Second Generation Silver Plated High Current Beryllium Copper Springs and 95+CRI SST20!

Thanks!

I just noticed you have LH351D 4k on the list too… put me down for 8 of those too if I’m not already on there…

Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 4,25mm
Spring base diameter: 5,5mm
Spring thickness: 0,8mm
Spring height: 10,50mm
Total number of coils: 5
Plating: Silver electroplating

Same thing for the large spring:

Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 5,0mm
Spring base diameter: 9mm
Spring thickness: 1,0mm
Spring height: 12,00mm
Total number of coils: 4/5
Plating: Silver electroplating

That last one is still problematic. We would lose the mechanical advantage of BeCu C17530 over higher conductivity. Stiffness was an actual advantage there.
Still, removing 1 coil from the large spring is still possible.

Is it to late to add more springs? I should be down for 30/ea already and thought the list was full. If we’re able to still add more LMK and I’ll get you an updated count.

Are we still able to add more springs? I should be down for 30/ea and thought the list was full. If we’re still able to add more LMK and I’ll get an updated total of what I want.

Yes of course. I still have not ordered the springs, so you can just get more if wanted.

Hola pues pensándolo mejor yo también quiero 25 resortes de cada mejor

No problem cris2pu.

Hey Blue bump mine up to 30/30 please… and thanks!

Please update me to 50pcs of both large and small.

Both have been updated.

BlueswordM please put me down for 20pcs of each spring

Got it.

Can I double my order?
20 total now of the large

Thanks

Updated.

It looks like getting to 500 4000k SST 20’s is going to take a while if at all.

If the price of them isn’t too bad I’d be willing to add another ten to my order, maybe others can bump up their orders as well.

I suspect it would be easy if there was more confidence a good flux and tint bin could be secured.

Yeah it’s quite problematic.

A high flux bin is easy to get, but a good tint bin? That’s extremely hard.

Getting a good tint bin requires at least a full reel, or 3 reels for more choice, and 5000pcs to get an actual direct choice from the manufacturer.

So, guys, I’ve started preparing the orders for people with 3500k LEDs and springs since they were the easiest to do.

I will also order the 3000k LEDs soon, which will also be included and shipped with the springs.

The springs will start being made, as specified before, starting at 2/19/2019.

From MTN listing:

"This spring starts out at ~11mm, but after a few compression cycles the spring will remain at ~5mm"

So small spring collapses more than 6mm after several compression cycles? I thought difference is ~1mm.

OK that is pretty extreme.

That’s not what I’ve found for even the small spring…

That’s not what I have.

The large spring has a plastic deformation of about 1mm yes.

The small spring will have more than 1mm, but 6mm is pretty extreme.

The max I’ve had with the small spring is 3mm, at 8mm height.

Perhaps he meant full compression height?

I’ll ask what he meant by it, as it’s literally impossible for it to lose 6mm.
