XHP 35.2 HI Released

I signed up for the Cree newsletter:



Extreme High Power 12 V/12 W/1400 lm; XHP 35.2 HI Joins Its Sibling XHP35.2 HD

The new flat-lens XHP35.2 HI offers outstanding performance in premium indoor, torch, and other candela-focused applications. Available in a full range of CCT and CRI options; shipping now.

Data sheet and binning information here.

I might be wrong, but wasnt there a 35.2 HI already?

Wow, Cree remembering that flashlights exist.

Woah! Finally after a lot of years we get the HI version.

Yeah, want to see someone test it soon. But I won’t hope much with Cree, lately.

I really hope that we can get 90+ CRI bins from mouser at cut tape quantities.

These would be perfect in moderately powered EDC lights.

And i hope they will add "min quantity 1" instead of 1000...

Maybe we can persuade Neven (Led4Power) to buy a whole reel, so he can offer them (soldered onto a board) on his website anytime soon. :-P

Oh man that would be awesome but i kinda doubt his site will be up any time soon :(

Wellp, to me that is not the problem, we will have plenty (I hope) to purchase here and there.

The problem is that, as far as we have seen, Cree doesn't really care much about far exceeding “color rendering minimums”, or to say it otherwise they don't actively look after things like CRI95+, R9 > 90, high and balanced R9 to R12, etc. Until now all high CRI reviews of their leds have been… not bad but “less than astonishing”. I hope this is to change sometime.

Yeah, the R9 values and the above blackbody green tint always betray the Cree emitters.

What I’d really love is a Nichia 144 without the donut hole issues, or a bigger xhp70 competitor.

Since Luminus has SBT90.2, I don’t understand, why Cree does not do anything about it.

For some applications, SBT90.2 is simply too much power.

I think, something like XHP50.2 HI could be a good solution in between.

I guess the newly "upgraded" Olight Warrior X pro, coming soon, is one of the "first" to be fitted with this Xhp35.2 led ?

A little preview is available on the BiliBili video Network (similar to Youtube) (short beamshot preview at 2:50...)

With a 'thankyou" to the poster Flashlight Player.

Thanks,

M4D M4X showed it on FB and IG with detailed view

Here is a few more beamshots for the latest Olight Warrior X pro with Xhp35.2 ...... (link to original post on Baidu)

Some highlights (for those unable to use above link)

On high/turbo max. 2,100 lumens: 1 , 2 (little foggy but still "good penetration") , 3 , 4 , 5 , 6 , 7 .

After downshift from turbo to 1,000 lumens: 1 .

At low mode 300 lumens: 1 .

With a big thanks to the Baidu Flashlight Community and the poster 150_t_l_98K.

Thanks for sharing! Tint doesn’t look as green as the original Warrior X Pro! This new emitter really makes it a practical all purpose light. I don’t use my Warrior X Pro because I don’t like the tint despite I really love the design and build quality.

Now that Cree has sold off their LED division Cree Sells LED Arm to focus on developing better semiconductors, we will see what happens. Maybe IDEAL Industries will pick up on the enthusiast market and develop LEDs that are good for flashlights rather than street lighting!

We'll see. Pray for it / ask the Creator if you will (psst! Always in present tense), it is best to use our powers rather than just looking forward.

At this point, though, I am not very thrilled with the present led technology. With this I mean leds whose spectral power distribution is a mixture of directly pumped visible radiation plus phosphor converted radiation, i.e. the typical blue pump phosphor converted led emitter used nowadays. The wrong thing about this not only are the usual issues with their spectral power distribution curves (low CRI and such), but the absolute crap which you end up with when the emitters are used in conjunction with an RLT collar, which is a consequence of the limited frequency band spectral emission of the parts which receive the recycled light, i.e. only the phosphor emitted frecuencies get the boost and thus both tint and color rendering ability are destroyed (even more).

The solution for the above problem is to migrate to a new type of led, which would be using a pump of frecuency outside the human visual range (UV pump, for example), a pump of course to be used fully in stimulating the emission by the phosphor layer, or using another pump technology (an electron emission pump, like CRTs in the good old days, or whatever) for such duty. What I mean with this is that the phosphor layer must emit all of the expected spectral power distribution. This way RLT collars would operate normally with such led, preserving tint and color rendering ability.

How about a thread for a discussion about this?

Here is a (p)review for the ....

I’m still waiting for the automotive industry to start using proper LED solutions. All these cars I see, even 30k+ cars, with cold, low CRI lights, awkwardly focused and PWMed at ~200Hz.

Maybe then Cree/Nichia/Luminus will have to make decent “XHP”-class emitters.
