Yeah its very possible that I misread the numbers on the original resistors. Those things are tiny! :slight_smile:

Thanks for the advice on the resistor values. I’ll sit down this evening and give those a try. I really appreciate your help.

So after much experimentation I decided that my orange 0603 LEDs just aren’t going to work in here. Mine are just too inefficient. Just driving them to a reasonable level by themselves passes that 1 mA line. Maybe I can source some better ones, I don’t know. So instead I pulled those back out and dropped some red ones on the board. And it works! I wound up with 1kOhm on the white channel and 165 ohms (2x330 stacked) on the red channel, for a combined tailcap draw of ~710 uA.

Not the best picture but maybe you get the idea:

Thanks again to Neven for all your help. I’ll definitely be ordering more of these parts in the next few days. Hopefully you can get single-emitter mosled boards up and eventually smaller tailcaps for the A6/X6 sized lights as well.

Actually strike what I said above, I’ve already changed it. Too pink for me, on this orange host. Its now a red channel at 230 ohm (330 + 750) and a yellow channel at 200 ohms (330 + 510), with a combined tailcap draw of 940 uA. I like this a lot better, since the red and yellow kinda “blend” to make an nice orange-ish color.

I really like this tailcap. The 4x2 looks great I think (although I really like the 3x2 too) and the LVP option just pushes it over the top. I’ve killed cells in my rarely-used lights with the “normal” lighted tailcaps, completely dead and sent off to recycling. :frowning: No worries with this one, and I love that.

Awesome mod there for the ILC stuff, emarkd!
Wish someday I can order this piece and Neven can do the dual color, too. LOL.
Waiting for the multi voltage version of this new LD4 driver.

Very nice look there! I’m glad it worked out for you!

Oh THIS would be perfect for my MokeGane Sinner 18350! Horrible time to have the checkbook so low… (scrambling)

Just ordered a couple of drivers and a couple of mcpcb’s from the site, looking forward to seeing this in action… will probably have questions :smiley:

Edit: Cool! I like numbers, seem to always be tying numbers to events and such in my mind. I was born in ’62 and here I am posting about my first led4power purchase in thread post #62! AND, today is my parents 66th wedding anniversary. :slight_smile:

FWIW (and to help me remember) I purchased both drivers in LD4-B trim, one set for 12A to go with the Quad board loaded with Nichia 219C emitters for my (next) Emisar D4. The other set to 6A for my MokumeGane Sinner with the Triple board loaded with XP-G2 S2 2B emitters. (or that’s the plan, going in)

Awesome, sounds like some great setups. I ordered 3 more drivers myself, and some of the single-emitter boards. Really looking forward to what you do with the Mokume Sinner. That light is easily one of my favorites anywhere. If it ever needs re-homing…. :slight_smile:

Small parcel has been received, thank you!

Convoy M2、LD-B4(12A)

LED:Nichia 219B V1 R9080 4500K

120uA

Pictures and build quality are both impressive

I'm considering to add customer's product gallery on my web page (also coupons as reward for taking these pictures).

WoW, That’s great.

ILC-1 illuminated tailcap, 120uA

How to change to 80uA?

80uA > this is 40uA per channel, equation from datasheet: Ich=100/Rx, or Rx=100/Ich=100/0.04=2500Ohm, so change both resistors to 2,5kOhm. Be careful with heat close to OMTEN switch (low temp. plastic).

I got my order today, 1 12A and 1 6A driver with a few boards to be able to move the MOSFET up top. I gotta say, these are really pretty and show excellent workmanship. Well, before I worked on one that is. LOL The bits and pieces are like baby fleas, somehow I managed to short both the FET and at least one of the LED’s so I had to figure out what was wrong and sort it out, but in the end I got it running. Then I had to figure out the configuration mode. Took me a bit, cause I’m so dense, but managed it and got it set up just like I want. Poifek!

This went into a solid copper Sinner EDC with an 18350 cell, Nichia 219C’s on the triple MOSLED board. 12A driver. Figured I can turn it down some if need be, and it’s pretty easy to crank it back up if necessary on the fly. Great UI, now I have to memorize it. (yeah, right!)

Makes for a very slick little light, gonna have to carry this one more now. :slight_smile:

Thanks Neven, really appreciate it!

Edit: I set it to 10A in the menu and with a rested Aspire 18350 it does 9.15A at the tail. This works out really well, can easily reduce or increase power as the occasion demands with a few simple clicks. Very nice!

Web shop is a little bit updated,selecting options is now much nicer, also I added few new products and updated prices ;)

Note: since I'm on vacation until next Friday, orders will be processed and shipped after 13th October.

Vacation… :open_mouth: Well then…. have fun Neven! :beer:

Should give me enough time to decide what I need (want :smiley: ) next!

The price is indeed superb. If only the driver was supported by FSM firmware….

Does ILC-1 fit into E2L?

I don't have E2L, but I have Jaxman U1 and tailcap parts are identical to Convoy S2+, so ILC-1 fits (just tried). If E2L also has 18mm washer and 16mm PCB then it would fit.
