[1900k edition is in!] WTS: 1900k-5800k 5mm LED 95+ CRI

Alright, I will sell these as 5000k.

These will be priced at $7.62/pack of 50 ($8.00 after fees).

There are 19 packs of these available. I have no plan of restocking these.

PP sent for 5000k tracked.
Love them all and hate you also cause now i’m buying 5mm hosts like crazy

Cheers

^lol

But hey, the good thing is that 3xAAA lights are wide enough for 21700 cells. :slight_smile:
With some wizardry it is often quite possible to get all 70 millimeters in there too.
But sub C NiMH cells now have become interesting too.

Gives you enough space for a boost driver (which you’ll need).

Hmm…
Still a good CCT for headlamp work though.

Hey, that’s us ! :smiley:

Will normal users buy these LEDs? :wink:

Any way to tell / guess what causes the difference?

Ah, Throwers ! :blush:
Not what i personally hoped for, but should do a decent distance with a bunch of them (> 20 LEDs) together.

I guess you could dedome these to get less (or no) throw.

Looking forward to your output test (which i’m sure you will do soon).

The output is similar to the others at least, was not planning a test these days, maybe later.

Shipped:

LowLumens: (1x 2300k / 1x 3400k)
Tldd: (1x 2300k)
id30209: (1x 5000k)
LedTed: (1x 5800k)


Well, after the recent bunch of lost mails so it’s time for to set up a ground rules of how much I can comfortably compensate for the loss. I have modified the shipping table so it includes the information on how the compensation will be made should the package is lost. The rule will be in effect from today onwards (Jan 21, 2020).

This does not apply to those who paid before that, which they are in for 1 additional shipping attempt if I know convincingly that the package is lost.

That sounds good^^^

Thx!

New host for 5000K arrived

Came here to confirm receipt of my latest LEDs and…

Ooh, 5000K LEDs! Paypal sent :slight_smile:

I warmly recommend buying from rngwn, he packs his stuff well and ships it quickly. Both of my packages came from Thailand to Scotland in 10 days flat, with all LEDs in perfect condition.

Thanks very much for making these rare LEDs available to us, rngwn :+1:

You also have Royal Mail’s (relatively) efficient handling of mails to thank for that.

Just checking in to say I received my shipment on Jan 31, About 10 days to reach California.

My first time trying the 2300K, I am so glad I finally ordered these!!! Perfect extra warm color temp for candelabra, night lights, etc. and preserving your melatonin levels at night.

Thanks so much for offering these little gems!

I got my LEDs today and played with them as soon as I could rig up an ATtiny85 project.

The: LEDs, shipping, packaging, and service were all top notch.

The price for quality of special binned emitters is unbelievably affordable.

I see some LED strips with 5mm LEDs. Would be a nice swap target. :slight_smile:

You always find the weirdest stuff, Argo. :+1:

(yes i’m back from France again)

Alright,

As per postal service’s announcement regarding Coronavirus, I will only be able to ship to Mongolia (if somebody happens to live there) using Express service until further notice.

Mongolia goes high CRI!

But that is quite a bummer, I hope for your undertaking that the virus will be under control soon.

Shoot. I worded that poorly once again.

Shipping to other countries (except China and Mongolia) are still fine as of now.

I obviously can’t (and probably won’t) ship to Mainland China and Hong Kong. Taiwan is still fine.

Regular (Ordinary/Tracked) shipping is unavailable for Mongolia.

Ah! :+1:

Just received my order,and I am now using one of the 2300K LEDs in my 30 year old Mini Maglight incan. The tint is fantastic.

Thank you very much rngwn, what a great find these LEDs are!

I promised rngwn several weeks ago I would do a destructive test on some of these LED’s. I’ve been very delayed due to life being busy. However, I did this week finally have time to load ceilingbounce on my wife’s old smartphone and do one test on a 2300K sample.

It ran at 150mA for several hours before I had to stop the test because I couldn’t monitor my sketchy setup any more for safety’s sake. When I let it cool down and restart, it was still nearly as bright as at the start of the test. I was surprised it survived longer than 30 minutes!

I think the test is unrealistic, however, because at only 1/2W, even the legs provide significant air cooling. To better replicate a flashlight, I plan to repeat the test with the legs trimmed short, and the LED facing vertically so convection is more limited. Depending whether it dies quickly 150mA, or shows no signs of dying in a reasonable test duration, I will repeat it on another sample at higher or lower current.

Hopefully I will have results this weekend. These are really nice low power LED’s for tinkering with, so I think it is good for the community to have reasonably accurate information about how far they can be pushed.

I think I misunderstood the answer to a previous question about this.

Is that PCB the guts of one of the Ikea lights? If you swap in an rngwn LED, does it still flicker?

The tea lights my wife has do not have any dedicated controller. The 5mm LED itself has some sort of internal flicker control. If I replace the LED, the tea light no longer flickers.

I want to replace the monochrome amber LED’s, but not lose the flicker effect.
