I did some testing of this LED in a supfire L6 (26650 light with C8 head). I purchased the LMZ7-QW57 (3V 5700K) emitter from digi-key. I reflowed on a 20mm Tpad XP footprint MCPCB (I got it on the first try :sunglasses: ). With a fully charged 30Q I measured 11.7A by measuring the voltage across a 10mOhm shunt in place of the tailcap (this cell is old so the current might be higher with a new cell).
The results are a bit disappointing. I measured 69Kcd at 6.78m (with smooth reflector, reading taken at point with highest lux), and less than 2400 lumens OTF (ceiling bounce test).
A XHP-50 4500K 90CRI de-domed will do 2000 otf lumens at 6V and 5A (10A for the Luxeon 3V). So in this regard it’s actually quite similar. This shouldn’t come as a suprise as the Luxeon M and MZ are also from 2015. They aren’t new.
I am wondering WHO will be the first lunatic to put 3 LMZ7-QW65/QW57s under 10507 with VTC5A and witness quickest step down/throw out of hand/deflow/melt optics in history :partying_face:
EDIT: I forgot about poor little omten 1288 :weary:
Well about FETed switch I am not feeling a need for one. That would be making a whole built “sensible and safe” which by all means it is not. For the sake of care and longevity for sure but I would love to see omten in action :innocent: I am wondering the same about hole, especially with potential one inside of trousers pocket
I Agree with this one although I am highly concerned that if I decide to build one with S2+ in a month or so Lumileds will maybe release HiCRI Vs and then I will regret?
Carclo stated efficiency of 92% for 10507 with MZs.
Yes, that’s actually just what I did after posting :person_facepalming:
They haven’t tested the Luxeon V yet, though. I know it wont be good but actual numbers and beamshots are still a nice thing.
MZ would be brighter of course at any current, and Vf is crazy low,CC regulation would be maintained ~100% of time even at high mode, I'm just not sure how well it would work with small optics, total die size is bigger than tir entrance holes. Since I got 20mm mosDTP boards,I will build M1 with 5000K 80CRI MZ, just to see how they look in flashlight, XHP50.2 was total disappointment because of terrible tint/coronas.
I wonder what’s the relation between Luxeon MZ, Luxeon M and Luxeon MX…
Is M the same as MZ, but with a dome and larger package?
If yes, dedoming should bring the same performance at low currents and better at high - due to larger thermal pads.
MX is an upgraded variant of M. Eyeballing photos it seems to have about the same die sizes. And doesn’t look flip chip. And emission profile looks the same too. Is there a chance of it being better than MZ?
