I'm enjoying this man speaking

They are a manufacturer ... not a lighting company ...

Dedolight has had these available for years… Godox copied the concept

@@cagf2013 aight.

@@cagf2013 collimated lights existed long before dedolight. used in stage production for like 100 years.

Actually the inverse square law is a law of physics that applies to any light, but the rule of 1/4 of the intensity at twice the distance begins to be achieved, once the distance is larger than five times the diagonal or radius of the light source, but beyond that distance, no matter if the light source is a 12x12 diffusion frame, the law is met.

I was thinking the same thing. Let us know your results and how you achieved it. Assuming it’s possible

Thank you for explaining it in 3 simple words.

WOW U R SOOOOOO SMART

they try to make it sound like a scientific breakthrough but its just a simple collimated light.

There are optional bags/cases designed for transport of the Eflect reflectors in different sizes. Information is below: DEFPB is for the 20x20 reflectors DEFPL for 45x45 reflectors DEFPXL for 80x80 reflectors For more details contact: [email protected]

The presenter “misspoke”. The exposure remains contant not because of the inverse square law but because the inverse square law does NOT apply here; it only applies to light that radiates freely away from a point source. It does not apply to “parallel” or collimated light, focused light or light that is otherwise modified with intensifying reflectors or blocked by grids (occlusion effect). That’s the entire premise of this system= inverse square law does not apply to this light source. To be clear… the magic here has to do with that amazing light source with the special lens on it - and not the reflectors used. If you don’t have that or similar light then this trick with these reflectors will not work.

​@@VectorClassics the light from a "normal" source like a light bulb, or a strobe, or a COB will radiate away from the source as an ever expanding sphere. The further you are from this source the less light density there will be from your perspective. If you double your distance from this source then you will perceive 1/4 the intensity of light from where you stand. That's the inverse square law. It is because the light is an expanding sphere as you move away from its source. But with tools like a PERFECT mirrored parabola and with a light source placed in the "focusing position", or with "special" lenses (like in this video) you can *collimate* the light rays to project PARALLEL to each other as the rays move away from the source; and not in an expanding radial way.... This is what is being used in this video. Again, it should be emphasized, that the magic in this video is because of the fancy light they are using and NOT the $$$$ reflectors (the tittle is a little ... deceiving). Note: with "normal light" if you cast a shadow on the wall with your hand; the shadow will be crisp close to the wall and become larger and fuzzy as you move your hand away from the wall and towards the light source. This does not occur with perfectly collimated light; shadows are crisp irrespective of distance...there is NO fall off .... the rays are parallel. You can APPROXIMATE this effect by using a normal radial light source placed VERY far away. From your perspective those rays will seem parallel; that's the case for the sun. So, you can reproduce this video by using sunlight and reflectors. You can try this with the aluminized side of insulation foam boards you get from Home Depot; you can easily cut them to the size you want. As for using GRIDS over your lights or strobes... well that's a more complicated discussion and has to do with a principal called OCCLUSION; and this principle can also help you prevent the light fall off you would expect from the inverse square law....
