What did you mod today?

I have not measured it before closing the light but I think that I remember checking it before and that these leds are closer together than a triple Noctigon/Carclo triple optics.

Just considered this with an Osram IR diode, Nichia UV LED modifying footprint and a Nichia 219C

using a TA triple driver with modified mode groups and a low drain battery

FET channel goes to the Nichia 219C, springs not bypassed and thin wires to add resistance
second AMC stacked over the single 7135 to the Nichia UV LED
4 AMCs to the 5.8W Osram Ir diode giving 2W 850nm

having as output channels
white only
white plus IR 50% PWM
IR only
UV only
UV plus IR 50% PWM

That does sounds pretty cool, paired with a matching tailring would really make a plain black light look more refined. Most lights have fairly shallow cutouts and rounded ends to those cutouts so getting the complex shape right so they fit in perfect might be tricky. I’ll look into it with either that copper composite or wood. Been working a lot with wood lately since we just launched the Eye of Sekhmet line.

About the dedomed xp-l2 option , is that xp-l2 sliced or fully dedomed ?

I would appreciate a pic :slight_smile:

They are sliced and diced, the dicing improves the performance by about 12% and in the end they end up a only a little below a really good dedomed XP-L in throw but keep a really good lumen output and are more stable due to the silicone still being intact to protect the phosphor. They are a nice balance of throw and lumen output, not really made for max throw like the high throw version which does 260kcd.

I made a p60 drop-in out of a copper rod and pipe bits. I used a Nichia 144a led, djozz’s mcpcb, H1-A boost driver, and a shorter smooth reflector to fit the whole assembly. I soldered the mcpcb onto the drop-in shelf for better heat sinking as well. Then I put it in a SF P1D I had laying around w/ a orange tritium in the tail and pflexpro’s MT lens. I still have to bypass the spring on the driver side and polish up the copper but the drop-in is working fine. I still need to figure out how to make the driver always start on the lowest setting, since it seems to have next mode memory.

Cool, is that the boost driver from Kaidomain for MT-G2’s etc?
Next mode memory?

Yes, I got the driver from Kaidomain. Whenever you turn on the light, it’ll go to the next mode that you last turned off the light on. The driver has ll-l-m-h and then double click for strobe. So if you turned off the light on medium, it’ll start on high when you turn the light back on.

Aw man, you’ve taken away my happiness but thanks :slight_smile: , I was planning a build with that driver. Cancelled, unless it’s just a capacitor mod or the like.

Yeah, that’s the only disappointment about the driver but on the positive side it puts outs good power. I got around 5 amp reading from the light.

Gonna have to think about that or find a fix if there is one.
NMM reminds me of some of the very first cheap lights I bought (shudder)

Yeah, same here. I still have 2 more coming my way which I ordered before knowing about the NMM. I’m hoping that someone comes up with a fix for it as I don’t have the expertise to do so.

Some NMM drivers in the past could be fixed to no memory with a pencil stripe over a capacitor. Who knows.


I change the xm-l2 in ec4 to xhp50.2
But, too bad, it doesnt work properly, sometime it can go high mode, or doesnt work, or very low output

With 2 cell and constant current drivr, i hope it works, but disappointed, now i have to order xm-l2 led

XHP50.2 is a 6/12V LED
XM-L2 is a 3V LED

the old XML2 should be fine

I know, but i measure the Voltage when open circuit, it’s almost same as Vcc(about 7. Volt), so i guess it will adjust the volt so that current is stable

I have EC4 with XHP70 and stock driver and it works well. You need to use thermal resistor.

I lost the thermal res when reflow the led(damm, that little thing), i dont know the value, so i just solder 10k resistor

So, i reflow the xpl-hi led, change mcpcb to cooper, now it works, so i guess my driver wont work with xhp50 led
I’m sad:(

This is bad news, I want to swap to XHP50.2 too in my EC4…
