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?
I noticed that too about 10 days ago when I found out about this light.
I also find it odd that a company can design and implement a new model, all they way through production and listing it on amazon, but still not have a listing for it on their website. I’ve also noticed this same pattern with one or two other companies, can’t remember which ones ATM.
I came across this ultratac s20 light today on amazon and started searching, it landed me here (my flashlight home). Has anyone purchased this light or have anymore info. I can’t find a review anywhere.
I haven’t, waiting for someone to do a review/impression. It is all about the user interface, if that is good I want one, if not good this flashlight is one of many I will not use and therefore not buy.
Double-click from off: activate or deactivate electronic lockout (will blink once for locked, twice for unlocked).
I forget if the light has mode memory. I think it does.
I think double-click from on activates strobe, but I’d have to double-check that.
Impressions:
Fit and finish is decent. Knurling is a little smoother than I’d like but works ok.
USB cover is recessed and fits well enough it won’t come out accidentally and flop around.
Battery compartment springs are a bit short. My sample did not work with flat tops due to this. Button-tops work fine.
Came with a copper star with some thermal grease underneath. No idea if it’s DTP or not, but copper is a good sign for a budget light.
16mm star - easily swapped out for emitter of your choice. Parts are not glued.
Metal switch button is extremely easy to accidentally depress making lockout necessary. Fortunately double-click for electronic lockout is very easy to do.
Overall a fairly nice light for the price. Not a huge fan of hold for on-off though. I prefer something like D4 or Zebralight interface.
For the Nitenumen C8 I don’t know for sure if it has PWM (Don’t know how to measure that) but I don’t notice any strobing effect. Here’s a reply to someone else asking about PWM in the Nitenumen C8 thread:
Also the UI is not too good (you have go through blinkys to get to off) also it always starts in high, and there’s no memory.
Thanks for posting, I thought the switch was rubber from the photos, good to hear that it’s metal though. (so I can do my switch locating mod)
I’m surprised to hear it’s extremely easy to accidentally turn on, I thought the opposite because in the photos the switch appears to be recessed, plus the long hold to turn on, is it really 1 full second? (user manual shows .5 second).
Also can it be physically locked out by slight unscrew of the tail cap or head?
BTW, according to the user manual (See post #28 above) it does have last mode memory.
