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.
Thanks for the suggestion. I think it would be a good Idea if the datasheets were frequently updated.
A possible issue with adding an "available column" is that it would easily become another thing that should have been updated, but wont be. There are not enough people updating. Me included. I try focus mainly on adding new emitters and fixing the sheet when it gets a bit messed up. If a link is dead, I suggest to delete the emitter/line. I always do that.
With an "available column" I think we can risk that an emitter is marked "not available", but then the emitters gets back in stock. No one updates it. And people wont bother clicking it because the datasheet says "not available", despite that it is.
I think its better that people sometimes click dead links or on products that are out of stock (and hopefully update them or delete them), then to avoid checking them out due to a column that may or may not be correct about their "in stock" info.
That is my thoughts.. Feel free to do a trial on one of the popular sheets, like XM-L2 or XP-G2 if you think its worth a shoot, and are able to help updating the datasheets. If it something that works, It could be adopted to all the other sheets.
All help with keeping the database updated is highly appreciated. :)
Oh, yea, thats right. :weary:
- I stupidly missed all those earlier posts. Guess I'll find out if the FT S2's are real....
