Luxeon MZ 500K ? Did he mean 5000K?

I went back but couldn’t find the original post on it.

Corrected, it's 5700K 90CRI 3V variant, tested by koef3 and maukka (measured CRI Ra=95, and R9=89).

Thanks for correcting.

Compared to Luxeon V 4000K you get higher CRI with the MZ, but you give up considerable output and have to deal with the donut hole, (plus at 5700K it’s more CW than NW)

Is that correct or am I missing something?

(Both are 3v and 4040 footprint)

Yes. You get a “snow white” tint. That’s rare. Also, the Vf is super low.

  • MZ has high CRI and it's cool white (which is quite rare combination),
  • Also Vf is lower - good for long lasting and steady/regulated high mode when used with linear drivers,
  • Max "BLF" current ~15-16 Amps and over 2500lm - currently no other 3V LED can do 2000lm+ with 90+CRI
  • Undomed - same effective LES as 4mm^2 LEDs, which means decent throw even with OP reflectors/frosted optics

Only disadvantage is quad die gap, but because emitter is undomed donut hole can be neutralized easier with OP reflectors/frosted optics compared to some domed multi-die LEDs.

Got my Q8 MCPCB today, very nice quality.

Thank you for making it avaible :+1:

received a LD-A4 driver. I’ve mounted it in a Convoy M2 with a XM-L2 U2 3C, AWG 18 wires and springs bypassed.

Set at 6A CC current and mode spacing is perfect
I’ve measured 0.7/30/164/390/693/1330 modes with a VTC6 cell

Thanks for bringing us your products. I hope I receive soon the MCPCB for the Q8

Interested in 6 MZ 90CRI.

led4power, do you intend to carry Luxeon MX too?

MX is 4x2mm2 die in 7070 size, so not really practical for flashlights; 5050 package like XHP50.2 would be much better, it would be much more interesting because of better tint and 3V drive.

There are many lights that come stock with 7070 LED or get modded with one, so I don’t agree it’s not really practical. Nevertheless I agree that it would be better with a smaller package. But it is what it is. And it is the most powerful 3V LED under $100.
Not a great choice for throwers, but a good flooder LED.

Luxeon MX is basically XP-50(2) in XHP-70(2) package, max. lumens would be ~4000lm when overdriven, most people would find this to low, when they can get 2 times more from XHP-70(2).

Do somebody knows a flashlight host, which is suitable for MOSLED 4XP quad d=20mm , LD-B4 and any of the compatible circular edge Carclo optics together?

I am thinking about to build a flashlight with these components, as they seem to be very tempting, but I would need some additional preparation and help. Thank you in advance for any helpful input :slight_smile:

I built a Convoy M2 quad with those parts and kiriba-ru’s spacer. I like it a lot. Also added one of the lighted switches.

Convoy M2+kiriba-ru’s spacer will be very nice.

Take a look at #65

Thank you very much. That would seem to be a nice host for it. I was just wondering, and now I just take note, but I will schedule that build at some point :slight_smile:

Samsung reel of 351D 4000K 90CRI is coming next week.

Dear Neven,

Is there any chance to get your LD4 driver with e-switch firmware in the near future? I am highly interested to use it in the new Sofirn C8F since this one is only available with tailclicky and side switch. Meanwhile the one without side switch is hard or impossible to get.

Cheers,
Thomas

I'm finally close to an end of designing other stuff (mostly pcbs, large batch of various designs is coming within 2-3 weeks ), which took a lot of time and money, so drivers upgrade is one of the next things on to-do list (I left them last because they require a lot of time for developing).

I think it needs to be 31mm to fit X6 .
