Sorry for the delay. My cross country season has just ended so I’ll be able to visit the machinist during the week.

Do we have a consensus on which pill/design to make?

HD2010 by far.  There are more votes for C8 pills, but most of them aren't willing to pay realistic prices.

The low mode should be lower.

Great, we’ll stick with the HD2010 for the first round then.

I really like MRsDNF’s pill design, keeping the walls as thick as possible.

There seems to be a lot of room for improvement, especially inside the driver compartment and the pill-to-body threads.

Oh and my apologies, I realized that the HD2010 pill in my photo wasn’t the real one, it was a C8 clone. Fixed. Smile

I guess I would only really be interested in a copper HD2010 pill if it offered the option of mounting something like a resistor moddable ~20mm driver for a 2s stretch mod. Something like MRsDNF’s stretched hd2010 that could actually sustain >6A current for a while would properly justify a copper pill for me. If it’s just a more massive copper version of the stock pill that only fits 17mm drivers I don’t really see the point.

MRsDNF’s design looks great and it doesn’t seem like it would be hard to include a copper/brass adapter ring from there that would also fit a 17mm driver.
Is there a preferred/standard ~20mm 2s buck driver that would fit the bill as a generic alternative to the 17mm driver?

In any case thanks for offering this and I may get more enthusiastic as I see the final design develop Smile
Cheers

Um, who is offering the next round of copper pills?

MRsDNF’s design rocks! The thicker walls add more mass in an almost hidden area, with a doubling of the thickness at the shelf, as a minimum, I’d think it would give substantial improvements especially when running up towards 5A and beyond.

That one has my vote!

I just got the F13, seems like a modders dream light! Very easy to work on, plenty of elbow room to make improvements and yeah, it’s already got a 20ga Silicone wire upgrade and an XM-L2 T6. (I’ve had it a little over an hour) Now, How do I get rid of those crazy blinkies and next mode memory! :Sp

Atm for those who are willing to go above $20:
C8 = 10
P60 = 8
HD2010 = 7

People keep disregarding the P60 because of its un-optimal thermal design, but it’s BECAUSE of it’s design that the P60 is in need of the copper most!
In copper pill forum threads, it feels like I’m the only guy with a SolarForce L2P who needs the copper badly…

Again, contact mattaus if you need a p-60 copper pill badly. I know he has some in hand and is probably going to be making more.

I made my own when they were hard to find. Nothing fancy, just a big chunk of copper with an inset for the driver and the noctigon re-flowed on top.

I see. I will ask him. Thanks.

Edit: I just PMed him. But I only recall him selling optic-type pills in his threads, and not the standard reflector ones which I want for throw…

A benefit of the thick walls is that you can bore it out to fit a 20mm driver. 

The low mode should be lower.

With as quickly as the copper pills for the HD2010 sold out, I bet there's a lot more that haven't filled out this survey.  And that was paying $23-26 iirc.  Plus there's a good upgraded pill design courtesy of MRsDNF that only needs a minor change before going to production.

The low mode should be lower.

I’ll be heading out to the machine shop in an hour or two, and I’ll ask about the pricing of the “enhanced” HD2010 pills with more copper between the walls and in the driver compartment.

I’ll ask about the Convoy C8 pill as well. Seems like it can have more copper in the driver compartment, unless you’re doing some crazy AMC7135 stacking.

Any questions comments or concerns you want me to relay the machinist?

Thanks!

I missed out on the input stage, but I was wondering about the possibility of a small mini-C8 pill (Copper or aluminum).

Possibly if there’s more demand. I’ll have to get that light as well. Smile

I’ll also try to widen the diameter of the PCB contact plate so that it can accommodate 20mm SinkPads/Noctigons as well.

Currently, it’s a tad bit small:

I would be one of those people who are interested in a hd2010 but haven’t filled out the survey.

Will be watching for updates

Hey guys, I’m back from the machine shop with samples.

OP updated with lots of photos. :bigsmile:

Any questions or comments, please post below.
Please let me know if I’m headed in the right path (or not). Smile

Fantastic looking pills Ryan. For that price I would not even think of making them. Go for it guys.

There’s a lot of copper above the driver, so if you’re stacking AMC7135 chips, it may not fit.

How deep is the driver cavity exactly? I would say stacking chips is what this pill is made for so it would need to have enough clearance for at least an extra layer of 7135s and ideally enough for 2 high on top of the stock chips.

A single layer of extra chips will only get us to 4.5A so you’d need two extra layers to get to the theoretical maximum of about 6A.
So that would be my suggestion, make the driver cavity deep enough to accommodate a double stacked driver and it should cover most situations.
Still plenty of copper left above in any case.

For $20 I’ll probably be in for one too, they look very solid Smile
Cheers

In the sample HD2010 pill, there’s 3mm of clearance for components above the driver PCB.

If you stack one more layer of chips, I think they’ll touch the pill, but you’ll still be able to press fit them. (Plus, the chips are then heatsinked.)

If there’s more demand, I’ll increase the clearance to 4-5mm.

Thanks for organizing this, in for 2 of each copper pills for HD2010 + convoy C8.

Prefer little more cleareance for stacking more chips on the hd2010 pill but ill buy them either way.

I’m in for one HD2010 copper pill, looks great! Plenty beefy and I usually only stack on the spring side of the board anyway, but sometimes add to both sides. Still, if there’s not quite enough room I can always shave it a bit.

Thank you very much for doing this Ryan, really appreciate it and look forward to getting my HD2010 up to it’s max potential…finally! Smile

Very Very Nice!

Hey Ryan, the angle for the drilled holes can be a bit tricky, I wouldn’t mind there being a plunge cut to get the clearance to the outside edge, this would facilitate both a 20mm and a 16mm star.

Just don’t want that cross cut taking contact out from under the emitter.

So straight holes through would be fine with me. Even without the plunge cut, I know I’d rather have to do that myself with a dremel tool than have it rough or misaligned.

No problem, got your response as well.

It’s been challenging to design the ideal pill, but it’s also been really fun. Thank goodness today was a no-school day.

The reason I thought of a diagonal cut was because the plunge cut from the 16mm hole to the 20mm hole leaves an air gap between the SinkPad and the pill. Although probably negligible in terms of lumens drop, I thought making a diagonal cut offered less thermal resistance.

If there’s enough demand for this (5+) I’ll do the straight vertical holes for those who want them. Smile

Apologies for the n00b question, yet are these sold bare, or pre-assembled to folks desires/requirements ?

Also, what’s stopping machining these with the pad directly integrated into the pill, rather than a separate item that has to be added ?

These are sold as bare pills, so you can mix and match LED’s and drivers to your own liking.

Machining pads directly is a challenging task because one needs to manage the wires onto the LED, but Old_Lumens specializes in this field. Smile
