Who added the comment about XML best for single cell lights? My XM-L2 single cell builds are better than any XML, where does this comes from? Just use a low resistance battery - so far, best I found is a Samsung INR 2000, lowest resistance of any battery tested by HJK, or a Pana PD 2900 will do nice.

That was me, the reason I added that is because of the exceptionally high vf of the XM-L2. It was around 4 volts and 3.5 amps if I'm remembering correctly, and no single cell can supply 3.5 amps and still put out 4 volts...

I think match deleted the vf graphs for the XM-L2's and didn't re-post, at least not by now. But I've been getting outstanding results for XM-L2/SinkPAD combos with single cell lights, such as C8's (3), HD 2010, and a T10 IO host build. The tailcap readings for the Nanjg boards at 3.85A can't be achieved with standard batteries such as Panasonic 3100's or 3400's, but with Pana PD's or Samsung INR 2000's, I get the full amp reading, and higher lumens measurements.

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.

(Tom E beat to to some of the info)

Added a bunch of XP-G2 emitters form Cutter, and some XM-L2.
Basically I added everything they had. :stuck_out_tongue:

Fixed the XM-L sheet. Someone had messed i up quite seriously.

Added another MT-G2.
MT-G2 group buy in this thread.

Anyone know the difference between 2-step and 4 step?

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.

Ohhh, yes missed them - my bad .

Update 03/26: added an update: KD replied to me saying their XML U2 is a 1A tint - hope I did it correct. Noticed the date is US format now??

Thanks.
I started with EU format on the dates. Now I use US one some (if I don’t forget). Ill try to use US date in the future.

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!

Update:

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.

Thanks!
I just said it was some copper thingy. Nice to get some clarification. (I removed the red text)

Still hoping some have answers on the Nichia emitters in my previous post… :slight_smile:

Added XM-L2 from DX.

http://dx.com/p/20mm-cree-xm-l2-1150lm-cool-white-bulb-board-for-flashlight-black-grey-199058

Ill quote Tom E

Its a clearance sale!
Great price!

Good price on those xm-l2 from IO. If they were a 2c tint i would buy a handful of them heck even if they were 1C i would buy some.

Thanks for the info though

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.
