any idea about the centering rings? which ones should be used? I guess it’s okay with the stock ones but with the hole made a little bigger for the new led
any idea about the centering rings? which ones should be used? I guess it’s okay with the stock ones but with the hole made a little bigger for the new led
I used a reamer to make the hole in the stock centering rings bigger, it was not fast going because the tiny rings do not provide much grip while the reamer scrapes the inside. Other centering rings that I have in my parts box do not fit the Q8 reflector hole.
Regarding Luxeon MZ 5700K 90CRI (equivalent to 9080 Nichia CRI rating) interest, I got some more info from one supplier, the only problem is looong lead time of 13weeks. If lead time is 5-6weeks, I would buy one reel, but ~3months of waiting sounds too long for me. When I asked why lead time is so long, they said Lumileds actually runs production "on-demand", one good thing might be "fresh out of the oven" LEDs with higher that typical flux bin as result, we are in 2018, last datasheet update for MZ is form November 2015(!).
Planned "group buy" price was 5,97€ per piece (that's Mouser's price for 50+ pcs when you add typ. EU VAT of 20%). Regular price will be ~7,50€.
Is there still an interest in this LED with lead time of (up to ) 13 weeks?
In the meantime, I will have 32mm PCBs compatible with 3x and 4x CUTE optics for Eagle Eye X6 in 3535 and 4040 footprint.
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)
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.
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
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
Larger MCU has plenty of memory, e-switch firmware can definitely fit, I only have to write it:)
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.
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).
They will be 31.4mm in diameter, so they should fit X6, there is small possibility they will not fit on some hosts because of production tolerances, but in that case there is maybe ~0.1mm material to sand down, and that should be very easy because PCBs have 5.5mm central holes, so you can use battery drill in combination with M5 screw+some washers to quickly sand it down.

Thank you!!
I’ve ordered the mcpcb with the leds
Got your drivers today.
Thanks

Yes, I am interested in 3-4 plus PCB.

Portable Thrower Comparison
Yep,still interested.Busy summer starting,13 weeks is fine by me.
Interested in the MZ 90CRI for Q8 Board.
I would be interested in several Luxeon MZ 500K 90CRI and looking forward to the 32mm PCBs.
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).
led4power.com
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.

Got my Q8 MCPCB today, very nice quality.
Thank you for making it avaible
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?

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
Sorry for my poor english.
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

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