Not quite portable then.. Big Smile

It will actually be pretty flat, so the overall volume shouldn’t be much bigger than my previous builds.
As long as it fits in my backpack, can be carried in one hand, and runs on batteries for a long time I consider it ‘portable’ Smile
Obviously not a typical flashlight form factor, or EDC size, but it should still classify as a flashlight by definition.

Honestly your and djozz’s fresnel builds also fit the description so that’s why they’re on this list Big Smile

Although I do personally prefer calling lights this size “searchlights” instead of “flashlights”.

I posted a video, finally with a decent camera you can see something that isn’t just pitch black Silly
Heavy fog at night, visibility less than 100m so the beam doesn’t go very far, but it’s very visible and the people on the street were stopping to take pictures too Smile

That torch is insane as the guy that built it. Smile
In Australia they would probably lock you up for shining your light around like that. Facepalm

Thanks!
Sad Gotta be careful!
During the summer where I was doing some other pics of this light there was a police officer watching me.
Didn’t say anything though, but probably would have if I had been shining it at people/buildings.

You’re right, about the same size as one of those big handheld spotlights, just longer and thinner Silly
Easily fits in a backpack though.

Brilliant thrower… Enderman i have bought the same lens which you used in light canon 1.. But it is not focusing the light projecting too much aberrations…instead i have used small Collimator lens 23mm which concentrates the light onto the second biconvex lens… By this time the biconvex lens is thin and of longer FL… I am unable to buy the optolife lenses which you used in optofire… But by this technique i have confirmed 859 meters… This two lenses technique is good and what if i use thick biconvex lens of 26mm same thickness which you used in optofire?.. Plz help..
