GB interest list for Luxeon MZ 3V 5700K 90CRI (9080 Nichia rating)

Commercial Sellers' Spot

I decide to make separate topic for LMZ9-QW57 MZ LED interest list, so please post the number of LEDs you'd like to buy when/if they become available.

Luxeon MZ LED is 4.0x4.2mm domeless LED with 4x 2mm^2 die surface area, and what makes it unique is that there is 3V variant, unlike any other multidie LED.

Also 5700K 90CRI version is quite unique too, it's quite rare to have high CCT and high CRI available.

5700K 90CRI version is capable of ~1500-1600lm at 6Amps, and around 2800-2900lm at ~16Amps, with very low Vf, lower than any other 3V LED - great for long,steady high mode with linear (and buck) drivers.

For example, with 6A LD-B4 driver.MZ LED and Sanyo 3500mAh GA battery high mode will be regulated until battery voltage drops to ~3.2V, which means during 85% of battery discharge, this is as good as having average boost driver and 6V LED @3Amp, efficiency would be also similar, around 88%.

MZ measured by Koef3 here:

One important note: Koef3 measured output with LED on XP noctigon board, there is possibility that output at high currents could be few % better on proper MCPCB with correct pad sizes.

Maukka tested this LED too, and results are pretty impressive, R9 CRI is 89, Ra is 95, overall tint quality is very nice:

To conclude, MZ LED is highest power 90CRI 3V LED available on the market.

Its only disadvantage is multi-die separation, so there will be some "donut" hole if it's used with smooth reflectors or narrow spot optics.

OP reflectors and frosted/medium spot optics can fix that relatively easily, since gap is smaller than on XHP50/XHP70.

LED is domeless, which is good for small lights because throw would be still decent, effective LES is similar to 4mm2 domed LEDs like CREE XM-L2,XP-L etc.

Bad news is that most distributors don't have full reel in stock,and if I want to order one reel, I have to wait for up to 12weeks until LEDs are produced.

Good news: MZ leds available form Mouser,Digikey,etc. can be quite old, MZ LED is released in 2015, so flux bin appear to be around typ. bin; little birdie told me freshly produced LMZ9-QW57 reels have 20% chance to be Q flux bin (780-840lm at 85C), and 80% chance to be R flux bin (840-900lm at 85C) so there is a good chance reel will be R bin, which would be 1 or 2 bins higher than available LMZ9-QW57 LEDs.

Currently I have few boards (MZ footprint of is compatible with Luxeon V) for MZ LED, 16mm DTP, 20mm mosDTP, triple 20mm mosX, quad 20mm mosX, 38x2mm BLF Q8 DTP.

Soon I will have 31.5mm mosX2 triple and quad MCPCB for CUTE-3/4 optics, quad for ANGIE optics - all good for EE X6 host, and 7x for ANNA optics.

GB price is: 5,97€ per piece,

After ~2 weeks I will close this interest list, and after that regular price will be 7,47€ when/if I got reel and put LEDs on my web shop.

Those who are on interest list will receive coupon(s) for my store to reduce price from 7,47€ to 5,97€ per piece (if GB happens) for MZ LED products.

Interest list:

NOTE: you only need to specify number of LEDs you are interested in, other details like would you like it as bare emitter,on xx mm MCPCB...etc is not important right now, you will receive coupon code(s) for my store for exact number of LEDs you mentioned here in topic, and when/if LEDs become available, you can use those coupons on MZ related products. Of course I will offer them on all compatible MCPCBs I have/will have.

I’d be interested in 2, if I can combine shipping with some other parts from your store.

I’m interested if I can get them on mcpcb…

Hello,

i need 5 LED, soldered on 1pcs 20mm Triple 20mm mosX and 2 on Single 20mm mosDTP

Thanks, Joachim

Any plans on selling Luxeon V in 5700k in the future?

Thanks!

I forgot about BLF Q8 4040/5050 DTP pcb, it also can be used for quad MZ build, added to PCB compatibility list in OP.

11

Put me down for 4 please.

12

Ill take 3

13

Put me down for 4, thanks.

14

I’m in for 6, thanks

15

5700K is currently only available in full reels, so it depends on interest.

5 for me

Sorry, can you take me off the list? I was going to put these leds in my Q8 but decided to go with LH351D instead, so I’ll wait until you have those in stock.
