Targeted 308nm UVB therapy
The ZJZK PD02W20 is a home phototherapy device that emits narrow-spectrum UVB light at a 308nm wavelength. It is designed for adults managing vitiligo, psoriasis, eczema and dermatitis. The handheld unit treats a 4cm² area using six medical diodes for precise lesion targeting.
Battery operation and dose control
An internal 1800mAh battery powers the device for portable sessions without a wall outlet. Intensity is fixed at 20mW/cm² while the dose adjusts from 0 to 5J/cm² and exposure time from 0 to 180 seconds. Typical sessions last one to three minutes, three to four times weekly.
Protective glasses and carry bag
The package includes safety goggles to shield eyes during treatment and a storage bag for the device, manual and power supply. These accessories enable immediate, organised home use and protect the hardware between sessions.

Questions about this item
How do I set up the PD02W20 for a treatment session and what step is often missed?
Charge the 1800mAh battery via the included power supply, select a dose between 0-5J/cm² and a time up to 180s, then put on the supplied protective glasses before activating the 308nm light.
What parts of the PD02W20 will need replacement or upkeep over time?
The six medical diodes deliver the 308nm UVB output; their intensity can diminish after extended use, and the 1800mAh rechargeable battery will eventually hold less charge and require replacement.
What limits the length of a single PD02W20 session during daily use?
Each session is capped at 180 seconds by the timer, and the total dose cannot exceed 5J/cm² at the fixed 20mW/cm² intensity, so the device stops automatically when either limit is reached.
