Lets make this thread a sticky, it provides valuable info to us modders. Thank you for your hard work.
On a side note, the link to the xhp70 led seems incorrect

Nice testing job! :party:
Thank you for everything, don’t stop 
Thanks for the nice comments :-) (was not the intention, it is all old work)
corrected the link, I hope the rest works ok
Hi djozz, lot of charts, but no V1. The one I am trying to find…
I already use the 219B V1 sw50 (5000k) @ max 2,4A* for momentary use, without issue, so far so good. It replace an old XML-T6. Temperature management seems to be more an issue than tint shift, get hot fast… Anyway, not using max for more than 1mn.
The 219C’chart you released lately looks great for a 80CRI. Do you think it would be possible to replace a XP-L HI with a 219C (I don’t mind loosing lumens, but the XP-L HI is really too cool) or it would be better to simply use a XP-L warm high CRI?
Even tough the 219C has some slight turquoise tint, the CRI is nicer compare to factory XM-L2 and other Cree cool white emitters…
Still prefer the 219B-V1 as a high CRI neutral white but above 2.5 –3A the 219B-V1 may fry easily…
I would like to build a high CRI thrower single 18650… But with a reflector larger than ET sticks…
(*2,4A was measured with XML)
I was also wondering:
If a dedomed XP-G match the beam profile of a dome XP-E, does a dome 219C (which is close to a XP-G) would have the same beam than a XP-L HI (which surface is wider than XPG/219B and equivalent to a XP-L dedomed) within same reflector, of course…
Anybody some ideas?
Thanks a lot Djozz.Your posts are “go to” posts.
great work djozz!
and all collected at one place its even more impressive…
The 219B-V1 I have been using have a nice low Vf. Had a triple hooked up to a 105C 8*0,35+6*0,38 and guess what: Even with my very long and thin dmm probes I got 5.08A!!! I wouldn’t try these with a FET-driver, not even a triple, way too much amps, too much heat generated. A member of the german forum fried a triple with a FET-driver, got over 16A initially.
Outstanding work djozz! Keep it going please, very appreciated.
That is a nice thing to look forward to. I was indeed planning using a FET-driver, but in a 18350 host, so that may just be perfect .

Thank you very much Djozz.
I made some X6 triples lately and wrote a build thread in german and I compared different emitters under all different kinds of CUTE-3-SS optics. I’m afraid you won’t see the images from the build and optics comparison without beeing logged-in, but: I think the beamshots should be visable to everyone. There are two X6 triples with B-V1 and some more lights, have a look if you’re interested.
Thanks for your work Djozz.
djozz, thanks for consolidating all your invaluable work!
CityCoffee, I was planning on running the 219B V1 @~2.5A but you say that’s too much heat. Was it more heat than the XML it replaced? From djozz test of the previous 219B I thought it would be fine but I guess I might have to run it slightly lower.
Thanks for all you hard work. This is an awesome resource. Your skills are very much appreciated!
Regarding the temperature @2.4A I made this remark just based on memory. Also, some driver behave differently according to the emitter vf. (I cannot guaranty you that my V1 is driven at 2.4A)
2.4A was measured by another user with factory XML emitter. On my side, the tail cap measurement on burst mode cannot be done with my tester at all (?)
According to djozz, the V1 is between the 219B and the 219C… The question is:
How close to 219C 
djozz chart shows some very good performance from the latest version and seems to be indestructible. On the other side, the 219B is far behind…
I believe that the 219B V1 can be used (for momentary period) around 2.5A without issue.
Without good test (djozz’s style) I would hesitate to associate a 219b-V1 to a 3-3.5A driver.
Apparently 219C is “very” fine at this current. (Nichia even set a max @ 1800mah vs 1500m for other 219b…)
Again, what would be nice is a 219C CRI90 sw45 or sw50.
Something very nice with the 219B-V1 is it’s neutral white characteristic. If you are used to warmer emitter, it may even looks too cool (especially with the sw50)
Other 4-5000k NW led do not make the red and yellow pop-up as the Nichia does. Finally, compared with a cool-white it makes the v1 looks off-white again. Weird but finally, it is what should be a true neutral white> no hue perception and a good color resolution.
I believe that some 3000k can provide a good CRI but with a strong orange hue.
Non high CRI neutral white (XML) need to be pushed to clear-up the greenish tint associate to them. Annoying…
Hope that someone manage to test more in details the V1… H)
Thanks djozz for putting all your great work in one thread!
Nice Collection
Could bot find the crashtest of xml and xpg in your List:
These measurements are always the first place I look to get an estimate of what’s possible and expected for anything light-related. Way more useful than the official specs.
Very helpful reviews.
By your chart for the xp-l vs xm-l about 950ma will produce 500 lumen and 3000ma will produce 1000 lumen. Suppose you take two of these leds wire them in series then the same for another pair. Now wire the two series pairs in parralel. The overall impeadence should be the same as a single led. Now drive this at 2000ma, to give each leg 1000ma. What would the voltage be? I assume 1/2 so the total voltage would have tobbe doubled.
Would you not now get 2000 lumen at only 2/3 the current for a single producing only 1000 lumen? as the wattage is i suared x r. Am I not now producing a lot more lumens for a lower power consumption. Or is there a flaw in my reasoning?
