+1 to you too! I want a fully capable light! Something that has the capability of something else priced 3 times more! Maybe design wise it’s ugly but it’s awesomely capable, I will still take it!
What about something entirely different? What about a recoil type of a design using an XPL and a heat pipe and a 60 or 80 mm reflector? That design has a far reaching and intense beam.
1st surface reflectors are a bit spendy about $20 - $22 for 75mm Anchor Optics
Maybe if we bought as a group buy they could make us an enhanced aluminum 1 st surface reflector at a nice price. Some limited production runs are as low as $13.
Well, we do have UF 1504 and 1503 at quite a temting price, an A17DD based 1503 do easy 250k mcds 1504
The one thing that we dont have is a nice 18650 55-60mm reflector based thrower, rifle mountable, light- 250gr tops, kinda pocketable too
That hd2010B will do the trick, ESPECIALY if a host only - engraving free ofc, on ultra, unique, tesla or godsfire…boored of those “something-fire based” flashlights….
Well I was having a chat with Jack via email who seems to be much more open to sending a sample but Celia has taken over all conversations saying she is in charge of this groupbuy so I think we need to look elsewhere.
Agree, keep it small please! There's only big throwers around and there's no reason at all for the performance a good thrower to be big (how much space does a single 18650 and a single led at 5A need at all?). You need the large reflector diameter and the rest can be made very compact and lightweight, even big fins are not needed for the performance, some modest finning is just fine.
“I think what we all want is a single 18650 stl-v6. Do we just need to design it in CAD?”
.
“All” of us?
Sure, I would like to have one of those too, but I also want a BLF - BIG-HEAD THROWER!
Not so Big that you would never use it… Maybe something around 70-90mm Head diameter, using 3 cells in series?
Yes - I think that you would have to design a “stl-v6”in CAD. - Please clue us in
Thanks,

EDIT: You said: “Tom was getting near 250 kcd with xml2-u2, so should be possible to get closer to 300 kcd if you were willing to go xpg2 or xpe2 for a super thrower”
XP-E? - Very true, but that is just the sort of thing that is done, just for fun. - Very small Hot Spot, so better figure in the cost of the Binoculars you are going to need to see anything:) Not a very satisfying beam profile. - Great stuff in a P60 size though, I would imagine.
A larger emitter, “XP-L HI” will do the same thing, with a much larger, more useable Hot Spot
The XP-L Hi or XM-L2 will not do the same thing, they do not have anywhere close to the surface brightness of a XP-E2 at 2.5A, and so will throw considerably less. A XP-G2 comes closer already but will still not equal the XP-E2. If you manage to get the XP-G2 at its maximum brightness (which is not possible with a single Li-ion cell) then it has almost the surface brightness of the XP-E2. The XM-L2 and XP-L will blow their bond wires before the maximum die brightness is reached.
I vote for single cell 26650. I believe its a good trade-off between performance, runtime & size. It also does not give the out of proportion look by putting a huge head on a 18650 tube size e.g. the Eagle Tac Turbo heads - it really just looks funny. Well, my opinion that is…
Should the preference be multi cell, I definitely prefer parallel please 3 or 4 x 18650. This allows for linear DD drivers on the common thrower type 3V LEDs (XM-L / XP-L / XP-G). Buck drivers are ‘complex’, expensive & has possible heat issues when driven hard. Parallel cells are obviously also good for voltage sag compared to single cell setups, but, my preference still is single cell.
Only reason I would go for multiple cells in series is to run XHP-35, that is 4 x 18650, direct driven.
I just want to clarify. Are you saying that XP-E2 at 2.5 amps will throw further in a big thrower head than any of the XP or XM leds @ max amps in single cell setup?
