Nichia 119's for cheap (also Cree XLAMP-7090's)

got mine yesterday, thanks tp :slight_smile:

Please put me down for 30 please. Not sure what I will do with them yet but I still have a few Xitanium drivers lying around in my box (outputs 700ma.) I just bought a house so Iā€™m sure Iā€™ll be able to scrap up some fixed lighting things.

Thanks!

Mine arrived today. :bigsmile:

Hi,

I finally got around to trying this, reflowing 3 of the Nichia 119s onto a parallel 3up board from IS.

I used the Kapton tape method to insulate the middle pad:

and it lights up!

I just tried to solder some of theseā€¦
I used regular solder, worked not so good firstā€¦then I pretined the LEDs too and that worked.
They look definitely not so neat like yours, they didnā€™t jump in place when hotā€¦next time I will use standard reflowing procedure with solder pasteā€¦

On the single led I used the grinding and filled the gap with Fujik, but Fujik behaves a bit weird while soldering. The kapton variant works better.
The one with the small copper piece and blob of Fujik is a test, I first used just the wires as heatsink(50mm awg22 on each side) but decided to spend a copper scrapā€¦

The light is interesting because colours look really good but the colour temperature is neutral never seen that beforeā€¦

Hi,

Yes, at least from my one attempt, I think using solder paste and kapton tape to insulate the middle pad on the board seems to work well. With that, the emitters did ā€œmoveā€ into place once the solder paste went shiny, just like normal reflowing.

I was pleasantly surprisedā€¦ I was worried that the kapton tape would cause a problem with the reflowing and moving because it does have some ā€œheightā€, but it worked fine.

At least from my experience, Fujik melts when it gets hot. I had tried to use Fujik to hold a 7135 in place when I stacked it, but that was a disaster, because the Fujik went liquid, and the 7135 just started floating around :)ā€¦ Same thing happened when I tried using AA instead.

Hi there!

Just wondering if you still had these available.

Iā€™m now pretty sure that I threw out my 30 emitters :_( (maybe this will teach me to look in those small open packets before recycling them)

If your answer is yes then Iā€™d like 20 30 more emitters please (thereā€™s a project I still need them for.)

thanks!

Edit - actually 30 again please.

Yes, I have more. I also have a few with a 3600K color temperature.

I will take all neutral 119ā€™s please.

Thanks!

Received mine yesterday, wish I would of went with a few of the warm ones.

Iā€™ll probably order another 10 and get 5 of each this time.

I got my Nichia 119ā€™s and tested one so far. Looking to use them in a project soon. Thanks!

Still available ?
International shipping?

I just got some about a week ago. Heā€™s probably still got some. As for shipping:

if these are still available iā€™m interested in 20 of them. ( sent you a note)

Request: has anyone have a few (3or4) of these 119ā€™s spare for me to test a ledboard for 119 leds? I will pay for them plus the costs of mailing them to me in a plain envelope.

Thanks!

(I canā€™t find Nichia 119ā€™s anywhere for sale nowadays.)

djozz, if texaspyro doesnā€™t answer, Iā€™d be happy to send you a few of those that Iā€™ve got. Send me a pm if you donā€™t hear from him soon. Also, if anybody is interested, a quick search on eBay just now brought up this listing for Nichia NCSL119T H1 3000k LEDs

Hi David, I did not think of Ebay, thanks for the link, the seller is even in the Netherlands, I will order 4. :slight_smile:

Glad I could help. :wink:

Sorry for the bump,

but where can one still get Nichia 119 LEDs (cool white)? On their website there are specs for NVSW119C, D and F (lat two labelled ā€˜new productā€™), but no distributor has any stock, and all they tell us is we have to order 3000 pc. from Japan, lead time 6 weeks.

We are supposed to solder 35 boards (9 LEDs each) next week, with only 240 LEDs on stock, and no time to convert the layout to the 219 (which is on stock everywhere). Now I am the one to blame for choosing the wrong LED back in 2014. Could I smell that everybody would go for the 3-pad footprint? Anybody have some 119 left over? Eng. samples welcome. 119A, B, C etc. is no problem, we can adjust the current.
