I guess that Panasonic GA is ok if it will not pass 6A mark in DD setup where this emitter starts to loose performance…
I tried this low current cell: LG 18650 BD1 (pink cell unprotected) and since that is 4.35V cell charged to 4.2V it did not passed 5.5A with Osram white so I guess if charged to 4.35V it would not pass 5.8-6A but I don’t have 4.35 charger to test that.
BTW BOOM! Will not happen at 7.2A… Tested with Samsung inr 30Q(real Samsung cell from nkon.nl) … And I really doubt GA can reach 7A mark even with bypasses. Let me check… Yes in my test performance at 7.2A performance drops for cca 20%
Oh yes I forgot that there are better high current cells than Samsung 30Q that could actually reach 8A… Well I would try but I don’t have better than 30Q. If you ordered couple of them than why not?
Maybe you got lemon among lot and better emitter awaits to be build… You never know…
Well the reflow annoyed me more than it should and centering the reflector took me an hour.
Usually destroying is my thing, but not YET here. :innocent:
Perfect reflector centering is PITA. I got best performance when I tossed centering rings and just used eyes and lux meter for centering… That why I prefer zoomies or aspherics.
So”only” 286kcd in that GT mini? Mitkos super budget 10$ thrower(aka supwildfire something) flashlight simply destroys that performance at 430 kcd but yes… Some guys will say pencil beam
I just tried them. In the GT mini I got 219 kcd with it but it need to raise the reflector a bit. Tonight I have no time for that. And putted one in a 9x7135 convoy driver convoy S8. The reflector is a regular S2+ Smo reflector. It has fix 3,15A current and I got 30800 cd. Not bad from a tube light
With dedomed XP-G2 this same light made 22000cd.
In my test at 3.3A it had same performance as the best G2 (xpg2s42b dedomed) on 4.7A current draw. So comparing to other and older classic dedomed G2 emitters it should over perform them even at 3A as you said.
Using the kw cslnm1.tg spec sheet.
The chromacity bin is: ebxD46. Looking at the Osram datasheet and plugging the coordinates into this website,
the CCT is between: 5849k to 6384k.
Less cool than the Black Flat. The warmest tint bin in this series is the fcbB46 that range from 5,3xx to 5,8xx. However, I have the Skylumen Delta with the Black Flat 6500k and the tint is actually very white with no blue and being a WW/NW fan, I find this specific 6500k very acceptable even though I dislike other bluish 6500k lights I’ve seen. Maybe it’s because of the negative DUV makes it appear whiter?
Plugging the coordinates here:
the DUV is between: –0.0044 and –0.0043, which will at least ensure the beam will not be green, maybe it will be a bit on the rosy side. I like the pure white of the black flat. Hopefully this is about the same.
The flux bin is 6N
at 1A: min 315 lm and max 355 lm
Hey, do you mean the gap between the LED PCB and the reflector should be increased? Or should the LED be raised inside/deeper in the reflector?
So is this usually the way to determine if you should raise or lower the LED inside the reflector? If the beam is going thinner, then raise the LED; if it is going wider too quickly, lower the LED?
First question: increase distance between led MCPCB and reflector.
Second: opposite what you written. But you cent raise the led or lower you only can play with reflector by the centering ring thiskness. Or stick tape layers around the led under the centering ring. That is what I have done.
For the new Flat white, Does anyone know what the model number would be for the “perfect” version?
I am thinking about sending it to a manufacture I am working with for a new light but obviously want them to get the best version of the LED if possible.
I did not see a model number break down in the datasheet like some LED’s.
