Thank you for the specific compliment, Im glad the button pressure info is helpful.
I check battery voltage by clicking 3 times from Off, in Advanced mode… The main LED then flashes out the voltage… repeatedly, until the button is pressed again. Very convenient, and suprisingly accurate (within 0.1V) compared to my DMM.
Thank you for that background info.
I find the built in charging works very well, and switches from Red to Green, when charging stops. I charge at my desk, so I can unplug the charge cord soon after charging finishes.
I suspect some people will want to charge unattended overnight. I do not recommend that. The battery is not the same kind as in our phones. I still only charge LiIon while Im present, never overnight while Im sleeping.
built in charger trivia:
The SC21 Pro can be turned on while plugged into the charge cable, even without a battery inside.
Both need the same CC/CV charging system and rely on the charging controller to stop charging once finished. Even most cheap charging controllers will terminate correctly.
It’s the others that don’t fall in the ‘most’ category that I’m worried about Although I’m not really too worried about Sofirn charging circuitry. There’s WAY worse out there.
Thank you very much for the several replies and clarification
I was thinking about getting a SC21 but I guess I really won’t go that way.
The lower levels of the SP10 are better and even not having built-in charging, I can solve that with the Olight charger in case I want to use Li-Ion only.
How is pwm on this light? I read a zeroair review which said the pwm was horrible. I know jonslider is not a fan of pwm , so I was surprised to not see a mention of it here.
unfortunately, zeroair does not post the frequency of the PWM, so I dont know how to use his data
fwiw, all anduril lights use PWM, but mostly at a very high speed that is not visible to human eyes
I do not see flicker in actual use. I dont think it would be any different than your experience w other anduril lights…
just checked a stock SP10 Pro (dont have an SC21 Pro on hand) on the lowest mode, in a dark room waving the light held in my hand… I do not see any PWM dots, my iPhone does not either:
.
imo the SC21 Pro is a great little light, I dont hesitate to recommend it.
I like that I can locate the straight sided button by feel, plus I like the leds in the button, makes it easy to find the light on my nightstand.
if you like tailmagnets, it has that too, and if you want a total one stop shop package, the SC21 Pro comes complete with USB C charging built in… and the clip is nice and deep carry. The only downside is the clip is too tight to fit a baseball cap, but the Longer Olight S Bend clips fit the light too.
Thanks for the prompt response, I imagined it wouldn’t take long to hear from you on this topic. I found all of your response helpful, as was the original review.
I’m currently traveling and can’t see all the pwm pictures easily. but the couple I did look at have a period of roughly 50 microseconds. This translates to a pwm frequency of 20 kHz. For some reason I was thinking that in general anduril lights didn’t use pwm. But as I pondered this more I realized the controller chips generally only have digital output, so pwm would be the result. Glad in this case it’s not visible.
BTW, I have a SC21 pro incoming and am looking forward to comparing it to my S1R. Still waiting also for the RRT-01, maybe it will be there when I return home
safe travels
from my limited reading, over 3kHz is not considered to be “biologically active”
malkoff uses PWM of 312Hz and told me “most people dont notice it”. Hds has PWM about 450Hz, again, almost no one mentions seeing it….
so though I remain skeptical about the effect of LED lights circuit frequency, used for long term ambient lighting… (I say the same about zebralights btw), it seems that Oscillators are part of the package, if I want to play in the LED lighting pool…
fwiw, my beloved RRT-01 can also flicker visibly at lowest modes, and still not show PWM dots when waving… Ive come to accept fluctuations as unavoidable in LED lighting.
a couple of considerations about SC21 Pro
it comes w Anduril 1, not Anduril 2, it can be reflashed, which I find challenging, but effective
2. I like the Wurkkos TS10 better than the SC21 Pro and SP10 Pro. For my personal urban EDC preferences.
3. SC21 Pro has a more throwy, focused hotspot and smooth transition in the spill than the SP10 Pro. The TS10 is more floody, as is expected from a triple.
4. Only the TS10 has choice of Aux light color. On SC21 Pro, the button LEDs are only available in green. (changes to red while charging, very effective). No aux, no button light on SP10 Pro, button is hard to find by touch.
Yeah, I realized that, I have parts and pieces to reflash the Attiny chip (16, or 25, or?) in the D4 and LT1, hoping with some mechanical tweaks it would work with the SC21 as well. Or for starters might just go with Anduril 1.
Hmm, I’ve not been paying much attention to flashlights for awhile, didn’t know about the TS10. Don’t really need in light charging, like aux LEDs, but probably will hold off for now, or at least until I see how things on the way work out.
