Thanks for the test Jerommel and the heads up on their site Barkuti!
Letās see if the PkCell and the Lumintop worth a try. It they are nice, why not?
If they are not, Windyfire may be an optionā¦or the Trustfire IMRā¦or the AWT IMRā¦or the On The Road :person_facepalming: :person_facepalming:
Unfortunately the batteries got to me first from AliExpress, even though I ordered the OTR M3 from GearBest at least a good few days before the batteries. Hopefully the M3 will turn up next week.
I know nothing about numbers ( :person_facepalming: ) but from your measurements it seems that for lights like the OTR M3, or an Olight S1R, it wouldnāt be a good battery mainly specially to use the brightest levels, right?
Also, theoretically, it would perform worst than - examples - the AWT IMR , the Windyfire IMR, and the Trustfire IMR, (all tested by HKJ), am I correct?
It will be okay up to 1.5 Amperes or something.
With a linear driver thatās approximately 6 Watts, which is usually around 650 Lumen from an XM-L2 (correct me if iām wrong, anybody)
Yes, probably.
I had to know myself too.
I guess we should wait for a next generation 16340, similar to the Aspire 18350.
Probably just a matter of time.
Thanks again for the explanation Jerommel! :+1:
If I understood correctly, they will run āwellā except in the highest modes (that are above 600lm in the lights I mentioned)!
Hum, getting a āAspire IMR 16340ā would be pretty nice :sunglasses:
I like small lights (16340 sized), and I donāt have more because I want to have them with decent batteries and thatās being hard to get (maybe Iām too picky about that, I admit)!
Sorry fellows but, after observing lots of li-ion cell discharge curves:
When a cell is fully or nearly fully charged and/or nearly discharged the discharge curve slope is higher. Measuring internal resistance when cells are close to full or empty is just wrong.
When a cell is discharged it heats up proportionally to the square of the current flow. This usually means the cell's internal resistance diminishes a little bit.
In every other aspect, li-ion cells' internal resistance is fairly constant.
Hmmā¦ from the ownerās manual of my Opus charger:
I think that however you decide to test, the key is to be consistent and measure all your cells at the same charge/voltage level so that you have apples to apples comparison.
I would say itās best to measure Ri at the average Voltage, which is 3.7 Volts (without load).
This is in the middle of the range the battery is used in most of the times.
Well, since this thread is more or less about the OTR M3, which (probably) has a linear CC driver with maximum current of 2.3 Amperes on āturboā, it should actually first be established how much voltage it needs to push 2.3 Amperes through the XM-L2.
Iām not even sure how much voltage this particular generation of XM-L2 needs to draw 2.3 Amperes.
what are the lumen levels and mode sequence of each light:
Jaxmnve M3
OTR M3
Do both lights have built in over discharge protection, (which means you do not need to use protected cells)
Does anyone have beam shots comparing the Cool White and Neutral white?
Since both are low CRI, the choice of Color temperature should be based on whether you plan to use the light when your brain is white balanced to a Cool White environment, or a Neutral white environment.
Neutral white that is Low CRI does NOT improve Color Rendering, because it outputs more Yellow and less Blue than cool white. However Neutral White Low CRI does NOT produce more Red.
since the OP is talking about wanting the most brightness, Imo he should buy Cool Whiteā¦ (Im not sure which one he ordered after all)
I am very happy with my Keepower IMR Unprotected cells.
But the discharge rate of the cell may not matter IF the M3 modes are Regulatedā¦ Are they?
however, I do not have any Neutral White Low CRI lights myself, so I cannot compare a 5C XM-L2 to a 4000k N219b myself. If you have both, maybe try taking some photos of your hand with them. Try to use daylight white balance for both photos.
here is another example
natural daylight:
Low CRI:
High CRI:
In any case, High CRI is not an option with the M3, you can only choose the color temperature, Cool white or Neutral white
I personally avoid Cool White unless I am using the light during daylight hours, when my brain is white balanced to daylight. But I mostly use my flashlights after dark, so Cool white is not my preferenceā¦
each person has different needsā¦ because they use their lights in different ambient light scenarios
my solution is to buy some of each kind and swap lights depending on the environmentā¦
I think you are right, neutral white low cri does look like it has better red than cool white low cri, not as good as neutral white high CRI, but definitely better than cool white
Cool White:
Neutral White:
the red does look less brown with neutral white, even low CRI, the other colors also look more realistic to me with the Neutral than with the Cool
thanks for helping me learn to be more open minded
since Im a color snob, I agree with you that the two choices of LED for the M3, I would pick the 5C Color Temperature.
Same here, but to me, the light has to be brighter. Cooler CTs are more jarring to the eyes, so even a little light has its own shock-value, but warmer CTs are smoother and less of an assault on the senses, so I kinda āneedā more of it.
also agree, as lights go up in CRI, they also tend to go down in brightness
as lights go down in Color Temperature, even if they donāt go up in CRI, they also tend to go down in brightness
