Are you sure you mean XP-C?
Thatās a 1 watt LED with super tiny die.
Any chance of really warm white, like 1800 - 2200 K ?
By the way, any request for 219B sw45k 9080?
- Clemence
Yes, Iād prolly order 8-10
Uhhmā¦XPE perhaps, Iāve never seen XPC myself. What I know is itās smaller than the small XPE.
Only NVSLE21AT-E sm2050e D180 R9050 and NVSLE21AT-E sm2250e D200 R9050 would probably interest your attention I guess. Thatās the highest flux/CRI available. And expect one step dimmer (D160 and D180) for these.
O, i though the average 219 had an XP-G size die.
In fact, iām quite sureā¦
Strange how very warm LEDs seem to have relatively less deep red.
I thought it was a matter of how much phosphor they put on the blue / purple āpumpā.
Thatās why Iād still be tempted. 
:laughing: Jeroen, we were talking about NCSx219B. Not NVSx219B.
Die size:
NVSx319A > NVSx219D > NVSx219C > NVSx219B > NCSx219B
I would be in for more 219B SW45 R9080. I would also be interested in 219C 4500k if that is available.
I went crazy on 11-11 and got a 2000K striplight and 2000K car-bulbs for later scavenging. Weāll seeā¦
Canāt find the 1800K Stanley LED, at least not without paying 2Ć more in shipping than the LEDs cost. Youād think they were ExplodingFire rewrapped Li cells or something.
219C sm45x only available up to R8000
BTW Kyle, have you checked my PM?

Aha, i see.
Never knew what those letters meant t.b.hā¦
ā¦but, but, but, i think i would want them to have a lot of deep red though, so R9080 or better is highly preferable.
because such warm white should resemble a dimmed tungsten bulb, or a carbon filament, or a candle or kerosene lamp.
Cozy. 
I know, I know. You didnāt like that 3pak of superwarm Nichias at Fasttech, either.
In for 10-20 pcs.
SOLD
OK, I decided to sell this Tiara C1 Pro. I modified it right off the box, only simple LED swap to 219C sm4070e R9050 and changed the TIR optics (bigger and even hotspot than the OEM).
The reason: Iām getting used to my 144AM sm573 R9050 worklamp and the non removable magnet USB charger is somewhat annoying. It sticks to any ferrous stuff on my messy bench too often. Iām sure other will love this feature.
The glass lens isnāt included. I broke it to safely remove the bezel with very little damage. Without the glass itās far more resilient (once the glass break water will seep instantly).
Youāll find it in my store (if someone donāt get it while I type in here). Price is USD 65 + 5 (shipping)

sm5770e or sm5750e? The latter is the most consistent (less variation between batches) and tighter than even 3 steps, while still below the green zone.
For me 5750e is perfect please (which is mostly the Cree 2D tint). I only like rosy in warm yellowish tints, but in cool tints for me too rosy is just as bad as too green or blue, it must be near true white (the R9050 must make the colours, not the tint).
Totally agree about this. Not many people are like us Jos. This the same way of thinking. High CRI should be as close as possible to true natural colour IMHO.
Any other thoughts? If itās possible Iāll try to accommodate both ārosyā and āneutralā fan. Any āgreenā fan around?

Sorry to disappoint you guys. Nichia just dropped my request. 3 steps is the best we can get. The special order request is just too small for such a tight bin 
And Iām not going to purchase a full reel of sm5750e D220 9050 219C (the flux rank available for that bin)
Letās drink the beer 
Pity, but it is already awesome what you achieved thusfar in getting premium Nichia leds for us mere hobbyists!
Letās see how long I can supply these exotic Nichias. There are rules to be followed ā¦
This was really just a hobby for me too. But I have to turn it into professional manufacturing to keep it going.
