Guys, need some advice from you.
Most popular parts (that were known for years and was produced long time before I started), such as S2+ spacers and pills and X6 spacers, their hosts have very limited place inside so parts top have same OD to the MCPCB size.
After Ive tried to solder copper pcb to such plane spacer with solder paste I have realized that pcb goes to the size and it is not very simple to center it.
So, next kits such as X5, M2 (M1) were made with little improvement, hosts have some spare place inside (spacers OD is bigger than MCPCB size), so they were made with rim over pcb plane to center pcb perfectly.
Is there any need in such rim? It makes soldering more easy (Ive seen when smb have soldered parts with bolt inside cental hole ), but if you dont solder parts and use thermal grease you may want to have ideal finished surface, and this is hundred times harder for such lowered shelfs.
So, what would you prefer?
Spacers with pcb centering rim with current surface finish (you can find photos in this thread)
Spacers with plane pcb shelf with better surface finish (#120 sanding belt)
For this moment your suggests will influence on C8 triple spacer design, but I will also consider them for the other parts.
I vote option 1, I am not super picky about the surface finish myself. as the host will still overheat in a min or 2 with or without a perfect finish in the lights I build lol.
Multi-leds:
Cute-3
Cute-4
GT-3 (can fit xp32 too if I not mistaken)
GT-4
Angie (quad that will throw better than Cute-4SS, unfortunately they have different leds disposition)
Khatod also have some 35mm triple tirs, but for my opinion they are more flood than Cute-3M.
In fact this size (35x15mm) is MR11 standart, there are many chinese manufacures that are making tons of them for home spot lights.
As for single leds, you can put any tir that will fit inside if you will use proper spacer.
For example, I have some ledlink ultra narrow beam tirs (35mm od, 20.8mm height). To avoid datasheet misunderstanding, I will leave here actual specifications:
XP-E2: 4° FWHM, 95.4 cd/lm
XP-L HI: 6.0° FWHM, 47.5 cd/lm
XHP35 HI: 6.9° FWHM, 34.4 cd/lm
XHP35 HD: 9.7° FWHM, 18.9 cd/lm
XM-L: 9.0° FWHM, 22.4 cd/lm
Is it in two parts? Looks to have a join at the short end.
My first thought was C8 spacer simply because it’s the most recent new item I have seen being discussed, but when I saw the join I had no idea. And the tapered ends made me think it could be for something that requires a press fit.
Ok, previous photo was not good, it was hard to determine real size, also my phone have big problems with color rendering over this green pad, so most of you confused the material.
