Cold Laser Therapy Device for Body Pain Relief and Muscle Recovery | Lersk

Portable cold laser therapy device designed for home and clinical use — intended to deliver dual-wavelength red and near-infrared light (650nm + 808nm) to targeted areas of the body. Equipped with 20 diodes at 880mW total output, adjustable power levels, and a rechargeable 3000mAh battery. Designed for use on humans and animals. Suitable for targeted application to muscles, joints, and soft tissue areas.

Dual-Wavelength Light Therapy — 650nm + 808nm Features two complementary wavelengths designed for different tissue depths. The 650nm red light (16 diodes × 5mW) is intended to address surface-level tissue, while the 808nm near-infrared light (4 diodes × 200mW) is designed to penetrate more deeply into muscle and joint tissue to support recovery.

880mW Output — 20 GaAlAs Diode Lasers Delivers a total output of 880mW through 20 GaAlAs diode lasers — a laser type commonly used in low-level laser therapy (LLLT) research and clinical applications. Designed for consistent, focused light delivery across the treatment area.

4-Level Adjustable Power Power output is adjustable at 25%, 50%, 75%, and 100% — designed to allow customized intensity depending on the treatment area and user preference.

Continuous and Pulsed Wave Modes Supports both continuous wave (CW) and pulsed wave (PW) modes, adjustable at 10Hz — designed to provide flexibility for different application needs.

1–60 Minute Adjustable Timer Built-in timer adjustable from 1 to 60 minutes — designed to support consistent session timing without requiring manual monitoring.

Rechargeable 3000mAh Battery Powered by a built-in 3000mAh lithium battery with DC charging support. Compatible with 100V–240V, 50/60Hz for worldwide use. Designed for cordless use during sessions.

Portable Handheld Design Compact at 21.7 × 6 × 5.4 cm — designed for targeted handheld application to specific body areas. Lightweight and travel-friendly.

Designed for Use On Humans and Animals Intended for use on a range of body areas including back, neck, shoulders, joints, and limbs. Also designed for use on pets including dogs, cats, horses, and rabbits.

Intended Application Areas — Back and neck discomfort — Joint and muscle recovery support — Sports-related soft tissue recovery — Shoulder and limb mobility support — General muscle relaxation and comfort
