal pad & rigid wires directly to the emitter.
Stuffed a bit of that silicone cube stuff around it too but there’s really not much current to cause much heat. I should have took pics and measured current, but i didn’t LOL

This one was a little more difficult, i accidently dedomed the XR-C while working on it so i’ve covered it with UV setting glass glue for protection.

I’m obviously running out of lights to mod, down to nitecore tubes now… LOL

Well that was stupid.

I just fried a dedomed xpg2 (I hope it was just the LED….). I spent the last few hours modding a UF-1508 aspheric with a dd xpg2 and a 5.5A MTNMAX driver. The 1508 has a bit of an odd pill and a threaded parabolic piece that screws down onto the mcpcb. After several failed attempts at getting the LED leads soldered flat enough I switched over to flat copper sheet. It worked eventually, just a pain to work with such tiny pieces of metal. So I screw down the securing piece to secure the mcpcb and I think to myself “don’t forget to pull this back off before testing”…….. I hook up the driver pop in two cells and a flash of light followed by utter disappointment as I instantly realized my mistake. Facepalm

I put a stacked resistor on an L2 and forgot about reflector clearance when soldering the leads back in, shorted it and fried the driver. I did have Kapton tape on the base of the reflector, but it tore. I’ll be happier with the Bistro driver anyway… Wink Still, was hoping to find out what the stock driver was capable of. Sad

Well I for one am extremely proud of myself. I stacked some chips!
I have never been able to stack chips. I’m a pretty good solderer, but stacking chips has always been disastrous. I have stacked one chip before, but trying to stack a second chip always turned into the ruin of me. Every once in a while I give it a go until I ruin a perfectly good Qlite, and give up.
I have a triple deep red rebel mod coming up, and need between 4A-4.5A, so I got out another driver and managed to stack four 380 7135 chips. Maybe my confidence has improved?
It’s an ugly looking mess, but everything has continuity, and nothing got bridged. It’s that little leg in the center that always gave me grief, so I just cut it off.
I haven’t tested it yet. It should be okay, but I’m afraid if it ends up not working, I’ll break into tears. Tomorrow.
This is it. Please don’t laugh.
