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

You’re welcome, but how did you bust a single LED?

I’d like to know. :slight_smile:

Please add 12 3000k SST-20’s to my list.

Thanks

I do not have the proper equipment for reflowing electronics, and so I was using the stove set to a low setting. I usually have no trouble doing single led boards, but multiple led boards give me more trouble. That combined with being a bit impatient while trying to clean excess solder from around the LEDs, and I just clipped the corner off one…

Getting a hot air gun or a regulated hotplate is on my long term wishlist…

Well, at least, if you want a triple SST-20 3000k build, you know where to look.

I actually have one triple 20mm MCPCB left, so I can build a triple LED array with my hotplate setup pretty easily.

Do you like your hotplate setup? What is it? I seriously need to figure something out sometime in the future…

I really like the jaxman e2l as a host, and it requires very delicately reducing a 20mm triple board down to about 18mm without shorting the + or - to ground. Its a pain but I enjoy the end product. (and mostly enjoy doing the work too)

Ohh, I did end up ordering the one Unloco linked: https://www.aliexpress.com/item/UYUE-946-1010-LED. It's the best price on Ali for this model. Talked to my EE friend at work and he thought it was a good deal as well. Thanks everyone!

Yep.

Hotplates are a godsend, especially if you have a stencil.

For components that have low thermal mass, it makes it so easy to just reflow, slowly raise the heat, and the part is soldered down.

For high thermal mass parts, like springs on tailcaps/drivers, or parts very sensitive to heat, using a hotplate can be very useful to preheat the part and solder it using a soldering iron.

Heck, to make my job even easier, I use SnBi solder paste, since its very low melting point is perfect for stuff that should never get close to 100C, like springs and low power builds, making the job that much faster too.

Also, is there someone who would like a triple 3000k/3500k build on an MCPCB? I have one left that I can use for this.

Could you add me to the list for 15 of both the small & large springs? Thanks!

No problem.

Added to the list.

Just used 4 of the small springs on a mod of the infamous "TESLACOM" flashlight. There was a 1/2 price deal on Amazon for it. First I thought it was a junker, umoddable, cheaply made, but ended up getting it apart and could see a couple things about it could be fixed up, one of which is better springs.

This is it, but I only paid $18: https://www.amazon.com TESLACOM. Beleive me it's not worth $37, not even sure if it's worth $18.

God this light looks bad.

It could be so good too.

N4 SST-40 5000k, BeCu springs, 5A buck driver, nice good fins, a good 5 mode UI with moonlight but that would cost a large part of the profit margin.

So, I’m going to start sending PMs by Tuesday to the people in the final list:

So, if anybody wants to get on the list for the springs and 3000k LEDs, now is the time.

Please add to my order 6 x 3000k leds.
I am in line 43.

No problem:

Will start sending PMs now.

Hey blue, did you change your paypal email for payments? Just checking to be sure?

No, I didn’t.

Why?

My mistake. :person_facepalming:
I went through my paypal payments and found the same one you just PM’d. :+1:

Hi Blue,
Is there still time to count me in for:
12x SST-20 4000k
12x 351D 4000k

PayPal sent. Thanks for organizing this. I look forward to checking out these springs in person.

@bhstinger, you can still enter for the SST-20 4000k and LH351D 4000k.

Just need to find a good source of them with great tints…

I still haven’t found anything with a confirmed tint bin.
