Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022))

I’m in need for a 18650 quad host and was wondering if the Sofirn SF36 would not make a better host than the Convoy M2 since the SF36 with XP-L HD is regularly on sale with a reduction, actually US $16.95.
If not, I will go for the M2 spacer, 3 or 4 units (in aluminum).

One M2 kit (copper spacer) available.
I have build SF36 quad once. But sofirn is not convoy, they used to change flashlight dimensions occasionally. I need to find my drawings and measurement and compare them with hosts that are sold nowadays. Hope some thread subscribers could help with measurements.

90g of copper spacer for a quad S11 build I’m piecing together:

Still have some C8TT heads. For those who are not satisfied with 3 led version, I can mod them to accomodate 40mm anna-6(7) optics:

Now this is tempting but I’m out of my C8 hosts. Hmmm

And yes, I still think that full head design is usefull feauture because you can swap heads.

What would it add the the cost of the C8TT?

$5.

I assume it can’t be re-threaded for the 21700 C8, right?

Right.

What is the total price modded for the 40mm anna optic and rethreaded to fit Convoy M21A threads?

Is the anna optic included or do we need to buy them separately?

No rethread option.
Optics and pcb are available from led4power.com
Set:
Alu head modded for 40mm optics
Brass retaining ring for 17/20mm driver
Cu spacer
Stainless bezel
AR coated glass
O-rings
$31 without shipping.

Do you have any C8 spacers individually? I have a Manta Ray C8.2 which takes Convoy C8 reflectors but also has a head that is almost double the mass.

No. Can try to make one if needed.

If you find a way to retread to 21700 I’m in! I love the one I have already with 3x W6 bin 351D’s and it handles the heat even with a molicel P28A but I’d always be in for M0AR P0WA!

Nope. Rethread is not possible.

Couple of M2 aluminium sets in stock.

Open for single quantities custom requests until August.

Stainless steel bezel for ylp gryphon g180?

Dont have one on hands.
