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?

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.

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.

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)

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)

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

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

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

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.

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

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

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:

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

Perfect, thanks guys!

This is… seriously intriguing & inspiring.

I wasn’t going to go with an Emisar… have Fireflies E07 on my horizon. If there’s definitely not going to be one of these TIR boards available for the E07, then I may have to shift gears.

Really nice boards But tbh a lot of this goes over my head!

I disassembled my D4 recently to flash Anduril and found it very tricky to work with given the extremely limited space. I’m not sure I’ll have the skills or patience to take it apart again to add the aux cables. I really like the aux leds in my D4S though so I could be tempted.

The D1 TIR looks interesting as well. Do you have any more info on that?

Any plans to make one for the imminent release of the FW3A?

D1 is not TIR its reflector with aux boards placed inside the gasket

I sanded that board to about 0.1mm thickness

the board with indirect gasket leds is not tested yet

Send me one and i’ll destroy my D1 for science:

LED Light Pipe + Dremel + UV Glue = ???

I know, but why let it go to waste? The D1 doesn’t get that hot anyways I can make some holes, lol

edit; I mean in some cases they help cooling too..

Lexel - I's like to order a couple, maybe more, of these boards. I need one for my ROT66 (early version no AUX LED's), a D4, another quad, possibly an MF01, and possibly when you get the D1 ready. How does this work? pm you?

He will pm you for order details. Payment is through paypal.

Would this install in a D4 far surpass a newbies capacity? Super interested, but it might be a bit much to bite off.
