I took a quick picture after organizing veg area and noticed a red halo on the ceiling. It has to be the IR or red LED, just found it interesting. Thouht I'd share it and wonder why they flash up on the ceiling like that.

I don’t think it’s ir as it’s almost invisible to our eye, in fact when we see the light from an ir diode it’s usually the other wavelengths used to create it, it doesn’t even reflect off the tent and just passes through it, we experience ir as heat

The effect is optical, not spectrum or IR related but seems to be little individual diodes “squeezingl their photons through a small opening, projecting” that image on another surface.
Yeah it's really odd, the plot thickens lol...a cable was hanging down covering x amount diodes and I could see it clearly in that projection.

Do you want to guess what light am I using?
Outrageous shot....very f'ing cool ! The red stripes remind me of the black and white movie , " Rumblefish", Coppola I think. I think it was the first movie to have color introduced ( brief moments ) into
a black and white. In this movie , there were a couple of quick hits of a couple of red goldfish amongst all the other black-white fish. .......suitable for framing! That effect really made the scene f'ing pop !

That means some of the reds only are bouncing off the not so shiny floor then,

What's the light? And that's a linear spread!
It's a 240w board, it's shinning a picture of itself through that zipper.

It's not as if the light is sitting behind it, it's at the roof where you'd expect lol
Idk what it means but it's saying something I don't understand.
