I started looking for the best pocketable flashlight with good throw. Ideally jeans pocket (like a D4), not jacket pocket (like a C8).
Following the idea from Agro's thread The hottest hot rod, I started recording some flashlight data to work out which one was best. Agro measured hotness in (lm/cm³) but I'm measuring throwyness in m/cm³. I've gone for meters throw, rather than kcd as its a linear scale.
These are the top ones I've found so far. No surprises that Vinh's modded lights dominate the top of the list.
EagTac D3Cvn – 16.1 m/cm³
Lumintop TOOLvn AA – 10.6 m/cm³
Acebeam TK16 – 9.7 m/cm³
Emisar KR1 shorty – 8.6 m/cm³
Acebeam W10 – 8.3 m/cm³
I've added a fuller list and comparison to my blog if you're interested but I'm keen to find out if anyone knows of any other lights that might make the top 5. Feel free to update the spreadsheet.
After putting this together, I think the most usable pocket thrower would be a FW1A that's modded with an Osram W1 or W2. Or, even better would be a side-switch EDC18 or D4 with a single W1 or W2.
What about the S2+ with an SST20 and SMO reflector with an 18350 body to make it pocket carry? That’s about 18US total. I got the one he sells with biscotti and while I don’t have any true throwers to compare against myself, it does seem like it would do well for that need. Not so tight that it’s useless close up, too.
I explained in my blog post a bit more about why I chose cylinders but that does make it more subjective. Feel free to add extra columns to the spreadsheet to work out a more accurate volume as well - maybe assuming they're a conical frustrum. Even more accurate would be measuring how much water they all displace. I'll happily try that if anyone wants to ship me some lights to test :-).
Vinh lists a Tool AA with a W2, which is second on the list at the moment. I wouldn't be surprised if it's number 1 with a W1.
Here is the one I bought with the SST-20. I got the 5000K tint, x6 driver. The x6 is plenty and will still burn you if you leave it on for 5 minutes at 100. So for long term 100 maybe the x4 would be perfect. If cost is considered in the rankings I think it’s definitely one to consider. The cost it’s at makes it something I would toss in my pocket with keys and whatever without a second thought.

Edit: I don’t have any numbers, but there must be some data out there by now.
It’s a W1, modded by Jared at JC Customs. No idea on the throw but I can tell you it throws much farther than my FW1A with XP-L HD but not much less than my GT Mini with SST40 does. So somewhere between 370m and 684m lol.
When I did the hottest list I did not have any specific use in the head. But it appeared shortly after - for a backup light I tend to have tiny high-output throwers. I’ve been thinking that something FW3A or FW4A with Boost HX and aux LEDs would be about ideal backup for me (but there is still no driver that would allow it without crippling current).
I’ve thought that something that combines throw and output in a single spreadsheet and calculates some sensible performance indicators would be useful.
It’s interesting to see you focusing on the other axis.
