[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

I am in ……

4 or 8 batteries are fine with me…. Just push it.

Regards

I’m in for at least one BLF Mcd

That is indeed a very nice design thijsco19

O yeah, I`m in.

Name, BLF Raptor

Name: BLF Type R or Type “”

Maybe some of us want a laser like beam!

+ on BLF BFL :slight_smile:

BT (BLF Thrower)

BLF Penetrator

It is going to penetrate the darkness after all.

I’m not fussed on the handled box style, seen too many cheap plastic efforts like that which have scarred me for life…

It will not look like the plastic lights and will not feel like it (because it is aluminium). But perhaps this design, however good I think it is in form and function, (undeserved!) evokes too much association with cheap stuff to be viable :frowning:

Djozz idea would make a nice change to the traditional design, anyway count me in for 1 for sure

Name: BLF .50

Regards

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

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 :smiley:

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 :smiley: ) 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:

What about, The Millerator?

or the BLF M1 for short

I like it

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.

I like small!

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.
