Protocol⁴ Small Pet Red Light Capsule — Five-Wavelength Red & Near-Infrared Light System

The Protocol⁴ Small Pet Red Light Capsule (P620) brings red and near-infrared photobiomodulation into a compact enclosed system designed specifically for small companion animals.

Inside the capsule, 120 LEDs—60 positioned on each side—surround the interior with five wavelengths of red and near-infrared light: 630, 660, 810, 830, and 850 nm.

With variable brightness control, automatic shutoff, a compact 31.3 lb design, and an enclosed hands-free format, the P620 provides a purpose-built alternative to positioning a pet in front of a conventional human-sized red-light panel.

Designed Specifically for Small Companion Animals

The P620 is designed around a smaller animal rather than adapting full-size human photobiomodulation equipment for pet use.

The enclosed design creates a defined resting space while light is delivered from both sides of the capsule. Protocol⁴'s product imagery shows the unit accommodating a small dog comfortably within the illuminated enclosure.

For pet owners already creating sophisticated wellness environments for themselves, the P620 provides a dedicated light-based system designed for the smaller members of the household.

Five Red + Near-Infrared Wavelengths

The Small Pet Red Light incorporates five wavelengths:

• 630 nm — Red
• 660 nm — Red
• 810 nm — Near-Infrared
• 830 nm — Near-Infrared
• 850 nm — Near-Infrared

The combination provides both visible red and near-infrared light within one compact system.

120 LEDs — 60 on Each Side

Rather than directing light toward the animal from a single external source, the P620 uses 120 lamp beads divided evenly between the two sides of the capsule.

That bilateral arrangement is one of the key advantages of the enclosure format: the pet can remain inside the defined space rather than requiring repeated repositioning in front of a conventional panel.

Variable Brightness Control

Light output isn't limited to one fixed brightness.

The P620 provides variable, knob-adjustable brightness, allowing the operating level to be adjusted directly on the system.

Protocol⁴ specifies optical power of greater than 200 mW/cm² at zero distance, with a 30° lens angle. Because actual exposure depends on factors including distance and positioning within the capsule, users should follow current manufacturer guidance rather than interpreting the zero-distance measurement as a recommended exposure level.

Built-In Timing Controls

The P620 includes a 30-minute factory auto-shutoff.

The specification sheet also identifies optional timer settings of:

10 / 15 / 25 / 40 minutes

The system does not use a pulse mode.

Compact, Purpose-Built Design

At approximately:

24.0"L × 17.5"W × 20.4"H

and weighing approximately:

31.3 lb

the P620 is considerably smaller than Protocol⁴'s human full-body photobiomodulation systems.

Its compact footprint makes it easier to incorporate into a home or dedicated pet-wellness area without requiring the space of a human-sized capsule or full-height panel.

Technical Specifications

Specifications are based on the current Protocol⁴ P620 specification sheet.

Pet Red Light vs. Human Red Light Equipment

Protocol⁴ also offers substantially larger photobiomodulation equipment for human use, including full-height panels and P4/P6 capsule systems.

The P620 serves a different purpose.

Rather than adapting human equipment to an animal, it provides:

A compact enclosure → light from both sides → adjustable brightness → built-in timing → pet-specific scale

That makes it a distinctive addition to the broader Protocol⁴ light-technology collection.

Important Pet Safety Information

Use the Protocol⁴ Small Pet Red Light according to current manufacturer instructions and appropriate veterinary guidance.

Pets should be supervised during use. Because animals cannot communicate discomfort or changes in vision, temperature, or light sensitivity in the same way a person can, owners should pay close attention to the animal's behavior throughout a session.

Consult an appropriate veterinarian before using light-based wellness equipment with an animal that has an illness, injury, eye or skin condition, pregnancy, photosensitivity, medication use, recent procedure, or other health concern.

The Small Pet Red Light Capsule is presented as pet wellness equipment and is not a substitute for veterinary diagnosis, treatment, or emergency care.

Protocol⁴ at Aurum Apex

The Protocol⁴ Small Pet Red Light Capsule P620 extends the brand's photobiomodulation collection into a compact system designed specifically for small companion animals.

With five wavelengths, 120 LEDs, bilateral light placement, adjustable brightness, integrated timing, and a compact enclosed format, it provides a purpose-built way to incorporate red and near-infrared light into a thoughtfully designed pet-wellness environment.
