New XP-L High Intensity Emitter

The good news is, they work! These will fit under the 10507 optics on a Noctigon triple star.

I used a 1mm thick stainless steel washer to control the depth of cut and a scalpel to do the deed, shaved the domes off 3 XP-L V5 1A emitters on a copper star. Then I removed the emitter and re-flowed them onto the triple Noctigon, placing the stack of copper 20mm SinkPADs on top of the 3 shaved emitters to ensure they were seated low and not held up with solder.

The optics fit on perfectly! And the 1A tint is still showing, a slightly blue/white output on the white styrofoam ceiling tiles in our house. Excellent!

The bad news is, I don’t have funds to buy a full reel of these. :frowning: lol

Are you asking whether a single XP-L will be brighter than a triple Nichia? Or triple vs triple?
The short answer is that any XP-L will easily outperform a Nichia, and a single XP-L is capable of way more than 1000 lumens. The Nichia has the advantage of better CRI though.

Thanks so would a triple XPL dedomed in a sinner 18650 copper host be good or a triple nichia in your opinion?.
Wondering if these XPL are available in cool white too.
Looking for intensity I guess.
Is one XPL enough or 3 in that host?.
Thanks.

People have gotten 4000+ lumens from triple XP-L set-ups. It’s up to you how hot you want to run it.

Yes, current XP-L’s as well as these new versions are/will be available in all the usual tint ranges including cool white.

The only real answer there is triple XP-L , shaved, under 10507 optics.

I just found that using a 1mm thick washer as a guide, with an XP-L mounted on a 20mm star to hold the emitter and be a base for the washer, I managed to shave the dome off clean with a scalpel. These fit under the optic without altering the optic and don’t seem to have lost tint. So the triple XP-L will do some 3000 lumens and be as intense as you could hope for. :wink:

This is awesome news!

I am seriously interested to see how the tint bins will shake down. Whether these will be available in different groupings (all greener perhaps? bringing back the 2S 2T bins…eek! :P) or if the thin dome interface layer allows them to use the exact same phosphor process and yield the same tint spread as fully dome leds which would be awesome!

Of course hoping for the best case scenario where extra effort goes into producing great tints hard to achieve by diy dedoming today AND a lack of tint shift across the emission angle because of no dome. Bye bye cree rainbow?! Fingers very crossed 8)

Also great to finally see some hard datasheet facts on the difference between a domed and (at least a partially) dedomed emitter. The output bin differences are already interesting but I like the direct comparison for the emission intensity profile of a dedomed emitter vs that of a domed XPL.

Great stuff Cree!

So, what happens if you drop one on the carpet :stuck_out_tongue:

Does the Meteor have a Disco mode?

I wonder which of our members are Cree employees :slight_smile: I know i have seen some that claimed to be ex Cree over at CPF.

I mean i you search for a specific Cree emitter on google you end up here, they have to know about this place.

So what do you guys think, do they have such an airtight NDA contract, so they can only lurk or what, this new XP-E2 Torch & the XP-L HI domeless emitter sounds to me like they are listening :bigsmile:

And i would hope that if you work with emitters all day, you are still passionate about them in your off time, hehe or who knows maybe browsing BLF is considered “work time” over there :smiley: if not it should be :wink:

+1 I agree. :wink:

I recall one BLF member being a Cree employee but it didn’t sound like he was in R&D.

Yeah, but if he’s friends with someone in R&D… :bigsmile:

Was that bose301s?

pct.cree.com lists XP-L HI V3

so here we go:

@ 3000 mA, Tj = 25°C

XM-L2 U4 : ~ 1282 lm

XP-L HD V6: 1251 lm

XP-L HI V3: 1095 lm

Or, look at it another way. At bin V3 on both XP-L HD and the new HI, they are exactly the same at every current level, so both are 1095 lm at 3A current. The difference is that the XP-L HI doesn’t have the higher bins. Okay, maybe those will come in time. Looking at the difference from XM-L2, though, it seems we’re going backwards. The closest bin level to being comparable to the XP-L bin V3 is the XM-L2 bin U2. At 3A current, it gives almost 30 lumens more, and the Vf is 3.43V compared to XP-L Vf 3.46V. Then, you have two more bin levels, compared to the XP-L HD having four more bin levels, and still can’t reach the max lumens of the XM-L2. So, the XM-L2 puts out more lumens/watt than the XP-L emitters. Why? Aren’t they supposed to be the same die?

I know they are exactly the same at every current level, just wanted to let people know that there’s a V3 already listed, because in the datasheet there was V2 as the highest flux-bin for the HI version.

As for the XP-L vs XM-L2 comparison, try to look at the XP-L not as a replacement of the XM-L2. It’s a different LED that can fit in places where the XM-L2 can’t. For example the 32XP noctigon board combined with LEDIL optics is a winner. Now with the XP-L HI, you can probably fit them under carclo optics without having to modify anything.

Again, the XM-L2 isn’t replaced, they still come up with higher flux-bins, now U4! I think those are only good news.

With dedoming, you always have a loss of total lumen output, tint shift, possibility of damaging, possibilty of ripping off some of the phosphor and if everything goes right, you end up with a much more fragile LED (if not resealed). Never been a fan of dedoming because of the above mentioned reasons. With the XP-L HI you have less output as well, because of the lower bins, but you’d get less output by dedoming anyways. According to the datasheet, the HI version gives a 120% increase in lux over the HD version using the same secondary optics, if that’s true, than this is more than I’ver ever seen someone achieved by just dedoming.

In a few months, you’ll find M2X Javelot competitors all over the place. Imagine the M25C2 Turbo with a XP-L HI…
Imagine all those sub 30$ lights that will do 100+ klux in stock form.

As mentioned before in this thread, this changes everything!

That M25C2 Turbo looks crazy, to bad its crazy expensive also, i hope some Chinese budget light maker clone that 92mm head with a single 18650, for an more affordable version :wink:

@ cajampa
exactly, that thing is a beast but it’s damn expensive. We need more lights of this type, but cheaper and with XP-L HI :wink:

I need four of these now. I wonder would they handle 5 amps each in my quad-DST thrower project.

Did they just put a clip on that light?
