This looks so nice. I have been interested in this for my D4 for some time now. I see in the first post how to order (I think), but I would like to ask a couple questions.

1. Where can I see video/pictures of all the colors?
2. Does this board just mount on top of my existing D4 MCPCB and pick up power from the traces somehow, or is there wiring involved?
3. Do I just PM you an order, and you send me a paypal invoice, or something else?

thanks, Matt

1. its hard to get proper pictures from a digicam
here a picture from testing out the brightness to calculate the resistors, for my eye all colors were evenly bright

from left to right
blue, pink, red, orange, yellow, green1, green2, Ice blue, WW, CW

the one green1 is very inefficient(even worse than yellow) at the currents we use it
the more purplish changed with last batches to more magenta pink, seems they changed the phosphor

2. for the D4 you need at least to connect it to battery + and - so at lerast one wire needs to go to the driver
so best is to flash D4S firmware and use the pad for the Aux LED output its there on all D4 lights but was unused

3. yes PM me for order

32

How challenging is it to get the board in the right placement and get the wires soldered back to the main LED board and to the add-on board, and put the optic back in, all without shorting or twisting anything?

33

depends on the light
D4 is the driver often tight
D4S, ROT66 just swap
MF01 needs wires from driver

Hi lelex, have you published the schematic for your lighted TIR boards?

I’ve designed a TIR light board for a one-off project of mine using all passive components and a comparator but I’d be interested to see how a “smarter” solution was designed and laid out.

35

I am using pretty much same as you a comparator and LDO generating a reference voltage
I basically drew on some paper a scematic which is lost generally starting a new design on an already functioning board and keeping all nets as they were

on newest boards like E07 I have added a fet to get the comparator working down to 3V battery voltage so that MCU diode drop is not increasing the lowest voltage
even the parasitic drain of LDO and comparator is very low

36

I am build my own gfs16 pcbs and you can see how loneoceans made his led board. I do not see the schematic there yet but it looks like it use two nanopower comparator and one voltage reference to have 5.5uA super low standby current. I think because no LDO is used, the standby current is much lower.

The two bank of leds are switch on and off by small mosfet with battery indicator. I have order the pcb and parts to make my own led board also. With board file and part list, not too difficult to trace out layout to generate schematic.

37

he uses a Maxim with integrated reference that has a parasitic drain 2-3 times more than my solution
I asked him if I can use his board as a starting point to do my own, but I ended up making some things differently including another comparator(mainly because its cheaper and lower standby drain)

38

it look like that is the older version when I order part. The rev B use only one voltage reference and two comparator I see for 5.5uA standby current (from page)

39

How does that work? TIR board positive direct from LED+ and the ground from the FET drain? FET gate controlled by the MCU aux LED output?

Hello Mr. Lexel,

I am trying to add some side light to my flashlight. You seem to have a lot of pretty color led. Can you please share us the part number for the led colors you are using?

green
blue
ice blue
pink
WW
red
CW
orange
yellow
emerald green
purple

Thank you Mr. Lexel!

EDIT - sorry for asking question, I found answer on aliexpress!

Thank you

I order from this Aliexpress shop
https://de.aliexpress.com/store/1758868?spm=a2g0x.10010108.0.0.456e161fGJcOHi
but you can not except same efficiency or colors over different orders they seem to change

red and green latest batch were less efficient and Pink color changed less purple but more efficient

42

Will this board with only red aux on full power produce enough light tu use it as a usable moon mode?

43

Not with a reasonable standby current

44

I finally got my board installed in my D4. I like it!! Not easy to install, but not that much harder than flashing my D4 with Anduril.

45

Does the D4 board fit any 20mm quad mcpcb or does it somehow only fit the D4?

46

Yes!
I used LED4Power Quad DTP Board

I should fit all 20mm quad boards which are quad TIR compatible, as this ensures the same hole spacing

47

I dont think it makes a difference that it’s a D4 but the tolerances for where the LED +/- are may not work for anything but a Noctigon 4XP. I guess YMMV. Maybe Lexel has tested others.

Edit: I see it works on L4P board. Looks less likely to work here:

48

true. That I did not think of! Sorry for my misleading post.

49

Perfect, thanks guys!
