Home Cold Laser Therapy Device

The ZJZK unit delivers low-level laser therapy with three distinct wavelengths for drug-free pain management at home. It targets muscle soreness, joint inflammation, arthritis and sports injuries for adults and pets. The portable grey handset operates without heating tissue, relying on photochemical effects to stimulate cellular repair and reduce discomfort.

Three Wavelengths and Two Output Modes

The device combines 16 diodes at 660nm, 4 diodes at 810nm and 4 diodes at 980nm for a total of 24 emitters. Users select continuous wave or a 10Hz pulsed wave mode, with evidence suggesting pulsed output suits most applications except nerve regeneration. No external power pack or cooling system is required; the handheld form factor plugs in and treats the target area directly.

1760mW Total Output Under Sustained Use

Combined diode power reaches 1760mW, distributed as 10mW per 660nm diode and 200mW per near-infrared diode. The low power density avoids thermal buildup during extended sessions, maintaining photobiomodulation effects without overheating skin. Continuous or pulsed operation sustains consistent irradiance for the duration of each treatment cycle.
