Correct, it's Omten 1288.

It’s too high to 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.

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.

It is still quite a financial risk having ledboards made, the MRQ is usually in the hundreds so you must have reasonable confidence that you get that many sold. I have no idea what the size is of l4p’s flashlight undertaking (not huge I guess) but I’m already (pleasantly) surprised that he had a 16mm 4040 board made.

Speaking of 16mm 4040 DTP, they are out of stock now; I have plans for 20mm version and few other pcbs, but as djozz said, start cost is high and you don't know how well they will sell.

Hi, there is any option for use the Luxeon V with the ld-a4 driver in convoy s3 host?

for example the vf of the Luxeon V at 6A is aprox 3,35v so… (4,2-3,35) *6 = 5,1w.
So, its out of the maximun that driver can support (acording to datasheet).

i see the aluminium piece for the s2+ but i don´t like that the s2+ has pill and a very wide retaining ring (that would be problematic with this driver).

So.. any options for built a luxeon V flashlight with this driver in safe limits?
Put a cube will be enought?

I think that runing DD will works (not driver heat) but thats probably produce 8-9 amps and thats too much heat for the small host.. so its desirable to limit to 6 or lower amps in my opinion.

Thanks Wink

Finally finished (no tailcap mod yet): Jaxman E2L + LD-B4 + Nichia 219C sm503. More details here.

Thanks. So I’m thinking about NOCTIGON 3XP MCPCB & Nichia NVSW219CT R8000 D260 + LD-A4 + ILC-1 + E2L.

What do you think? Will it be good match? What amp version should I choose? 6A for 3 LEDs = ~600lm per LED. 12A for 3 LEDs = ~1000lm per LED (I’d prefer 12A because I could configure it at 8A and it seems to be ideal). Is LD-A4 enough or should I consider B-version?

I have thin retaining rings compatible with S2/S2+ etc.

Best solution would be thermal kit similar to S2+ thermal kit,or at least approximation.

Silicone cubes may work if you don't bypass springs and use 10Amp discharge batteries.

Very nice to see that Wink I will buy 2 pieces for use with LD-A4 thermal enhancement kit for Convoy S2+ and the Luxeon V.
Do you have any picture?
The rings is equal but less wide?

Yes, thermal kit would be the best, thats for sure. If the thin retaining of kiriba-ru works well i will go for the s2+ with the thermal kit.

BTW thermal adhesive (artic alumina) works for glue the aluminum to pill ? or this change the measures?

Thermal sheets are not adhesive, their purpose is to fill small air gaps between contact surfaces.

Total thickness is such that everything fits tightly into host for best thermal transfer.

yes, i see the images. I think that the images was of other diametter.

Its the same ring as the s2+?

I understand you. I think that i formulated the wrong question Facepalm

My question is if i can use thermal adhesive (Arctic Alumina™ Thermal Adhesive) instead of the sheet?

hahaha my english It’s not too good

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.

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