On and off: To turn on the flashlight, we must press the digital switch for half a second, and repeat the operation if we want to turn off the flashlight.
Changing modes: With the flashlight on, simply click on the digital switch to change modes, alternating between the three intensities in ascending order: L-> M-> H
Memory: The K18 features mode memory function. This is remembering the last mode we used prior to its shutdown, and turns on it on its next power up. The memory is maintained even if, when the flashlight is off, we remove the battery.
Strobe Mode: Like other small AAA flashlights, we have a hidden stroboscopic mode, which we can access if we make a quick double click with the flashlight on.
Lock-out: As I mentioned, the new K18 v2017 can be electronically locked to prevent accidental activation. Simply make a double click from the off to lock and unlock it. Of course, we can continue blocking the K18 v2017 by a slight unscrewing of his head.
Low voltage warning: When using a 10440 the new K18 v2017 will warn us when the battery voltage is too low, going to low mode and performing a triple blink every approximately 5 seconds.
^ thanks for the UI.
Hmm, if I read this well it seems there is no option to avoid memory and go directly to the lowest mode.
(I often want low without getting blinded first and with my memory it is best to avoid it)
Hmm . . . ran across this light in the KD thread. I’d be interested if it did NOT have memory (or simply a way to force it on in low level first) and had a NW option (or at least knew it was an easy emitter swap).
I like just 3 modes, length is critical to me (18650 lights are on the border of pocketable), and I can replace leds myself. So that makes the S20 more interesting to me than the SP32A. Critical as well is direct access to low mode from off, that still has to be confirmed.
Wow, sounds like you (djozz) and I have similar taste in EDC’s - direct access to low, no memory, LED swappable to our own choice, simple 3 (or maybe 4) modes, as short as possible - just add deep pocket clip availability to that list for me. I know it’s anathema, but I’m actually not carrying an EDC much anymore because I need to find something shorter than doesn’t bother me in my pocket. Phones keep getting larger which means more of a problem carrying my EDC light. I started trying to put the light in my rear pocket, but that’s not always comfortable either. I might try going to a belt clip/pouch.
I’m always looking for the shortest 18650 light, that’s why I’m subscribed to this thread.
I already have the SP32A and it’s a great light but it’s long…
…However… the main reason I got the SP32A is because it legos with the Convoy / Jaxman 18350 & 18500 tubes:
106.7mm with the 18500
89.3mm with the 18350
So it’s a real gem with the shorty tubes.
.
So for this Ultratac I agree with you djozz, 3-mode is fine and I will also swap the LED, but I also need to know the UI.
One thing I would miss (if it doesn’t have) is direct access to the highest mode.
BLF A6 and Zanflare F1 are supposed to be 1200 lumens (Turbo). Turns out SP32A also gives out only 1200 lumens instead of the listed 1500 lumens, according to 2 reports. So my question becomes moot.
Yeah, I though 1500lm sounded a little high for what I’m seeing, but 1200lm is quite bright. I’ve got to get a light meter, at least to do basic comparisons.
I wished mode memory was never invented If I can not even remember the important things in life, why on earth should I know in what mode my flashlight was last time I switched it off?
