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

You can put me down for 20 small and 20 large! Thanks!

Excellent.

No probs mate, these things happen :slight_smile: Totally understand. Hope things are going okay with work though.

Work includes job and school, so you can guess which one has been giving me the most trouble these last 3 weeks. :slight_smile:
It’s school obviously. :confused:

Mouser has three 4000k SST-20’s listed as new.

J5402, J4401 and J4402. Are any of these any good?

402 is probably the bin you’d want; closer to BBL. 5402 has higher output.

I haven’t asked Mouser yet.

And besides, you know Texas Ace has a nice source now?

I’ve asked him, and he said that it would be possible to get quite easily from his supplier.

Yes, I have confirmed FD2 tint LED’s from a manufacture I work with. Maukka and djozz both tested them in a SST-20 thread somewhere.

Although there are not that many FD2 bin LED’s available and they could be sold at any time, once gone it is highly unlikely we will find more for some time.

This manufacture has been searching for anything below the BBL for months now and this is the best they have found thus far besides a few FA3 LED’s they got their hands on and are not giving up sadly. They plan to sell them in a light at some point.

Copper is not particularly hazardous. You can look at the MSDS to see associated hazards.

@Hoop, copper is hazardous in the form of a powder, like any metallic powder.

That’s what I was referring to, not copper itself.

I mean, it’s not beryllium levels of toxicity or any nickel salt, but it’s still dangerous, but not toxic.

Also, I would like to wonder why I actually wrote that copper oxide powder is quite reactive. Far from it.
I just meant that copper powder is reactive, like mentioned above.

It’s quite inert actually, and doesn’t react with living tissue at all.

It would be generous and helpful of you if you could hyperlink your more esoteric claims to supportive data on occasion, if it isn’t too much trouble.

In relation to what, metallic powders?

No problem then. It’s just that in my laboratory work at college, our professors asked us to be careful when handling metallic powder, as not only would it be a mess to clean it, but they are flammable since they have extremely high surface area to air, but can also be inhaled, so we should always work under a fume hood.

I’m a toxicologist. This is a reliable reference for the toxicology of copper.

It’s complicated, as Cu is both essential and toxic. As with all things, the dose determines the poison (Paracelsus).

In my view, and as Blue mentioned, just be careful in handling to reduce unnecessary exposure.

I’d like to pitch in for 10 of each type of spring if that’s possible and not too late. If it is too late, no biggie. Thanks.

I’ll avoid snorting rails of copper powder going forward. :+1:

Yeah, snorting L-ascorbic acid powder feels a lot better. Seriously. O:)

Are you still doing the group buy?

TA’s post confuses me, it sounds like the led’s are not available.

Sorry if it was confusing. Basically the LED’s are available but they are not “reserved”. So they can be sold to someone else at any time. Once sold it is unlikely I will find more for some time.

So we should strike quick before they are sold.

Assuming prices similar to before, I’m in for 20 FD2’s.

I would be in for at least 20 FD2’s
