Luxeon HL2X

Looks like Lumileds has a successor (?) to the Luxeon V2 – the Luxeon HL2X. Physical construction looks somewhat different, almost more like a Samsung LH351C or D…

Interesting! Hopefully they add more CCT options; 3 seems pretty limited.

The 4000K is more efficient than the 6500K(!)

According to the datasheet the typical light output at 2A would be around 700 / 750 lumen.

They already have more CCT’s listed on the big part sites so it’s inevitable. However, 70 CRI only baffles me. Producing a new LED with one CRI seems so….

Huh, should have googled it when I found the HL2X on the Lumileds website, looks like they are coming out with 80 & 90 CRI variants: here. Also, it appears Mouser is already listing it and although I couldn’t find comparable reel sizes for the Lumileds TX, it looks like the HL2X is roughly half the price.

This is one I’m excited about.

The datasheet is updated to show 80 and 90 CRI.

The more I look it just looks like a slightly tweaked Luxeon V2, which is probably not a bad thing cause that is a decent emitter.

It appears like you could order 1 of each from DigiKey:

https://www.digikey.com/product-detail/en/L1HX-4070200000000/1416-L1HX-4...

https://www.digikey.com/product-detail/en/L1HX-5070200000000/1416-L1HX-5...

If you click on lead time on the 4000K it shows today and the 5000K shows 10/1, YMMV? I’m not going to be the guinea pig on this one since it’s only 70 CRI atm, but maybe someone else wants to be.

This is great news (90cri) Big Smile

Really have a good feeling about this one

Same. I’m still playing with 70CRI V2s, so I’d be interested in trying both.

Currently I have a newborn daughter and complete parts in-had for at least ten separate builds/mods though, so it will wait.

Mouser has 90cri part numbers non-stocked and a few 80cri as well. Most of the desirable ones are 4000 MOQ. 3080, 4080, and 5790 however are 1 MOQ w/ 10wk leadtime. I don’t know if this is a mistake but I’m going to order some 5790s and see if they cancel my order.

I think I’ll order some 4080. I happen to have an XM-L2 “Easywhite” (nominal 4400K 80+CRI) in my SC62w to compare to…
It could be cool to forget about them completely and have them arrive next year!

Actually, the 4080 and 3080 say they are stocked and can ship immediately.
$7.99 minimum shipping so I grabbed 5 of each 3080 & 4080. I really hope someone can scrounge up the 90CRI parts for testing.

Mouser wants 4k+ as you said, and Arrow wants 20k+ for MOQ. Can’t find it anywhere else with quick googling.

If the tint on these are as good as people say the V and V2s are, then even 80cri could be a pleasant beam. Unfortunately, I’ve become so sensitive and spoiled lately that I really have a hard time accepting less than optimal color reproduction. Skin and wood are dead giveaways to bad spectrums and I happen to have a lot of that around

I either missed that last night or it changed since then. I wonder if they were on order already and just came in. Sunday seems unlikely, but who knows. Hoping the 5790 responds to slicing like the lh351d and warms up to mid high 4000s. Otherwise, it’ll be a daytime only light

The V and V2 are so good I still use them despite the 70CRI, and in the case of the V despite the 4040 footprint.

No, if you like your CRI and don’t need more output, don’t bother.

I have 4000K Vs in my D4, and 4000K SST-20 in my FW3A. I compare them best using three of my cats (the three with reds and browns in their coat). It’s pretty significant. The only way they look better in my house than under the SST-20s is in direct sunlight. The Luxeon Vs manage something similar to my house lighting, which should all be 80+ CRI 5000K LEDs.

Where they really shine is comparing to anything Cree ever made. I also really prefer the V to the SST-40. Performance is remarkably similar and warmer CCTs can be had, plus they fit (barely) under Carclo optics. And in reflectors there’s no noticeable tint-shift across the beam to me.

That last part of that is what makes the largest difference for me. Even high Duv can be adapted to if they’re isn’t another reference source, but tint shift is the devil. No way around it. It’s its own reference.

If they can make a 4000k 90CRI emitter with the same or similar tint as the Luxeon V2 4000k, that would basically be the Holy Grail. I will eagerly await the test data.

Hey the 4090s are now MOQ of 1, even though they’re backordered, so I placed an order. Estimated lead time is ten weeks so it’s time I forgot about this thread for a while again!

I have 10 in my cart right now along with 4080s and 5790s. Also snagging some new HHL532.TK emitters.

Gotta see these things! Ordered qty 10 of the 3000K 80 CRI, qty 10 of the 400K 80 CRI, and 3 of the KW HHL532.TK.

For the KW HHL532.TK's, not sure what size, if they are 3535 or not.

They’re weird. More like a 3737 package with a 3030ish solder pad. Non-neutral thermal pad (cathode)

So they are a no-go on a DTP mcpcb it sounds like?

In a light with an anodized shelf or with special treatment with kapton or thick thermal epoxy a DTP will work. I think it’s still better than the dielectric being right under the tiny thermal pad.

Too bad, makes it useless for anything I would want to use it for. Oh well, the hunt for a good high output 90cri 3535 LED continues.

Mine shipped, should get them by the weekend. Sounds like some difficulties - standard centering rings won't fit and standard MCPCB's won't fit, plus the ground problem Facepalm . I'll see if they will fit under 3535 optics, if so, might try an a multi-LED light like the MF01 Mini.

Just to be clear, the comments about 3737 and a non-neutral thermal pad should be in reference to the HHL532.TK (“Black Flat S”). So not too unlike the original Black Flat.

The Luxeon HL2X, on the other hand, is supposed to be a standard 3535 footprint that’s compatible with our existing 3535 stuff.
