I thought I’d read somewhere here that they weren’t going to be manufactured.

DBcustom had spoken to a Nichia representative who told him that the 90+ versions were not going to be produced

Thanks djozz. Yes thats what I read but couldn't remember the details.

What I plan to order is 20-50 of the following: Nichia NVSW219C 280lm white, 5000k, 83Ra. I’m debating the quantity because I don’t know what the interest level is for these on the forum. Every time I convince myself to just get 20 I find a bunch of excuses why I should order more.

Shipping is the killer, they don’t generally ship to the US, so I have to arrange shipping, and it’s not cheap. This is the main reason I keep thinking about a bigger order, to defray the cost of shipping.

I plan to grab some other LED’s as well. Some for playing around, some for builds.

If they have them in stock you could consider getting some of the 5000K 70 CRI 219C's, they should have 15% more output than the 83CRI version. With a sliced dome (hoping that that would come close to the effect of a full dedome) it should outthrow everything, even the XP-G2 S4 at 6A (which is not possible on a single battery).

They don’t appear to have the 70 CRI version.

Just got an estimate on shipping, $145. :_(

It’s not looking good, I’m not going to pay that much for shipping unless I’m really confident that people are going to be interested in these in the US at almost $10 each for bare emitters.

It doesn’t help that they quoted a package size of 10”×7”×2.5” and 3lbs. It’s hard to believe even 100 LED’s would take a box that big OR weight that much.

Lumitronix was the plan. Even going down to a half pound only dropped shipping to $100.

I have bought some for blf members and am ok to do that again. For 10+ it is ~3.70dollar, 100+ 2.70dollar. Shipping is under 10 dollar.

I'm ok with it if I can send the lot to one person in the states, I'm not fond of sending multiple packages.

I’ll order some through you (a lot). Do you have to pay the VAT tax when ordering from them? I’ll PM you the order details and then PayPal you money.

I have 100 219C’s on the way. I’ll post some up for sale once they get here. They’re the 83CRI, 5000k.

Jos, that testing is awesome! I don’t know how I missed this til now.

I have some 219C’s coming in tomorrow via UPS. Samples directly from Nichia in Japan. The North American Sales Rep tells me there are no distributors here in the US, but these can be bought directly through the rep site. Shame Henry already ordered, probably could have gotten the best deal direct.

I think she had them send me 5000K variants, they are supposed to be the Ra8000 or 83CRI. I’ll see tomorrow.

I have this Titanium X6 from Rey that I was thinking of rebuilding with a Quad, using these. I wasn’t sure what kind of current they could take, but man you sure showed what they’re capable of! Thanks for that, awesome work there. Can’t wait now to get his built with 4 of these and see how it goes…

And yes, this rep told me Japan had cancelled production on the 90CRI variant. No known estimate as to whether or not they’ll pick it back up.

Edit: Checked the email on shipment and they are sending NVSW219CE sm507/D280/L2/R8000

I would have thought that you read it sooner, BLF is large now, I miss threads all the time too. I am really curious what the quad will do with these leds, with this output, low Vf and a touch of F'nDale it might just be close to 4000, with a great hotspot.

I was hoping for the 4K range, I’ve got the light prepped and am waiting for UPS to show up. I could have specified a 2 hour delivery window and had them a little after lunch, for $8. So here I am, waiting. lol

I am using 4 10mm SinkPAD’s under a Ledil CUTE-4 optic in Soft Spot angle of emission. I plan to polish the diffuse surface, don’t know if that will help any or not. I’ve got 2 copper pieces made for the connections, one a disc that will solder to the 4 positive pads, the other a ring that will surround the mcpcb’s and solder to the negative pads. I plan to use 16ga wire to these copper connection pieces for full power capability.

