OK to keep up I started to update the initial interst list, initial,not final we understand, yet having all those people on it now (wauw 2 already and I was very strict only those who wrote “interested or I’m in) helps a great dal in finding a manufacturer.

hmm a battery operated penetrator? somehow this doesnt sound right Big Smile

Very cool all those names, we need a name and the basic way we want it (plunger, aluminium box or maybe something else out of the box Big Smile ) before we can go into more details on specs and find a manufacturer to actually build it, rest assure we are talking about options here, but having the three things going we are building now (basic form, name and people interested) are a great start

OK, let’s be honest here.

There are lots of lights with big output and decent throw (mostly XHP70 lights, some XHP50) already.
There are just a few light with really impressive throw and most of them are quite expensive (i.e. Thrunite TN42 or big Nitecore lights).

What I (so just my 2 cents) would be looking for is an affordable thrower, that outthrows the TN42. And by a fair margin.
That leaves only a few options for the emitter:

XP-L HI – estimated 1Mcd and 1400 lumens (not that much more then the TN42 but still decent)
XP G2 (which ever version, dedomed or sliced) – in the 1,2 – 1.4Mcd range and 900 lumens output (estimates)
Oslon Black Flat – Probably same range as XP G2, maybe a bit higher, but factury flat dome so guaranteed good colour rendition.
—> In the German forum I read this Led has been tested to procude 230cd per square mm, at just 3,5A. I really like those numbers because just two cells would suffice to have this led perform at peak.

The XP G2 and Oslon version would mean the light will produc a pencil beam but with throw well above and beyond 1Mcd you would be able to light things up at huge distances and the pencil beam would be quite sufficient so……..yes, please.

Performance fiures like that and no need for more then two cells would also mean the light could be significant smaller and lighter (remember, the Oslon needs only 3,5A) then a XHP35 HI version and that’s not bad either.
In essence, it would be a huge reflector with only a smll space needed for two cells, electronics and switch(es).
We then even could go for the design that Djozz already posted, an extremely compact build.

What are your ideas on this?

Oh yeah and I copy pasted the specs of the Q8, removed things not for this and well time to fill the gaps later if we have a name and basic form Wink

Hello!


Fellows, thinking in putting some bucks in a bigass reflector?


Did anyone dared to try a triple lens setup before?


This is my idea (v2):



  1. Stage one. Pre-collimator: a narrow angle TIR.

  2. Stage two. A convex/plano-convex lens, converging the beam to some point up front: 

  3. Stage three. A concave/plano-concave lens gives us our final result. Check the following pic borrowed from Lens (optics) at wikipedia.

There is a German modder-constructor,who makes lights with collimator lenses,at over 600000cd,but they are aspherics.You can see one of these lights,in CPF.
But they are pretty expensive.

Hi! Smile


Updated my previous idea on #63. In fact, I know think it may be the perfect recipe for incredible performance zoomies. Of course I may be wrong, yet check it out!


 


Über-cheers Party

Yes several well focussed lenses would make a very interesting light for sure.
This is about reflector based throw.
A wide reflector to get the throw.

Also a zoomie with two lenses and now even three, wow, this needs a real good manufacturer that is very actively working with us and can deliver extreme build precision
Let’s see how the Q8, possible future Q4 and this giga thrower (maybe a manufacturer feels compelled to step in seeing this thread) pan out first to see how far we can come with projects relatively easy (yet challenging in itself Wink ) compared to three or double lensed zoomies.


There is a Chinese light with well focussed lenses giving a circular spot without spill.I’ll find a video to see.

I made a simple dedomed XM-L2 + 35cm fresnel lens thrower that does more than 5 million cd (it is a fun device), costs were 50 dollar in parts mainly because the fresnel lens (a cheap plastic device that was sold for ‘solar cooking’) was bought expensive on ebay, a cheaper source would bring that build back to less than $30.

The point is that achieving the 1 Mcd is easy, it is not rocket science neither is it expensive, but doing 1+ Mcd in an attractive convenient package that is as compact and lightweight as possible is the challenge. The fresnel lens thing is a big ugly wooden box, we do not want that in this project.

Well for me (and it seems not picked up by any1 Sad ) this would be the light Old Lumens wrote about he wanted to see made.
He said:
Big reflector
Long srk style tube for 2*4 cells

The 120mm is much bigger then the 86mm he used in a build

This is where 4S2P comes from
And because of the massive heat sinking XHP could be driven hard
And well pencil beam, I’d like marker beam (you know sharpies being thicker then pencils Wink )

Also kicking it back in I’d like to round up the sale price to the next x0 or x5 to get at least $5 so $5-$10 per light sold for Justin and Valerie.

A smaller lens based light would be another project (shame MEM zoned out) and yeah would like to see it and even do it but not until the Q8 is in the hands of all that want one and this giga thrower is at the stage the Q8 is in right now. So if people want that faster I’d day, go for it and put me on the interest list Wink

Then we have two extreme directions in this discussion:

1) The ‘OL way’: big reflector big output led (think XHP70), with consequently a fair number of batteries and large capacity heatsinking
The OL way is heavy and will not have massive throw, you will stay well under 1 Mcd. But the big bright hotspot will be very impressive.

2) The maximum throw way: big reflector small die led (think XP-L HI), can be driven with two or even one battery, heatsinking is very modest.
This can be made very compact, the size is the reflector and not much more, and be featherweight. The throw with a 120mm reflector can be up to 1.5 Mcd. It is an extreme pencil beam!

And then there is everything in between…

BLF LS (Light Saber) or
BLF TM (Throw Max)?

Great project!

Yes PLEASE!!!! Big SmileBig SmileBig Smile

Depending on pricing, at least one and if possible one as host (I would one with XP-L HI IF over 1Mcd – but I still would want one with Oslon Black Flat for max throw, minimal usabilty and max fun)

Man, we don’t want the flashlight to start screwing us after we buy it SadSilly

Probably will if made by Astrolux

I really don’t think so. Nobody would pick up a chunk of solid black metal with a seriously big polished reflector on the end and associate it with some cheap yellow plastic “lantern”. And if they do then I don’t value their opinion very much.

Yes please! This is what I’m hoping for out of this project. Dedomed XP-G2 lights are really impressive on the meter. I know; I’ve built a few myself. They’re not very useful though. I want a super-thrower that’s actually got a useful beam at a distance and that requires just a bit more “width” and overall output than a 900 lm, 1 Mcd XP-G2 would be doing.

That’s just my opinion though.

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. Big Smile

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.
