The results was posted by Match in one of the new generation emitter thread tests.
The data/graps on vf was later removed by him. Might have been due to inaccuracies?
The data/graps can still be seen here.
If you look at Cree`s datasheets, vf on XM-L and XM-L2 you will see that it is the same. 3,33v @3A.
As long you use an aluminium pcb and are at 3,5A or lower XM-L2 will always be better than XM-L on a single cell on high as far as I can see. That is how I would guess most emitters are driven in single cell lights. If using better cells, you can push a bit further.
I think it would be better do just write.
“About 20% brighter than XM-L” on the XM-L2 comment.
I didn't notice IlluminationSupply on the list - just bought some XM-L2 T6 3C's from them, think they still got them. The U2's are on back order, Craig mentioned April I believe.
You mean the bare emitters?
If you sort the list for bare emitters you will see several from IlluminationSupply. There is more than 40 XM-L2s listed…
The second picture in the first post shows how to see if some emitters are not listed.
Added LEDs from: http://www.theledstore.com.au/ into the spreadsheet.
Lots of Nichias at great prices. Some nice multi emitter boards. They have the best prices on Nichias and lots of them in stock!
Added some XP-G2 multi emitter stars (7-leds) . Same as from Mouser, but slightly higher price.
They will get MK-R on star at a good price (added the info they had). Only place I have seen with that emitter on a star.
As far as I can see. To Norway (in Europe) shipping price is from 14 bucks. Slightly cheaper than Cutter it seems.
Thanks.
Added:
Triple XP-G2 on 20mm star. cool white and warm white on
So far, only source with warm white triple XP-G2 on 20mm star.
I doubt I will ever order from this store. Shipping was 22.50 for some parts… But probably nice for US people.
In general, where do people get their optics from? Im thinking more on the special stuff (3xXPG on 20mm board etc) Stuff that you cant make by buying single reflectors.
Anyone know of some place with free shipping?
This thread is now a sticky. It has been moved to the modding forum from the led light bulbs forum.
Added some emitters from LCK-LED. XM-L U3 on some copper thingy… 10$
(I gave it the red text like the proper cooper PCBs )
XP-G2 14/16mm (warmwhite and coolwhite)
4.65$
I have sent mail to them about tint/bin.
Like LEDDNA, this is a good source for warmwhite XPG2s. Price is great!
Helo have added XP-G2 from DX.
Unknown bin/tint. But nice to see that they get some newer stuff.
Got mail from LCK-DNA.
Updated BIN/TINT info on their XP-G2s. (R5 1A and 7D tint for WW)
I think Illumination supply deserves:
“no, but not expensive” on the free shipping row. I have edited the text.
Most other stores with “no” free shipping have much higher shipping prices.
Questions to everybody
I came across Nichia emitters from Ledrise. (Thanks to DBCstm for linking to it in another thread.)
I was not able to see the typical “famous” 4500k version .
But isn’t this basically the same only in 3000k? Its H1 and 92CRI…
And this the 5000k version? (Seems like a higher output, lower CRI version)
I wonder how it compares to 5000k, NW XP-G2.
No copper there, just some FR4 with vias, appears some manufacturer is trying to fool sellers, some users know what I am talking about. You can see the sandwiched layers, so watch out what you say.
As long as nichia allows one to consistently order a single color rank. Looks like nichia’s “color ranks” for the NVSL219A-H1 can range from ~3000k to ~4800k.
“Producer Code NSL219AT-H1 S27” Might indicate rank sw27 (3000k)?
Isn’t the more neutral tint of 4500k the reason its popular?
Cree has 2600-3200k in 90+CRI but only nichia can give you 4500k in over 90 CRI.
And I believe you are correct about the 4500K/92CRI is the magic formula because Cree needs warmer tint to achieve same CRI. 2600-3200k as you said.
I added the two emitters anyway. Just in case someone wants to to a comparison between the 5000k version and XP-G2 NW. (I believe DBCstm had a 5000k Nichia)
Or 3 3000k Nichia vs 1 XM-L2 S6 3000k (90 CRI)
Thanks!!
If you don’t mind, I made it into three rows (14/16/20). Makes it easier to sort that way.
intl-outdoor sell same product cheaper as the spreadsheet shows, but If I understand correctly these can be bought mounted on their copper PCBs for 1.25$ extra?
It sure looks like that.
I edited that into the comment if you dont mind. That way its only one price to sort.
Their Copper PCBs was discussed a little earlier. It seems they do not offer the same heat transfer from the led to the PCB due to the dialectic layer on top of it.
(The middle of the LED is not directly on copper it seems, so that should make the in a “league” below Sinkpads).
Im thinking about adding another sheet for PCBs in the near future. Several places offer copper PCBs now/soon. And it would be nice to know were to buy empty PCBs for multiple emitters too. Therefore just making another sheet for them instead of that little bit on the Information page.
Maybe adding TIR optics too?
I wont bother with reflectors!
