I have both.
They’re both great lights but IMO they have slightly different uses. I think you have to decide if you like (or need) a dual switch light or not, the SP32A only has a side switch.
The TK18 is a larger light. (slightly longer, thicker and heavier) The SP32A is a more compact size for pocket carry.
If your interest in these is for the ramping UI the main difference is ramping speed, it’s about double on the TK18 (about 3 seconds vs 6-7 seconds)
The mid ramp pause on the SP32A isn’t an issue for me, yes it’s noticable but not a long pause, the whole ramp is only about 3 seconds.
I haven’t done a side by side beam/throw comparison but the TK18 has a bigger reflector that’s OP, and the SP32A’s smaller reflector is SMO.
One final consideration is if you would like to have the option to convert to an 18350 shorty light, the SP32A fits the Convoy/Jaxman 18350 tube and makes a great shorty.
The TK 18 is a better tactical light because of it’s tail switch, which is also a forward switch for momentary on.
If you prefer a dual switch light that’s smaller the Thorfire VG15S is a dual switch light that’s exactly the same size as the SP32A.
Lightbringer and beam0, thanks a lot for your thoughts. I have SP32A so I kind of get some picture for that. It seems promising.
I hope that Thorfire decrease the ramping as beam0 suggested. That would make ramping function more useful to real use.
I’m not sure if it’s alright to be discussing another flashlight SP32A (but it seems similar to the Thorfire TK18 in features).
The SP32A has an older batch and new batch. The older batch (purchased around Feb-Mar 2018 or earlier) had a slow-ramping, around 7-8 seconds.
The new batch (April 2018 onwards?), around 3.5-4 seconds (beam0’s SP32A appears to be from the newer batch, with quicker improved ramping).
As shown in the video below:
My guess is the current Thorfire TK18 is similar to the older SP32A with regards to ramping time… hoping Thorfire will release an updated version with faster ramping next time?
I cancelled my TK18 (flashlight alone) order and bought TK18 kit instead. Has your TK18 order shipped yet?

Bump… I got the kit, it’s a nice light, but still got the light-only as backordered. Just wondering if anyone has any news about when it’ll be available. Nice price, so I’m not inclined to cancel the order or anything. Well, maybe, if there’s an equally nice price for the kit again.

It is taking way too long. Perhaps you want to consider changing your order to complete set instead? Dump the charger and battery on eBay (or local market) later if you don't need them?
