Cree XP-L, XM-L performance in an XP size package

200 lpw, 1079lm @ 10 watts 85C. Impresses me.

Woah, that’s extremely impressive. I hope it can be driven hard like the XM-L line! Seems that it’s rated for over 1000lm @ 10W, that’s what I like to hear!

Looks like a game changer! Especially for throwers.

When can I buy it? Smile

Some observations:

-Its got slightly lower CRI than XP-G2 in CW. (65-CRI like XM-L2`s. Not 70 like XP-G2`s.)

-Same viewing angle as XM-L2. (125 degree. Not 115 like XP-G2.)

-Vf seems to be a tiny bit higher than both XM-L2 and XP-G2. (It might have lower VF compared to XP-G2 when both are at 3A though)

"Drop-in upgrade" for XP-G's -- nice! Dang, upgrade to my Noctigon triple in a S2? Sweet!

haha YES sweet!! Smile

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 Wink

Nope,all datasheet numbers say it's xm-l2,just in trimmed package.

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 × 5
XPG and the XPL – 3.45 × 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.

"As a “successor” product to the XLamp XM-L2"  Might mean that line will die off then.

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.

If you can’t blind them with your brilliance, baffle them with your bullcrap.

The real currency in the world is not money, it’s trust.

Maybe time for developing a 4.5v battery at about 6000mA and a high drain rating, with very low resistance.

it’s all speculation to this point. possibly removed from the datasheet on purpose to hide variance/future changes
given the cree ‘HD’ trend of xp-e -> xq-e, xp-g -> xb-h though it would make sense the xp-l is the same die size as xm-l (2×2mm)
should provide an interesting test of thermal coupling between the xm and xp packages at the very least!

Having a xp-size thermal pad, the XP-L can expect to handle heat somewhat worse than the XM-L2, at high current. But only testing that will give the real answer.

Could be, that is interesting to be seen as that thermal pad is a bottle neck. XM-L2 and XP-L are both rated 2.5 °C/W thermal resistance.

Yup.

It’s the XML version of the XBH. Basically just an XML2 in a trimmed package…. no no improvement for throwers.

For flashlights, main use I can see is this might be usable on 20mm triple XPG stars. I’m not sure it will fit in the Carclo optics though, as the dome is larger than an XPG dome.

Been waiting for cree to make this public. DBCstm shared info on XP-L two weeks ago. Now, a bit more waiting until its available to purchase.
