Directed by The Sacred Egg and produced by Tom Birmingham and Natalie Arnett of Riff Raff Films, [5] it features the band "performing the song in an empty room that slowly fills with water", after which "a horde of bodies burst out of invisible pools on the floor, ceiling and walls ... the room is cast in a deep red light and Thatcher and Kerr ...
Pachystomias is one of three deep-sea fish that can produce red light bioluminescence, along with Aristostomias, Chirostomias, and Malacosteus.In addition to producing blue light via postorbital photophores, Pachystomias also possess suborbital and preorbital cephalic photophores that are capable of producing far-red bioluminescence, with wavelength emissions of over 650 nm.

Particularly intense near-IR light (e.g., from lasers, LEDs or bright daylight with the visible light filtered out) can be detected up to approximately 780 nm, and will be perceived as red light. Intense light sources providing wavelengths as long as 1,050 nm can be seen as a dull red glow, causing some difficulty in near-IR illumination of ...

Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light, ranging from approximately 700 to 5000 nm and "far infrared" is closer to the microwave region of the electromagnetic spectrum , ranging from approximately 25 to ...
Broadband polychromatic light (white light) and LED radiation can only penetrate 0.0017 mm to 5 mm of tissue. [24] For example, research shows that at wavelengths of 450 nm and 650 nm only 1% of the light reaches approximately 1.6 mm and very little reaches 5 mm. [25] [26] Only laser radiation can propagate into deeper tissues.