Reckon I’ll go polish that optic and not even bother with checking it in stock form. Wink (anxious)

BLF Ti X6 Quad 219C is complete. Ledil CUTE-4 optics with the face polished, LG HE-4 cell, looks like 4029.6 lumens at start. That was the first quick and dirty reading, I have to get an o-ring or two to finish the light but it’s looking like WOW! and a nice white tint. Just got it done, stuck it on the lightbox. Smile

^ Whoa! That is fricken awesome!  How do you like the tint at that level of output?

 

Thanks for the contact info above.

The tint is wonderful across the board and just insane at max output. Really stoked about it, for sure.

Top Fuel Rail Light

I polished just the cup of the CUTE-4 optics, using my finger tip and Mother’s Billet Aluminum Polish. The optic has cupped faces with a small flat bottom and a point in the middle between the merged quad TIR’s, I left that alone and just polished the cup with the top surface surround still retaining the diffusion.

Never seen an 18650 do 20A before, not one by itself. Freaky.

A monster with good color!

It is weird how this goes, I test a led and tell the world in a convincing graph what the capabilities are (in this case: awesome), but that is not enough for the world, it needs a Frank'nDale and an overthetop flashlight build for the world to really believe it. And the weirdest thing is: it even works for me that way: that is a great mod with idiotic results, Dale!! And I love the way you used copper slabs to distribute the electrical ledboard connections. Smile

(...apart from that the Ti light might not be the best host for a 20A gut..)

^ I for one apologize.  I read this thread when it came out, but I see I didn't post anything.  I try to post at least once to every thread contribution I read.  This thread definitely deserved more attention.

So Dale.  You already have started building some report with a US rep.  Maybe you can see what price you can get us in a US GB?  If not, may you can hand the rep off to a BLF member that will volunteer to host a massive GB.  These emitters will sell like hot cakes.  Hard to imagine how many will be wanted, but it will be a big number.

Love your build up above. Smile

Hahaha djozz, I hear ya…. I had already been talking to the rep when you tested those 83CRI, was trying to get the 90CRI variant. When I was told they’d be out in a couple of months, August or end of, I put it all on a back burner and forgot about it. Then when the 90CRI version was canned, they offered samples of the 83CRI so I accepted. Then when I started trying to find out about this one, I saw your post.

Those charts convinced me to put em in the Quad, I had concerns that they wouldn’t handle the FET driver with their 1.8A max rating. You showed otherwise so I knew they’d be ok in this light.

There’s a massive chunk of copper in this one, and the cooling fins actually do work here with the X6 style. Granted, once hot it doesn’t cool as quickly as Al or Cu would, but I’m a TiFreak, what can I say?

I’ll look into it 4Wheelr, might be that Richard can get us a best price buying a larger quantity. Also working that angle already and getting Richard sold on these. Smile (djozz’s charts speak volumes, Richard likes that kind of testing, more so than mine. Wink )

Sounds like I should have bought 20 instead. So much for selling the extras, I guess I need to find a use for them. Perhaps a run of custom lights, only a much bigger run than I was planning on.

Your price might not be so bad, let's wait when and at what price others sell them for. I will at least get them to you as soon as I have them in house Smile

No worries, they’ll be used instead of XP-G2’s in a run of flashlights. It was the project I was referring to when I backed out of the scratch built light contest. I was already considering them because of the lower Vf and the ease of using a parallel battery configuration and a linear driver, vs series and a buck driver to push an XP-G2 to 5+ amps. My main concern with them was availability, that seems to be a non-issue now. As long as they dedome well and work well under a collar they should be fantastic.

I knew I was taking a risk buying twice as many as I need, but the price break at 100 was too big to ignore.

Ehhm, no one by my knowledge has managed to dedome these yet. Undecided I tried twice with a hot method (did not post about the second attempt), the first try was a total failure (see somewhere above), with the second try I managed to clear most of the silicone but a messy layer was leftover on top of the die, but with the led still working, and I think it will do the job (tint alteration and increased illuminance of the die). It was not something I would dare to sell...

Someone needs to experiment with gas dedoming or slicing.
