yep! while doing accupuncture they used red ultraviolet heat lights concentrated on my intestional area, super soothing and helped greatly to reduce the immflamation. It was the part I looked forward to the most!
I've been to spas where they also use red heat lamps of similar style. They also use ultrasonic sound waves with direct contact for blood circulation/stimulation of skin and organs to reduce swelling, etc.
sun light/and artificial sun light are used for depression.
I engage in some modest manipulation of (well, attempts to manipulate) circadian rhythms via blue light blocking (via blocking glasses with orange lenses, f.lux on computer) at night and blue light exposure ("dawn's early light"). I'm not using light bulbs to do this, though. Come wintertime I may get a dawn simulator, which tends to be a panel of lights, but for now actual sunlight suffices.
I also cultivate complete darkness (well, as complete as I can get) to encourage deeper sleep. I like the concept of a lightbulb that emanates complete darkness (I suppose I should call it a "darkbulb"), but obviously, again, I'm using light blocking devices here.
I do wonder (although I'm slipping further off-topic here) what the long-term effect of public health will be on the phase outs of incandescent lighting for general purposes in many countries including the US. It could well be as profound as the introduction of artificial lighting in general (which seems to have shortened average sleep times over time).
Photonic Health is the leader in light therapy products and educational courses.
They have 2 lights that run at the 660 nm (nanometers) that can create bio-stimulation, relax muscles, anti-viral and regulating acupoints.
I highly recommend Photonic Health
