I am in.
Is it time for the first poll?
What form will the BLF giga thrower have?
1 plunger
2 reflector and all around in with handle
(Sorry leaving out the lens(es) option that seems totally different project
Plunger and pencil beam. At 500m+, I don’t want any beam width lighting everything up, just enough to light up a 3m wide area, if that is even possible. 
I am In depending on price.
Just a note, when I say “width” I’m not talking about spill. I don’t want spill either. Spill is the death of a thrower because it messes up your night vision too much.
Maybe a bad example, but here’s what a de-domed XP-G2 looks like in a much smaller host (XinTD C8):
This one “only” does 158k cd, or about 795m throw. In a bigger reflector that would be even tighter with even less spill. Which is awesome to see, but not very useful in my opinion. I’d rather have the thicker beam of a larger emitter assuming the reflector can be done right so as to avoid spill.

Agree, but the question is: what do you want to light up at what distances.
Maybe some of the math buffs in this forum could give us a rough estimate of spot diameter, depending on led used, based on the 120 mm reflector?

Amazing!
The trouble is, section 2 we have 0 lights. Section 1 we have millions of lights, and in between another million lights. The market gap for 2 is huge.
Please add me to the interested list.
I see in the OP mentioned: glass lens, while a plastic lens may be a better idea considering the 120mm diameter, light transmittance is the same, sometimes even better than glass, and the light will be much less vulnerable and more lightweight.
I’m not sure about plastic being not as flat as glass: I did not notice it yet, but that may affect the beam and throw somewhat.
me too. sounds fun
I am interested depending on price
BLF Trébuchet
Price and throw should be the main objectives. I have no idea which one is cheaper, but I presume the plastic is. Novelty materials should not be primary goal in my honest opinion.
Count me in please.
My name proposition would be BLF UT (Ultra Thrower).
Best regards Tom
My input:
The host design from djozz looks very innovative and would be very nice (if made of aluminum).
Will the reflector be made of aluminum or plastic?
Plastic reflectors tend to be rather imprecise compared to ones made out of metal. Metal reflectors themselves can have varying precision, but generally they tend to work.
The precision is important if one wants to combine a large reflector with a very small led. This is why reflectors for large searchlights with xenon arc lamps (very, very small point of light in the arc) are so expensive - they are very precise.
If the reflector is made out of plastic I would recommend using a larger LED like a de-domed Luminus SST-90 (P-Bin @ 15A) oder CBT-140 (factory de-domed, very expensive, inefficient, but 4000-6000 lumens from 14mm^2 is very nice). A de-domed Nichia144A series or de-domed Cree XHP-50 would be more modern and efficient (but with donut-hole).
If the reflector is made out of of metal the Cree XHP-35 HI, XP-L HI, de-domed XP-G2 and Osram Black Flat are all nice options. The Osram Black Flat has the absolute highest luminance, is readily available, has a nice tint and doesn’t need to be de-domed. It’s only problem is that it has a very small 1mm^2 DIE, half the size of a de-domed XP-G2.
The XP-G2 would need to be the old version with small DIE in the S2 Bin. This is very hard to find, especially in larger quantities. It might also have an ugly tint after de-doming.
The XHP-35 HI is probably the best compromise for extreme throw and still some lumens.
I would be in for 1 depending on price and if it can make it for Christmas 2020
I’m in for a box style pencil beam fun toy with no practical use 
I am interested and in for one.
Good luck with the design, looking forward to follow this evolution.
I vote traditional flashlight shape with a 4-cell carrier. So really TN42 shape with a little bit bigger head.
I vote for XP-L HI or XHP35 HI
I vote for a weapon-related name, like “Machete” or “Howitzer” or “Katana” or my favorite: “Gladius”
Count me in as interested. Hey we call it Goliath!
Definitely interested!
