Produces 1431 mw/cm2 at 6ö away Increases collagen, skin elasticity, relieves pain, speeds healing, and more No UV to block, Teflon, fluorinated fumes, mercury vapor, toxic substances, and far-infrared This light therapy bulb is designed for near-infrared heat lamp therapy. Healing infrared light in the red and near-infrared wavelengths associated with pain relief, increased circulation, faster recovery times, collagen production, rejuvenation and renewal, and peaks at 850nm. At 4 inchesÆ distance, it emits 1,431 Mw/Cm2. This bulb is an excellent choice for pain, regeneration, and rejuvenation. Users say they get fast relief from light therapy and some in as little as one use. In just 15-20 minutes a few times a week, the therapeutic heat from near-infrared light reduces wrinkles, increases collagen and elasticity, provides relief, speeds healing, and more. Unlike bulbs that require no UV-blocking (Because they produce no ultraviolet rays), contain no mercury or Teflon, do not off-gas toxic fluorinated fumes, and are free of heavy metals and other toxic substances.
