Dual-Spectrum Cold Laser Wellness Device with 650nm & 808nm for Muscle & Joint Comfort | Lersk

Twenty-one diodes. Two wavelengths. One handheld device that goes where you need it.

This dual-spectrum cold laser wellness device combines 650nm visible red light and 808nm near-infrared light into a cordless, precision handheld unit designed for targeted daily use on muscles, joints, and soft tissue — anywhere on the body, including pets.

650nm Red Light — Surface Level Fifteen diodes at 5mW each deliver visible red light at the surface layer. Designed to support skin appearance, ease everyday surface stiffness, and complement the deeper infrared function during each session.

808nm Near-Infrared — Deep Reach Six diodes at 200mW each penetrate beneath the surface to reach deeper muscle and joint tissue. Designed for post-activity recovery, joint comfort, and releasing tension that surface-level treatments can't reach.

Fully Adjustable. Fully Cordless. Six power levels from 15% to 100% and a 5–30 minute adjustable timer let you tailor every session precisely. The 2600mAh rechargeable battery delivers true cordless freedom — at home, at the gym, or traveling.
