Arthritis Therapy Flashlight, Joint Pain Treatment Device Red Light Therapy Device with 630nm, 660nm, and 850nm Triple LEDs to Promote Blood Circulation, Wound Healing, and Soft Tissue Repair

The JY-JY02-3H red light therapy flashlight delivers clinical-grade 630nm, 660nm, and 850nm wavelengths to penetrate skin, muscle, and joint tissues. Powered by a 2200mAh 18650 lithium battery with 3-5 hours of runtime, this portable device helps relieve arthritis pain, reduce inflammation, promote wound healing, and improve blood circulation – all without drugs or side effects. Suitable for seniors, drivers, and office workers suffering from neck, shoulder, lower back, and knee pain.

🔴 Tri-Band Red Light Technology – Three-Layer Penetration, Comprehensive Repair
Equipped with three high-power LED bulbs covering three key wavelengths:

Wavelength    Penetration Layer    Main Benefits
630nm: Epidermis    Promotes collagen production, improves skin texture, and accelerates healing of superficial wounds
660nm: Dermis    Reduces inflammation and swelling, relieves neuropathic pain, and promotes bone healing
850nm    : Subcutaneous Tissue and Muscle Layer    Penetrates deep into joints and muscle tissue, relieves deep-seated pain, and accelerates tissue repair
Red light and near-infrared light safely penetrate the skin; the 630nm and 660nm red light penetrate the dermis, while the 850nm infrared light reaches deep into subcutaneous and muscle tissue, delivering comprehensive therapy from the surface to the core.

IV. Target Users and Scenarios
Do you experience any of the following issues?
✅ Neck stiffness and shoulder tension
✅ Lower back pain and discomfort from prolonged sitting
✅ Leg joint pain and knee pain
✅ Soft tissue injuries and muscle strains
✅ Slow wound healing
✅ Arthritis, rheumatic pain

Particularly Suitable For:
Group: Reason
Middle-aged and elderly adults: A high-risk group for arthritis and rheumatic pain, requiring gentle, drug-free physical therapy
Drivers: Prolonged sitting leads to poor blood circulation in the cervical spine, lumbar spine, and legs
Office workers: Prolonged desk work commonly causes shoulder and neck soreness and lumbar muscle strain
Sports Enthusiasts:    Aids in recovery from muscle soreness and soft tissue injuries
Post-Surgery Patients: Promotes wound healing and accelerates tissue repair

V. Why Choose Red Light Therapy?
Red light therapy, also known as photobiomodulation (PBM), uses natural light at specific wavelengths between 600–850 nm to enhance cellular function and health. It contains no ultraviolet rays, causes no overheating, and has no side effects.

Scientific Principles:
Light is absorbed by the mitochondria in skin cells
Stimulates ATP (adenosine triphosphate) production, boosting cellular energy
Promotes the release of nitric oxide, dilates blood vessels, and improves microcirculation
Accelerates collagen synthesis and tissue repair

Clinically Proven Effects:
Relieves muscle soreness and joint stiffness
Reduces inflammation and swelling
Promotes blood flow
Accelerates wound healing and tissue regeneration
Improves metabolism and boosts immune function

VI. How to Use?
Install the battery: Insert the 18650 lithium battery into the battery sleeve, then place it into the flashlight
Turn on: Press the power button and select the desired mode
Application: Aim the light head at the painful area, keeping it approximately 5–10 cm from the skin
Timer: The device automatically shuts off after 5 minutes
Frequency: Use 1–3 times daily, 5 minutes per session
Charging: Connect the charger; a red light indicates charging, and a green light indicates a full charge

Important Notes:
For first-time use, start with short sessions and gradually increase duration
The treatment area must be fully exposed (do not use through clothing)
Do not look directly at the LED bulbs to avoid eye discomfort
If you are taking photosensitive medications (such as tetracycline or retinoic acid), please consult your doctor first
