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...
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
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
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. 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.
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
When that is said. For most modders (who like their amps high). 2,99 -3,99$ mounted on Noctigon from IOS. Then you could also be (more) certain that you get the correct bin and tint. Hard to beat that.
@RaceR86:
You started this great project, so I want to ask you about one thing:
Is it ok for you and most others, if we modified the list with a "available" column?
At the moment I need a XM-L2 U2 with an aluminum base (replacement for a SWM C10R - on high only 0,9-1A - copper base is not needed). INTL-outdoor has a XM-L2 U2 for under $5 nine months ago, but do not listed this at the moment. Maybe it will come back and deleting the line in the data sheet wouldn't be the best solution. A new column could help and if someone find a not available led, he could post a "not" with date and colored the field red for example. If it is avaialable later somone could delete the "not".
Maybe someone else have a better idea, how this could be marked.
