A bit bigger than the XM-L colour, but with way more output, ~XP-G size dies, : 1040 lumen for the white chip, 680 lumen for green, 360 for red, 4.7W for blue, this is for 4.5A per die .

Not sure how interesting it will be for flashlight use, at least I'm pretty sure it will be way too expensive

Wow…surely there’s only one use for something that pretty! :wink:

ROFL!!! :party:

Wonder what the forward voltage is on these.

I wish Cree could put that clear flat dome on their led as an option

@djozz - nice find. XP-G sized color dies are interesting. I took a look around for single die versions. I couldn’t find any “red” 2 square mm ones in single die packages. I’ll be more interested if they start doing single die packages with those.

Here’s what I did note while I looked:

  • 625nm is as at the upper (more red / more deep / more saturated / whatever) end of Cree’s allowance for their ‘normal’ red LEDs (620nm to 625nm). [I do not see an equiv to Photo Red / Deep Red, although they do have some low power LEDs labeled “Hyper Red” which are slightly deeper.
  • All the red power emitters (there is one ‘hyper red’ power emitter) seem to have 1mm square dies. They’re all rated for 1 amp and seem to have roughly similar performance to Cree’s equiv product.
  • Interestingly all of OSRAM’s projection LEDs which I looked at seemed to use amber rather than red!

@LinusHofmann - nice :wink:

@AlexGT - I think OSRAM and Luminous both call it a “window”.

No that is the old version, less than half the output, the new one above is bigger and handles way more current. It was announced the 9th of december, I'd be surprised if it was for sale already.

also available in multiple layouts:

RGBW, LE RTDUW S2W, datasheet (OP pic is newer edition)

cool / warm white, LE CWUW S2W, datasheet

amber/ 2 green / blue, LE ATB S2W, datasheet

4 white emitters, LE UW S2W,

all emitters are in the 2-4v range, and at 4.5 1.5 max amps. 5.7 mm x 6.4 mm package.

Edit: doh, these are the older models….

10

@musicmagic: those are also the old type with smaller dies and less output.

BTW, I'm curious if Cree is going to make high CRI XH-P emitters by mixing different dies in thd array like this..

11

i like that cool/warm white version. Built a driver that can be variable output between the warm to cool white dies to custom set the tint you like best.

12

OH WOW!!!

Up to 2.6 times the brightness from a component surface only 30 percent larger

With an area of 2 mm² each, the chips are twice as large as the previous ones but at 5.7 mm x 6.4 mm x 1.3 mm the package size is only slightly larger.

Imagine that in a zoomie :smiley:

Even with a 105C/D w/ 4 extra chips…that thing would make some MASSIVE light!

Wonder if a 16/20mm noctigon/sinkpad is available

Technical data (LE RTDUW S2WP):

Package dimensions
5.7 mm x 6.4 mm x 1.3 mm
(previously 4.8 mm x 5.9 mm x 1.23 mm)

Chip size 2 mm²

Chip colors
Red: 625 nm
Green: 530 nm
Deep blue: 453 nm
White: (x=0.32; y=0.33 to CIE 1931)

Brightness (at 4.5 A, max. DC typ.)
Red: 360 lm
Green: 680 lm
Deep blue: 4.7 W
White: 1040 lm (previously 290 lm)

13

Maybe this will work as good as a sinkpad?

Gee, I wonder who will be the first in line to try one of these out? :wink:

14

i would love to build a light around this led

15

Dude, must you perfectly guess every project I’m working on before they’re done!!

16

hahaha how did i know you would do something with these leds.
i was even gonna pm you to this thread.

17

That’s a cool idea! I’ve contemplated modding a multi emitter light (like a solarstorm 5t6 or similar) like this with a wide range of tint bins of the same emitter. Each led individually switchable to easily show people what LED tints/temps are and how they compare. Might still do this just to use up my stock of variously binned x-mls :slight_smile:

18

I would love a led with 4 different white bins

3000k
4000k
5000k
6000k

All maybe High CRI
Would be a killer quality light.
