LED Photobiomodulation as a Modern Clinical and Wellness Tool
Support Patient Care
Expand Care Access
Advance Clinical Practice
Sustain Practice Growth
Photobiomodulation (PBM) is increasingly incorporated into veterinary practice as a non-invasive adjunct modality to support animal comfort, recovery, and overall wellness. As client interest grows in conservative, drug-free care options, many veterinarians are reassessing traditional light-based tools and exploring newer technologies that offer greater flexibility and broader application.
Visum Light is a professional-grade LED photobiomodulation system designed for veterinary clinics, rehabilitation environments, and supervised home care. It combines multiple wavelengths of light with optional sound-based modulation, allowing veterinarians to expand wellness-focused services while maintaining clinical judgment and oversight.
Overview of Veterinary LED Photobiomodulation
LED photobiomodulation uses specific wavelengths of visible and near-infrared light to support normal biological processes, including:
Local circulation and oxygen delivery
Cellular energy metabolism
Tissue response and recovery
Autonomic nervous system regulation
When applied appropriately, LED PBM is non-thermal, drug-free, and well tolerated by most animals, making it suitable for use across species, sizes, and temperaments.
Wavelength and Tissue Penetration
- A common misconception in veterinary medicine is that laser-based photobiomodulation inherently penetrates deeper into tissue than LED-based systems. Current research does not support this assumption.
- Tissue penetration during photobiomodulation is determined primarily by wavelength, tissue optical properties, and delivered energy density. It is not determined by whether the light source is a laser or an LED.
- Near-infrared wavelengths, generally in the range of approximately 800–900 nm, demonstrate the greatest penetration into biological tissue. Both laser and LED devices are capable of emitting light within this range, and when wavelength and dose are comparable, near-infrared LEDs can achieve tissue penetration similar to near-infrared lasers.
- Laser systems concentrate energy into a small focal point, whereas LED arrays distribute light across a broader surface area. For many veterinary applications, particularly those involving musculoskeletal structures, neurologic support, and whole-region comfort, broader coverage may be clinically practical and time-efficient.
Expanded Wavelength Options in Veterinary Care
Many traditional veterinary light therapy tools are limited to one or two wavelengths, typically red and near-infrared. While these wavelengths remain foundational, additional visible wavelengths allow veterinarians to broaden how light is used within wellness and rehabilitation contexts.
Visum Light includes:
- Red light
- Near-infrared (NIR) light
- Blue light
- Green light
- Polychromatic blends including yellow, magenta, turquoise, and white
Different wavelengths interact with tissue and sensory systems in distinct ways. While red and near-infrared wavelengths are commonly used for tissue and recovery support, other visible wavelengths are often incorporated into sessions focused on calming, sensory regulation, stress modulation, and nervous system balance.
Polychromatic blends expose tissue to multiple wavelengths simultaneously, providing broader spectral exposure than monochromatic devices and allowing sessions to be adapted to the animal’s presentation and tolerance.
Sound-Based Frequency Modulation
In addition to wavelength selection, Visum Light includes optional sound-based frequency modulation.
These frequencies are based on observations described by Paul Nogier, who identified specific frequency ranges associated with observable physiological responses. These frequencies are not pharmacologic and do not rely on thermal mechanisms.
In this system, sound-based frequencies modulate the LED output, with light serving as the carrier. In animal wellness contexts, these modulated light signals are commonly incorporated to support autonomic nervous system regulation, relaxation, and stress modulation.
Biological response remains dependent on wavelength, dose, and clinical context. These settings are intended as supportive wellness tools rather than medical treatments.
Visum Light Tools in Veterinary Practice
Visum Light systems are designed as practical clinical tools that integrate easily into veterinary environments.
Hand-Held LED Controller
The hand-held unit allows targeted application to specific anatomical areas. This can be useful during in-clinic wellness sessions, rehabilitation visits, or post-procedure support appointments, including equine and mobile practice settings.
Flexible LED Pads
Flexible LED pads provide hands-free, evenly distributed light over larger anatomical regions. This approach may reduce handling time and restraint stress, particularly for animals that are anxious, sensitive, or undergoing longer sessions.
Pads may be used during supervised clinic visits or incorporated into guided home-use programs under veterinary direction.

Practice Differentiation and Service Expansion
Veterinary practices increasingly serve clients seeking non-invasive, drug-free care options. Incorporating a multi-wavelength LED photobiomodulation system may allow veterinarians to:
- Expand wellness and rehabilitation services
- Offer conservative support options for aging or medically complex animals
- Address nervous system and stress-related presentations
- Provide longer, calmer sessions with reduced restraint
- Differentiate the practice as current with evolving light-based technologies
Compared with older single-wavelength or high-powered laser systems, a flexible LED platform allows broader application across species and clinical contexts without the operational complexity associated with traditional laser therapy.
Practical Considerations for Clinical Use
- Non-invasive and non-thermal
- No ultraviolet emission
- Quiet operation
- Portable and clinic-friendly
- Suitable for supervised home use under veterinary guidance
These characteristics allow LED photobiomodulation to be integrated into veterinary clinics, rehabilitation practices, and wellness programs with minimal workflow disruption.
Safety and Intended Use
Visum Light is intended to support general animal wellness only.
It is not intended to diagnose, treat, cure, or prevent disease.
Veterinary clinical judgment should guide all applications.

See how Veterinarian and Pet Lover Dr. Steve Stewart of Pathways Holistic Petcare, London, Ontario, Canada uses his Visum Light in his Practice to Help his Clients and Animals...
Harry - 18 yr old
This is Harry who will be 18 in August. I have been using light therapy on him for a few years now. He was struggling with arthritis throughout, but with Visum Light and some TLC, he is staying stable and happy.
Gracie - 7 yr old
This is Gracie, a 7-year-old dog with a reccurring Rt cruciate ligament. After only 3 visits using the Visum Light, we have seen a noticeable improvement with her ligament.
Zues - 2yr old
Zues, a 2-year-old dog, had a fall and had a partial tear of Lt cruciate ligamnet. During his visits, we use the Visum Light on RB pulsating and RBGN Pain Mode on him for 6 minutes to help heal the tear.
17 yr old Paso Fino
17-year-old Pasafino is suffering from a Rt hip issue and Rt front lameness when he was brought to us. We used the Visum Light on RB Pulsating Mode and RBGN Pain Mode, as well as Anxiety Mode on him, along with Tui Na (spinal therapy) and CBD Oil 5000 mg taken daily. After 5 visits within a 3-week span, Pasafino is doing much better now than when he came in.
5 yr old mixed breed
5 yr old mix breed IVDD, using both the R B pulsating for 3-5 mins, coupled with pain mode 3-5 mins. Combined with the pinpoint laser on acupuncture points that correlate with IVDD. Noticing more feeling in the hind end since treatment started.
Monte - 11 yr old Arab
Several months ago, Monte who is an 11-year-old Arabian English Riding Champion, suffered from edema of the right hock. The misalignment of his Rt hip and a Lt shoulder dip contributed to this issue. After several visits using the Visum Light, along with some spinal therapy and massage, this ongoing issue has dramatically improved.
