    Well, may be you are right. Just checked Elzetta B343 in a dark room trying to cover roughly 5/6 of its floody lens. Of course, this evaluation precisely +- an elephant, but looks quite usable and not blinding

    I simply don't use small AA flashlights like this for high output tasks, and would rather have the runtime ....

    Very interesting link, but to my opinion there is a basic mistake on the opinions, and it is that everyone speaks about lumen but no one about angle, which is a very important factor. Within the same family of optics (real case), a 10º one will be and will feel to your eyes 4 times brighter than a 40º one. 60 lm with a 10º will be more "blinding" than 200 lm with a 40º one. The 40º is just more comfortable to your eyes, because it can cover greater are and does not create "hot spots" in great contrast with darker areas. From the distance of your head to a book in your hands, a floody lens will cover the whole book, while trying to read with a narrower angle emitter will be a nightmare and really tiring for your eyes.

    This is a really nice looking flashlight. Have you considered making it in raw copper?

    I'm not so sure it is a "mistake" as it is just choosing a different variable to discuss

    There are plenty of other threads discussing beamshape and lux here too ....

    I have made prototypes in brass, titanium and stainless steel. Copper I haven't considered, but once the drawings and tooling are made, there won't be problem in making them from copper. But to be sincere I would like to make them galvanised!

    OK, seriously speaking there are out there a few interesting alloys, based on Niquel, Cr, Mo... that are highly resistant to most chemicals.

    Would be amazing in RAW copper .... NASA Apollo era patina could be easily achieved :-)

    Well, the original was made from brass. And yes, that patina is quite easy to accelerate, I did it on an early sample with ammonia, but I think that the best way to get a patina with personality is to do it with your own use and hands, just takes longer.

    Here you are, for a few hours. Your opinions will be as usual more than welcome. Anyway, is just a "draft"

    I like the video, including narration, but was looking for a little more on the light at the end. Maybe next time?

    Nice video, well done. I like the sound of the radio communication in the background and the interference of the video. It has a good atmosphere and leads towards your flashlight.
    I agree with kaichu dento, some facts about the light, at least some buzzwords or a teaser about the technical data would not be amiss.

    Love the video -- the footage, narration/sounds, and editing. Agree with ideas from other members that some information on specific features of the light would be a good addition.

    Went over and made my contribution...since I'm the first official backer...I will of course receive serial number 00001 or something like that...right? But seriously, I really hope the goal is met! Good Luck!
    I only fear that if something happens to me, my wife will sell all my stuff for what I told her I paid for it.

    Beautifully designed flashlight. I really like its simplicity in design.
