Horizon II Light Therapy Unit
with Dual Infrared and Red Wavelengths
by Hill Therapeutics

Powerful, Effective, Safe and Affordable...

The Horizon II Infrared and Red Light Therapy unit delivers a powerful 800mW of infrared (880nm) and red (660nm) light with 36 infrared super luminous diodes and 7 visible red super luminous diodes. The treatment surface plate is roughly 2" in diameter. A dose of 4 J/cm2 takes a little over 90 seconds. The Horizon probe can be purchased as a plug-in to the new HF54 Hands Free Ultrasound or separate as a portable standalone.

The standalone Horizon was designed to be lightweight, durable and portable. The entire unit weighs 2lbs. 8oz. with the probe handle weighing only 8 ½ oz. This lightweight design eliminates operator fatigue and makes it easy to transport. The standalone power supply plugs into a standard wall receptacle. Hill Laboratories also manufactures an inexpensive rolling cart for $100 or the unit can simply sit on a shelf.

NASA exclusively uses light-emitting diodes (LEDs). “LEDs stimulate the basic energy processes in the mitochondria (energy compartments) of each cell. DNA synthesis in fibroblasts and muscle cells has been quintupled using LED light alone.” *2 “Evidence indicates that cells absorb photons and transform their energy into adenosine triphosphate (ATP), the form of energy that cells utilize. The resulting ATP is then used to power metabolic processes; synthesize DNA, RNA, proteins, enzymes, and other products needed to repair or regenerate cell components; foster mitosis or cell proliferation; and restore homeostasis.” *3

LED vs. Laser (LLLT):
“The light source does not have to be a laser in order to have a therapeutic effect. It just has to be light of the right wavelength." *3


Light Therapy can safely be applied directly over the spinal cord, joint replacements, internal metal, and joint capsules in arthritic conditions. Muscle stimulation and ultrasound are contraindicated in these areas.

Depth of Penetration:
"Measured Spectroscopically, light photons at wavelengths between 630-800 nm travel 23 cm through the surface tissue and muscle." *1
