[Product Introduction and Treatment Recommendations]
This laser therapy device is designed for physical therapy, therapeutic light therapy, and red light phototherapy to support pain relief and recovery. As a cold laser therapy device and low level laser therapy (LLLT) solution, it is suitable for muscle strain treatment and daily wellness care. The 2.8-inch touchscreen with stylus allows easy control, and 10 programs can be saved. For red light therapy for pain, recommended use is 3–5 sessions per week, with 5–20 minutes per area, adjusting intensity as needed.

[Wavelength Introduction]
This red laser therapy and near infrared light therapy device integrates 650nm, 808nm, 905nm, and 980nm wavelengths. 650nm supports red light laser therapy for superficial tissues. 808nm and 905nm provide deeper penetration for infrared red light therapy and nerve-related discomfort. 980nm delivers strong deep-tissue stimulation, commonly used in therapeutic laser therapy. These wavelengths make the device suitable for cold low level laser therapy and infrared light therapy devices applications.

[Application Scope Introduction]
Widely used in physical therapy and home care, this cold laser device supports low laser therapy for muscle soreness, joint stiffness, tendon discomfort, and sports recovery. It is suitable for home infrared light therapy, clinic-based rehabilitation, and wellness use. Common treatment areas include neck, shoulders, back, knees, elbows, wrists, and ankles. The device is ideal for users seeking laser red light therapy and red light therapy for pain in both acute and chronic conditions.

[Function Introduction]
This low level laser therapy LLLT device offers adjustable power from 200mW to 2500mW and treatment time from 1 to 60 minutes. It supports Continuous Wave (CW) mode for stable output and Pulsed Wave (PW) mode with adjustable frequency from 1–10000Hz, suitable for cold level laser therapy and nerve stimulation. Wavelengths can be selected and combined freely to customize therapeutic laser therapy sessions. The 3400mAh battery supports multiple treatments per charge.

[Packaging and After-Sales Service Introduction]
The package includes 1 cold laser therapy device, 1 AC adapter with charging cable, 1 pair of safety goggles, 1 user manual, and 1 product bag. Each unit is tested to ensure performance for infrared light therapy devices and red light phototherapy use. Professional after-sales support is provided, including operation guidance, technical assistance, and warranty service, ensuring safe and reliable use for home infrared light therapy and clinical applications.

Working Principles
650nm Red Laser Light
The 650nm red wavelength works on the skin's surface to promote local microcirculation. Commonly utilized for soothing surface irritation, calming skin redness, and supporting the body's natural healing response for minor wounds. This wavelength is often incorporated into wellness routines that align with traditional meridian-based approaches.
808nm Near-Infrared Laser Light
Invisible to human vision, the 808nm wavelength is engineered to reach deeper tissue layers. It aids in easing discomfort originating from deep muscles and joints, particularly beneficial for areas such as the knees, cervical spine, and shoulders. Frequently associated with enhancing mobility and alleviating occasional joint stiffness, this wavelength is widely adopted in therapeutic and recovery settings.
905nm Near-Infrared Laser Light
The 905nm wavelength provides substantial tissue penetration to encourage local circulation and support cellular function. It is frequently employed to assist in calming deep-seated inflammation, soothing muscle discomfort, and aiding the body's inherent recovery mechanisms—especially valuable in sports medicine and post-exercise regeneration.
980nm Near-Infrared Laser Light
Offering penetration beyond 808nm and 905nm, the 980nm wavelength reaches deeper musculature and vascular structures to target chronic inflammation and discomfort at the deepest tissue levels. Through photobiomodulation, it supports cellular function and local circulation without generating thermal effects. Well-suited for home therapy addressing multi-layered concerns such as deep muscle discomfort and persistent conditions, while also complementing care for surface-level needs.

Please Note
The 808nm, 905nm, and 980nm wavelengths are invisible to the unaided eye. Consequently, these diodes appear identical whether the device is active or inactive—this is standard and not indicative of any functional issue. Every unit undergoes rigorous quality inspection and professional testing prior to shipment. Verification of infrared output requires specialized detection equipment
