This is regular 18mm rings that can fit convoy S series.

ok, thanks for the aclaration.
Look a bit tall, so i don´t know if will work good. In the images looks like at least 2x tall of the regular ring but I may be wrong.

Do you have any info for that?

Inner hole is 16mm.
As you can understand there is not enough place to make holes (similar to the stock ring) for unscrewing, so they are changed with milled cuts.
Also, stock ring height is not enough for such cuts, thats why custom rings are taller.
Ring height is 3mm.
Ring OD is less than 18mm. So it can easily enter any 18650 battery tube.
The only issue (contacting cell outer heatshrink/isolator) may be met if you dont use positive (driver) spring.

Hi,
great explanation, i undertand you. So, if i undertand correct there is no problem at all because the driver ring don´t touch with the 18650 tube, so the flahslight screw in normally.

Time for some gift coupons:

first two BLF members who correctly answer to question: how many LEDs and which size there are on ILC-0, will receive 6€ led4power store coupon valid for ILC-0 or ILC-1 purchase (valid for 14days).

Generous! I think I know that, but since I can make my own illuminated tailboards I want someone else to win this :slight_smile:

4 leds,
size 0603
:beer:

smaller I think

1—- 4 leds
2—- size 0603 :wink:

Ok, that was easy,next time questions will be a little bit harder:)

Correct answer is 4 LEDs, 0603 size, so Sirius9 and alberto7 won 6€ coupon for Illuminated switches product category - congrats!

Please register on led4power.com if you don't have account, and send me your usermane/mail on PM.

I already send the PM

Thank you for doing this :slight_smile:

Thanks led4power, this are realy next level lighted switches :smiley:

led4power, I have ILC-1 and Convoy S2+. However it does not fit into tailcap. There is no thread left for a retaining ring:

Other side:

Transparent washer is just for protection during transport! ILC-1 should be installed without any washer.

That explains a lot. Thanks :slight_smile:

led4power, sorry to bother you again. I’ve noticed some annoying oscillation in brightness. It is visible only in 1.5% and 2% modes (checked for 7A and 9A configuration, with and without moonlight enabled). Measurements with multi meter shows oscillation between 135.3 and 136.4 mA (for 7A). Is my driver defective? Can I fix it somehow?

"Oscillation" between 135.3 and 136.4mA is pretty normal because it comes from thermal noise superimposed on useful signal(we're talking about 1-2uV of noise), the real question is how you can see 1mA fluctuation at 135mA current? Anyway,one way to reduce it is to increase signal level from shunt at a cost of increased driver internal resistance.LD-2 to LD-4 drivers have very low internal resistance because at that time there was demand for driver with DD-like resistance on high mode,which was because of high Vf snd generation CREE LEDs. It's possible to reduce that effect by 10times with shunt and one 0402 resistor change,at a cost of increasing driver's internal resistance from ~5mOhm to 14mOhm (still pretty low, difference would be noticeable only if you drive 2nd generation of CREEs close to max. current).

I’m using the driver with triple nichia D240. Those measurements (around 135mA) was taken with cheap multi meter (not high resolution oscilloscope), so maybe fluctuations are bigger and that’s why they’re visible. Anyway - I can live with that :wink:

Hmm, <1%, imho nice result.

Idea: switch that would glow blue when in off position and red when flashlight is turned on (or any other color combination) :smiley:
