Datasheet:

Summary:
8% increase in lumens per watt (max bin on datasheet is S5 vs S4 for Gen. 2) :slight_smile:
Slight decrease in voltage requirements (~0.1V less at 1.5 amps (both at 85°C) :slight_smile:
25% lower thermal resistance (3°C/W vs 4°C/W) :slight_smile:
Wider spatial distribution (125° vs 115°, suggests larger emitting area to me) :confused:

Wanting XP-G3 Hi……

looks very promising. when can we have it!

Hmm.

They can officially be heavier driven too.

“up to 863 lm at 2A”… G2’s were only rated up to 1.5A…

Sounds great!

Maybe reach over 1000 lumens at 3A?

Obviously shares the same footprint… but wonder if the die size is bigger to make it able to do this (lower lux)?

S5 bin looks nice!

Also notice the forward voltage is lower… so slightly more efficient… not XP-L or Nichia efficient… but any gain is good.

Yep, datasheet stated forward voltage of 2.99 vs 3.1 at 1.5 amps. 3.06v at 2A at 85C. Nice.

Hmm, yeah, the viewing angle is the same as the XP-L… :person_facepalming:

If I need a flooder, then I would still go with XP-L by the look of it… can be driven harder, and also more efficient…

XP-G3 is looking less promising now… A “cheap version” XP-L?

XP-G3…

Cree got new cook and I really don’t like it…

Probably nothing will change with G3… It can be only worse like this one

Joehoe!!

More lm/W is always very interesting. I like also that it says to have 90CRI versions in all colour temperatures, that alone makes this a great led IMO.

From the provided picture: almost all leading led manufacturers now use this way of applying the phosfor: after the assembling of the led. This could mean trouble for dedoming :confused: But who knows Cree comes out with a HI version of the XP-G3 soon, not the throw of a real dedomed led, but at least the next best thing.

Who ’s getting one for me to test? :wink:

80 CRI minimum at the S3 bin and at higher color temperatures looks like a big improvement. 80 CRI min S3 down to 4200k as well.

Well it looks alot like the old XTE emitters, if it performs like that its definately not desinged for flashlights, yet i could be wrong, we`ll see soon enough

I’d wager that you’re definitely wrong unless it doesn’t work with all of the existing optics designed for the XP platform.

Different specs compared to xp-g2:
Current 2A vs. 1.5A,
Thermal resistance 3 vs. 4C/W,
Viewing angle 125 vs 115 deg
Forward voltage 2.89 vs 3.00V @1A

There is no doubt, die size has been increased,so another fake “improvement” from cree.

But if the die size is increased why not just call it an XP-L which is an XM die on an XP footprint??

Waiting to see which one of us tries out the new ‘toy’ first :wink:

The press release does make the claim of improved lumen density, which is a key ingredient to throw, though.

And off of that… If there is an improvement to lumen density, then it’s a better thrower. An increase in die size couldn’t hurt anything, so it becomes a non-issue.

I compared dimensions of both the XP-G2 and XP-G3 from cree data sheets and their dimensions are identical. However, die size itself is not mentioned anywhere.

This is important.

Please someone send them to Djozz…
