Narrowband Phototherapy KN-4003BL2 UVB OLED Timer Display and Dust-Waterproof


“UVB” Narrowband “(UVB-NB) has become the phototherapy treatment of choice for psoriasis, vitiligo, atopic dermatitis (eczema), and other photoresponsive skin disorders, because it provides the largest amount of wavelength of the most beneficial UV light, also minimizing the wavelength potentially dangerous. UVB-Narrowband is theoretically safer and more effective than UVB-Broadband with a shorter irradiation time and maximum benefits.

KN-4003BL2 is a lightweight hand-held NB-UVB light therapy device, very convenient for patients to use at home or travel. The light source is the Philips PL-S 9W / 01-2P UV light series, where ’01’ is the phosphor code for 311nm narrowband uvb type light. This lamp is very stable and durable in use.
