The dome looks frosted
"Drop-in upgrade" for XP-G's -- nice! Dang, upgrade to my Noctigon triple in a S2? Sweet!
haha YES sweet!!
anyone have measurements of the die? it looks bigger than the xp-g
edit: misinterpreted diagrams…
Same die size as xm-l2->no throw improvement.
X?-L …. maybe 2000 lumen+ we will see
Nope,all datasheet numbers say it's xm-l2,just in trimmed package.
Yeah it says the foot print is 3.45 x 3.45
10 watts in a XP die size? Better use Copper stars and then some. So, XM-L will be 20 watts? But maybe by them they will figure out how to hold the CRI. I wish Nichia would step up and make a larger die 90 CRI led.
Gree will have to call it something else. What's the next letter in line? XR-S or XR-T? Time for the Chinese flashlight manufacturers to step up and make some better heat sinking in ALL their lights.
Based on my calculations I see XM-L2 as having a 3mm by 3mm die, XP-L a 2.7mm by 2.7mm die and XP-G2 at 2mm by 2mm. I resized photos of each LED to they real size and measured the die by referencing the overall size of the LED.
I am talking about the die, not the footprint which the XP-L share the same with the rest of the XP family.
EDIT: I do not think one can rely 100% on the photos as the dome distorts the size of the die in comparison with the overall dimension of the footprint.

Do you not truest Cree to tell you the truth? They give the sizes in the linked data.
XML - 5 x 5
XPG and the XPL - 3.45 x 3.45
Time for cells to increase capacity for high current loads.
Oh Ya, that's wut I'm talk'n bout - I don't care bout the dye, but the mounting is the important part. Triple Noctigons!! Well.. maybe the dye does make a difference with focusing, beam patterns, de-dome effects, etc...
Entirely probable.
I guess you mean the surface area covered in phosphor that emits light? The relevant bit to throw improvements? I had assumed we were talking about which mcpcbs would suit, my bad.
Here's my comparison. The photo provided by CREE for the XP-L is not the best, but in my calculations the die is just a bit smaller than XM-L2.
A picture is worth a thousand words. Is that a rough surface, (pyramids), on the phosphor? Like the MT-G2? If so, then it won’t throw very well.
theoretical 1500 lumens @3a on triple noticon
calling RMM, we have a new product we would like you to stock!!!
I wonder if they are plug-n-play compatible with the xp series carlco optics.
Maybe time for developing a 4.5v battery at about 6000mA and a high drain rating, with very low resistance.
