Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

That is correct, when flashlight is on tailcap switch basically a piece of wire so illuminated taicap can't work. When flashlight is off switch is open, driver can bypass battery + to flashlight tube and illuminated tailcap can work.

Thanks for the aclaration :wink:

light modification of modes is possible ?

for example,

M O D E GROUPS SUB-MENU

1 CANCEL
2 100%
3 35%
4 16% - 100%
5 2,5% - +_35_+ - 100
6 2% - 10% - +_40_+ - 100
7 1,5% - 7% - 18% - 35% - 100%

PM sent.

New product: ILC-0

https://led4power.com/product/ilc-0-illuminated-tailcap-switch-module/

Basically, it is a low cost simplified version of ILC-1, but also fits in any flashlight with 16-17mm switch PCB diameter.

White reflective PCB and switch greatly improve light output and uniformity in this kind of setup.

LVP shutdown is identical to ILC-1, CC part is not as precise or simple to set as in ILC-1(and CC in ILC-1 is very precise - overkill for tailcap anyway), but end result is pretty much identical.

Nice product! I really enjoy my lighted tailcaps and suppose that I’m not alone in that, but I know that soldering all those tiny components is not for everyone. This is a great solution that avoids all soldering!

Btw, great price for such a nice custom build part.

One day I’ll have a set of l4p-powered S2+s

My order arrived fast and perfectly seall. Very good customer attention. This is by far the best flashlights drivers in 17mm and more important with a lot of unique features and PWM LESS.

Btw this new ones iluminated tailcaps ILC-0 , looks very nice and at good price :+1:

I received an order today, packaging was good and shipping was relatively fast (less than 2 weeks to Italy).
I have a question about driver behaviour when using illuminated tailcap: if the driver shuts down while the switch is keeping the circuit closed because of lvp, will the drain be limited to the driver standby drain or will it pull the 1mA bleeding current too?

When driver is ON (tailcap switch is ON)and shuts down because of LVP (2.8V),it would drain ~1mA because of bleeding.Of course it would be not a good idea to leave driver/switch turned on when this happens, but since LD-x4 is clicky driver,turning flashlight/driver off after LVP is intuitive/normal thing to do.

Also this is the case where ILC-0/ILC-1 LVP shutdown becomes very important: ILC-0/ILC-1 has ~3.0V LVP shutdown level,below this voltage it draws ~1uA of current, so battery is safe from over-discharge.

Without LVP,illuminated tailcap would constantly draw current below safe level (especially red,orange,green) which would lead to destruction of battery.

Thanks for the quick answer. I agree it isn’t really a problem, this was mostly a curiosity I had. Also the LVP feature of your tailcap is great indeed, I think I’m going to order a couple of ILC-0s in the near future.

This is great! Beautiful product. Any concerns with high current through that switch? Should it perform as well as the reliable Omten in high powered lights?

This is OMTEN switch.

Correct, it's Omten 1288.

It’s too high to fit into E2L.

I just tried it in my E2L host (haven’t assembled the light yet because I’m waiting for other parts) and it does fit, though the retaining ring sits a bit too high (something easily solved by sanding it a bit). Perhaps you left the washer in? I think you are supposed to remove it when using ILC-1.

yes, I removed the original washer. But could not screw retaining ring. To be honest I tried only once. Probably ILC-0 would be a better solution for E2L.

On Convoy lights, because original switch PCB diameter is ~16.5mm and ILC-1 is 18mm, "effective" height of ILC-1 is ~1-1.5mm higher, but it still fits without problem.

ILC-0 has 16.5mm diameter so it would fit like original switch PCB.

Hi, any plans of make 20mm version of this “L4P 4040 DTP 16mm for Luxeon V” ?

Also, any plans of make XP version of the dtp copper board (with 0402 NTC footprint on board)?

Thanks :wink:

Last 4 lights I worked on had 14mm emitter MCPCB.
no one has ever made a 14mm DTP XP. And the 14mm XM Tpad are getting really hard to find.
I have to request these. I would buy 20 of each to start.

I could start a feeler thread if you would like to test interest.
