kaidomain xpg2 s2 1a are real deal ?

Hi all,

Firstly I would like to thanks RaceR86 for fixing the spreadsheet. Hope your hand will get well soon

I just found that http://www.cutter.com.au/index.php now has Nichia NVSL219B R85 emitters, bare and mounted on aluminum MCPB 10mm, 20mm, triples on 20mm, 32mm and etc. One just have to type: nichia 219b on Cutter's search page.

I also found this link: http://eepurl.com/Rm8x1 posted by dsche in fonarevka forum, link: http://forum.fonarevka.ru/showthread.php?p=497494#post497494 (I hope he doesn't mind I post it here). It's from Cutter mailing list. It compares the spectral perfomance of Nichia 219A vs 219B. It's interesting that these new Nichia NVSL219B has CCT of 5015K, CRI of 91, and outputting 260 lumens at 700mA.

I hope RaceR86 would help to add these to the spreadsheet. Thanks in advance bro

What cutter does not say what id the brightness bin and voltage bin for these Nichia LEDs.

The SW45 should 4745K-4260K. Can really Nichia sell a 4745K-4260K that turns out to be 5015K or that is a SW50 (which does not appear in the Nichia datasheet at R85 CRI)

EDIT they say ordered SW45, 4500K and result show 5015K. Inetersting.

I prefer 4500K more than 5000K+

I’ll add the cutter 219B R85.

I’m happy to add other things you guys find. Just perhaps post it & mark “help adding” or something similar. Usually when I see something posted here I forget that they might not have added it to the spreadsheet.

Who knows.. Kaidomain have been know for claiming top bin on stuff that isnt top bin in the past. Several people seem to be happy with their latest Nichias, and I have not heard many complaints. Ill probably never consider KD a trustworthy vendor when it comes to this stuff (or most things).

The latest XP-G2 S2 from IOS have a pretty nice price, especially considering that they are mounted on Noctigon. Quantity discount is good too.


Thanks for helping out Helios.


Testing XM-L2 U2 4C from Fasttech

Ok, did a simple noobish test.. I used two different lights meters at the same time.

FT XM-L2 U2 4C vs FT XM-L2 T6 4D, both reflowed to Noctigon.

Ceiling bounce numbers in the order I tested the emitters:

T6 4D test 1: 47 and 47

U2 4C test 1: 43 and 45

T6 4D test 2: 43 and 45

U2 4C test 2: 35 and 44

U2 1A (from IOS) test 1: 40 and 51

First meter shows bad consistency. I would recommend focusing on the 2nd number on each test. The U2 3C have quite similar or lower readings compared to the T6 4D. Not anywhere near the U2 from IOS.

My conclusion: The XM-L2 U2 3C 4C from fasttech is not U2 bin. Maybe its T6, but not better.. Not a surprise really...

8 Added - Nichia.

Cutter Nichia 219B R85
Bare, 10mm, 20mm, 3up 20mm, 4up 24mm, 3up 32mm, 4up 32mm, 7up 40mm.

~ edit ~
All 219B R85, 90CRI, 5015K, D240 bin.

2 Added - Nichia

Mountain Electronic Nichia 219 on copper noctigon 16mm and 20mm.

I noticed they weren’t on the spreadsheet.

YAY. Great news everybody.

XM-L2 in "2" tint. THE ONLY XM-L2s in the "2" category. AND, its U2 bin! :party:

I requested these about a year ago.

XM-L2 U2 2C on 16mm Noctigon 6,86$

XM-L2 U2 2C on 20mm Noctigon 6,69$

(order placed)

To clarify they are 219B, they are R85 and they are D240 flux bins. We are spectral testing leds in house primarily because many leds that are min cri spec’d are generally higher so see it as being useful information to denote specific stock bin spectral performance for those that care about that sort of detail

Welcome welight!
Thanks for coming here & confirming that.
The spectral testing is fabulous.

Updated those entries in the database.

Added (found by RaceR86 & JohnnyMac)

Triple 20mm Nichia 219A B11 (Parallel) w/ TIR optic $7.34
Triple 20mm Nichia 219A B11 (Series) w/ TIR optic $7.34
Cree XM-L2 T5-5D 260LM 4000-4300K LED Emitter $4.44
Cree XP-G2 S2-2B 458LM 5700-6000K LED Emitter $2.56

Could this actually be S2 bin XP-G2? Has there been other XP-G2 S2 before?

XPG-2 in S2 bin has been available for some time now

Who knows with FT..

See post 300 for more S2 binned XP-G2s. Not sure why the S2 emitters from intl-outdoor are not to be found in the database now. Ill add those. Again.

EDIT: Whoops. They were added. But I had written R5 bin on them.. Fixed now..

I never got around to add the ones from KD, so I sent you the link. 0:)

I’m thinking the nichia 219 page could use something to separate 219A, 219B & non high cri. How about another column? “Type” perhaps?
219A H1 / 219B R85 is like XP-G / XP-G2

Maybe add an extra Nichia sheet?

Do as you like Helios.

:)

Hey I was wondering why no links or interest in Cree XBH?? same flux as XPG-2 but in 2.45mm package. this led is made for torches

FastTech has bare XP-G2 S2 2B's: http://www.fasttech.com/products/1/10001905/1682200-cree-xp-g2-s2-2b-458lm-5700-6000k-led-emitter

I ordered a few...

Oh, another XP-G2 S2. :bigsmile:
I went to add this FastTech XP-G2 S2 2B, only to see someone already added it. Scroll to see who added it…. Helios. :ghost: Oh, yea, thats right. :weary:

There was initially a thread with excitement for the XB-H but it seems like people lost interest when they realized it appears to use an XP-G size led die. Smaller package but not higher surface brightness that some people want for throwers.

Welight, the XB-H on 20mm star is T4 bin, 1C tint? link
Added an XB-H page.

Yes correct.

I am a bit surprised, same lumens with 5 degree narrower primary beam angle, unless your dedoming in which case it wont matter and roughly 20% lower cost

Ooopsie Smile - I stupidly missed all those earlier posts. Guess I'll find out if the FT S2's are real....
