308nm UVB Phototherapy Light for Face, Neck & Limbs with 3 Interchangeable Lampshades | Lersk

UVB phototherapy is one of the most widely used light-based approaches in dermatological care — and 308nm is the specific wavelength most commonly associated with targeted skin light therapy. This portable 308nm UVB phototherapy device brings that same wavelength into a compact, wireless format designed for home use across multiple body areas.

Three Interchangeable Lampshades for Targeted Coverage

One of the most important factors in UVB phototherapy is matching the lampshade size to the treatment area. This device comes with three different lampshade sizes designed for different body areas:

The large lampshade (400mm²) is suited for broader areas such as the back, chest, or larger limb surfaces. The medium lampshade (254.4mm²) provides mid-range coverage for areas like the arms, legs, and shoulders. The small lampshade (78.5mm²) allows precise, targeted exposure for smaller or harder-to-reach areas such as the hands, neck, behind the ears, and facial areas.

Precise Dose Control

The device features a digitally programmed timer with dose control accurate to two decimal places — adjustable from 0.01 J/cm² to 5.00 J/cm². This level of precision allows you to follow a structured exposure protocol and increase dosage gradually over time.

Recommended starting dose is 0.1 J/cm², used every other day. Increase by 0.05 J/cm² per session. If redness occurs within 24 hours of a session, maintain the current dose without increasing further.

Safety Features

The device includes a built-in combination lock to prevent accidental activation by children or pets. Safety goggles are included and must be worn during every session to protect the eyes from UVB exposure.
