See Red & Feel Near-Infrared
Re: Is the GE heat lamp red or infrared?
Both, and here’s how you can easily tell the difference.
It you can SEE the color red across the room, it’s a red light.
Red light is visible radiation, approximately 620 to 740 nanometers, depending on your eyesight.
If you can FEEL the heat radiating from the bulb, it’s near-infrared (NIR) radiation.
NIR spans from 700 to 1400 nanometers, so obviously some folks can “see” infrared radiation.
Visible red light has more healing power than NIR despite NIR’s greater “photonic energy penetration.”
Don’t let those marketing phrases mislead you.
The shorter wavelengths (around 650 nm) are more readily absorbed by blood, and the longer wavelengths (around 1350) by water.
Obviously, the farther away you are from the bulb, the more visible red you absorb.
The closer you get, the more invisible red you absorb.
Most “experts” advise staying at least 18 inches away from the bulb and keeping your eyes closed.
NASA and the U.S. military have experimented with (and may still be using) red light therapy devices because of the following benefits …
According to Ray Peat …
“Subnormal temperatures cause a shift from phagocytosis to inflammation. Light, especially the red light which penetrates easily into tissues, activates the formation of new cells as well as their differentiation. It affects energy production, increasing the formation of mitochondria, and the activity of the DNA methyltransferase enzymes. Red light accelerates wound healing, and improves the quality of the scar, reducing the amount of fibrosis.”
