A simple sheet of water (e.g. some pyrex pan filled with water) will block the infrared from an incandescent, and allow you to keep it much closer to the body.I feel its important to stress again the importance of not mixing light bulb/heat lamp therapy with LED photobiomodulation.
Incandescent light bulbs are great for indoor lighting, and using bright incandescent light bulbs near the body will warm you up and offer some benefits, but it is still mostly infrared light. Incandescent light bulbs emit 10% visible light and 90% infrared light, as long as the lights/heat lamp are kept 3-4 feet from the body they are safe, they offer thermal heat and the longer wavelengths of the infrared spectrum are absorb readily by water so your tissue will warm up some, this is exactly why i feel infrared wavelengths should not be used in photobiomodulation where the strong focused LED light is held close to the body.
“A heat lamp is an incandescent light bulb that is used for the principal purpose of creating heat. The spectrum of black body radiation emitted by the lamp is shifted to produce more infrared light. Many heat lamps include a red filter to minimize the amount of visible light emitted. Heat lamps often include an internal reflector.”
In photobiomodulation the shorter wavelengths of orange/red spectrums are not absorbed well by water molecules so they are much more bioactive, the light photons make it in to the cells.
